A worker on the ground is directing a blind lift via radio. The signal is lost mid-lift. What should the operator do?
Answer: Stop all crane movement and hold position until communication is restored
Loss of communication during a blind lift requires the operator to stop all movement and hold position until communication is re-established with the signal person.
When conducting a post-accident investigation involving a crane, which action should be taken FIRST?
Answer: Secure the accident scene and preserve evidence for investigation
Securing the accident scene and preserving evidence is the first priority to ensure an accurate investigation and comply with regulatory requirements.
What is the minimum distance a crane must maintain from an energized power line rated at 50–200 kV, when no electrical utility owner authorization is in place?
Answer: 20 feet
OSHA 1926.1408 requires a minimum 20-foot clearance from power lines rated 50–200 kV unless the utility owner has authorized a reduced clearance.
An operator observes that the crane's load moment indicator (LMI) is reading differently than the load chart for the current configuration. The operator should:
Answer: Stop the lift and have the LMI inspected before continuing
A discrepancy between the LMI and load chart indicates a potential malfunction; the operator must stop and have the device inspected by a qualified person.
During a lift, a rigger signals an emergency stop. After stopping, the operator notices smoke coming from the hoist motor. What is the correct next step?
Answer: Shut down the crane and use an alternative means to safely lower the load
The crane should be shut down and an alternative lowering method employed so the compromised hoist motor is not used with a suspended load.
Which scenario represents a near-miss that MUST be reported per best practices and many site safety programs?
Answer: A load that swung unexpectedly but stopped before striking a worker
A load that swings and nearly strikes a worker is a near-miss event that must be reported so the contributing hazards can be identified and corrected.
If a crane operator becomes aware that personnel are inside the swing radius of the crane during an active lift, the operator should:
Answer: Immediately stop all crane movement and wait until the area is clear
All crane movement must stop immediately when personnel are detected inside the swing radius until the area is confirmed clear.
