When I used to work for a tank fabrication shop, I was using the grinder on some welds and was kneeling on the floorset the grinder down and some idiot sweeping the floor yanked on it with the broom and somehow it went on and nailed me in the knee..I had a nice deep cut about 3 inches long and down to my knee cap.. needless to say I yanked the cord out and threw the grinder at the guy sweeping last time I ver used the shops junk electric tools..
he was pissed because he screwed something up and the shop foreman put him on broom duty and was knocking everything out of his way with the broom instead of going around or stopping to move it.. being I was working two feet from where he was..ya think he woulda swept somewhere that wasnt having work being done .. the guy was actually fired a week later because they stuck him on a tank they had on its side to cut the legs off of itand he cut through it and instead of dropping t straight down or placing it next to him until he was done the other side and bringing them down off the tank together he tossed it over his shoulder on the other side of the tank ..just happen to be right where the foreman parked his brand new dodge truck..and it didnt look to nice with a 3 foot metal stand sticking out the windshield..
He kinda stayed away from me from that point on..matter a fact I saw him about a month ago in a wawa market and he did a fast about face to the back of the store.. 8)and its been a good 13 years since I worked there..and a good 15 since he did..
