What must an operator do before moving a boom truck to a new location with the boom elevated?
Answer: Retract and lower the boom to the travel position
Booms must be fully retracted and lowered to the stowed travel position before driving to prevent tip-over from dynamic forces and clearance hazards.
During aerial lift operations, a ground-based crew member must:
Answer: Stay clear of the drop zone and maintain visual communication with the operator
Ground crew must stay out of the drop zone to avoid struck-by hazards and maintain sight lines and communication with the bucket operator.
What does 'rated work load' (RWL) on an aerial lift refer to?
Answer: The maximum combined weight of workers, tools, and materials the basket is designed to carry
Rated work load is the manufacturer's specified maximum combined weight capacity of the bucket, including occupants, tools, and materials.
An operator notices a hydraulic fluid leak under the truck before starting. The correct action is to:
Answer: Tag the unit out of service and report it for repair before use
Any hydraulic fluid leak must result in the unit being tagged out of service; operating a leaking lift risks sudden loss of function and catastrophic failure.
When positioning outriggers on soft ground, operators should:
Answer: Place outrigger pads under the pads to spread the load
Outrigger pads distribute the point load over a larger area of soft soil, preventing the outrigger foot from sinking and destabilizing the truck.
Which scenario represents an unsafe aerial lift practice under OSHA 1910.67?
Answer: Climbing out of the bucket onto a tree branch to work
OSHA prohibits climbing out of or leaning over the bucket guardrails; workers must remain inside the basket at all times during aerial lift operations.
What pre-operation check confirms the aerial lift's emergency lowering system is functional?
Answer: Activating the emergency descent from the ground controls and verifying slow, controlled lowering
The emergency lowering function should be tested from the ground controls before each shift to confirm the operator can be retrieved if they become incapacitated aloft.
