I suppose when you are a Plant Manager, the last person you want to see at your Power Plant doorstep is the OSHA Man! That’s exactly what happened on Thursday, March 10, 1994 at the Coal-fired Power Plant in North Central Oklahoma. He was not paying a social call. He was there to conduct an investigation. One in which I was heavily involved.
In my post from last week, “Tragedy Occurs During Power Plant Safety Meeting” I described a near death accident where a contract worker was engulfed in fly ash in a precipitator hopper. The accident was all over the 5 o’clock news in Oklahoma City. The press was there when the Life Flight helicopter arrived at the hospital where they interviewed the flight crew. The OSHA office in the Federal building a few blocks from the Electric Company’s Corporate Headquarters had quickly assigned someone to the case. Armed with all the authority he needed, he began a full investigation of the accident.
The day before Gerald Young, (the OSHA Man) arrived, I had done some investigation myself into the accident. I was trying to figure out exactly what had happened. Why had someone who thought that he had emptied out a hopper so much so that he climbed inside, had suddenly become instantly engulfed in ash? Where did this large volume of ash come from, and why did it decide to suddenly break loose and fill the hopper at the particular moment when James Vickers had decided to climb into the hopper?
Larry Kuennan, the lead engineer had asked me to show him the hopper from the inside of the Precipitator, so he could have an idea of what took place. I told him he needed to put on a fly ash suit and a full face respirator in order to go into the precipitator. After we were all suited up, I took him on a tour of the inside. A sight few people have had the chance to experience. I could write an entire post just about the experience…. Oh…. maybe I already have. See “Moon Walk in a Power Plant Precipitator”
The hopper we needed to investigate was not at the edge, so, we had to squeeze our way around a few beams in order to see the hopper where the accident took place. When we arrived, I explained that when I had first inspected the precipitator, I had found that the ash had piled up five foot above the bottom of the plates because the feeder wasn’t feeding properly. So, I had figured that when they were vacuuming out the hopper, the ash that was lodged between the plates (that were 9 inches apart) must have still been there when James climbed into the hopper. Something had caused the ash to give way all at once.
Larry and I climbed down between the hoppers where we could see the bottle racks underneath the plates. The bottles are 30 pound anchors in the shape of the old style milk bottles. They are used to keep the tension on the wires, which are the electrodes that are normally charged with up to 45,000 volts of electricity when the precipitator is online.
When we sat down to look at the four bottle racks, I noticed right away that one row of bottles was about a foot and a half lower than the rest of the bottle racks. This didn’t make sense to me at first. I couldn’t think of anyway that 176 wires and bottles would be lower than the rest of the wires in the hopper. It was a paradox that took a while to soak in.
When we left, Larry Kuennen made a statement I will never forget. He said, “Until now, I thought that Plant Electricians did nothing but twist wires together. I never thought they worked on things like this.” I replied, “We work on anything that has a wire connected to it. That includes almost everything in the plant.” He replied, “Well, I have a new appreciation for Plant Electricians.”
It wasn’t until I returned to the electric shop and heard Scott Hubbard’s recount of the accident (again). Scott and his crew was working on the roof of the precipitator when the accident happened. He said that when the accident happened he heard a loud bang. Sort of like an explosion. I told him what I had found inside the precipitator. This could only mean one thing…. An electric insulator on the roof of the precipitator that held up the wires on that bottle rack had broken. When that happened, it fell the foot and half causing all the ash that had been lodged between the plates to be jolted loose, engulfing James Vickers who had just climbed in the hopper below.
After lunch, Scott went up on the roof and opened the portal on the tension house that housed the insulator that held up that row of wires. Sure enough. The three foot by 3 inch diameter ceramic insulator had broken. Something that had never happened at the plant up to that point. A tremendous load must have been put on this insulator, or it must have been defective in order to just break. These insulators are designed to hold up to 10,000 pounds of weight. the weight of the bottles and wires altogether weighed about 6,000 pounds. This meant that about 4,000 pounds of ash was pressing down from the ash above in order for it to just pull apart.
There was only one person that the OSHA man Jerry wanted to speak to when he arrived at the plant (other than to arrange things). That was me. I was the acting foreman in charge of the operations in, on and below the precipitator when the accident happened. I was also just a regular hourly employee, not so “beholden” to the company that I would participate in any kind of “cover-up”.
The first thing OSHA Jerry wanted to see was the inside of the precipitator. So, I procured a respirator for him, and we climbed up to the landing where one enters the precipitator through side doors. The first thing he did when he arrived at the door was take out a measuring tape to measure the height of the door.
I hadn’t thought about it until that moment, but a new set of OSHA regulations had a new set of Confined Space regulations 1910.146 that dealt specifically with confined spaces. It had gone into effect on April 15, 1993. Here we were almost a year later. I had always treated the precipitator as a confined space, so I had always checked the air quality before I entered it.
So, I asked OSHA Jerry why he measured the size of the door. He said, he was checking if the entrance was “restricted” or “limited”. This was the requirement of a Confined space as stated in OSHA regulation 1910.146. I asked him how small does an entrance have to be to be restricted? He said, “Well. That’s not clearly defined. We could enter the precipitator by bending over and stepping in.
That was the first time I thought that maybe the precipitator itself may not really fit into the strict definition of a confined space. The hoppers do for sure, but does the precipitator? Hmm…. I wondered…. I still do come to think of it. The hoppers were definitely confined spaces by definition… “any space with converging walls, such as a hopper…..”
Oh. I forgot to describe OSHA Jerry. He reminded me a little of the guy a sidekick in Cheers named Paul Willson:
Actually, he looked so much like him that I thought of him right away.
When we were done inspecting the precipitator, we returned to the front office where we went to Tom Gibson’s (our Electric Supervisor) office. He closed the door and locked it. And he began to interview me by explaining that anything that was said in this room would be held in confidence. He explained that I could speak freely and that the Electric Company could do nothing to me for telling him the truth.
I thought… Ok…. um…. I have always been known for speaking my mind, so he wasn’t going to hear anything that I would personally tell the Plant Manager, Ron Kilman to his face. Just ask Ron. I’m sure he would agree that I was pretty open about anything that popped into my mind.
He asked me if I had been trained how in the OSHA Confined Space regulations. I responded by saying that we had a class in it one day where we went over our new confined space requirements. That consisted of reading the company policy. I knew that I needed to have a hole watch, and I needed to check the air before I went into a confined space.
We checked to make sure there was 20.9% oxygen, that there was less than 10 parts per million Carbon Monoxide, less than 5 parts per million H2S (Hydrogen Sulfide) and that there was less than 5% explosive vapors. OSHA Jack wrote everything down.
Actually, while I was talking, Jerry asked me to pause often because he was writing everything I said word-for-word on a yellow notepad what I was saying.
While we were talking, I asked him a few questions also. I asked Jack how he decided to work for OSHA. Where he had come from (Kansas. Wichita, I think). How long he had been working for OSHA. Did he enjoy his job….. At times, I could get him to digress and tell me a story about his life.
As we continued with our interview over this grave accident that almost resulted in the loss of someone’s life, I was busy making a new friend. By the time he had asked me everything he needed to know, I knew all about how he had grown up in Kansas, and how he had gone from job-to-job until he had ended up in front of me… interviewing me.
When we had finished the interview, he explained to me that this was an official document that contained all the answers to the questions he had asked me. He said that this would be private and that the Electric Company would not be able to ever see what I said unless I wanted them to see it. I asked him if I could show it to them. He said he would give me a copy of it, and I could do whatever I wanted with it. He asked me to sign it. I did.
I took Jerry to the copy machine in the front office where he made copies for me. When he handed them to me, I shook his hand. I told him I enjoyed talking to him. I also told him that I wished him well. I showed him to the elevator, and he left the plant. I made a copy of the papers that I had signed and went directly to the plant manager Ron Kilman’s office and gave him a copy of the document I had signed.
Ron asked me how it went. I told him that it went fine. Here is everything we talked about. I had nothing to hide. It did amaze me that OSHA Jack thought I might want to “spill the beans” about something as if we were treated like peons where the King had total rule. — I guess he didn’t know that Eldon Waugh had retired in 1987.
From there, I went to Bill Bennett’s office. Bill Bennett was our A Foreman. His office was across the hall from Tom Gibson’s office where I had been interviewed for the previous 3 hours. — Yeah. 3 hours. OSHA Jack didn’t know Shorthand.
Bill asked me how the interview went. I said it went fine. He said that Ron and Ben Brandt had been worried about me because the interview had lasted so long. Bill said he told them, “Don’t worry about Kevin. He probably has this guy wrapped around his little finger. He’s probably using his ‘psychology’ on him” I always loved Bill with all my heart. He knew me too well. I told Bill that I knew OSHA Jack’s life story by the time we were done. Bill smiled…. just like this:
I smiled back at Bill. I returned to the Electric Shop to continue with Unit 1 Overhaul. After all. That was my “real” job. I put on my fly ash suit, my full face respirator, and my rubber boots and returned to the innards of the precipitator to continue where I had left off. I had a lot to think about as I scanned the Precipitator plates and wires in the dark with my flashlight safely strapped around my neck.
