I’ve been in those foundries. They are dangerous. I’ve seen those molten ladles. Nothing to mess around with.
I was working in my office outside the core department when we experienced a “pop” as they called it. Scared the crap out of me and shook the building. I’ve also watched them fill those ladles from the melters (we used medium frequency) and molten sparks fly everywhere. Since steel toe boots, helmets, safety glasses, and fire retardant coats were mandatory I’d stand aside and watch from time to time. Really is a fascinating process.
About 6 months after I left the company there was an explosion. 3 people lost their lives, and another paralyzed for life. Many burned or bones broken. Where the explosion happened was directly under my old office which wound up 2 stories under ground. One woman who lost her life was in the office next to mine. :(
“Official” determination was leaking natural gas, but I know for a fact it was the t-gas which leaked all the time. We all knew it, but let the officials say what they want. Place closed down and is now nothing but an eye sore.
