A 32 year-old male electrician died when crushed between the guardrails of a workbasket and the face of an industrial neon-fluorescent sign. The decedent was changing the fluorescent light bulbs in the sign. To accomplish this task, the decedent used a truck-mounted hydraulic/electric crane workbasket with joystick type controls mounted on the yoke of the basket. After the decedent positioned the workbasket at the base of the sign, he swung the sign face up from the bottom over his head to gain access to the fluorescent tubes. As the decedent pushed the sign face upward over his head trying to wedge a piece of PVC pipe in place, he inadvertently forced the panel against the workbasket controls, activating them, forcing the workbasket into the sign. As the workbasket came forward into the sign, it jammed the sign face into the controls, preventing the controls from returning to a neutral position. The decedent's co-worker, working on the opposite side of the sign, tried to rescue the decedent by lifting the panel, activating the main controls, and cutting away the sign face, but was unsuccessful. The CA/FACE investigator determined that, in order to prevent future occurrences, employers, as part of their Injury and Illness Prevention Program (IIPP) should: 1. Prepare a written job hazard analysis (JHA) for job assignments that have multiple ways to complete the job, to determine the safest procedures to follow. 2. Protect workbasket controls against unexpected activation 3. Develop rescue procedures that show how to override the auxiliary controls when someone is in the workbasket.
