Blind To The Potential Consequences
As well as being a design engineer, I was considered a Lead Auditor by my previous employer. As such, I would be asked to go to their other sites and carry out Health, Safety, and Environmental audits. Most of the time, all was fine and dandy, but there were a couple of Not Always Working-worthy moments. Both involved heat treatment plants, but not the one I wrote about in this story.
The first one was when I saw someone not wearing safety glasses in the plant in an area that was clearly signposted as requiring safety glasses. I asked him about it; as a permanent member of staff in the area, his training would have required him to know the required PPE [personal protective equipment].
Worker: “Oh, these are safety glasses. I just removed the shields as they got in the way.”
I had to point out that this was not just breaking company policy but breaking the law.
The second tale happened at a different site. Heat treatment isn’t just a matter of heating and cooling of metals. Well, it is, but it’s how you heat and cool them down that matters. Did you know that to give some steels a very hard surface, you heat them in a bath of potassium cyanide?
As you can imagine, you have to be very careful about how you store these chemicals. My knowledge of chemistry isn’t that great, but I have read enough Agatha Christie to know that cyanide salts are very dangerous.
Something else I read was a note on the sacks of potassium cyanide stored on pallets in the chemical storage area — that these must not be stored next to acids. This is because acids plus cyanide salts will create hydrogen cyanide gas, which is quite high up on the list of Chemicals To Run Away From Really Fast.
Stored next to these sacks were acids.
I raised this as a major non-conformance, which in these sorts of audits is the highest level: basically, it’s only luck that’s stopping you from having a major incident. I made sure the heat treatment manager and the site health and safety manager were aware, and I made it very clear in my audit report, of which they both got copies.
A year later, I was back at that heat treatment plant. The heat treatment manager was very keen to show me the improvements they had made since the last audit. No longer were these dangerous chemicals stored on pallets in the middle of the chemical store room; the room now contained several special heavy-duty lockable chemical storage safes. This added an extra level of security instead of just relying on the lock to the chemical storage room.
He opened one safe to show me what was inside: several sacks of potassium cyanide salts… right next to the same acids as before.
