Blowing it with Power Plant Retracts and Wall Blowers

(All right… right off the bat…. a run-on sentence the size of a paragraph… I can tell it’s going to be a long night).
To learn more about the dynamiters and shaking boiler tubes you can read the post: Cracking a boiled Egg in the Boiler. At other times while I was on the labor crew, I had heard these same benches making a tremendous sound that you could hear from a few landings away. It sounded like a large steam leak would sound, and at the same time, you could hear some kind of mechanical gears or something running and maybe a chain clanging. I didn’t really understand what the purpose these long benches served then, only that it was a good place to put the water jug and the box of fly ash suits to keep them from being stepped on.
It was after I had become an electrician that these long metal benches took on another meaning. I found out that they were called “Retracts”. I was told that they called them retracts because what they do is they run a long metal pipe into the boiler and then Retract it back. Ok. I thought it was rather odd to name something for a seemingly insignificant part of the function. After I understood what they were used for, I thought I could come up with a lot better name than “Retract”.
After all, we had equipment like “Honey Wagon” , “Coffin Houses”, “Clinker Grinder”. All really descriptive names. So, when Charles Foster told me to go with Diane Lucas (later Diane Brien) to work on 7R retract, I was expecting to go find some little lever going back and forth making a sound like “brrrr…oops…..brrr…..oops” as it swung back and forth. I would name something like that a “Retract”.
Actually, I would like to have been able to have kept a couple of Retracts in my pocket so that when I would smart off to Leroy Godfrey our Electrical Supervisor, I could pull one out and press the button and… “swoop”! Retracted!
So, what is a Retract? Well. In the story that I linked to above about the cracked egg in the boiler, I explained how when I was on the labor crew we had to go in the boiler and tie ropes to these hanging boiler tubes and then shake them back and forth to clean out the hard ash that had built up on them. Well, The Retract would sort of do that when the boiler was online. They would clean out the tubes in the reheat area of the boiler for the most part.

What it would do is this. It seemed like 7R retract was about 40 feet long (someone at the plant can correct me if I’m wrong about the length). When it would turn on, it would start rotating a pipe about that long and start pushing it into the boiler. Once the nozzle at the end of the pipe was in the boiler a couple of feet steam would start blasting down the pipe to the nozzle on the end that would shoot the steam out at right angles to the pipe. As the pipe rotated, it would be shooting out steam in a circular motion as the pipe slowly traversed into the boiler.
You see… My dentist told me a long time ago that I should Floss my teeth more if I didn’t want to wear dentures when I was older. By keeping the bits of food out from between my teeth, not only did my breath smell better, but my gums could remain healthy as well. So, I listened to him and started flossing. Retracts are kind of like that.
The Retracts were designed to clean out the areas of the boiler where the ash would build up the most causing the efficiency of the boiler to be degraded. So at certain times of the day, the Control Room operator will push a button on the side panel (at least that was what they used to do… now they probably click an icon on their computer) and it would start the cycle of the retracts going in and out one at a time cleaning out the boiler.
This is a drawing of a Steam retract for a boiler. I added the Chinese characters in the drawing for my Asian readers… no, not really. Sorry the picture is a little small
Anyway. I finally learned what those long metal benches were for and it fascinated me. I wonder how long it took before someone said what now would seem obvious…. “Hey. Instead of having to bring the boiler offline every week or so, how about if we just create this boiler flossing equipment that cleans the boiler out while it is online?”
It made me wonder about the other equipment around the plant. I’ll bet there was a good use for just about everything. And you know what? I think I was right. Instead of just putting all that equipment all over the place for us to play on like a big jungle gym, everything seemed to have a real good purpose.
After 4 years working as a summer help, and one more year as a janitor and on the labor crew, I thought I had seen just about everything in the plant. When I became an electrician, all of the sudden a whole new world opened up to me. Even that bench I had been sitting on turned into a monster machine that blasted away ash clinkers while the rest of us lay at home in our beds dreaming of chocolate, and dragons, and um… other things people dream about.
So, what about the Wall Blower? Well. These are like the retracts, only they are much smaller. they were placed around the walls of the main boiler at strategic locations to blast clinkers that may be building up along the main wall of the boiler. The area in the boiler diagram up above called the Water Wall.
For some reason (and I’m sure it’s a good one), From what was called floor 6 1/2, though it was actually about the 13th floor, on down was an area called the “Boiler Enclosure”. This meant that when you walked up to the boiler, you first had to go through a door and enter an enclosed area around the boiler. 7th floor and above, the boiler was outside.
I’ve been to plants where the entire boiler was enclosed, and I’ve seen some that didn’t look like any of it was enclosed, so I figure this was a happy median between the two. It meant that if it was raining outside and you needed to work on the boiler, it made a big difference how high up you had to go as to whether you needed your rain suit or not.
I mention this because one day I had to go by myself to work on a wall blower that was on the 6 and 1/2 floor just at the top of the boiler enclosure. The wall blower was naturally situated right next to the boiler. and all the heat generated from the boiler and the piping that came from the bowl mills that blew the coal into the furnace had made the area very hot. The Wall blower had been tripping the breaker and I was supposed to go fix it.
I brought an infrared temperature gun with me and found that the area where the wall blower was mounted was 160 degrees. Maybe it was that high because it was the middle of a hot summer day, and with everything else going on, all the heat trapped right at the top of the boiler enclosure, it had just turned into a huge easy-bake oven.
When I touched the metal door to the control panel on the side of the wall blower, it burned my fingers. I had to use my tee-shirt as a rag to keep from burning myself. I could only stand next to the wall blower for about 30 seconds and then I had to walk back over the doorway and breathe some fresh air and cool off for a minute before going back.
After opening the control panel, I could see what the problem was right away. The insulation on the wires going to the terminal block had the insulation dripping off the wires. The insulation was melting.
I went back to the shop and found some wire that was designed for high temperatures, because obviously someone had used the wrong type of wire when assembling this particular wall blower, given it’s location on the boiler.
High Temperature Wire
Because of the intense heat where I was standing when trying to rewire the wall blower, I was not able to take very big breaths. I had to breathe very shallow, or not at all. So, I would go up to the blower and work as fast as I could removing a screw or putting a new wire down and then I would go back to the doorway about 60 feet from the wall blower and cool off.
As I mentioned in the post about the Luxuries and Amenities of a Power Plant Labor Crew, when you are in this intense heat, your hardhat becomes soft like a baseball cap. In this case, I wasn’t in the heat long enough for this to happen, though I was sweating like a pig.
I had been doing this for a while when an operator showed up wondering what I was doing. His name was Jim Waller and he had been watching me from a distance. He said he was trying to figure out what I was up to because he would see me show up at the doorway and stand there for a while not doing anything, then turning around like I had forgotten something only to show up again about 1/2 minute later.
When he couldn’t figure out what I was doing on his own, he decided to take a closer look. I found him standing at the doorway waiting for me to arrive with a puzzled look on his face. I was tempted to just say nothing and just stand there and take a few breathes and then go back to the wall blower and continue my work.
I couldn’t do that however, when Jim asked me what I was doing. Jim was one of the nicest and most normal operators you could run across. I just couldn’t joke with him (as if he was Gene Day). So, I told him I was working on that wall blower over there, but that it was so hot that I had to keep coming to the doorway to cool off.
Jim Waller had come to work for the electric company a month before I began my last summer as summer help in 1982. At the time that I was working on the wall blower in 1984 I was just about to become 24 years old, and a couple of months later, he was going to be 29. Like Gene Day, you instantly knew when you saw Jim that he you liked him. He sort of had that Jim Nabors kind of smile.
Jim Waller reminded me of Jim Nabors when he was younger. He had the same likable demeanor.
Unlike Gene Day, I never felt like playing a joke on Jim. For some reason, Jim just seemed like too nice of a guy. Where Gene had a slight sort of hidden orneriness about him, Jim was just purely a “good guy”.
This past Christmas eve, five days before Jim turned 57 years old, he passed away after a sudden illness. When the guys at the power plant told me about it, I was sad for their loss and for his family. For Jim, on the other hand…. I think he has always had one foot in heaven from the day I met him. I think he finally stepped the rest of the way through the gate.
For someone like me. If I am ever able to make it to heaven, I’m sure there will be a big to-do about it, because someone would have won the pot and I’m sure the odds would have been high against it. However, the day Jim arrived, it was probably more like “business as usual”. — “Oh, Jim’s arrived….. Like no one didn’t see that coming….” If I could say something to Jim now (and being Catholic, I’m allowed to do that), I would ask Jim, “Put in a good word for all the Power Plant Men!” Because I know that Jim’s word is as good as gold. Here is a real picture of Jim, a true Power Plant Man:
Jim Waller, a True Power Plant Man!
Comment from the original post:
Good post on Jim, Kevin. Now, what is a “normal operator”? 🙂
I remember doing several jobs in super hot areas where I had to wear a heavy coat and gloves to keep from getting burned. Had to take off rings and wrist watch too. Needed to take off my glasses, but then I couldn’t see.
Solving the Selection of a Power Plant Solvent
A year after I joined the electricians in the electric shop, Howard Chumbley became my foreman. One day when we were talking about going to the old Osage Plant up the road to clean up a PCB (Polychlorinated Biphenyls) spill, he explained that “In His Day” they used to clean their tools in a vat of transformer oil that was full of PCBs. I remember him telling us that it was normal for him to be up to his elbows in the stuff. They never thought it might be harmful. Now we were getting ready to go up to the old plant to clean up a small spill and I was going to have to suit up in a special hazardous waste suit. I wrote about our experience in the post: “Pioneers of Power Plant Fame Finally Find Peace“.
Now we know about the hazard of developing cancer by having PCBs in your system. Today we know a lot of things we didn’t know back then. We know that Asbestos causes Mesothelioma. We know that Chlorofluorocarbons (CFC) destroy the ozone layer. We know that Twinkies are one of the few foods that will be around after a nuclear holocaust.
Years before I became an electrician, the Electric Company had stopped using oil with PCBs. There was still an effort to clean it up from the older plants. At the new coal-fired power plant in north central Oklahoma, we didn’t have a problem with PCBs. We had other problems. Some of which we didn’t know about (well, we knew something, just not so much) at the time.
A very prominent responsibility of mechanics and electricians was to clean oily equipment. Pumps and motors, breakers, fans, mills. All kinds of equipment. Almost everything was lubricated one way or another with oil. Solvent was used to remove the oil when the equipment needed to be cleaned.
We had a standard kind of solvent at our plant. I believe it was called “Standard Solvent 350”. See…. It was a Standard solvent. Even had the word Standard in the name. One of the key ingredients of this standard solvent is a solvent known as “Stoddard Solvent”. This solvent worked real good when cleaning up equipment like motors and pumps and other oily equipment. Many times we were “Up to our elbows” in this solvent.
We had a barrel in the corner of the electric shop close to the door to the main switchgear where we could put a motor and scrub it clean while solvent poured out of a flexible nozzle on the motor, your shirt, your pants, your work boots, and the floor. Some days during overhauls when we would work cleaning motors for 10 hours each day, I would come home from work drenched in solvent. My wife would make me take my clothes off in the utility room where I could put them directly into the washing machine where Oxydol could go to work on it right away.
When Ted Riddle and I were working for Willard Stark on an overhaul at the gas plant outside Mustang Oklahoma during the spring of 1986, Willard said one day that he wanted to show us something. I explained Willard’s situation at the plant in a post called “Working Power Plant Wonders with Willard Stark“.
He was a good example of what I would call a “Contrarian.” That is, he seemed to buck the system often. He thought outside the box a lot. I realized this right way when we would listen to Paul Harvey on the radio during lunch. Every time Paul Harvey would say, “…Noon News and Comment” Willard would always finish the sentence by saying, “Mostly Comment.” I figured then that he had to be a contrarian, because who would ever think that Paul Harvey wasn’t the best person in the world to bring the News to our private little power plant world.
Paul Harvey was one of a kind radio personality. No one will ever fill his shoes.
So, when Willard said he was wanted us to see something “with our own eyes”, I figured this was going to be something good. Probably some kind of secret place where you could hide and take a nap if the day wore on too long, or something like that. Well… It didn’t turn out to be that kind of “something”, but it was something.
Willard took a small metal pan and put some Stoddard Solvent in it. The old gas plant used straight Stoddard Solvent, unlike the more sophisticated Coal-fired plant where Ted Riddle and I normally worked. We walked out into the turbine-generator (T-G) floor. He placed the pan of solvent on the floor, took a WypAll (which is a strong paper rag) and dropped it into the pan:
A package of an Important Power Plant Staple: WypAlls!
Then he bent down and with his lighter, he lit the WypAll on fire. We watched as the flames grew higher and higher. Willard watched our expressions. We had been under the understanding that Solvent was not flammable. He explained that technically, Stoddard Solvent is not considered “Flammable”, but it is considered “Combustible”. Combustible means that it burns.
A bucket of Stoddard Solvent. Notice this bucket clearly says “Combustible”
Stoddard Solvent doesn’t ignite fast enough to be considered “Flammable”. At least that’s the way Willard explained it to us. Willard said he wanted us to be aware of this fact when we have our bodies all soaked in solvent, that if we were to catch on fire for some reason, we were going to go up in flames just like that WypAll. We both appreciated the advice.
I didn’t begin this post expecting to say that much about Stoddard Solvent, but just in case you were really wondering what it is, maybe this picture will explain it to you:
A Chemist-eye view of Stoddard Solvent
I hope that cleared it up for you. You have to wonder why they put that “Oh Oh” down there at the bottom. Almost as if something is supposed to go wrong.
The solvent I really wanted to talk about was one that was used more exclusively in the electric shop. It is called Trichloroethylene 1.1.1. You see, a lot of equipment that we cleaned in the electric shop needed to be cleaned spotless. Solvent 350 would leave a film when it dried. So, in the electric shop when we needed to clean something with electric contacts we would use something called “Electro Contact Cleaner”:
Spray Can of LPS Electro Contact Cleaner – Only the cans we used didn’t say CFC Free
This was very expensive compared to the regular solvent. So, I was surprised when Ben Davis and I first went on an overhaul in Muskogee, and they had this exact same contact cleaner in 55 gallon barrels:
Barrel of LPS Electro Contact Cleaner
I remember John Manning showing us a few of these barrels that they had ordered for the overhaul. I think my jaw dropped. By my calculation, one barrel like this would cost over $3,000.00. I figured if it was in cans, it would have cost three times that amount. The advantage of using Contact cleaner was that it dried clean. It didn’t leave a residue.
Trichloroethylene 1.1.1 was like that. It didn’t leave a residue when it dried. I think this will become obvious to you when you see what it really is:
Chemical Composition of Trichoroethylene
You can see right off the bat that this is going to dry clean… I mean…. it’s obvious… right? I think the CLs on three of the corners indicate that it “Cleans” 3 times better than other solvents.
Anyway. This stuff evaporated quickly so when you were up to your elbows in this solvent, it felt cool because it would evaporate causing a cooling effect. It had a very peculiar smell. It also made you feel a little dizzy when you were using it. Especially when you had to breathe in a lot of it in a confined area. Having fans blowing on you seemed to make it worse, because it would increase the evaporation rate filling the air with more solvent.
It was known at the time that Trichloroethylene would destroy your liver when it gets into your blood stream. There was no quicker way of injecting the solvent into your blood stream than by inhaling it. Finally OSHA decided that this solvent was no longer safe to be used in a plant setting. It could only be used in small quantities like “White Out”.
Gee… Who remembers White Out?
A bottle of White Out. Oh look. A New Formula!
The last time I heard about white out was in a blonde joke about someone using white out on the computer monitor. Who types anymore on a typewriter? I think anyone today that would choose to type on a typewriter would be the type of person that would prefer a typewriter eraser over white out.
I take that back. The last time I heard about White Out was on a show like 60 Minutes where they were showing young kids in Panama or another Central American country being hooked on tubs of White Out. They would sit around all day taking quick whiffs from a tub of White Out. — Why? Because it contained Trichloroethylene and it would give you a buzz.
My dad, a Veterinary professor at Oklahoma State University had told me about the dangers of Trichloroethylene around the time I told him about Bill McAlister using WD-40 on his elbows to ease the pain of his arthritis. Sonny Karcher had asked me to talk to my dad about it to see if he knew why WD-40 would help Arthritis.
My father (I’ll call him Father in this paragraph, because in this paragraph, he’s being more “sophisticated”) told me that WD-40 had the same chemical in it that Veterinarians used on horses to help their joints when they hurt. Then he warned me that the solvent in WD-40 soaks right into your skin and when it does it carries other toxic chemicals into your body than just the arthritis lineament. So, he told me to tell Sonny not to use it often.
A can of Power Plant WD40
So, anyway, we had to find a replacement for Trichloroethylene. Tom Gibson and Bill Bennett went to work ordering samples of other kinds of solvents that salesmen were saying would be a good replacement. One of the first that we tried was called Orange Solvent. It had a real nice Orange smell. Sort of like drinking Tang.
Bottle of Orange Solvent
It had a couple of problems. First, I would be more inclined to drink it since it smelled so good, and I was a fan of Tang at the time.
Tang – Used by the Astronauts on the Apollo missions
The second problem with the Orange Solvent was that it didn’t seem to clean very well. We were used to something cutting the oil and contact grease quickly. the Orange Solvent didn’t cut the mustard (so to speak).
One day during overhaul at our plant, Bill Bennett gave us a barrel of some new kind of solvent. It was supposed to be comparable in it’s cleaning ability to Trichloroethylene (could you imagine Red Skelton trying to say that word?)
Red Skelton saying “Trichloroethylene”
Bill wanted Andy Tubbs and me (I know! It seems as if it should be “Andy Tubbs and I”, but “me” is the correct way to say it) to use the new solvent on the main power transformer main bus connectors. They are normally covered with No-Ox Grease so this would be a good test.
A jar of No-Ox Grease (No-Ox means No Oxide)
So, Andy and I carried the large extension ladder out to the Unit 1 Main Power Transformer and leaned it up against the back side (the transformer’s backside, not ours). We climbed up to the open hatchways and crawled in. We hung a small yellow blower in the doorway to blow fresh air on us.
A Main Power Transformer
Andy and I had everything setup and we were ready to work. We both just fit in the small area with the large bus work between us. We began using our rags soaked in the new solvent on the silver plated bus. I don’t remember how well the solvent cleaned the bus. I just remember thinking that this solvent sure did evaporate quickly. Especially with the blower fan right next to us.
I also remember looking over at Andy crouched across from me. He was looking down at the bus. Then his entire body seemed to swivel around as if he was on some kind of swing which caused him to tilt up the side of the enclosure. I watched his face, and he seemed to be saying something to me, only I couldn’t make it out.
I think I said something like “Huh?” Then about that time all kinds of brightly lit flowers were circling around my head and my arms seemed to be floating in front of me. I heard Andy say with a slur, “We butter git outta here…” His voice sounded like it was in a pipe…. Well, we sort of were sitting in a pipe… He started to move toward the hatchway.
I remember briefly thinking that I was just fine enjoying the interesting scenery. By now there were bright lights streaming toward me from all sides. Then I thought. “No. I better leave.” So, I struggled to pull myself into the hatchway. It was big enough that we could both pull ourselves out together.
I began climbing down the ladder head first. It was about 15 feet to the ground. I was completely out of the hatch with my body completely upside down on the ladder before I decided that it would be better if I turned over and went down feet first. Somehow I managed to swing my feet down and around without falling off the ladder. I think Andy was pretty much in the same predicament as I was.
Once we were on the ground, we hobbled into the electric shop and sat down. We told Bill Bennett that this was not a good solvent to use. I don’t even want to remember what the name of the solvent was. If I mentioned it, someone may put it in some tubs of white out and sell it to kids in Panama, because Trichloroethylene had nothing on this.
I suppose we finally found a replacement solvent. Though, I don’t remember what it was. All I do know is that it was quite an adventure trying to find one. Maybe we just used a lot of Electro contact cleaner after that.
Like Howard Chumbley, who told stories about being up to his elbows in transformer oil made with PCBs, I can now tell my fellow teammates at work, “Yeah. I remember the days when we were up to our elbows in Trichloroethylene. Never gave it a second thought.” Only, their reaction would be a little different than ours were in the electric shop office. They might raise their eyes up from their computer monitors and look across the cubicle at me for a moment. Then give me a look like “there goes that crazy old guy that used to work in a power plant again. Hasn’t he told us that story about 50 times already?” Well…. That solvent and stuff. It makes you forget things…. I can’t remember what I have already said.

If that Trichloroethylene caused you to have some memory loss today, I can’t even begin to imagine what your memory was like before the exposure. I don’t know of anyone with a memory like yours! I mean – who else can remember the shoe size of his cub scout leader’s nephew’s neighbor?
I have a bottle of White-out in my desk today and use it regularly. I play an Eb Contra Bass Clarinet. Most of the music we play is not scored for my instrument so I’ll use Tuba, String Bass, Cello, Bassoon, etc. music (all in “C”) and transpose it to Eb. It takes a little White-out sometimes.
I love Saturday mornings!

After opening the control panel, I could see what the problem was right away. The insulation on the wires going to the terminal block had the insulation dripping off the wires. The insulation was melting.
I went back to the shop and found some wire that was designed for high temperatures, because obviously someone had used the wrong type of wire when assembling this particular wall blower, given it’s location on the boiler.
High Temperature Wire
Because of the intense heat where I was standing when trying to rewire the wall blower, I was not able to take very big breaths. I had to breathe very shallow, or not at all. So, I would go up to the blower and work as fast as I could removing a screw or putting a new wire down and then I would go back to the doorway about 60 feet from the wall blower and cool off.
As I mentioned in the post about the Luxuries and Amenities of a Power Plant Labor Crew, when you are in this intense heat, your hardhat becomes soft like a baseball cap. In this case, I wasn’t in the heat long enough for this to happen, though I was sweating like a pig.
I had been doing this for a while when an operator showed up wondering what I was doing. His name was Jim Waller and he had been watching me from a distance. He said he was trying to figure out what I was up to because he would see me show up at the doorway and stand there for a while not doing anything, then turning around like I had forgotten something only to show up again about 1/2 minute later.
When he couldn’t figure out what I was doing on his own, he decided to take a closer look. I found him standing at the doorway waiting for me to arrive with a puzzled look on his face. I was tempted to just say nothing and just stand there and take a few breathes and then go back to the wall blower and continue my work.
I couldn’t do that however, when Jim asked me what I was doing. Jim was one of the nicest and most normal operators you could run across. I just couldn’t joke with him. So, I told him I was working on that wall blower over there, but that it was so hot that I had to keep coming to the doorway to cool off.
Jim Waller had come to work for the electric company a month before I began my last summer as summer help in 1982. At the time that I was working on the wall blower in 1984 I was just about to become 24 years old, and a couple of months later, he was going to be 29. Like Gene Day, you instantly knew when you saw Jim that he you liked him. He sort of had that Jim Nabors kind of smile.
Jim Waller reminded me of Jim Nabors when he was younger. He had the same likable demeanor.
Unlike Gene Day, I never felt like playing a joke on Jim. For some reason, Jim just seemed like too nice of a guy. Where Gene had a slight sort of hidden orneriness about him, Jim was just purely a “good guy”.
This past Christmas eve, five days before Jim turned 57 years old, he passed away after a sudden illness. When the guys at the power plant told me about it, I was sad for their loss and for his family. For Jim, on the other hand…. I think he has always had one foot in heaven from the day I met him. I think he finally stepped the rest of the way through the gate.
For someone like me. If I am ever able to make it to heaven, I’m sure there will be a big to-do about it, because someone would have won the pot and I’m sure the odds would have been high against it. However, the day Jim arrived, it was probably more like “business as usual”. — “Oh, Jim’s arrived….. Like no one didn’t see that coming….” If I could say something to Jim now (and being Catholic, I’m allowed to do that), I would ask Jim, “Put in a good word for all the Power Plant Men!” Because I know that Jim’s word is as good as gold. Here is a real picture of Jim, a true Power Plant Man:
Jim Waller, a True Power Plant Man!
Comment from the original post:
Good post on Jim, Kevin. Now, what is a “normal operator”? 🙂
I remember doing several jobs in super hot areas where I had to wear a heavy coat and gloves to keep from getting burned. Had to take off rings and wrist watch too. Needed to take off my glasses, but then I couldn’t see.
Solving the Selection of a Power Plant Solvent
A year after I joined the electricians in the electric shop, Howard Chumbley became my foreman. One day when we were talking about going to the old Osage Plant up the road to clean up a PCB (Polychlorinated Biphenyls) spill, he explained that “In His Day” they used to clean their tools in a vat of transformer oil that was full of PCBs. I remember him telling us that it was normal for him to be up to his elbows in the stuff. They never thought it might be harmful. Now we were getting ready to go up to the old plant to clean up a small spill and I was going to have to suit up in a special hazardous waste suit. I wrote about our experience in the post: “Pioneers of Power Plant Fame Finally Find Rest“.
Now we know about the hazard of developing cancer by having PCBs in your system. Today we know a lot of things we didn’t know back then. We know that Asbestos causes Mesothelioma. We know that Chlorofluorocarbons (CFC) destroy the ozone layer. We know that Twinkies are one of the few foods that will be around after a nuclear holocaust.
Years before I became an electrician, the Electric Company had stopped using oil with PCBs. There was still an effort to clean it up from the older plants. At the new coal-fired power plant in north central Oklahoma, we didn’t have a problem with PCBs. We had other problems. Some of which we didn’t know about (well, we knew something, just not so much) at the time.
A very prominent responsibility of mechanics and electricians was to clean oily equipment. Pumps and motors, breakers, fans, mills. All kinds of equipment. Almost everything was lubricated one way or another with oil. Solvent was used to remove the oil when the equipment needed to be cleaned.
We had a standard kind of solvent at our plant. I believe it was called “Standard Solvent 350”. See…. It was a Standard solvent. Even had the word Standard in the name. One of the key ingredients of this standard solvent is a solvent known as “Stoddard Solvent”. This solvent worked real good when cleaning up equipment like motors and pumps and other oily equipment. Many times we were “Up to our elbows” in this solvent.
We had a barrel in the corner of the electric shop close to the door to the main switchgear where we could put a motor and scrub it clean while solvent poured out of a flexible nozzle on the motor, your shirt, your pants, your work boots, and the floor. Some days during overhauls when we would work cleaning motors for 10 hours each day, I would come home from work drenched in solvent. My wife would make me take my clothes off in the utility room where I could put them directly into the washing machine where Oxydol could go to work on it right away.
When Ted Riddle and I were working for Willard Stark on an overhaul at the gas plant outside Mustang Oklahoma during the spring of 1986, Willard said one day that he wanted to show us something. I explained Willard’s situation at the plant in a post called “Working Power Plant Wonders with Willard Stark“.
He was a good example of what I would call a “Contrarian.” That is, he seemed to buck the system often. He thought outside the box a lot. I realized this right way when we would listen to Paul Harvey on the radio during lunch. Every time Paul Harvey would say, “…Noon News and Comment” Willard would always finish the sentence by saying, “Mostly Comment.” I figured then that he had to be a contrarian, because who would ever think that Paul Harvey wasn’t the best person in the world to bring the News to our private little power plant world.
Paul Harvey was one of a kind radio personality. No one will ever fill his shoes.
So, when Willard said he was wanted us to see something “with our own eyes”, I figured this was going to be something good. Probably some kind of secret place where you could hide and take a nap if the day wore on too long, or something like that. Well… It didn’t turn out to be that kind of “something”, but it was something.
Willard took a small metal pan and put some Stoddard Solvent in it. The old gas plant used straight Stoddard Solvent, unlike the more sophisticated Coal-fired plant where Ted Riddle and I normally worked. We walked out into the turbine-generator (T-G) floor. He placed the pan of solvent on the floor, took a WypAll (which is a strong paper rag) and dropped it into the pan:
A package of an Important Power Plant Staple: WypAlls!
Then he bent down and with his lighter, he lit the WypAll on fire. We watched as the flames grew higher and higher. Willard watched our expressions. We had been under the understanding that Solvent was not flammable. He explained that technically, Stoddard Solvent is not considered “Flammable”, but it is considered “Combustible”. Combustible means that it burns.
A bucket of Stoddard Solvent. Notice this bucket clearly says “Combustible”
Stoddard Solvent doesn’t ignite fast enough to be considered “Flammable”. At least that’s the way Willard explained it to us. Willard said he wanted us to be aware of this fact when we have our bodies all soaked in solvent, that if we were to catch on fire for some reason, we were going to go up in flames just like that WypAll. We both appreciated the advice.
I didn’t begin this post expecting to say that much about Stoddard Solvent, but just in case you were really wondering what it is, maybe this picture will explain it to you:
A Chemist-eye view of Stoddard Solvent
I hope that cleared it up for you. You have to wonder why they put that “Oh Oh” down there at the bottom. Almost as if something is supposed to go wrong.
The solvent I really wanted to talk about was one that was used more exclusively in the electric shop. It is called Trichloroethylene 1.1.1. You see, a lot of equipment that we cleaned in the electric shop needed to be cleaned spotless. Solvent 350 would leave a film when it dried. So, in the electric shop when we needed to clean something with electric contacts we would use something called “Electro Contact Cleaner”:
Spray Can of LPS Electro Contact Cleaner – Only the cans we used didn’t say CFC Free
This was very expensive compared to the regular solvent. So, I was surprised when Ben Davis and I first went on an overhaul in Muskogee, and they had this exact same contact cleaner in 55 gallon barrels:
Barrel of LPS Electro Contact Cleaner
I remember John Manning showing us a few of these barrels that they had ordered for the overhaul. I think my jaw dropped. By my calculation, one barrel like this would cost over $3,000.00. I figured if it was in cans, it would have cost three times that amount. The advantage of using Contact cleaner was that it dried clean. It didn’t leave a residue.
Trichloroethylene 1.1.1 was like that. It didn’t leave a residue when it dried. I think this will become obvious to you when you see what it really is:
Chemical Composition of Trichoroethylene
You can see right off the bat that this is going to dry clean… I mean…. it’s obvious… right? I think the CLs on three of the corners indicate that it “Cleans” 3 times better than other solvents.
Anyway. This stuff evaporated quickly so when you were up to your elbows in this solvent, it felt cool because it would evaporate causing a cooling effect. It had a very peculiar smell. It also made you feel a little dizzy when you were using it. Especially when you had to breathe in a lot of it in a confined area. Having fans blowing on you seemed to make it worse, because it would increase the evaporation rate filling the air with more solvent.
It was known at the time that Trichloroethylene would destroy your liver when it gets into your blood stream. There was no quicker way of injecting the solvent into your blood stream than by inhaling it. Finally OSHA decided that this solvent was no longer safe to be used in a plant setting. It could only be used in small quantities like “White Out”.
Gee… Who remembers White Out?
A bottle of White Out. Oh look. A New Formula!
The last time I heard about white out was in a blonde joke about someone using white out on the computer monitor. Who types anymore on a typewriter? I think anyone today that would choose to type on a typewriter would be the type of person that would prefer a typewriter eraser over white out.
I take that back. The last time I heard about White Out was on a show like 60 Minutes where they were showing young kids in Panama or another Central American country being hooked on tubs of White Out. They would sit around all day taking quick whiffs from a tub of White Out. — Why? Because it contained Trichloroethylene and it would give you a buzz.
My dad, a Veterinary professor at Oklahoma State University had told me about the dangers of Trichloroethylene around the time I told him about Bill McAlister using WD-40 on his elbows to ease the pain of his arthritis. Sonny Karcher had asked me to talk to my dad about it to see if he knew why WD-40 would help Arthritis.
My father (I’ll call him Father in this paragraph, because in this paragraph, he’s being more “sophisticated”) told me that WD-40 had the same chemical in it that Veterinarians used on horses to help their joints when they hurt. Then he warned me that the solvent in WD-40 soaks right into your skin and when it does it carries other toxic chemicals into your body than just the arthritis lineament. So, he told me to tell Sonny not to use it often.
A can of Power Plant WD40
So, anyway, we had to find a replacement for Trichloroethylene. Tom Gibson and Bill Bennett went to work ordering samples of other kinds of solvents that salesmen were saying would be a good replacement. One of the first that we tried was called Orange Solvent. It had a real nice Orange smell. Sort of like drinking Tang.
Bottle of Orange Solvent
It had a couple of problems. First, I would be more inclined to drink it since it smelled so good, and I was a fan of Tang at the time.
Tang – Used by the Astronauts on the Apollo missions
The second problem with the Orange Solvent was that it didn’t seem to clean very well. We were used to something cutting the oil and contact grease quickly. the Orange Solvent didn’t cut the mustard (so to speak).
One day during overhaul at our plant, Bill Bennett gave us a barrel of some new kind of solvent. It was supposed to be comparable in it’s cleaning ability to Trichloroethylene (could you imagine Red Skelton trying to say that word?)
Red Skelton saying “Trichloroethylene”
Bill wanted Andy Tubbs and me (I know! It seems as if it should be “Andy Tubbs and I”, but “me” is the correct way to say it) to use the new solvent on the main power transformer main bus connectors. They are normally covered with No-Ox Grease so this would be a good test.
A jar of No-Ox Grease (No-Ox means No Oxide)
So, Andy and I carried the large extension ladder out to the Unit 1 Main Power Transformer and leaned it up against the back side. We climbed up to the open hatchways and crawled in. We hung a small yellow blower in the doorway to blow fresh air on us.
A Main Power Transformer
Andy and I had everything setup and we were ready to work. We both just fit in the small area with the large bus work between us. We began using our rags soaked in the new solvent on the silver plated bus. I don’t remember how well the solvent cleaned the bus. I just remember thinking that this solvent sure did evaporate quickly. Especially with the blower fan right next to us.
I also remember looking over at Andy crouched across from me. He was looking down at the bus. Then his entire body seemed to swivel around as if he was on some kind of swing which caused him to tilt up the side of the enclosure. I watched his face, and he seemed to be saying something to me, only I couldn’t make it out.
I think I said something like “Huh?” Then about that time all kinds of brightly lit flowers were circling around my head and my arms seemed to be floating in front of me. I heard Andy say with a slur, “We butter git outta here…” His voice sounded like it was in a pipe…. Well, we sort of were sitting in a pipe… He started to move toward the hatchway.
I remember briefly thinking that I was just fine enjoying the interesting scenery. By now there were bright lights streaming toward me from all sides. Then I thought. “No. I better leave.” So, I struggled to pull myself into the hatchway. It was big enough that we could both pull ourselves out together.
I began climbing down the ladder head first. It was about 15 feet to the ground. I was completely out of the hatch with my body completely upside down on the ladder before I decided that it would be better if I turned over and went down feet first. Somehow I managed to swing my feet down and around without falling off the ladder. I think Andy was pretty much in the same predicament as I was.
Once we were on the ground, we hobbled into the electric shop and sat down. We told Bill Bennett that this was not a good solvent to use. I don’t even want to remember what the name of the solvent was. If I mentioned it, someone may put it in some tubs of white out and sell it to kids in Panama, because Trichloroethylene had nothing on this.
I suppose we finally found a replacement solvent. Though, I don’t remember what it was. All I do know is that it was quite an adventure trying to find one. Maybe we just used a lot of Electro contact cleaner after that.
Like Howard Chumbley, who told stories about being up to his elbows in transformer oil made with PCBs, I can now tell my fellow teammates at work, “Yeah. I remember the days when we were up to our elbows in Trichloroethylene. Never gave it a second thought.” Only, their reaction would be a little different than ours were in the electric shop office. They might raise their eyes up from their computer monitors and look across the cubicle at me for a moment. Then give me a look like “there goes that crazy old guy that used to work in a power plant again. Hasn’t he told us that story about 50 times already?” Well…. That solvent and stuff. It makes you forget things…. I can’t remember what I have already said.

When I was in my early 20’s my company shipped me up north to a different branch office and so began eight years of living in contractors guest house accommodation in a run down once-holiday-resort town. For about a year we had eight guys who were working on a local power station stay at the guest house, they were “lagging strippers” which wasn’t some night club job for brazen hussy’s but a job where the power station authorities had recognised that the asbestos that clad every single inch of their pipework was dangerous enough to get rid of, but not so dangerous that it had yet been legislated against when treating or handling the stuff (this was 1978/1980-ish).
The team of eight spent several years travelling the UK chipping off asbestos cement by hand wearing nothing more complicated that a thin paper face mask over their nose and mouth, their work clothing was jeans and tee shirt because as you’ll know, the inside of a power station can be warm work.
Their rate of pay was at least four times what our “normal” contracting electricians were being paid and our electricians were craftsmen and so on what was considered a “good wage”, the asbestos guys accepted with a shrug of the shoulders that theirs was a dangerous job, it was known that asbestos was dangerous but ther was no H&S law to protect them and so they took the money and hoped they wouldn’t die young – I have no doubt at all that most of them will be dead now as they used to come back to the guest house covered in white dust on the nights when they’d been in a hurry to leave site and not bothered getting changed, hell they probably exposed me to lots of asbestos dust too.
On one public holiday weekend we’d all gone back to our home towns and returned after the break, except this time there were only seven of them, the other had been to his doctor for a chest infection and an x-ray had revealed a shadow on his lung, the atmosphere was pretty down that week as they all knew what it could be, he never returned to the job.
As a sign off let me add that theses guys were not stupid or fearless or uncaring about their own mortality, they all had wives and some had young children, but they were mainly unskilled and how much persuasion do you need when you are unskilled and unemployed other than to offer you four times the skilled man rates – I saw lots of our electricians take up the golden wage packets on the oil rigs during the 1970s UK rush for North Sea oil – now there was a dangerous occupation…

If that Trichloroethylene caused you to have some memory loss today, I can’t even begin to imagine what your memory was like before the exposure. I don’t know of anyone with a memory like yours! I mean – who else can remember the shoe size of his cub scout leader’s nephew’s neighbor?
I have a bottle of White-out in my desk today and use it regularly. I play an Eb Contra Bass Clarinet. Most of the music we play is not scored for my instrument so I’ll use Tuba, String Bass, Cello, Bassoon, etc. music (all in “C”) and transpose it to Eb. It takes a little White-out sometimes.
I love Saturday mornings!

I suppose we finally found a replacement solvent. Though, I don’t remember what it was. All I do know is that it was quite an adventure trying to find one. Maybe we just used a lot of Electro contact cleaner after that.
Like Howard Chumbley, who told stories about being up to his elbows in transformer oil made with PCBs, I can now tell my fellow teammates at work, “Yeah. I remember the days when we were up to our elbows in Trichloroethylene. Never gave it a second thought.” Only, their reaction would be a little different than ours were in the electric shop office. They might raise their eyes up from their computer monitors and look across the cubicle at me for a moment. Then give me a look like “there goes that crazy guy that used to work in a power plant again. Hasn’t he told us that story about 50 times already?” Well…. That solvent and stuff. It makes you forget things…. I can’t remember what I have already said.
Comments from the original Post:

When I was in my early 20’s my company shipped me up north to a different branch office and so began eight years of living in contractors guest house accommodation in a run down once-holiday-resort town. For about a year we had eight guys who were working on a local power station stay at the guest house, they were “lagging strippers” which wasn’t some night club job for brazen hussy’s but a job where the power station authorities had recognised that the asbestos that clad every single inch of their pipework was dangerous enough to get rid of, but not so dangerous that it had yet been legislated against when treating or handling the stuff (this was 1978/1980-ish).
The team of eight spent several years travelling the UK chipping off asbestos cement by hand wearing nothing more complicated that a thin paper face mask over their nose and mouth, their work clothing was jeans and tee shirt because as you’ll know, the inside of a power station can be warm work.
Their rate of pay was at least four times what our “normal” contracting electricians were being paid and our electricians were craftsmen and so on what was considered a “good wage”, the asbestos guys accepted with a shrug of the shoulders that theirs was a dangerous job, it was known that asbestos was dangerous but ther was no H&S law to protect them and so they took the money and hoped they wouldn’t die young – I have no doubt at all that most of them will be dead now as they used to come back to the guest house covered in white dust on the nights when they’d been in a hurry to leave site and not bothered getting changed, hell they probably exposed me to lots of asbestos dust too.
On one public holiday weekend we’d all gone back to our home towns and returned after the break, except this time there were only seven of them, the other had been to his doctor for a chest infection and an x-ray had revealed a shadow on his lung, the atmosphere was pretty down that week as they all knew what it could be, he never returned to the job.
As a sign off let me add that theses guys were not stupid or fearless or uncaring about their own mortality, they all had wives and some had young children, but they were mainly unskilled and how much persuasion do you need when you are unskilled and unemployed other than to offer you four times the skilled man rates – I saw lots of our electricians take up the golden wage packets on the oil rigs during the 1970s UK rush for North Sea oil – now there was a dangerous occupation…

If that Trichloroethylene caused you to have some memory loss today, I can’t even begin to imagine what your memory was like before the exposure. I don’t know of anyone with a memory like yours! I mean – who else can remember the shoe size of his cub scout leader’s nephew’s neighbor?
I have a bottle of White-out in my desk today and use it regularly. I play an Eb Contra Bass Clarinet. Most of the music we play is not scored for my instrument so I’ll use Tuba, String Bass, Cello, Bassoon, etc. music (all in “C”) and transpose it to Eb. It takes a little White-out sometimes.
I love Saturday mornings!
Blowing it with Power Plant Retracts and Wall Blowers

(All right… right off the bat…. a run-on sentence the size of a paragraph… I can tell it’s going to be a long night).
To learn more about the dynamiters and shaking boiler tubes you can read the post: Cracking a boiled Egg in the Boiler. At other times while I was on the labor crew, I had heard these same benches making a tremendous sound that you could hear from a few landings away. It sounded like a large steam leak would sound, and at the same time, you could hear some kind of mechanical gears or something running and maybe a chain clanging. I didn’t really understand what the purpose of these long benches served then, only that it was a good place to put the water jug and the box of fly ash suits to keep them from being stepped on.
It was after I had become an electrician that these long metal benches took on another meaning. I found out that they were called “Retracts”. I was told that they called them retracts because what they do is they run a long metal pipe into the boiler and then Retract it back. Ok. I thought it was rather odd to name something for a seemingly insignificant part of the function. After I understood what they were used for, I thought I could come up with a lot better name than “Retract”.
After all, we had equipment like “Honey Wagon” , “Coffin Houses”, “Clinker Grinder”. All really descriptive names. So, when Charles Foster told me to go with Diane Lucas (later Diane Brien) to work on 7R retract, I was expecting to go find some little lever going back and forth making a sound like “brrrr…oops…..brrr…..oops” as it swung back and forth. I would name something like that a “Retract”.
Actually, I would like to have been able to have kept a couple of Retracts in my pocket so that when I would smart off to Leroy Godfrey our Electrical Supervisor, I could pull one out and press the button and… “swoop”! Retracted!
So, what is a Retract? Well. In the story that I linked to above about the cracked egg in the boiler, I explained how when I was on the labor crew we had to go in the boiler and tie ropes to these hanging boiler tubes and then shake them back and forth to clean out the hard ash that had built up on them. Well, The Retract would sort of do that when the boiler was online. They would clean out the tubes in the reheat area of the boiler for the most part.
Diagram of a boiler
What it would do is this. It seemed like 7R retract was about 40 feet long (someone at the plant can correct me if I’m wrong about the length). When it would turn on, it would start rotating a pipe about that long and start pushing it into the boiler. Once the nozzle at the end of the pipe was in the boiler a couple of feet steam would start blasting down the pipe to the nozzle on the end that would shoot the steam out at right angles to the pipe. As the pipe rotated, it would be shooting out steam in a circular motion as the pipe slowly traversed into the boiler.
You see… My dentist told me a long time ago that I should Floss my teeth more if I didn’t want to wear dentures when I was older. By keeping the bits of food out from between my teeth, not only did my breath smell better, but my gums could remain healthy as well. So, I listened to him and started flossing. Retracts are kind of like that.
The Retracts were designed to clean out the areas of the boiler where the ash would build up the most causing the efficiency of the boiler to be degraded. So at certain times of the day, the Control Room operator will push a button on the side panel (at least that was what they used to do… now they probably click an icon on their computer) and it would start the cycle of the retracts going in and out one at a time cleaning out the boiler.
This is a drawing of a Steam retract for a boiler. I added the Chinese characters in the drawing for my Asian readers… no, not really. Sorry the picture is a little small
Anyway. I finally learned what those long metal benches were for and it fascinated me. I wonder how long it took before someone said what now would seem obvious…. “Hey. Instead of having to bring the boiler offline every week or so, how about if we just create this boiler flossing equipment that cleans the boiler out while it is online?”
It made me wonder about the other equipment around the plant. I’ll bet there was a good use for just about everything. And you know what? I think I was right. Instead of just putting all that equipment all over the place for us to play on like a big jungle gym, everything seemed to have a real good purpose.
After 4 years working as a summer help, and one more year as a janitor and on the labor crew, I thought I had seen just about everything in the plant. When I became an electrician, all of the sudden a whole new world opened up to me. Even that bench I had been sitting on turned into a monster machine that blasted away ash clinkers while the rest of us lay at home in our beds dreaming of chocolate, and dragons, and um… other things people dream about.
So, what about the Wall Blower? Well. These are like the retracts, only they are much smaller. they were placed around the walls of the main boiler at strategic locations to blast clinkers that may be building up along the main wall of the boiler. The area in the boiler diagram up above called the Water Wall.
For some reason (and I’m sure it’s a good one), From what was called floor 6 1/2, though it was actually about the 13th floor, on down was an area called the “Boiler Enclosure”. This meant that when you walked up to the boiler, you first had to go through a door and enter an enclosed area around the boiler. 7th floor and above, the boiler was outside.
I’ve been to plants where the entire boiler was enclosed, and I’ve seen some that didn’t look like any of it was enclosed, so I figure this was a happy median between the two. It meant that if it was raining outside and you needed to work on the boiler, it made a big difference how high up you had to go as to whether you needed your rain suit or not.
I mention this because one day I had to go by myself to work on a wall blower that was on the 6 and 1/2 floor just at the top of the boiler enclosure. The wall blower was naturally situated right next to the boiler. and all the heat generated from the boiler and the piping that came from the bowl mills that blew the coal into the furnace had made the area very hot. The Wall blower had been tripping the breaker and I was supposed to go fix it.
I brought an infrared temperature gun with me and found that the area where the wall blower was mounted was 160 degrees. Maybe it was that high because it was the middle of a hot summer day, and with everything else going on, all the heat trapped right at the top of the boiler enclosure, it had just turned into a huge easy-bake oven.
When I touched the metal door to the control panel on the side of the wall blower, it burned my fingers. I had to use my tee-shirt as a rag to keep from burning my self. I could only stand next to the wall blower for about 30 seconds and then I had to walk back over the doorway and breathe some fresh air and cool off for a minute before going back.
After opening the control panel, I could see what the problem was right away. The insulation on the wires going to the terminal block had the insulation dripping off the wires. The insulation was melting.
I went back to the shop and found some wire that was designed for high temperatures, because obviously someone had used the wrong type of wire when assembling this particular wall blower, given it’s location on the boiler.
High Temperature Wire
Because of the intense heat where I was standing when trying to rewire the wall blower, I was not able to take very big breaths. I had to breathe very shallow, or not at all. So, I would go up to the blower and work as fast as I could removing a screw or putting a new wire down and then I would go back to the doorway about 60 feet from the wall blower and cool off.
As I mentioned in the post about the Luxuries and Amenities of a Power Plant Labor Crew, when you are in this intense heat, your hardhat becomes soft like a baseball cap. In this case, I wasn’t in the heat long enough for this to happen, though I was sweating like a pig.
I had been doing this for a while when an operator showed up wondering what I was doing. His name was Jim Waller and he had been watching me from a distance. He said he was trying to figure out what I was up to because he would see me show up at the doorway and stand there for a while not doing anything, then turning around like I had forgotten something only to show up again about 1/2 minute later.
When he couldn’t figure out what I was doing on his own, he decided to take a closer look. I found him standing at the doorway waiting for me to arrive with a puzzled look on his face. I was tempted to just say nothing and just stand there and take a few breathes and then go back to the wall blower and continue my work.
I couldn’t do that however, when Jim asked me what I was doing. Jim was one of the nicest and most normal operators you could run across. I just couldn’t joke with him. So, I told him I was working on that wall blower over there, but that it was so hot that I had to keep coming to the doorway to cool off.
Jim Waller had come to work for the electric company a month before I began my last summer as summer help in 1982. At the time that I was working on the wall blower in 1984 I was just about to become 24 years old, and a couple of months later, he was going to be 29. Like Gene Day, you instantly knew when you saw Jim that he you liked him. He sort of had that Jim Nabors kind of smile.
Jim Waller reminded me of Jim Nabors when he was younger. He had the same likable demeanor.
Unlike Gene Day, I never felt like playing a joke on Jim. For some reason, Jim just seemed like too nice of a guy. Where Gene had a slight sort of hidden orneriness about him, Jim was just purely a “good guy”.
This past Christmas eve, five days before Jim turned 57 years old, he passed away after a sudden illness. When the guys at the power plant told me about it, I was sad for their loss and for his family. For Jim, on the other hand…. I think he has always had one foot in heaven from the day I met him. I think he finally stepped the rest of the way through the gate.
For someone like me. If I am ever able to make it to heaven, I’m sure there will be a big to-do about it, because someone would have won the pot and I’m sure the odds would have been high against it. However, the day Jim arrived, it was probably more like “business as usual”. — “Oh, Jim’s arrived….. Like no one didn’t see that coming….” If I could say something to Jim now (and being Catholic, I’m allowed to do that), I would ask Jim, “Put in a good word for all the Power Plant Men!” Because I know that Jim’s word is as good as gold. Here is a real picture of Jim, a true Power Plant Man:
Jim Waller, a True Power Plant Man!

Good post on Jim, Kevin. Now, what is a “normal operator”? 🙂
I remember doing several jobs in super hot areas where I had to wear a heavy coat and gloves to keep from getting burned. Had to take off rings and wrist watch too. Needed to take off my glasses, but then I couldn’t see.

Good post on Jim, Kevin. Now, what is a “normal operator”? 🙂
I remember doing several jobs in super hot areas where I had to wear a heavy coat and gloves to keep from getting burned. Had to take off rings and wrist watch too. Needed to take off my glasses, but then I couldn’t see.
Solving the Selection of a Power Plant Solvent
A year after I joined the electricians in the electric shop, Howard Chumbley became my foreman. One day when we were talking about going to the old Osage Plant up the road to clean up a PCB (Polychlorinated Biphenyls) spill, he explained that “In His Day” they used to clean their tools in a vat of transformer oil that was full of PCBs. I remember him telling us that it was normal for him to be up to his elbows in the stuff. They never thought it might be harmful. Now we were getting ready to go up to the old plant to clean up a small spill and I was going to have to suit up in a special hazardous waste suit. I wrote about our experience in the post: “Pioneers of Power Plant Fame Finally Find Rest“.
Now we know about the hazard of developing cancer by having PCBs in your system. Today we know a lot of things we didn’t know back then. We know that Asbestos causes Mesothelioma. We know that Chlorofluorocarbons (CFC) destroy the ozone layer. We know that Twinkies are one of the few foods that will be around after a nuclear holocaust.
Years before I became an electrician, the Electric Company had stopped using oil with PCBs. There was still an effort to clean it up from the older plants. At the new coal-fired power plant in north central Oklahoma, we didn’t have a problem with PCBs. We had other problems. Some of which we didn’t know about (well, we knew something, just not so much) at the time.
A very prominent responsibility of mechanics and electricians was to clean oily equipment. Pumps and motors, breakers, fans, mills. All kinds of equipment. Almost everything was lubricated one way or another with oil. Solvent was used to remove the oil when the equipment needed to be cleaned.
We had a standard kind of solvent at our plant. I believe it was called “Standard Solvent 350”. See…. It was a Standard solvent. Even had the word Standard in the name. One of the key ingredients of this standard solvent is a solvent known as “Stoddard Solvent”. This solvent worked real good when cleaning up equipment like motors and pumps and other oily equipment. Many times we were “Up to our elbows” in this solvent.
We had a barrel in the corner of the electric shop close to the door to the main switchgear where we could put a motor and scrub it clean while solvent poured out of a flexible nozzle on the motor, your shirt, your pants, your work boots, and the floor. Some days during overhauls when we would work cleaning motors for 10 hours each day, I would come home from work drenched in solvent. My wife would make me take my clothes off in the utility room where I could put them directly into the washing machine where Oxydol could go to work on it right away.
When Ted Riddle and I were working for Willard Stark on an overhaul at the gas plant outside Mustang Oklahoma during the spring of 1986, Willard said one day that he wanted to show us something. I explained Willard’s situation at the plant in a post called “Working Power Plant Wonders with Willard Stark“.
He was a good example of what I would call a “Contrarian.” That is, he seemed to buck the system often. He thought outside the box a lot. I realized this right way when we would listen to Paul Harvey on the radio during lunch. Every time Paul Harvey would say, “…Noon News and Comment” Willard would always finish the sentence by saying, “Mostly Comment.” I figured then that he had to be a contrarian, because who would ever think that Paul Harvey wasn’t the best person in the world to bring the News to our private little power plant world.
Paul Harvey was one of a kind radio personality. No one will ever fill his shoes.
So, when Willard said he was wanted us to see something “with our own eyes”, I figured this was going to be something good. Probably some kind of secret place where you could hide and take a nap if the day wore on too long, or something like that. Well… It didn’t turn out to be that kind of “something”, but it was something.
Willard took a small metal pan and put some Stoddard Solvent in it. The old gas plant used straight Stoddard Solvent, unlike the more sophisticated Coal-fired plant where Ted Riddle and I normally worked. We walked out into the turbine-generator (T-G) floor. He placed the pan of solvent on the floor, took a WypAll (which is a strong paper rag) and dropped it into the pan:
A package of an Important Power Plant Staple: WypAlls!
Then he bent down and with his lighter, he lit the WypAll on fire. We watched as the flames grew higher and higher. Willard watched our expressions. We had been under the understanding that Solvent was not flammable. He explained that technically, Stoddard Solvent is not considered “Flammable”, but it is considered “Combustible”. Combustible means that it burns.
A bucket of Stoddard Solvent. Notice this bucket clearly says “Combustible”
Stoddard Solvent doesn’t ignite fast enough to be considered “Flammable”. At least that’s the way Willard explained it to us. Willard said he wanted us to be aware of this fact when we have our bodies all soaked in solvent, that if we were to catch on fire for some reason, we were going to go up in flames just like that WypAll. We both appreciated the advice.
I didn’t begin this post expecting to say that much about Stoddard Solvent, but just in case you were really wondering what it is, maybe this picture will explain it to you:
A Chemist-eye view of Stoddard Solvent
I hope that cleared it up for you.
The solvent I really wanted to talk about was one that was used more exclusively in the electric shop. It is called Trichloroethylene 1.1.1. You see, a lot of equipment that we cleaned in the electric shop needed to be cleaned spotless. Solvent 350 would leave a film when it dried. So, in the electric shop when we needed to clean something with electric contacts we would use something called “Electro Contact Cleaner”:
Spray Can of LPS Electro Contact Cleaner – Only the cans we used didn’t say CFC Free
This was very expensive compared to the regular solvent. So, I was surprised when Ben Davis and I first went on an overhaul in Muskogee, and they had this exact same contact cleaner in 55 gallon barrels:
Barrel of LPS Electro Contact Cleaner
I remember John Manning showing us a few of these barrels that they had ordered for the overhaul. I think my jaw dropped. By my calculation, one barrel like this would cost over $3,000.00. I figured if it was in cans, it would have cost three times that amount. The advantage of using Contact cleaner was that it dried clean. It didn’t leave a residue.
Trichloroethylene 1.1.1 was like that. It didn’t leave a residue when it dried. I think this will become obvious to you when you see what it really is:
Chemical Composition of Trichoroethylene
You can see right off the bat that this is going to dry clean… I mean…. it’s obvious… right?
Anyway. This stuff evaporated quickly so when you were up to your elbows in this solvent, it felt cool because it would evaporate causing a cooling effect. It had a very peculiar smell. It also made you feel a little dizzy when you were using it. Especially when you had to breathe in a lot of in a confined area. Having fans blowing on you seemed to make it worse, because it would increase the evaporation rate filling the air with more solvent.
It was known at the time that Trichloroethylene would destroy your liver when it gets into your blood stream. There was no quicker way of injecting the solvent into your blood stream than by inhaling it. Finally OSHA decided that this solvent was no longer safe to be used in a plant setting. It could only be used in small quantities like “White Out”.
Gee… Who remembers White Out?
A bottle of White Out. Oh look. A New Formula!
The last time I heard about white out was in a blonde joke about someone using white out on the computer monitor. Who types anymore on a typewriter? I think anyone today that would choose to type on a typewriter would be the type of person that would prefer a typewriter eraser over white out.
I take that back. The last time I heard about White Out was on a show like 60 Minutes where they were showing young kids in Panama or another Central American country being hooked on tubs of White Out. They would sit around all day taking quick whiffs from a tub of White Out. — Why? Because it contained Trichloroethylene and it would give you a buzz.
My dad, a Veterinary professor at Oklahoma State University had told me about the dangers of Trichloroethylene around the time I told him about Bill McAlister using WD-40 on his elbows to ease the pain of his arthritis. Sonny Karcher had asked me to talk to my dad about it to see if he knew why WD-40 would help Arthritis.
My father (I’ll call him Father in this paragraph, because in this paragraph, he’s being more “sophisticated”) told me that WD-40 had the same chemical in it that Veterinarians used on horses to help their joints when they hurt. Then he warned me that the solvent in WD-40 soaks right into your skin and when it does it carries other toxic chemicals into your body than just the arthritis lineament. So, he told me to tell Sonny not to use it often.

So, anyway, we had to find a replacement for Trichloroethylene. Tom Gibson and Bill Bennett went to work ordering samples of other kinds of solvents that salesmen were saying would be a good replacement. One of the first that we tried was called Orange Solvent. It had a real nice Orange smell. Sort of like drinking Tang.

It had a couple of problems. First, I would be more inclined to drink it since it smelled so good, and I was a fan of Tang at the time.

The second problem with the Orange Solvent was that it didn’t seem to clean very well. We were used to something cutting the oil and contact grease quickly. the Orange Solvent didn’t cut the mustard (so to speak).
One day during overhaul at our plant, Bill Bennett gave us a barrel of some new kind of solvent. It was supposed to be comparable in it’s cleaning ability to Trichloroethylene (could you imagine Red Skelton trying to say that word?)
Red Skelton saying “Trichloroethylene”
Bill wanted Andy Tubbs and I to use the new solvent on the main power transformer main bus connectors. They are normally covered with No-Ox Grease so this would be a good test.
A jar of No-Ox Grease (No-Ox means No Oxide)
So, Andy and I carried the large extension ladder out to the Unit 1 Main Power Transformer and leaned it up against the back side. We climbed up to the open hatchways and climbed in. We hung a small yellow blower in the doorway to blow fresh air on us.
A Main Power Transformer
Andy and I had everything setup and we were ready to work. We both just fit in the small area with the large bus work between us. We began using our rags soaked in the new solvent on the silver plated bus. I don’t remember how well the solvent cleaned the bus. I just remember thinking that this solvent sure did evaporate quickly. Especially with the blower fan right next to us.
I also remember looking over at Andy crouched across from me. He was looking down at the bus. Then his entire body seemed to swivel around as if he was on some kind of swing which caused him to tilt up the side of the enclosure. I watched his face, and he seemed to be saying something to me, only I couldn’t make it out.
I think I said something like “Huh?” Then about that time all kinds of brightly lit flowers were circling around my head and my arms seemed to be floating in front of me. I heard Andy say with a slur, “We better get out of here…” His voice sounded like it was in a pipe…. Well, we sort of were sitting in a pipe… He started to move toward the hatchway.
I remember briefly thinking that I was just fine enjoying the interesting scenery. By now there were bright lights streaming toward me from all sides. Then I thought. “No. I better leave.” So, I struggled to pull myself into the hatchway. It was big enough that we could both pull ourselves out together.
I began climbing down the ladder head first. It was about 15 feet to the ground. I was completely out of the hatch with my body completely upside down on the ladder before I decided that it would be better if I turned over and went down feet first. Somehow I managed to swing my feet down and around without falling off the ladder. I think Andy was pretty much in the same predicament as I was.
Once we were on the ground, we hobbled into the electric shop and sat down. We told Bill Bennett that this was not a good solvent to use. I don’t even want to remember what the name of the solvent was. If I mentioned it, someone may put it in some tubs of white out and sell it to kids in Panama, because Trichloroethylene had nothing on this.
I suppose we finally found a replacement solvent. Though, I don’t remember what it was. All I do know is that it was quite an adventure trying to find one. Maybe we just used a lot of Electro contact cleaner after that.
Like Howard Chumbley, who told stories about being up to his elbows in transformer oil made with PCBs, I can now tell my fellow teammates at work, “Yeah. I remember the days when we were up to our elbows in Trichloroethylene. Never gave it a second thought.” Only, their reaction would be a little different than ours were in the electric shop office. They might raise their eyes up from their computer monitors and look across the cubicle at me for a moment. Then give me a look like “there goes that crazy guy that used to work in a power plant again. Hasn’t he told us that story about 50 times already?” Well…. That solvent and stuff. It makes you forget things…. I can’t remember what I have already said.
Power Plant Retracts and Wall Blowers Enough to Blow your Mind
I never gave it much thought that when I was on the labor crew at the Coal-fired Power Plant in Oklahoma and we had to go in the boiler to shake the boiler tubes, that next to the portals where you would climb into the boiler there were long metal benches where you could sit just outside while you rested between moments when the dynamiters were getting ready to set off their explosives. (All right… right off the bat…. a run-on sentence the size of a paragraph… I can tell it’s going to be a long night).
To learn more about the dynamiters and shaking boiler tubes you can read the post: Cracking a boiled Egg in the Boiler. At other times while I was on the labor crew, I had heard these same benches making a tremendous sound that you could hear from a few landings away. It sounded like a large steam leak would sound, and at the same time, you could hear some kind of mechanical gears or something running and maybe a chain clanging. I didn’t really understand what the purpose of these long benches served then, only that it was a good place to put the water jug and the box of fly ash suits to keep them from being stepped on.
It was after I had become an electrician that these long metal benches took on another meaning. I found out that they were called “Retracts”. I was told that they called them retracts because what they do is they run a long metal pipe into the boiler and then Retract it back. Ok. I thought it was rather odd to name something for a seemingly insignificant part of the function. After I understood what they were used for, I thought I could come up with a lot better name than “Retract”.
After all, we had equipment like “Honey Wagon” , “Coffin Houses”, “Clinker Grinder”. All really descriptive names. So, when Charles Foster told me to go with Diane Lucas (later Diane Brien) to work on 7R retract, I was expecting to go find some little lever going back and forth making a sound like “brrrr…oops…..brrr…..oops” as it swung back and forth. I would name something like that a “Retract”.
Actually, I would like to have been able to have kept a couple of Retracts in my pocket so that when I would smart off to Leroy Godfrey our Electrical Supervisor, I could pull one out and press the button and… “swoop”! Retracted!
So, what is a Retract? Well. In the story that I linked to above about the cracked egg in the boiler, I explained how when I was on the labor crew we had to go in the boiler and tie ropes to these hanging boiler tubes and then shake them back and forth to clean out the hard ash that had built up on them. Well, The Retract would sort of do that when the boiler was online. They would clean out the tubes in the reheat area of the boiler for the most part.

What it would do is this. It seemed like 7R retract was about 40 feet long (someone at the plant can correct me if I’m wrong about the length). When it would turn on, it would start rotating a pipe about that long and start pushing it into the boiler. Once the nozzle at the end of the pipe was in the boiler a couple of feet steam would start blasting down the pipe to the nozzle on the end that would shoot the steam out at right angles to the pipe. As the pipe rotated, it would be shooting out steam in a circular motion as the pipe slowly traversed into the boiler.
You see… My dentist told me a long time ago that I should Floss my teeth more if I didn’t want to wear dentures when I was older. By keeping the bits of food out from between my teeth, not only did my breath smell better, but my gums could remain healthy as well. So, I listened to him and started flossing. Retracts are kind of like that.
The Retracts were designed to clean out the areas of the boiler where the ash would build up the most causing the efficiency of the boiler to be degraded. So at certain times of the day, the Control Room operator will push a button on the side panel (at least that was what they used to do… now they probably click an icon on their computer) and it would start the cycle of the retracts going in and out one at a time cleaning out the boiler.
This is a drawing of a Steam retract for a boiler. I added the Chinese characters in the drawing for my Asian readers… no, not really. Sorry the picture is a little small
Anyway. I finally learned what those long metal benches were for and it fascinated me. I wonder how long it took before someone said what now would seem obvious…. “Hey. Instead of having to bring the boiler offline every week or so, how about if we just create this boiler flossing equipment that cleans the boiler out while it is online?”
It made me wonder about the other equipment around the plant. I’ll bet there was a good use for just about everything. And you know what? I think I was right. Instead of just putting all that equipment all over the place for us to play on like a big jungle gym, everything seemed to have a real good purpose.
After 4 years working as a summer help, and one more year as a janitor and on the labor crew, I thought I had seen just about everything in the plant. When I became an electrician, all of the sudden a whole new world opened up to me. Even that bench I had been sitting on turned into a monster machine that blasted away ash clinkers while the rest of us lay at home in our beds dreaming of chocolate, and dragons, and um… other things people dream about.
So, what about the Wall Blower? Well. These are like the retracts, only they are much smaller. they were placed around the walls of the main boiler at strategic locations to blast clinkers that may be building up along the main wall of the boiler. The area in the boiler diagram up above called the Water Wall.
For some reason (and I’m sure it’s a good one), From what was called floor 6 1/2, though it was actually about the 13th floor, on down was an area called the “Boiler Enclosure”. This meant that when you walked up to the boiler, you first had to go through a door and enter an enclosed area around the boiler. 7th floor and above, the boiler was outside.
I’ve been to plants where the entire boiler was enclosed, and I’ve seen some that didn’t look like any of it was enclosed, so I figure this was a happy median between the two. It meant that if it was raining outside and you needed to work on the boiler, it made a big difference how high up you had to go as to whether you needed your rain suit or not.
I mention this because one day I had to go by myself to work on a wall blower that was on the 6 and 1/2 floor just at the top of the boiler enclosure. The wall blower was naturally situated right next to the boiler. and all the heat generated from the boiler and the piping that came from the bowl mills that blew the coal into the furnace had made the area very hot. The Wall blower had been tripping the breaker and I was supposed to go fix it.
I brought an infrared temperature gun with me and found that the area where the wall blower was mounted was 160 degrees. Maybe it was that high because it was the middle of a hot summer day, and with everything else going on, all the heat trapped right at the top of the boiler enclosure, it had just turned into a huge easy-bake oven.
When I touched the metal door to the control panel on the side of the wall blower, it burned my fingers. I had to use my tee-shirt as a rag to keep from burning my self. I could only stand next to the wall blower for about 30 seconds and then I had to walk back over the doorway and breathe some fresh air and cool off for a minute before going back.
After opening the control panel, I could see what the problem was right away. The insulation on the wires going to the terminal block had the insulation dripping off the wires. The insulation was melting.
I went back to the shop and found some wire that was designed for high temperatures, because obviously someone had used the wrong type of wire when assembling this particular wall blower, given it’s location on the boiler.
High Temperature Wire
Because of the intense heat where I was standing when trying to rewire the wall blower, I was not able to take very big breaths. I had to breathe very shallow, or not at all. So, I would go up to the blower and work as fast as I could removing a screw or putting a new wire down and then I would go back to the doorway about 60 feet from the wall blower and cool off.
As I mentioned in the post about the Luxuries and Amenities of a Power Plant Labor Crew, when you are in this intense heat, your hardhat becomes soft like a baseball cap. In this case, I wasn’t in the heat long enough for this to happen, though I was sweating like a pig.
I had been doing this for a while when an operator showed up wondering what I was doing. His name was Jim Waller and he had been watching me from a distance. He said he was trying to figure out what I was up to because he would see me show up at the doorway and stand there for a while not doing anything, then turning around like I had forgotten something only to show up again about 1/2 minute later.
When he couldn’t figure out what I was doing on his own, he decided to take a closer look. I found him standing at the doorway waiting for me to arrive with a puzzled look on his face. I was tempted to just say nothing and just stand there and take a few breathes and then go back to the wall blower and continue my work.
I couldn’t do that however, when Jim asked me what I was doing. Jim was one of the nicest and most normal operators you could run across. I just couldn’t joke with him. So, I told him I was working on that wall blower over there, but that it was so hot that I had to keep coming to the doorway to cool off.
Jim Waller had come to work for the electric company a month before I began my last summer as summer help in 1982. At the time that I was working on the wall blower in 1984 I was just about to become 24 years old, and a couple of months later, he was going to be 29. Like Gene Day, you instantly knew when you saw Jim that he you liked him. He sort of had that Jim Nabors kind of smile.
Jim Waller reminded me of Jim Nabors when he was younger. He had the same likable demeanor.
Unlike Gene Day, I never felt like playing a joke on Jim. For some reason, Jim just seemed like too nice of a guy. Where Gene had a slight sort of hidden orneriness about him, Jim was just purely a “good guy”.
This past Christmas eve, five days before Jim turned 57 years old, he passed away after a sudden illness. When the guys at the power plant told me about it, I was sad for their loss and for his family. For Jim, on the other hand…. I think he has always had one foot in heaven from the day I met him. I think he finally stepped the rest of the way through the gate.
For someone like me. If I am ever able to make it to heaven, I’m sure there will be a big to-do about it, because someone would have won the pot and I’m sure the odds would have been high against it. However, the day Jim arrived, it was probably more like “business as usual”. — “Oh, Jim’s arrived….. Like no one didn’t see that coming….” If I could say something to Jim now (and being Catholic, I’m allowed to do that), I would ask Jim, “Put in a good word for all the Power Plant Men!” Because I know that Jim’s word is as good as gold. Here is a real picture of Jim, a true Power Plant Man:
Jim Waller, a True Power Plant Man!
Power Plant Men 
When I was in my early 20’s my company shipped me up north to a different branch office and so began eight years of living in contractors guest house accommodation in a run down once-holiday-resort town. For about a year we had eight guys who were working on a local power station stay at the guest house, they were “lagging strippers” which wasn’t some night club job for brazen hussy’s but a job where the power station authorities had recognized that the asbestos that clad every single inch of their pipework was dangerous enough to get rid of, but not so dangerous that it had yet been legislated against when treating or handling the stuff (this was 1978/1980-ish).
The team of eight spent several years travelling the UK chipping off asbestos cement by hand wearing nothing more complicated that a thin paper face mask over their nose and mouth, their work clothing was jeans and tee shirt because as you’ll know, the inside of a power station can be warm work.
Their rate of pay was at least four times what our “normal” contracting electricians were being paid and our electricians were craftsmen and so on what was considered a “good wage”, the asbestos guys accepted with a shrug of the shoulders that theirs was a dangerous job, it was known that asbestos was dangerous but there was no H&S law to protect them and so they took the money and hoped they wouldn’t die young – I have no doubt at all that most of them will be dead now as they used to come back to the guest house covered in white dust on the nights when they’d been in a hurry to leave site and not bothered getting changed, hell they probably exposed me to lots of asbestos dust too.
On one public holiday weekend we’d all gone back to our home towns and returned after the break, except this time there were only seven of them, the other had been to his doctor for a chest infection and an x-ray had revealed a shadow on his lung, the atmosphere was pretty down that week as they all knew what it could be, he never returned to the job.
As a sign off let me add that theses guys were not stupid or fearless or uncaring about their own mortality, they all had wives and some had young children, but they were mainly unskilled and how much persuasion do you need when you are unskilled and unemployed other than to offer you four times the skilled man rates – I saw lots of our electricians take up the golden wage packets on the oil rigs during the 1970s UK rush for North Sea oil – now there was a dangerous occupation…
