“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.
