VersaLadder Collapse Due to False-Locked Hinge

MASE Product Failure Injury Report

Product involved: VersaLadder Articulating Aluminum Ladder

What happened:  Person using Versaladder in straight ladder configuration.  The ladder collapsed when the user was part way up the ladder due to a hinge collapsing, sending the user falling to the ground.

Injuries: Back and head injuries

Recommendations:  Use a hinge lock with a uniform cross section to prevent partial engagement of lock, protect hinge to prevent increased friction in joint due to rust, dirt, and debris.  Also more intuitive locking mechanisms may help increase proper use.

OSHA/Standard violations?: No
