Multiple cranes are operating on the same job site. What hazard must be addressed?
Answer: Potential for crane-to-crane contact, overlapping swing radiuses, and coordination of lifts to prevent collisions
Multi-crane sites require coordination plans addressing anti-collision measures, communication protocols, defined operating zones, and prohibited swing areas to prevent boom or load contact between cranes.
What pedestrian hazard exists near crane operations?
Answer: Falling objects, swing radius of crane body and counterweight, moving loads, and wire rope under tension
Pedestrians face multiple hazards: objects dropped from height, struck by swinging crane parts, contact with moving loads, and snapping wire rope. Barricades and spotters create exclusion zones.
A construction site has multiple stories. What additional risk assessment is needed for crane operations?
Answer: Assessment of loads passing over occupied floors, falling object protection, communication between floors, and emergency evacuation plans
Multi-story sites require assessment of loads traveling over occupied areas, installation of overhead protection, floor-to-floor communication systems, and clear evacuation procedures for each level.
What is the hazard of operating a crane near a body of water?
Answer: Soft/unstable ground near the waterline, drowning risk for personnel, and potential for the crane to slide into the water
Waterside operations present soft/saturated soils, erosion risk, drowning hazards, reduced ground bearing capacity, and potential for the crane to slide toward the water if the bank gives way.
How should hazardous material loads be handled differently in risk assessment?
Answer: Additional containment, spill response plans, specialized rigging, restricted work zones, and emergency procedures specific to the material
Hazardous material lifts require additional planning: specialized rigging to prevent spills, containment measures, emergency response equipment, restricted access zones, and communication with hazmat teams.
During a pre-lift risk assessment, who should participate?
Answer: The operator, rigger, signal person, site supervisor, and any affected workers — everyone involved in or impacted by the lift
Everyone involved in or affected by the lift should participate in the risk assessment and pre-lift meeting. This ensures all perspectives on hazards are considered and everyone understands their role.
