What I did today was set machine #9 on fire while modifying a guard with a cut off wheel.
I would have to agree that I have become entirely too complacent using cut off wheel in the plant. Our major product is fiberglass cloth, and as you know fiberglass doesn't burn.
Until it DOES.
I managed to send sparks under the gearbox which was covered in oil soaked fiberglass bits. It was dam impressive how quickly they built up to a very healthy flame.
We got it out pretty quick, just a couple wires singed and three damaged air lines.
A bad mistake with good outcomes.
Lessons learned are many.
#1. hot work permit (with fire watch) needed for cutting discs. Be aware of where the sparks are going.
#2. Know where the fire extinguishers are. After the fire breaks out is too late to figure out where the closest one is.
#3. Work can be moved to the metal shop or other methods used such as a jig saw.
In Afghanistan, complacency was my ranger tabbed squad leader's greatest nemesis.
Work safe.
