During deactivation and decommission, two radiologically contaminated roof vents were removed from an unmanned warehouse by suspending them from the handrail of an aerial lift. The vents had been appropriately packaged upon removal to prevent the spread of contamination. However, using the hand rails for suspending a load was not in compliance with the manufacturers operating manual and use of the aerial lift for this purpose was not discussed during the pre-evolution briefing.

Lessons Learned: Deviation from the planned evolution created non-evaluated hazards and could have resulted in adverse consequences. Equipment operators must be aware of intended applications for equipment, as defined in the manufacturers operating manual, and must operate equipment only as intended. When field conditions change, the subject matter experts and management should be informed/consulted. Communication channels between field work teams, management, and subject matter experts must be open to ensure new hazards are properly evaluated.
