Hand Tool Injury (KV10)


What Happened?

A lost workday accident occurred while rigging up equipment prior to a larger job. The Injured Person (IP) was using a 24" iron pipe wrench to connect two pieces of equipment needed for the upcoming work. Another employee was holding the backup wrench during the tightening of the tool, when the adjustable ring broke, causing the IP to strike himself in the right eye.  Proper working procedures were in place and no excess pressure was applied to the tool.

Contributing Factors

Equipment was weakened due to excessive corrosion and wear on the threads.

The IPs body positioning did not consider the worst case scenario.

What Can We Learn?


Peer Checking, Self Checking and a Questioning Attitude could all have helped the IP identify the hazard and associated risk of working with equipment that has been corroded. 

Our Questioning Attitude also drives us to ask “What is the best body positioning for the task?”


Overconfidence by the IP may have led to his failure to inspect his equipment and also may have hindered his Questioning Attitude.
