It just so happened that Oklahoma State University in Stillwater has one of the leading Fire Protection and Safety schools in the country. They offer Fire Service Training for companies who need to train their employees how to fight fires. As a summer help I was fortunate enough to take the onsite training that they provided at the power plant about every other summer to train the employees how to put out difficult fires.
It does sound like a good idea considering that there was all this coal laying around that had the habit of spontaneously igniting into smoldering embers that could easily lead to a large raging ball of flames. In fact, the Coal Yard heavy equipment operators had to drive their large dirt movers over and over the coal on the coal pile to pack it down because if it was exposed to too much air, it would develop hot spots that would turn into smoldering piles of coal that were nearly impossible to put out.
I have seen a spot smoldering on the coal pile where a water wagon would drench it with water over and over. That only seemed to keep it from spreading as fast. The only way to deal with it was to drag the burning coal off of the pile and let it burn itself out.
You would think that the OSU Fire Training Service would do a good job of teaching the employees the proper use of the fire extinguishers, and they did. The plant was loaded with Fire Extinguishers. As a summer help and labor crew hand, we would have to do a monthly inspection of all the plant extinguishers to check their pressures and initial the inspection sticker showing that we had been by to check it.
This was a practice that would later change to once each quarter when the Power Plant Men were strung out too thin and the labor crew no longer existed. Even later, the operators inspected them as they made their rounds, since they walked by them during their shifts anyway.
The plant had more than just the regular chemical fire extinguishers, it had the larger roll-around type in a few places as well:
The Fire Training Service trained us to use this as well. Actually, they motivated us to go out and buy fire extinguishers to put in our own homes. Which came in handy for me one year when an air condition repairman was using a blow torch in my house to cut out the cooling coils but forgot to take out the filter first.
The moment I saw him light up his torch, I pulled out the extinguisher from under the sink and set it on the counter. As I watched him, he suddenly started jerking back and forth. I figured something was up, so I pulled the pin, and when he was finally able to pull the burning filter out of the air duct, I was ready to blast it with the extinguisher. So, I gratefully thank the electric company for properly training us to use the handy dandy fire extinguishers that you might use around the house.
One important thing that you learn about the little extinguishers in your house is that they don’t really go very far before they run out of chemicals. So, you have to get the job done quickly while the fire is still small and manageable.
When I first heard that we were going to be trained to fight fires the second summer I was at the plant as a summer help, I was pretty excited. Wow… Great!!! Fight Fires! That sounds fun. A day of watching safety videos and playing with fire extinguishers. I didn’t realize at the time that there was a reason why OSU Fire Training Service was the best fire training school in the radius of about 1,000 miles.
Sure. We watched the training videos. We learned all about proper fire extinguisher care and maintenance. We heard stories about how small fires turned into raging infernos that burned companies right out of business. One thing I remember is that some large percentage of companies that have a major fire are never able to recover to the point that they go completely out of business.
If you need the exact percentage, I suggest you call up the OSU School of Fire Protection and Safety. They probably have the latest statistic printed on their school lunch napkins, because these guys eat, drink and sleep fire safety.
Then, after they had impressed us with their Fire Safety Prowess, they said, “Let’s take about a 15 minute break, and we will meet outside just north of the water treatment plant where we will resume your lessons. Oh, and bring your rubber boots and maybe a rain suit.” Rain Suit? What? It’s about 100 degrees outside. “I wouldn’t mind getting a little wet”, I thought to myself. — The simpleminded summer help that I was at the time.
I would describe in detail to you how they had this obstacle course of staircases and pipes and other metal structures all sitting in a big tray. It’s enough to say that it was quite a tangled mess of a contraption.
“Interesting.” I thought… Are we going to climb the staircase and shoot the fire from up above with our handy dandy fire extinguishers which were lined up in a row off to one side? Climbing over pipes to fight a fire under the stairs maybe… Do we get to use the big roll around fire extinguisher that was there too? This looks like it might be fun.
That was when the fun began. One of the trainers turned a valve, and then I noticed that there was a fairly large tank there also that was hooked up to the pipes that wound around the mocked up structure of a stairway and other obstacles in the large tray. As he turned the valve, what looked like diesel or kerosene like petroleum product came spraying out of various holes in the piping spraying everything in the tray drenching it with fuel.
This other guy had a long rod that he had lit like a large lighter only it was giant size, and after the fuel had been spraying out for a while, he lowered the flame down into the tray that now was beginning to fill up with some kind of oily substance. He lit it and the flames quickly spread over the entire structure. He had us go in groups of 4 people with fire extinguishers to try to put out the fire. As their extinguishers ran out of fuel, others waiting behind would take their place trying to put out the fire.
We would chase the fire around the structure trying to put it out, but it wasn’t as easy as you would think. If you didn’t completely suffocate it by hitting it from many different directions and in a pattern from one end to the other just right, the fire would dodge around the spray from the extinguishers to be right back where you started. By the time we had used up all the extinguishers, we may have put the fire out about 3 times.
Rubber boots… I kept thinking…. my feet are getting hot… You couldn’t hardly get close enough to the fire to use your fire extinguisher without getting your eyebrows singed. I was always known for having long eyelashes, and I thought I could hear them sizzle as they brushed against my safety glasses.
That’s when they pulled the fire hose out of the fire box that was there next to the fire hydrant. All over the plant grounds there were these red boxes. They are lined up alongside the long conveyor belt from the coal yard to the plant (about 1/2 mile). They were also lined up around the two silver painted million gallon number 2 Diesel tanks. They were just about everywhere you looked (come to think of it).
I remember Summer Goebel when she was a new plant engineer one time asked me when she had first arrived, “What are all those red boxes out there?” (she was pointing out the window of the Engineer’s office). I told her they each contained fire hose and a valve wrench to open up the fire hydrant. I neglected to add that they also provided great shade for all the Jack and Jill rabbits that inhabited the plant grounds, which doubled as a wild life preserve.
So, we were going to use the fire hose! That sounded like more fun. That is until the one guy said to the other guy (more using hand and face signals — like putting his thumb up and winking) “open ‘er up” — so, he was using “slang” hand and face signals…
That’s when the real training began. First of all, we all backed up because as the flames grew on their structure, the heat literally talked directly to your legs and magically told them…. “back up, or else…” so, now that we were standing a good 50 feet away from the fire, we lined up in a row on the fire hose.
4 of us. Four hefty Brawny Power Plant men… (well, 3 hefty brawny power plant men, and one scrawny little runt of a summer help who actually thought he could be measured alongside them), Isn’t that a bit much for this one 4 inch fire hose? (or was it just 3 inches?). There were two hoses actually being used. One to create a wide barrier of water to protect us from the heat, and another hose to shoot water through the barrier into the fire.
A couple of guys manned the large roll around fire extinguisher. Here is an actual picture of the OSU Training Service training a group of employees at a work site to fight fires to give you a picture of what we faced:
Notice the two different types of sprays in the picture. one very wide spray and a narrow spray.
Like I said, these guys aren’t called the best Fire Trainers because they have pretty pamphlets. so, the first time I slipped in the mud, I thought… hmm… I suppose the rainsuit would have kept all that mud from coming into contact with my jeans, and my shirt and my ego.
Well, the most fascinating thing was that we could walk up real close to this intense fire and the wide spray of water sheltered us from the heat.
Then with the large fire extinguisher on wheels, you could open it up on the fire by standing behind this barrier and shoot the chemicals right through the water onto the fire, and it would quickly and incredibly put out that tremendous fire when it was done right. The other fire hose that was spraying through the barrier of water was used to cool everything down so that the fire didn’t spring right back up. the water wasn’t going to put out an oil fire.
Anyway, not long after our first of many fire fighting training sessions that we had throughout the years, the night that we were actually fighting the dragon in the boiler (See the Post, “Where do Knights of the Past go to Fight Dragons Today“), the Control Room came over the gray phone (PA system) saying that there was a fire on the turbine room floor.
A bunch of power plant he-men dropped the lance they were using to pierce the dragon and ran off to fight the fire. It turned out to be a barrel full of oily rags that had spontaneously combusted. The fire refused to go out for a long time. It kept re-igniting until the contents had completely burned up.
I remained in the bottom ash area as I was still reeling from the steaming hot water that had been spewed all over me. A little while later the men were back ready to grab the lance and go back to work on the boiler around 10pm (this after a full day of coal cleanup from 8am that morning).
The one important topic that they ingrained into our minds while we were taking the training was that you have to know when the fire is too big to fight. We had learned what our equipment could do and what it couldn’t do. So, we had the knowledge to realize that if the fire is too big, then it is time to get out of there and call the professionals. The only problem was that the nearest professionals were about 20 minutes away. A lot can burn down in that amount of time…. but that is a story for another time. I see the grin on the power plant men’s faces. They know what I am talking about. (For more see the post: Destruction of a Power Plant God).
