This article reminds me of an incident that happened when I was a teenager. My stepdad worked at a power plant and there was some small explosion and three people died. One of them was the father of a guy I knew from school. I had heard his head was crushed. It was very disturbing imagery and it has stuck with me since. I worry about my husband working in a dangerous job, too, but it seems generally a lot of guys working in these places aren't following safety rules and that's how the accidents happen.
