Nevada OSHA did an investigation, which is how we got access, but it was for enforcement purposes, not for any deep analysis. We tried to be objective, but
without subpoena power or government resources we couldn't dig as deep as we would have liked, and we always had in the back of our heads that we would use the report to push for better regs. We've written a lot of accident reports, but this is the only one
we ever published in full color with photos not just of the scene, but of the surrounding destruction.
Meanwhile the company reorganized, moved to Utah, and reopened non-union
If anyone would like a copy I'll try to get you one, but this was before we produced this stuff digitally, so it will have to be a scan. And I'm off work for
medical reasons until late May and our staff is a little stretched, so it may take a little time. Just email me.

There was never a formal, unbiased investigation such as now done by the CSB. The major investigations were done by various litigation teams. The total subrogation was $100M and the matter continued active
for about 4 years. It finally settled w/o going to a jury trial.
The litigation was divided into parts
Cause & Origin
Propagation in
Piles
Bins
Drums
There were other minor parts, such as why a large, HP natural gas line was directly under the plant footprint.
I led the Propagation in Drums portion. If my memory serves, I spent five days in deposition.
I have presented a paper on PEPCON at an ACS National Meeting many years ago. I have also discussed it in several venues globally and will be presenting it again in October in SoCal (if accepted) as part of
a presentation on the value of the CSB to current plant safety.
This was a real eye-opening incident. I happened to see it from the air as I was flying to NoCal. My wife saw the smoke from the Four Corners area where she was on a long distance bike ride. Over the years,
I have met many people impacted by the explosions. There was a guy who was watching from about 8 miles away from his roof- and was blown off. Busted hip and leg. There was an airline employee who was hit in the face by the front door to her home from the
large detonation. And many more.
On this anniversary of the incident, we should all pause to appreciate just how far we have come in plant safety, and look at today's headlines to realize how far we have to go.
Stay safe out there!

My union represented the PEPCON workers. Two of us flew out on the next flight to Las Vegas. Initial reports were that as many as a hundred workers were missing
and feared killed. When we changed planes in Chicago, the reports were that about 30 were "confirmed" dead. In Las Vegas we got a car, talked our way past the authorities, and drove into Henderson to the local union office. There we learned it was two. I think
we both burst into tears - grief for the two; relief for the 30.
The material was oxidizer - ammonium perchlorate - not fuel. But at high temperature it explosively recombines. For years the company had allowed it to permeate
asphalt pads and roadways, creating a severe fire hazard. My co-investigator had visited the plant a year before, and had written a scathing report, but there was no PSM standard then, and neither Nevada OSHA nor the local authorities took it seriously.
When the fire started it quickly knocked out the fire suppression system. At that point the end was inevitable. The workers evacuated the plant and got everybody
out of the building next door - a marshmallow factory. The two who remained were the plant manager, who I guess thought he was honor-bound to stay, and the company comptroller, who worked in the on-site corporate headquarters, was in a wheelchair, and was
overlooked by the other officials and staff. Most of the ammonium perchlorate was stored in aluminum tote bins on asphalt pads which burned hotly due to the embedded oxidizer. Those bins are what you see exploding in the video.
I assigned two people to the investigation, who spent several months in Henderson. We used the resulting accident report to lobby OSHA for a PSM standard, and
when that failed, we used it to lobby Congress, which mandated the OSHA standard and the EPA RMP program in the 1990 Clean Air Act Amendments. I'd like to think the report had a small part to play in that.

A colleague of mine was driving past the plant shortly after the fire broke out. He was not from the area and he thought to himself that something unusual was clearly going on there. Obviously, he couldn't assist and didn't stick around
to gawk. He drove on a few miles to his destination in Henderson several miles away. He got out of the car and was staring at the fire when the blast wave rolled into town. He reported that it "knocked me flat on my ass". Dang impressive and what a near
miss for him!

WHAT TO KNOW ABOUT PEPCON EXPLOSIONS 30 YEARS LATER
https://www.ktnv.com/news/what-to-know-about-pepcon-explosions-30-years-later
Tags: us_NV, industrial, follow-up, environmental
Thirty years ago on May 4, 1988, the Las Vegas valley was rocked by three massive explosions. A fire that started inside a building at Pacific Engineering and Production Corporation (PEPCO) in Henderson resulted in 3 explosions.
Here is a quick list of interesting facts about the incident:
1. PEPCON produced ammonium perchlorate, which is a chemical found in solid rocket fuel.
2. Because of the Challenger explosion in January 1986, there was a large amount of ammonium pechlorate at the plant at the time.
3. It was the largest domestic, non-nuclear explosion in recorded history at that time, according to NASA.
4. The explosions coule be felt 10 miles away. The two biggest blasts measured 3.0 and 3.5 on the Richter scale at observatories in California and Colorado.
