Placed on Light Duty at the Power Plant

Originally posted July 19, 2013:

In another profession being put on light duty may mean that you don’t have to work as hard as everyone else.  When an electrician is put on light duty it means something else entirely.  I think I calculated the number of lights and it was well over 10,000 light bulbs in the coal-fired power plant in North Central Oklahoma.  Ideally you would think that every one of the lights should be in good working order.

Electricians don’t call a light bulb a light.  The light is the fixture.  The bulb is called a “lamp”.  So, for the rest of this post I’ll call the light bulbs “lamps”.

You may think that it’s pretty straight forward to go change out lights (oh.  I mean… lamps), but it’s not.  You see, it isn’t like in your house where you have the regular light bulbs everywhere with just different shapes and wattage.  Sure, there were different Watts for the different lamps, but for a good number of the lights, they varied by voltage as well.

Not only that, but these lamps were different types of lights.  Most of which are not incandescent (well… now that the government has seen fit to force the lighting industry to stop making incandescent lamps altogether, I guess it wouldn’t seem odd to the younger folks).

In the office areas and places like the main switchgear 4 foot fluorescent lamps were used.  Each 4 foot fluorescent lamp is 40 watts.  Just because it is 40 watts, it doesn’t mean that the voltage is low.  It can take up to 650 volts to start up a fluorescent lamp.  A Fluorescent lamp actually has a gas in it that causes a coating on the glass to glow when a current flows across the gas.

Besides the typical fluorescent lamps, the majority of the rest of the lamps in the plant were various sizes of Mercury Vapor lamps.  (now replaced with Sodium Vapor).

Before you become all twisted about using Mercury Vapor to light up a power plant because of the environmental impact, I think I should point out that even though a fluorescent lamp is filled with an inert gas like argon, it is mixed with Mercury vapor as well, and the phosphorous coating on the glass has mercury in it also.

So, if you have fluorescent lamps in your house…. Well, there you go.  And you know those lamps that are used to replace your old incandescent light bulbs….. Yep… and they have other kinds of hazardous metals as well.  I suppose it is good for the environment to take those hazardous materials out of the earth and put them in lamps in your houses.  Isn’t that improving the environment?

The thing about using Fluorescent lamps and Mercury Vapors and Sodium Vapor lamps is that they all use different voltages.  So, in order for them to start up and stay running, the voltages have to change from the start up voltage to the operating voltage.  Each lamp has it’s own transformer designed just for that one type of lamp.  It is placed in the light fixture for the lamp.

You can tell this is a 100 Watt Mercury Vapor lamp because of the 10.  If it had a 25, then it would be a 250 watt lamp.   Following the same logic if it has a 75 on it, then it is a 75 watt lamp..... oh...well.. the logic is there somewhere

If the light glows blue, then it is mercury vapor.  If it is orange then it is a sodium light.  Your street lights are the same way.  Well.  Now there is also Halogen lamps which shine white.

Besides these different type lamps, we also had some super special lights.  We have the flashing lights on the smoke stack and the red blinking light on the top of the radio tower.  The lights that flash on the smoke stacks are really flashbulbs.

Our smoke stacks are 500 feet tall with beacons at the 250 foot level and the 500 foot level.  Not only did you have to change out the bulb, but you often had to change out the large capacitors and the circuit boards that had been fried by a passing lightning storm.

You may have heard that with the older style Television sets that had a picture tube (before the flat screen TVs came around), that you could electrocute yourself by taking the cover off the back of the TV and working on it, even though you unplugged the set from the wall before you started.  A few movies used this in the plot.  Robert T. Ironside even used it once in an episode during the first season.

Well.  The Stack lights are like that.  When we opened up the light fixture to work on the flash tube or the circuits inside the first thing you did was take a metal rod with a wooden handle and a wire attached with a clip on the end and clipped the wire to the handrail.  Then turning your head the other way, you placed the metal rod across each of the large capacitors in the box.   Invariably, one of the capacitors would let out a loud pop that would echo across the lake…. oh, and leave your ears ringing.

Once the voltage was discharged from all the capacitors, you knew it was safe to go to work fixing the light.  The lights had a day and a night mode, and the difference was how many times the flash tube flashed when it discharged.  What I mean to say is that it wasn’t just one flash.  It is really a series of flashes closely timed to look like one flash.  The number of flashes and the timing between the flashes determine how bright the flash is.

At night the flash was much dimmer because it didn’t need to be so bright.  When it was stuck in the day mode at night the farmers for a 30 mile radius would be calling saying they can’t sleep because every 6 seconds their bedroom would light up as the smoke stack lights would blink.

I thought I would just put that picture in there so you could see how pretty the plant looked from across the lake at sunset.  To me it looked like a big ship on the horizon.

I mentioned above that there was a radio tower that had a light on it that needed to be changed when it burned out.  The actual lamp looked a lot like a regular incandescent bulb in your house, but it was different.  It was designed just for this job.  It didn’t burn out very often.  Ok.  I can see your look of disbelief, so here is a picture of one:

Yeah, looks just like something in your house.  Doesn’t it?

Anyway.  I changed out the light at the top of our radio tower which is only about 200 feet tall.  It looked like the following picture:

Our tower was like this only it didn't have a safety pole up the side for a lanyard.

Our tower was like this only it didn’t have a safety pole up the side for a lanyard.

I had to climb to the top of this tower to replace the red flashing light.  I was by myself when I did it.  Bill Bennett handed me the bulb that had been specially ordered and asked me if I would do it.  If not, they could call Oklahoma City and have the line crew come down and change it.  I told him I could do it.  The tower wasn’t that tall, and I had shimmied around the top of the smoke stack before at 500 feet with only a slight urge to panic.

I changed the lamp out without incident.  I know that some people have a much more interesting job changing these lights out than I had.  Our radio tower was only 200 feet tall.  Here is a video of someone that had to climb a tower 1768 feet high.  You can see the beacon when they reach the top of this radio tower:

if your browser doesn’t play the video from the picture try this link:  “Climbing a 1768 foot tower“.

Ok.  That is crazy!  Wouldn’t dropping someone from a helicopter onto the tower using a safety line be safer?

My last story about being on light duty at a power plant is about when Ted Riddle and I were working at the gas-fired power plant near Mustang, Oklahoma.  I talked about the time that Ted and I worked at this plant in the post “Working Power Plant Wonders with Willard Stark

While we were there after they found out that we were electric conduit running fools, they gave us all sorts of jobs running conduit all over the plant.  One job they showed us was in an area that was dark.  All the lights were out in this area.  The foreman explained where the light bulbs were kept.  They were just the regular incandescent lights like the normal lights you would have in your house.

Well… Ted and I had both been put on Light Duty at our plant, and we knew that when we went to change out one light, we were supposed to change out all the lights that were out.  So, Ted and I each grabbed a box and a ladder and headed up to the boiler enclosure to change lights.

After lunch, the foreman came running up to us yelling, “What did you do?  You used up all of the light bulbs!”  Well.  Yes.  We had used up the lights, but now when you go up on the boiler you can see where you are going.  The foreman then explained to us  that this little plant didn’t have the same kind of budget that the new big plants had.  They couldn’t afford to just go around replacing all the lights whenever they burned out.  They only put in a light when someone has to work in that area.  We had lit the entire place up like a Christmas tree.

Ok.  Take a note Jan… Don’t replace all the lights if they are incandescent.

Ok (again), that wasn’t quite the last story.  Let me tell you some more about replacing Fluorescent lamps in our Coal-fired power plant.  When we were placed on Light Duty, we would grab a couple of boxes of 30 lamps from the pallet in the main switchgear and go to work.

In the main switchgear the lights were up high, so we used a 10 foot ladder with a stand on the top of it (No.  I don’t mean like a Deer stand…. geez… Power Plant men…. always thinkin’ ’bout huntin’).  Actually it is called a Platform ladder:

This is a 6 foot platform ladder.  Ours was 10 foot and very wobbly

This is a solid 6 foot platform ladder. Ours was 10 foot and very wobbly

I didn’t like using this wobbly ladder when I was by myself.  besides being wobbly, the thing weighed a ton.  So, I would take a smaller ladder and put it on top of the breaker cabinets and climb on top of them.  The only problem here was that I couldn’t get directly under the lights, so I would end up reaching out to one side to change a light while I was standing on a ladder on top of a seven foot cabinet.  Not a pretty sight if someone safety minded walked in.

I felt safer doing this than standing way up in the air on a 10 foot wobbly platform ladder.  I always had the feeling that if I sneezed, the ladder would topple over.  The rule of thumb was to keep your belt buckle within the rungs on the ladder.

When we were done changing out fluorescent lamps, we usually had a stack of boxes of burned out lamps.  We couldn’t just throw them in the dumpster because they were a safety hazard as they were.  We had to break each bulb.  We found that we could take a box of 4 foot fluorescent lamps and back the truck over it and it would let out a low but loud boom that sounded like a cannon going off.

The ingenious electricians invented a bulb busting barrel where you slid one 4 foot bulb into a tube and then lifted a handle quickly, and it would explode the lamp in the safe confines of the metal barrel.  The end of the lamp may at times come shooting out the end of the tube, so you never wanted to be standing to that side of the barrel.  I would show you a picture of one, but I’ve never found another one like it.

So, if you were into breaking glass, this was the best part of being placed on Light Duty.  After a hard day of changing out lamps all over the plant, you could stand around in front of the electric shop and slide the lamps down a tube like mortar shell and pull the rod and…. Boom! A puff of Mercury Vapor released into the atmosphere a small cloud of dust…. repeat.

    I remember being on “Light Duty” at the Mustang Power Plant as a summer student in 1967. We changed the 1000 watt bulbs in the top of the turbine room. It was so hot, we had to wear gloves.

Prolonged Power Plant Pause Before the Panic

Originally posted September 6, 2013:

Today when I attend meetings while on the job at Dell (and now at GM) and the discussion is about something new, and the manager is looking for input from the team, I usually sit there quietly while the others share their thoughts. This is not my usual behavior in other settings as I am usually quick to respond with a quip or something sarcastic.

Later, after everyone else has given their two cents, then if asked, I will wade in with both feet. This hasn’t always been the course of action I would have taken. Actually, I used to be pretty hot-headed. I was usually the first person to respond when someone asked a question. I already had my mind made up about just about everything.

My wife began noticing a change in my behavior a few years after we were married. She would ask me a simple question, like, “Would you like a piece of gum.” I would suddenly go into a momentary comatose state where I would stare off into space and think about it. She would say something like, “The answer doesn’t need a lot of thought. It is either ‘yes’ or ‘no’.”

After careful analysis, I finally figured out what happened. The transformation began the day I entered the electric shop at the coal-fired power plant as an electrician. I described that first day in the post “New Home in the Power Plant Electric Shop“. In that post I described my first job as an electrician when I went to the coalyard with my foreman Charles Foster to fix a room heater that wasn’t working.

The first time I used my new tools, Charles told me to remove a screw from a fuse block so that we could lift a wire in order to replace the fuse block.

A small fuse block like this.

When I was removing the wire (with one hand, as Charles had warned me that an electrician never uses two hands to do this), the screwdriver slipped and shorted out on the mounting screw which caused a brief flash. In the millisecond that the flash occurred, it cut a notch in the tip of my new Stanley screwdriver.

This was the beginning of my 18 year career of various minor electrocutions and small explosions. We did things to minimize the chances of shorting out your screwdriver when working on a hot circuit (that means a circuit that has the electricity still turned on). One thing we would do is wrap rubber tape up the metal shank so that if it leaned against something metal with it while the tip was touching something hot, it wouldn’t short out the circuit.

Inevitably, something would happen every now and then and something was going to explode. So you just had to be prepared for that. This is where the “Prolonged Pause” comes in.

Sometimes there is nothing you can do. Let me give you a “For Instance”. One time when we had an overhaul on Unit 1 (we had 2 units at our Power Plant in North Central Oklahoma), Richard Moravek was visiting from the Power Plant in Muskogee, Oklahoma. I have written about him in the Post “Lap o’ Luxury at the Muskogee Power Plant“. Each morning at Muskogee, he and Jay Harris would sing the song, “Nestle’s makes the very best Chocolate”, with Richard whistling as he sang like the Nestle’s rabbit with a whistle in his voice.

The Nestle's Rabbit

The Nestle’s Rabbit

On one particular day, Richard and I were sent to perform a “quick and dirty” elevator inspection on the Unit 1 elevator. It received a lot of wear and tear during overhaul with everyone riding up and down from the 9th floor where you could reach the upper echelons of the boiler. If things didn’t work perfectly every time, then the work would be slowed, and schedules wouldn’t be met.

During our elevator inspection we decided that we needed to change out some lights on the push buttons, because…. well… because some of them were burned out. Which caused them to not light up when they were supposed to, causing some Power Plant workers to become confused because they would forget which button they had pushed when they entered the elevator, thus, allowing them to forget which floor they were supposed to get off (working long hours will do that to you).

Anyway, Richard had taken the screws out of the push button panel and had swung the door on the panel open so that the wiring inside was all exposed. He reached in to pulled out one of the push button assemblies so that he could remove the bulb (oh… electricians call bulbs, Lamps… I mentioned that in the post “Place On Light Duty at the Power Plant“, if you recall).

I had reached down into my tool bucket and pulled out a box of special elevator lamps….. Actually, I think it was a standard 6S6 lamp, but it looked like a bulb to me:

A 12 Volt 6S6 bulb

Richard had put his hand out to receive the bulb I had in my hand, so I handed it to him. At that point, a funny thing happened. You see, my other hand was on the elevator scissor gate.

An Elevator Scissor Gate

As I placed the lamp into Richard’s hand, he suddenly twitched and sort of jumped at the same time. When he did, he pushed into me and he began doing a jig. My legs were twitching and I was sort of doing a jig myself, or maybe a jog.

It became apparent right away what had happened. While Richard’s one hand was in the elevator push button panel taking out the bulb, he had come in contact with the electric circuit. This was fine as long as he wasn’t grounded. That is, he wasn’t touching anything else metal, like the front of the panel.

Being a good electrician, Richard had kept his other hand at his side like Charles Foster had taught me my first day as an electrician. That is, until he raised that hand for me to give him a lamp. When my fingers touched his palm, and my other hand was holding the elevator gate, we suddenly made a circuit to ground. From Richard, to me, to the gate, to the ground, and back to the the main power generator through various grounds and circuits and transformers….

About the time that I realized what was happening, we had separated from each other, and were no longer dancing. It cracked us up and we stood there laughing about it for a minute because both of us had just been dancing in the elevator.

As I explained in the post about being on light duty that I mentioned above, when you went to work on the stack lights, you carried metal prod with you that you used to ground the large capacitors before you worked on the circuit. When you did this, there would be a bright flash and a loud explosion.

If a noise or a flash like that made you jump, you may end up going over the handrail and falling 500 feet to the ground. So, you learned that in the event of a flash, your first reaction is to freeze. Then assess the situation, and then if necessary, Panic.

Many years later (like 16), I became very aware of how well trained we were when something like this happened when I was once again working with Charles Foster in a junction box on the 11 landing of Unit 1 on the west side. We were standing side-by-side and we were working on something hot.

Suddenly there was a bright flash and a loud boom as something shorted out. By that time in our history, we had learned all about wearing fire resistant clothing, so that even though what we were wearing wasn’t fire proof, it also wasn’t going to melt to our skin.

What amazed me about this moment was that we both stood there still for a moment before we panicked. There was about a one second pause where we both restrained ourselves from jumping back. I chalked this up to our years of being around explosive situations. Jumping back as the first reaction can often lead to other injuries.

I took this resistance to panic with me into other situations. Before 1994 when OSHA added a bunch of new laws protecting people in confined spaces, I was crawling inside the main generator bus that goes out to the main power transformer. No hole watch. No one watching me outside that could grab me and pull me out if something went wrong.

A Main Power Transformer

A Main Power Transformer. The bus piping are those three pipes going into the building at the top in the back

I had squeezed myself into one of these pipes to clean the insulators that held the bus in place in the middle of the pipe. This meant that I was crammed into the pipe under the bus bar that ran through the middle of the pipe.

I had made it to the insulator that I needed to clean and wiped it down with the rag I had taken with me. Then I decided I couldn’t go forward anymore to look at any more of the insulators because it was too tight of a fit. So, I started to back myself out.

As I went to push myself back I suddenly realized that I was stuck. It was easy moving forward because I was using the soles of my sneakers to push on the pipe, but as soon as I wanted to go back, there didn’t seem to be anyway to maneuver my body in a way that would back myself out. My arms were stretched out in front of me.  This was one of a few times when I began to feel the panicky feeling of claustrophobia.

I had seen claustrophobia in others and I knew that when you are gripped with it, you can hurt yourself, or even Bob Lillibridge if he happened to be the one grabbing your legs at the time (see the post: Bob Lillibridge Meets the Power Plant Ghost for an explanation.

Here it came… I felt myself swelling up tight in the pipe as the panic was gripping me. I knew I had to do something quickly or it wasn’t going to be pretty…. Well, either way… nothing about this was pretty. So, I forced myself to calm down. I told myself to breathe out, and slowly back in.

Then I decided to use the palms of my hands that were stretched out straight in front of me to push against the pipe to move me back. With that effort, I could see (in the darkness) that I had moved myself back about 1/2 inch. I thought. “Ok, 1/2 inch is something. If I did that 100 more times, that would be more than 4 feet. 200 times and I would be out of this pipe.”

Realizing I could move myself at least a little bit allowed me to calm down and quell the panic. I did nothing but concentrate on pushing with my palms 1/2 inch at a time and eventually, I did climb out of that pipe (What?  You expected me to say I was still in there?).

I don’t know how many times over the years I have woken up in the middle of the night and swung my feet over the side of the bed and taken a few large breaths because I had been dreaming about being in that pipe again. I will discuss the topic of claustrophobia in a later post, but this example fit the topic of training yourself not to panic so I thought I would use it here.

If you ever end up talking to someone that doesn’t quite look at you when they look like they are trying to look at you, then you may think that they are a welder. There are some welders that seem to look at you from the corner of their eye. I suppose it was because the middle of their vision has been burned out because they have looked at the welding arc too many times without their visor down.  Or maybe they had just learned to look away from whatever they are seeing just as a safety habit.

Similarly, if you ever encounter someone that momentarily goes into a comatose state for a few moments when you ask them a simple question, you may now think that maybe this person was a Power Plant Electrician that has learned to have a Prolonged Pause before they Panic… or… respond to your question. If they aren’t from a power plant, then they probably were just trying to ignore you.

      Pause before panic is my response to most stressors perceived by a presenter or an emerging reality. You hit the mark!

  1. Monty Hansen November 26, 2014

    Excellent writing! I felt myself getting panicky with you! As a control room operator I had an electrician drop a screwdriver & blow the unit out from under me at full load + 5% overpressure (2520#)-(It caused a false boiler feedpump saturation temp trip). The power plant has trained me not to startle as well, inside I may be screaming like a schoolgirl, but outside I am calm and handling emergencies as though routine.

As I went to push myself back I suddenly realized that I was stuck. It was easy moving forward because I was using the soles of my sneakers to push on the pipe, but as soon as I wanted to go back, there didn’t seem to be anyway to maneuver my body in a way that would back myself out. My arms were stretched out in front of me.  This was one of a few times when I began to feel the panicky feeling of claustrophobia.

I had seen claustrophobia in others and I knew that when you are gripped with it, you can hurt yourself, or even Bob Lillibridge if he happened to be the one grabbing your legs at the time (see the post: Bob Lillibridge Meets the Power Plant Ghost for an explanation.

Here it came… I felt myself swelling up tight in the pipe as the panic was gripping me. I knew I had to do something quickly or it wasn’t going to be pretty…. Well, either way… nothing about this was pretty. So, I forced myself to calm down. I told myself to breathe out, and slowly back in.

Then I decided to use the palms of my hands that were stretched out straight in front of me to push against the pipe to move me back. With that effort, I could see (in the darkness) that I had moved myself back about 1/2 inch. I thought. “Ok, 1/2 inch is something. If I did that 100 more times, that would be more than 4 feet. 200 times and I would be out of this pipe.”

Realizing I could move myself at least a little bit allowed me to calm down and quell the panic. I did nothing but concentrate on pushing with my palms 1/2 inch at a time and eventually, I did climb out of that pipe (What?  You expected me to say I was still in there?).

I don’t know how many times over the years I have woken up in the middle of the night and swung my feet over the side of the bed and taken a few large breaths because I had been dreaming about being in that pipe again. I will discuss the topic of claustrophobia in a later post, but this example fit the topic of training yourself not to panic so I thought I would use it here.

If you ever end up talking to someone that doesn’t quite look at you when they look like they are trying to look at you, then you may think that they are a welder. There are some welders that seem to look at you from the corner of their eye. I suppose it was because the middle of their vision has been burned out because they have looked at the welding arc too many times without their visor down.  Or maybe they had just learned to look away from whatever they are seeing just as a safety habit.

Similarly, if you ever encounter someone that momentarily goes into a comatose state for a few moments when you ask them a simple question, you may now think that maybe this person was a Power Plant Electrician that has learned to have a Prolonged Pause before they Panic… or… respond to your question. If they aren’t from a power plant, then they probably were just trying to ignore you.

    Pause before panic is my response to most stressors perceived by a presenter or an emerging reality. You hit the mark!

    Excellent writing! I felt myself getting panicky with you! As a control room operator I had an electrician drop a screwdriver & blow the unit out from under me at full load + 5% overpressure (2520#)-(It caused a false boiler feedpump saturation temp trip). The power plant has trained me not to startle as well, inside I may be screaming like a schoolgirl, but outside I am calm and handling emergencies as though routine.

Placed on Light Duty at the Power Plant

In another profession being put on light duty may mean that you don’t have to work as hard as everyone else.  When an electrician is put on light duty it means something else entirely.  I think I calculated the number of lights and it was well over 10,000 light bulbs in the coal-fired power plant in North Central Oklahoma.  Ideally you would think that every one of the lights should be in good working order.

Electricians don’t call a light bulb a light.  The light is the fixture.  The bulb is called a “lamp”.  So, for the rest of this post I’ll call the light bulbs “lamps”.

You may think that it’s pretty straight forward to go change out lights (oh.  I mean… lamps), but it’s not.  You see, it isn’t like in your house where you have the regular light bulbs everywhere with just different shapes and wattage.  Sure, there were different Watts for the different lamps, but for a good number of the lights, they varied by voltage as well.

Not only that, but these lamps were different types of lights.  Most of which are not incandescent (well… now that the government has seen fit to force the lighting industry to stop making incandescent lamps altogether, I guess it wouldn’t seem odd to the younger folks).

In the office areas and places like the main switchgear 4 foot fluorescent lamps were used.  Each 4 foot fluorescent lamp is 40 watts.  Just because it is 40 watts, it doesn’t mean that the voltage is low.  It can take up to 650 volts to start up a fluorescent lamp.  A Fluorescent lamp actually has a gas in it that causes a coating on the glass to glow when a current flows across the gas.

A fluorescent Lamp

Besides the typical fluorescent lamps, the majority of the rest of the lamps in the plant were various sizes of Mercury Vapor lamps.  (now replaced with Sodium Vapor).

Before you become all twisted about using Mercury Vapor to light up a power plant because of the environmental impact, I think I should point out that even though a fluorescent lamp is filled with an inert gas like argon, it is mixed with Mercury vapor as well, and the phosphorous coating on the glass has mercury in it also.

So, if you have fluorescent lamps in your house…. Well, there you go.  And you know those lamps that are used to replace your old incandescent light bulbs….. Yep… and they have other kinds of hazardous metals as well.  I suppose it is good for the environment to take those hazardous materials out of the earth and put them in lamps in your houses.  Isn’t that improving the environment?

The thing about using Fluorescent lamps and Mercury Vapors and Sodium Vapor lamps is that they all use different voltages.  So, in order for them to start up and stay running, the voltages have to change from the start up voltage to the operating voltage.  Each lamp has it’s own transformer designed just for that one type of lamp.  It is placed in the light fixture for the lamp.

You can tell this is a 100 Watt Mercury Vapor lamp because of the 10.  If it had a 25, then it would be a 250 watt lamp.   Following the same logic if it has a 75 on it, then it is a 75 watt lamp..... oh...well.. the logic is there somewhere

If the light glows blue, then it is mercury vapor.  If it is orange then it is a sodium light.  Your street lights are the same way.  Well.  Now there is also Halogen lamps which shine white.

Besides these different type lamps, we also had some super special lights.  We have the flashing lights on the smoke stack and the red blinking light on the top of the radio tower.  The lights that flash on the smoke stacks are really flashbulbs.

A flash tube used in a smoke stack beacon that can easily be seen 50 miles away at night. Especially when the day time setting is still on

Our smoke stacks are 500 feet tall with beacons at the 250 foot level and the 500 foot level.  Not only did you have to change out the bulb, but you often had to change out the large capacitors and the circuit boards that had been fried by a passing lightning storm.

You may have heard that with the older style Television sets that had a picture tube (before the flat screen TVs came around), that you could electrocute yourself by taking the cover off the back of the TV and working on it, even though you unplugged the set from the wall before you started.  A few movies used this in the plot.  Robert T. Ironside even used it once in an episode during the first season.

Robert T. Ironside played by Raymond Burr

Well.  The Stack lights are like that.  When we opened up the light fixture to work on the flash tube or the circuits inside the first thing you did was take a metal rod with a wooden handle and a wire attached with a clip on the end and clipped the wire to the handrail.  Then turning your head the other way, you placed the metal rod across each of the large capacitors in the box.   Invariably, one of the capacitors would let out a loud pop that would echo across the lake…. oh, and leave your ears ringing.

Once the voltage was discharged from all the capacitors, you knew it was safe to go to work fixing the light.  The lights had a day and a night mode, and the difference was how many times the flash tube flashed when it discharged.  What I mean to say is that it wasn’t just one flash.  It is really a series of flashes closely timed to look like one flash.  The number of flashes and the timing between the flashes determine how bright the flash is.

At night the flash was much dimmer because it didn’t need to be so bright.  When it was stuck in the day mode at night the farmers for a 30 mile radius would be calling saying they can’t sleep because every 6 seconds their bedroom would light up as the smoke stack lights would blink.

I thought I would just put that picture in there so you could see how pretty the plant looked from across the lake at sunset.  To me it looked like a big ship on the horizon.

I mentioned above that there was a radio tower that had a light on it that needed to be changed when it burned out.  The actual lamp looked a lot like a regular incandescent bulb in your house, but it was different.  It was designed just for this job.  It didn’t burn out very often.  Ok.  I can see your look of disbelief, so here is a picture of one:

A radio tower light bulb

Yeah, looks just like something in your house.  Doesn’t it?

Anyway.  I changed out the light at the top of our radio tower which is only about 200 feet tall.  It looked like the following picture:

Our tower was like this only it didn't have a safety pole up the side for a lanyard.

Our tower was like this only it didn’t have a safety pole up the side for a lanyard.

I had to climb to the top of this tower to replace the red flashing light.  I was by myself when I did it.  Bill Bennett handed me the bulb that had been specially ordered and asked me if I would do it.  If not, they could call Oklahoma City and have the line crew come down and change it.  I told him I could do it.  The tower wasn’t that tall, and I had shimmied around the top of the smoke stack before at 500 feet with only a slight urge to panic.

I changed the lamp out without incident.  I know that some people have a much more interesting job changing these lights out than I had.  Our radio tower was only 200 feet tall.  Here is a video of someone that had to climb a tower 1768 feet high.  You can see the beacon when they reach the top of this radio tower:

if your browser doesn’t play the video from the picture try this link:  “Climbing a 1768 foot tower“.

Ok.  That is crazy!  Wouldn’t dropping someone from a helicopter onto the tower using a safety line be safer?

My last story about being on light duty at a power plant is about when Ted Riddle and I were working at the gas-fired power plant near Mustang, Oklahoma.  I talked about the time that Ted and I worked at this plant in the post “Working Power Plant Wonders with Willard Stark

While we were there after they found out that we were electric conduit running fools, they gave us all sorts of jobs running conduit all over the plant.  One job they showed us was in an area that was dark.  All the lights were out in this area.  The foreman explained where the light bulbs were kept.  They were just the regular incandescent lights like the normal lights you would have in your house.

Well… Ted and I had both been put on Light Duty at our plant, and we knew that when we went to change out one light, we were supposed to change out all the lights that were out.  So, Ted and I each grabbed a box and a ladder and headed up to the boiler enclosure to change lights.

After lunch, the foreman came running up to us yelling, “What did you do?  You used up all of the light bulbs!”  Well.  Yes.  We had used up the lights, but now when you go up on the boiler you can see where you are going.  The foreman then explained to us  that this little plant didn’t have the same kind of budget that the new big plants had.  They couldn’t afford to just go around replacing all the lights whenever they burned out.  They only put in a light when someone has to work in that area.  We had lit the entire place up like a Christmas tree.

Ok.  Take a note Jan… Don’t replace all the lights if they are incandescent.

Ok (again), that wasn’t quite the last story.  Let me tell you some more about replacing Fluorescent lamps in our Coal-fired power plant.  When we were placed on Light Duty, we would grab a couple of boxes of 30 lamps from the pallet in the main switchgear and go to work.

In the main switchgear the lights were up high, so we used a 10 foot ladder with a stand on the top of it (No.  I don’t mean like a Deer stand…. geez… Power Plant men…. always thinkin’ ’bout huntin’).  Actually it is called a Platform ladder:

This is a 6 foot platform ladder.  Ours was 10 foot and very wobbly

This is a solid 6 foot platform ladder. Ours was 10 foot and very wobbly

I didn’t like using this wobbly ladder when I was by myself.  besides being wobbly, the thing weighed a ton.  So, I would take a smaller ladder and put it on top of the breaker cabinets and climb on top of them.  The only problem here was that I couldn’t get directly under the lights, so I would end up reaching out to one side to change a light while I was standing on a ladder on top of a seven foot cabinet.  Not a pretty sight if someone safety minded walked in.

I felt safer doing this than standing way up in the air on a 10 foot wobbly platform ladder.  I always had the feeling that if I sneezed, the ladder would topple over.  The rule of thumb was to keep your belt buckle within the rungs on the ladder.

When we were done changing out fluorescent lamps, we usually had a stack of boxes of burned out lamps.  We couldn’t just throw them in the dumpster because they were a safety hazard as they were.  We had to break each bulb.  We found that we could take a box of 4 foot fluorescent lamps and back the truck over it and it would let out a low but loud boom that sounded like a cannon going off.

The ingenious electricians invented a bulb busting barrel where you slid one 4 foot bulb into a tube and then lifted a handle quickly, and it would explode the lamp in the safe confines of the metal barrel.  The end of the lamp may at times come shooting out the end of the tube, so you never wanted to be standing to that side of the barrel.  I would show you a picture of one, but I’ve never found another one like it.

So, if you were into breaking glass, this was the best part of being placed on Light Duty.  After a hard day of changing out lamps all over the plant, you could stand around in front of the electric shop and slide the lamps down a tube like mortar shell and pull the rod and…. Boom! A puff of Mercury Vapor released into the atmosphere a small cloud of dust…. repeat.

    I remember being on “Light Duty” at the Mustang Power Plant as a summer student in 1967. We changed the 1000 watt bulbs in the top of the turbine room. It was so hot, we had to wear gloves.

Prolonged Power Plant Pause Before the Panic — Repost

Originally posted September 6, 2013:

Today when I attend meetings while on the job at Dell and the discussion is about something new, and the manager is looking for input from the team, I usually sit there quiety while the others share their thoughts.  This is not my usual behavior as I am usually quick to respond with a quip or something sarcastic.

Later, after everyone else has given their two cents, then if asked, I will wade in with both feet.  This hasn’t always been the course of action I would have taken.  Actually, I used to be pretty hot-headed.  I was usually the first person to respond when someone asked a question.  I already had my mind made up about just about everything.

My wife began noticing a change in my behavior a few years after we were married.  She would ask me a simple question, like, “Would you like a piece of gum.”  I would suddenly go into a momentary comatose state where I would stare off into space and think about it.  She would say something like, “The answer doesn’t need a lot of thought.  It is either ‘yes’ or ‘no’.”

After careful analysis, I finally figured out what happened.  The transformation began the day I entered the electric shop at the coal-fired power plant as an electrician.  I described that first day in the post “New Home in the Power Plant Electric Shop“.  In that post I described my first job as an electrician when I went to the coalyard with my foreman Charles Foster to fix a room heater that wasn’t working.

The first time I used my new tools, Charles told me to remove a screw from a fuse block so that we could lift a wire in order to replace the fuse block.

A small fuse block like this.

A small fuse block like this.

When I was removing the wire (with one hand, as Charles had warned me that an electrician never uses two hands to do this), the screwdriver slipped and shorted out on the mounting screw which caused a brief flash.  In the millisecond that the flash occurred, it cut a notch in the tip of my new Stanley screwdriver.

A Stanley screwdriver used by electgricians because of the rubber on the handle

This was the beginning of my 18 year career of various minor electrocutions and small explosions.  We did things to minimize the chances of shorting out your screwdriver when working on a hot circuit (that means a circuit that has the electricity still turned on).  One thing we would do is wrap rubber tape up the metal shank so that if it leaned against something metal with it while the tip was touching something hot, it wouldn’t short out the circuit.

Inevitably, something would happen every now and then and something was going to explode.  So you just had to be prepared for that.  This is where the “Prolonged Pause” comes in.

Sometimes there is nothing you can do.  Let me give you a “For Instance”.  One time when we had an overhaul on Unit 1 (we had 2 units at our Power Plant in North Central Oklahoma), Richard Moravek was visiting from the Power Plant in Muskogee, Oklahoma.  I have written about him in the Post “Lap o’ Luxury at the Muskogee Power Plant“.  Each morning at Muskogee, he and Jay Harris would sing the song, “Nestle’s makes the very best Chocolate”, with Richard whistling as he sang like the Nestle’s rabbit.

The Nestle's Rabbit

The Nestle’s Rabbit

On one particular day, Richard and I were sent to perform a “quick and dirty” elevator inspection on the Unit 1 elevator.  It received a lot of wear and tear during overhaul with everyone riding up and down from the 9th floor where you could reach the upper echelons of the boiler.  If things didn’t work perfectly every time, then the work would be slowed, and schedules wouldn’t be met.

During our elevator inspection we decided that we needed to change out some lights on the push buttons, because…. well… because some of them were burned out.  Which caused them to not light up when they were supposed to, causing some Power Plant workers to become confused because they would forget which button they had pushed when they entered the elevator, thus, allowing them to forget which floor they were supposed to get off.

Anyway, Richard had taken the screws out of the push button panel and had swung the door on the panel open so that the wiring inside was all exposed.  He reached in to pulled out one of the push button assemblies so that he could remove the bulb (oh… electricians call bulbs, Lamps… I mentioned that in the post “Place On Light Duty at the Power Plant“, if you recall).

I had reached down into my tool bucket and pulled out a box of special elevator lamps….. Actually, I think it was a standard 6S6 lamp, but it looked like a bulb to me:

A 12 Volt 6S6 bulb

A 12 Volt 6S6 bulb

Richard had put his hand out to receive the bulb I had in my hand, so I handed it to him.  At that point, a funny thing happened.  You see, my other hand was on the elevator scissor gate.

An Elevator Scissor Gate

An Elevator Scissor Gate

As I placed the lamp into Richard’s hand, he suddenly twitched and sort of jumped at the same time.  When he did, he pushed into me and he began doing a jig.  My legs were twitching and I was sort of doing a jig myself, or maybe a jog.

It became apparent right away what had happened.  While Richard’s one hand was in the elevator push button panel taking out the bulb, he had come in contact with the electric circuit.  This was fine as long as he wasn’t grounded.  That is, he wasn’t touching anything else metal, like the front of the panel.

Being a good electrician, Richard had kept his other hand at his side like Charles Foster had taught me my first day as an electrician.  That is, until he raised that hand for me to give him a lamp.  When my fingers touched his palm, and my other hand was holding the elevator gate, we suddenly made a circuit to ground.  From Richard, to me, to the gate, to the ground, and back to the the main power generator through various grounds and circuits and transformers….

About the time that I realized what was happening, we had separated from each other, and were no longer dancing.  It cracked us up and we stood there laughing about it for a minute because both of us had just been dancing in the elevator.

As I explained in the post about being on light duty that I mentioned above, when you went to work on the stack lights, you carried metal prod with you that you used to ground the large capacitors before you worked on the circuit.  When you did this, there would be a bright flash and a loud explosion.

If a noise or a flash like that made you jump, you may end up going over the handrail and falling 500 feet to the ground.  So, you learned that in the event of a flash, your first reaction is to freeze.  Then assess the situation, and then if necessary, Panic.

Many years later (like 16), I became very aware of how well trained we were when something like this happened when I was once again working with Charles Foster in a junction box on the 11 landing of Unit 1 on the west side.  We were standing side-by-side and we were working on something hot.

Suddenly there was a bright flash and a loud boom as something shorted out.  By that time in our history, we had learned all about wearing fire resistant clothing, so that even though what we were wearing wasn’t fire proof, it also wasn’t going to melt to our skin.

What amazed me about this moment was that we both stood there still for a moment before we panicked.  There was about a one second pause where we both restrained ourselves from jumping back.  I chalked this up to our years of being around explosive situations.  Jumping back as the first reaction can often lead to other injuries.

I took this resistance to panic with me into other situations.  Before 1994 when OSHA added a bunch of new laws protecting people in confined spaces, I was crawling inside the main generator bus that goes out to the main power transformer.  No hole watch.  No one watching me outside that could grab me and pull me out if something went wrong.

I had squeezed myself into one of these pipes to clean the insulators that held the bus in place in the middle of the pipe.  This meant that I was crammed into the pipe under the bus bar that ran through the middle of the pipe.

I had made it to the insulator that I needed to clean and wiped it down with the rag I had taken with me.  Then I decided I couldn’t go forward anymore to look at any more of the insulators because it was too tight of a fit.  So, I started to back myself out.

Once the voltage was discharged from all the capacitors, you knew it was safe to go to work fixing the light.  The lights had a day and a night mode, and the difference was how many times the flash tube flashed when it discharged.  What I mean to say is that it wasn’t just one flash.  It is really a series of flashes closely timed to look like one flash.  The number of flashes and the timing between the flashes determine how bright the flash is.

At night the flash was much dimmer because it didn’t need to be so bright.  When it was stuck in the day mode at night the farmers for a 30 mile radius would be calling saying they can’t sleep because every 6 seconds their bedroom would light up as the smoke stack lights would blink.

I thought I would just put that picture in there so you could see how pretty the plant looked from across the lake at sunset.  To me it looked like a big ship on the horizon.

I mentioned above that there was a radio tower that had a light on it that needed to be changed when it burned out.  The actual lamp looked a lot like a regular incandescent bulb in your house, but it was different.  It was designed just for this job.  It didn’t burn out very often.  Ok.  I can see your look of disbelief, so here is a picture of one:

Yeah, looks just like something in your house.  Doesn’t it?

Anyway.  I changed out the light at the top of our radio tower which is only about 200 feet tall.  It looked like the following picture:

Our tower was like this only it didn't have a safety pole up the side for a lanyard.

I had to climb to the top of this tower to replace the red flashing light.  I was by myself when I did it.  Bill Bennett handed me the bulb that had been specially ordered and asked me if I would do it.  If not, they could call Oklahoma City and have the line crew come down and change it.  I told him I could do it.  The tower wasn’t that tall, and I had shimmied around the top of the smoke stack before at 500 feet with only a slight urge to panic.

I changed the lamp out without incident.  I know that some people have a much more interesting job changing these lights out than I had.  Our radio tower was only 200 feet tall.  Here is a video of someone that had to climb a tower 1768 feet high.  You can see the beacon when they reach the top of this radio tower:

Ok.  That is crazy!  Wouldn’t dropping someone from a helicopter onto the tower using a safety line be safer?

My last story about being on light duty at a power plant is about when Ted Riddle and I were working at the gas-fired power plant near Mustang, Oklahoma.  I talked about the time that Ted and I worked at this plant in the post “Working Power Plant Wonders with Willard Stark

While we were there after they found out that we were electric conduit running fools, they gave us all sorts of jobs running conduit all over the plant.  One job they showed us was in an area that was dark.  All the lights were out in this area.  The foreman explained where the light bulbs were kept.  They were just the regular incandescent lights like the normal lights you would have in your house.

Well… Ted and I had both been put on Light Duty at our plant, and we knew that when we went to change out one light, we were supposed to change out all the lights.  So, Ted and I each grabbed a box and a ladder and headed up to the boiler enclosure to change lights.

After lunch, the foreman came running up to us yelling, “What did you do?  You used up all of the light bulbs!”  Well.  Yes.  We had used up the lights, but now when you go up on the boiler you can see where you are going.  The foreman then explained to us  that this little plant didn’t have the same kind of budget that the new big plants had.  They couldn’t afford to just go around replacing all the lights whenever they burned out.  They only put in a light when someone has to work in that area.  We had lit the entire place up like a Christmas tree.

Ok.  Take a note Jan… Don’t replace all the lights if they are incandescent.

Ok (again), that wasn’t quite the last story.  Let me tell you some more about replacing Fluorescent lamps in our Coal-fired power plant.  When we were placed on Light Duty, we would grab a couple of boxes of 30 lamps from the pallet in the main switchgear and go to work.

In the main switchgear the lights were up high, so we used a 10 foot ladder with a stand on the top of it (No.  I don’t mean like a Deer stand…. geez… Power Plant men…. always thinkin’ ’bout huntin’).  Actually it is called a Platform ladder:

This is a 6 foot platform ladder.  Ours was 10 foot and very wobbly

This is a solid 6 foot platform ladder. Ours was 10 foot and very wobbly

I didn’t like using this wobbly ladder when I was by myself.  besides being wobbly, the thing weighed a ton.  So, I would take a smaller ladder and put it on top of the breaker cabinets and climb on top of them.  The only problem here was that I couldn’t get directly under the lights, so I would end up reaching out to one side to change a light while I was standing on a ladder on top of a seven foot cabinet.  Not a pretty sight if someone safety minded walked in.

I felt safer doing this than standing way up in the air on a 10 foot wobbly platform ladder.  I always had the feeling that if I sneezed, the ladder would topple over.

When we were done changing out fluorescent lamps, we usually had a stack of boxes of burned out lamps.  We couldn’t just throw them in the dumpster because they were a safety hazard as they were.  We had to break each bulb.  We found that we could take a box of 4 foot fluorescent lamps and back the truck over it and it would let out a low but loud boom that sounded like a cannon going off.

The ingenious electricians invented a bulb busting barrel where you slid one 4 foot bulb into a tube and then lifted a handle quickly, and it would explode the lamp in the safe confines of the metal barrel.  The end of the lamp may at times come shooting out the end of the tube, so you never wanted to be standing to that side of the barrel.  I would show you a picture of one, but I’ve never found another one like it.

So, if you were into breaking glass, this was the best part of being placed on Light Duty.  After a hard day of changing out lamps all over the plant, you could stand around in front of the electric shop and slide the lamps down a tube like mortar shell and pull the rod and…. Boom! A puff of Mercury Vapor released into the atmosphere a small cloud of dust…. repeat.

Prolonged Power Plant Pause Before the Panic

Today when I attend meetings while on the job at Dell and the discussion is about something new, and the manager is looking for input from the team, I usually sit there quiety while the others share their thoughts.  This is not my usual behavior as I am usually quick to respond with a quip or something sarcastic.

Later, after everyone else has given their two cents, then if asked, I will wade in with both feet.  This hasn’t always been the course of action I would have taken.  Actually, I used to be pretty hot-headed.  I was usually the first person to respond when someone asked a question.  I already had my mind made up about just about everything.

My wife began noticing a change in my behavior a few years after we were married.  She would ask me a simple question, like, “Would you like a piece of gum.”  I would suddenly go into a momentary comatose state where I would stare off into space and think about it.  She would say something like, “The answer doesn’t need a lot of thought.  It is either ‘yes’ or ‘no’.”

After careful analysis, I finally figured out what happened.  The transformation began the day I entered the electric shop at the coal-fired power plant as an electrician.  I described that first day in the post “New Home in the Power Plant Electric Shop“.  In that post I described my first job as an electrician when I went to the coalyard with my foreman Charles Foster to fix a room heater that wasn’t working.

The first time I used my new tools, Charles told me to remove a screw from a fuse block so that we could lift a wire in order to replace the fuse block.

A small fuse block like this.

A small fuse block like this.

When I was removing the wire (with one hand, as Charles had warned me that an electrician never uses two hands to do this), the screwdriver slipped and shorted out on the mounting screw which caused a brief flash.  In the millisecond that the flash occurred, it cut a notch in the tip of my new Stanley screwdriver.

This was the beginning of my 18 year career of various minor electrocutions and small explosions.  We did things to minimize the chances of shorting out your screwdriver when working on a hot circuit (that means a circuit that has the electricity still turned on).  One thing we would do is wrap rubber tape up the metal shank so that if it leaned against something metal with it while the tip was touching something hot, it wouldn’t short out the circuit.

Inevitably, something would happen every now and then and something was going to explode.  So you just had to be prepared for that.  This is where the “Prolonged Pause” comes in.

Sometimes there is nothing you can do.  Let me give you a “For Instance”.  One time when we had an overhaul on Unit 1 (we had 2 units at our Power Plant in North Central Oklahoma), Richard Moravek was visiting from the Power Plant in Muskogee, Oklahoma.  I have written about him in the Post “Lap o’ Luxury at the Muskogee Power Plant“.  Each morning at Muskogee, he and Jay Harris would sing the song, “Nestle’s makes the very best Chocolate”, with Richard whistling as he sang like the Nestle’s rabbit.

The Nestle's Rabbit

The Nestle’s Rabbit

On one particular day, Richard and I were sent to perform a “quick and dirty” elevator inspection on the Unit 1 elevator.  It received a lot of wear and tear during overhaul with everyone riding up and down from the 9th floor where you could reach the upper echelons of the boiler.  If things didn’t work perfectly every time, then the work would be slowed, and schedules wouldn’t be met.

During our elevator inspection we decided that we needed to change out some lights on the push buttons, because…. well… because some of them were burned out.  Which caused them to not light up when they were supposed to, causing some Power Plant workers to become confused because they would forget which button they had pushed when they entered the elevator, thus, allowing them to forget which floor they were supposed to get off.

Anyway, Richard had taken the screws out of the push button panel and had swung the door on the panel open so that the wiring inside was all exposed.  He reached in to pulled out one of the push button assemblies so that he could remove the bulb (oh… electricians call bulbs, Lamps… I mentioned that in the post “Place On Light Duty at the Power Plant“, if you recall).

I had reached down into my tool bucket and pulled out a box of special elevator lamps….. Actually, I think it was a standard 6S6 lamp, but it looked like a bulb to me:

A 12 Volt 6S6 bulb

A 12 Volt 6S6 bulb

Richard had put his hand out to receive the bulb I had in my hand, so I handed it to him.  At that point, a funny thing happened.  You see, my other hand was on the elevator scissor gate.

An Elevator Scissor Gate

As I placed the lamp into Richard’s hand, he suddenly twitched and sort of jumped at the same time.  When he did, he pushed into me and he began doing a jig.  My legs were twitching and I was sort of doing a jig myself, or maybe a jog.

It became apparent right away what had happened.  While Richard’s one hand was in the elevator push button panel taking out the bulb, he had come in contact with the electric circuit.  This was fine as long as he wasn’t grounded.  That is, he wasn’t touching anything else metal, like the front of the panel.

Being a good electrician, Richard had kept his other hand at his side like Charles Foster had taught me my first day as an electrician.  That is, until he raised that hand for me to give him a lamp.  When my fingers touched his palm, and my other hand was holding the elevator gate, we suddenly made a circuit to ground.  From Richard, to me, to the gate, to the ground, and back to the the main power generator through various grounds and circuits and transformers….

About the time that I realized what was happening, we had separated from each other, and were no longer dancing.  It cracked us up and we stood there laughing about it for a minute because both of us had just been dancing in the elevator.

As I explained in the post about being on light duty that I mentioned above, when you went to work on the stack lights, you carried metal prod with you that you used to ground the large capacitors before you worked on the circuit.  When you did this, there would be a bright flash and a loud explosion.

If a noise or a flash like that made you jump, you may end up going over the handrail and falling 500 feet to the ground.  So, you learned that in the event of a flash, your first reaction is to freeze.  Then assess the situation, and then if necessary, Panic.

Many years later (like 16), I became very aware of how well trained we were when something like this happened when I was once again working with Charles Foster in a junction box on the 11 landing of Unit 1 on the west side.  We were standing side-by-side and we were working on something hot.

Suddenly there was a bright flash and a loud boom as something shorted out.  By that time in our history, we had learned all about wearing fire resistant clothing, so that even though what we were wearing wasn’t fire proof, it also wasn’t going to melt to our skin.

What amazed me about this moment was that we both stood there still for a moment before we panicked.  There was about a one second pause where we both restrained ourselves from jumping back.  I chalked this up to our years of being around explosive situations.  Jumping back as the first reaction can often lead to other injuries.

I took this resistance to panic with me into other situations.  Before 1994 when OSHA added a bunch of new laws protecting people in confined spaces, I was crawling inside the main generator bus that goes out to the main power transformer.  No hole watch.  No one watching me outside that could grab me and pull me out if something went wrong.

A Main Power Transformer

A Main Power Transformer.  The bus piping are those three pipes going into the building at the top in the back

I had squeezed myself into one of these pipes to clean the insulators that held the bus in place in the middle of the pipe.  This meant that I was crammed into the pipe under the bus bar that ran through the middle of the pipe.

I had made it to the insulator that I needed to clean and wiped it down with the rag I had taken with me.  Then I decided I couldn’t go forward anymore to look at any more of the insulators because it was too tight of a fit.  So, I started to back myself out.

As I went to push myself back I suddenly realized that I was stuck.  It was easy moving forward because I was using the soles of my sneakers to push on the pipe, but as soon as I wanted to go back, there didn’t seem to be anyway to maneuver my body in a way that would back myself out.  This was one of a few times when I began to feel the panicky feeling of claustrophobia.

I had seen claustrophobia in others and I knew that when you are gripped with it, you can hurt yourself, or even Bob Lillibridge if he happened to be grabbing your legs at the time (see the post:  Bob Lillibridge Meets the Power Plant Ghost for an explanation.

Here it came… I felt myself swelling up tight in the pipe as the panic was gripping me.  I knew I had to do something quickly or it wasn’t going to be pretty…. Well, either way… nothing about this was pretty.  So, I forced myself to calm down.  I told myself to breathe out, and slowly back in.

Then I decided to use the palms of my hands that were stretched out straight in front of me to push against the pipe to move me back.  With that effort, I could see (in the darkness) that I had moved myself back about 1/2 inch.  I thought.  “Ok, 1/2 inch is something.  If I did that 100 more times, that would be more than 4 feet.  200 times and I would be out of this pipe.”

Realizing I could move myself at least a little bit allowed me to calm down and quell the panic.  I did nothing but concentrate on pushing with my palms 1/2 inch at a time and eventually, I did climb out of that pipe (What you expected me to say I was still in there?).

I don’t know how many times over the years I have woken up in the middle of the night and swung my feet over the side of the bed and taken a few large breaths because I had been dreaming about being in that pipe again.  I will discuss the top of claustrophobia in a later post, but this example fit the top of training yourself not to panic so I thought I would use it here.

If you ever end up talking to someone that doesn’t quite look at you when they look like they are trying to look at you, then you may think that they are a welder.  There are some welders that seem to look at you from the corner of their eye.  I suppose it was because the middle of their vision has been burned out because they have looked at the welding arc too many times without their visor down.

Similarly, if you ever encounter someone that momentarily goes into a comatose state for a few moments when you ask them a simple question, you may now think that maybe this person was a Power Plant Electrician that has learned to have a Prolonged Pause before they Panic… or.. well, respond to your question.  If they aren’t, then they probably were just trying to ignore you.

Placed on Light Duty at the Power Plant

In another profession being put on light duty may mean that you don’t have to work as hard as everyone else.  When an electrician is put on light duty it means something else entirely.  I think I calculated the number of lights at the plant and it was well over 10,000 light bulbs in the coal-fired power plant in North Central Oklahoma.  Ideally you would think that everyone of the lights should be in good working order.

Electricians don’t call a light bulb a light.  The light is the fixture.  The bulb is called a “lamp”.  So, for the rest of this post I’ll call the light bulbs lamps.

You may think that it’s pretty straight forward to go change out lights (oh.  I mean… lamps), but it’s not.  You see, it isn’t like in your house where you have the regular light bulbs everywhere with just different shapes and wattage.  Sure, there were different Watts for the different lamps, but for a good number of the lights, they varied by voltage as well.   Not only that, but these lamps were different types of lights.  Most of which are not incandescent (well… now that the government has seen fit to force the lighting industry to stop making incandescent lamps altogether, I guess it wouldn’t seem odd to the younger folks).

A descriptive picture of an Incandescent lamp found at www.techlinea.com

In the office areas and places like the main switchgear 4 foot fluorescent lamps were used.  Each 4 foot fluorescent lamp is 40 watts.  Just because it is 40 watts, it doesn’t mean that the voltage is low.  It can take up to 650 volts to start up a fluorescent lamp.  A Fluorescent lamp actually has a gas in it that causes a coating on the glass to glow when a current flows across the gas.

A fluorescent Lamp

A fluorescent Lamp

Besides the typical fluorescent lamps, the majority of the rest of the lamps in the plant were various sizes of Mercury Vapor lamps.  (now replaced with Sodium Vapor).

Before you become all twisted about using Mercury Vapor to light up a power plant because of the environmental impact, I think I should point out that even though a fluorescent lamp is filled with an inert gas like argon, it is mixed with Mercury vapor as well, and the phosphorous coating on the glass has mercury in it also.  So, if you have fluorescent lamps in your house…. Well, there you go.  And you know those lamps that are used to replace your old incandescent light bulbs….. Yep… and they have other kinds of hazardous metals as well.

The thing about using Fluorescent lamps and Mercury Vapors and Sodium Vapor lamps is that they all use different voltages.  So, in order for them to start up and stay running, the voltages have to change from the start up voltage to the operating voltage.  Each lamp has it’s own transformer designed just for that one type of lamp.  It is placed in the light fixture for the lamp.

You can tell this is a 100 Watt Mercury Vapor lamp because of the 10.  If it had a 25, then it would be a 250 watt lamp.   Following the same logic if it has a 75 on it, then it is a 75 watt lamp..... oh...well.. the logic is there somewhere

If the light glows blue, then it is mercury vapor.  If it is orange then it is a sodium light.  Your street lights are the same way.  Well.  Now there is also Halogen lamps which shine white.

Besides these different type lamps, we also had some super special lights.  We have the flashing lights on the smoke stack and the red blinking light on the top of the radio tower.  The lights that flash on the smoke stacks are really flashbulbs.

A flash tube used in a smoke stack beacon that can easily be seen 50 miles away at night. Especially when the day time setting is still on

Our smoke stacks are 500 feet tall with beacons at the 250 foot level and the 500 foot level.  Not only did you have to change out the bulb, but you often had to change out the large capacitors and the circuit boards that had been fried by a passing lightning storm.

You may have heard that with the older style Television sets that had a picture tube (before the flat screen TVs came around), that you could electrocute yourself by taking the cover off the back of the TV and working on it, even though you unplugged the set from the wall before you started.  A few movies used this in the plot.  Robert T. Ironside even used it once in an episode during the first season.

Well.  The Stack lights are like that.  When we opened up the light fixture to work on the flash tube or the circuits inside the first thing you did was take a metal rod with a wooden handle and a wire attached with a clip on the end and clipped the wire to the handrail.  Then turning your head the other way, you placed the metal rod across each of the large capacitors in the box.   Invariably, one of the capacitors would let out a loud pop that would echo across the lake…. oh, and leave your ears ringing.

Once the voltage was discharged from all the capacitors, you knew it was safe to go to work fixing the light.  The lights had a day and a night mode, and the difference was how many times the flash tube flashed when it discharged.  What I mean to say is that it wasn’t just one flash.  It is really a series of flashes closely timed to look like one flash.  The number of flashes and the timing between the flashes determine how bright the flash is.

At night the flash was much dimmer because it didn’t need to be so bright.  When it was stuck in the day mode at night the farmers for a 30 mile radius would be calling saying they can’t sleep because every 6 seconds their bedroom would light up as the smoke stack lights would blink.
