Stop in for a cup of coffee

I had a fire at work a week ago. Was resurfacing a rubber print roller on the grinder. It was damaged so was cutting it down way more than normal. It automatically hits a return at each pass, so I was away from it when it started. Knocked flames out with one shot of dry chem. Started to walk away and realized the exhaust fan was on fire above it, Hit that with a shot and it went out. Got out of the room. Ended up having to take the exhaust duct down cause it was full of smoldering rubber accumulation. Shop still stinks a little...
