Davidson Aluminum Stepladder Injury

MASE Product Failure Injury Report

Product involved: Davidson G 527-06 Aluminum Stepladder

What happened:  Woman was applying tape to a wall she was painting.  She had ascended to the third step of the stepladder.  While she applied tape, the ladder became racked, and then failed as the ladder tipped over.

Recommendations: Increase stability of ladder by widening base of ladder.  The ladder could have been made stronger by increasing the thickness of the materials and by more appropriate bracing. Ladder cannot withstand dynamic forces.

OSHA/Standard violations?: No violations, although material was found to not meet minimum specifications.

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
