What happened here?

“These safety glasses make me look stupid. ” And being blinded by a grinder disk doesn’t?

Safety glasses $ 9. 00 Eyesight --- priceless

“But I only had a little more to grind”

“It’s only a drill, what’s the big deal? ”

One of our experienced maintenance workers was using a large screw driver as a chisel and pry bar. The screw driver shaft snapped as he was using all his force and body weight to attempt to get the tip of the screw driver between a pump mount and it's concrete pad. You can see the results. 37 stitches, 4 lost work days, 25 restricted work days. 50% of accident in the shop are a result of hand tool misuse. Never use a tool for a job it’s not intended. Injuries cost everyone.
