Industrial Accident:
I used to work as a Boiler Plant Technician. The theory of a closed steam heating plant is that after the steam goes into the tennent's radiators (this was a heating plant for a public housing project; some 3000+ apartments), it is cooled, then condenses back into air and water. This water is reclaimed through a series of pumps, then stored into a large take for re-using as water for steam.
It's loaded with chemicals to keep rust out, make it less viscous, etc. One day, I was working with this old-timer (sloppy worker he was) on one of the giant condensate pumps, replacing the motor. We closed the shut-off valve feeding the pump tank, located in a pit about 10' below the floor and were trying to remove the motor when it happened;
... I couldn't remove the motor from the pump impeller housing, even after removing all the bolts. I was given the brilliant advice to kick the motor to free it from the rusty housing, which I did, since I only had ~3 months on the job and 'didn't know anything' ... then KABLOOOEY!! The pressurized sub-boiling water exploded all over my left leg, from my ankle to nearly my goodie pack ... turns out the shut-off valve was defective and didn't shut off anything ... I didn't even climb the ladder to escape from the pit; I think I jumped straight up, ran to the adjacent compacter room, stripped off what was left of my pants, and flushed my leg with water from a hose.
I spent 10 days in the hospital with 2nd and 3rd degree burns, and got addicted to morphine. Oh, and I got a settlement from the city .. not much, but it helped out.
The End.
