PENNSYLVANIA WAS ATTEMPTING TO PERFORM
UNAUTHORIZED ADJUSTMENTS ON AN ELEVATED WORK
PLATFORM SUSPENSION SYSTEM. A SCAFFOLDING
SUPPORT CABLE SLIPPED CAUSING THE PLATFORM TO
SHIFT. THE EMPLOYEE PLUNGED 364 FEET RESULTING IN
INSTANTLY FATAL INJURIES.

CITATION: FAILURE TO PROVIDE ADEQUATE TRAINING.
FAILURE TO PROPERLY MAINTAIN SYSTEM.
