NCCCO Emergency Procedures & Accident Prevention 2

Question 1

A crane's wire rope breaks during a lift. What is the operator's immediate priority?

Accepted Answer

Sound the alarm, ensure personnel are clear, and secure the crane

Answer

Immediately alert all personnel in the area, ensure no one approaches the fallen load, secure the crane, and report the incident. Investigation and rope inspection come after the area is safe.

Question 2

What should happen if a crane contacts a power line?

Accepted Answer

The operator should stay in the cab, try to move the crane away, and warn others to stay clear

Answer

The cab provides electrical protection. The operator should try to swing or drive away from the line. If unable to move, stay in the cab. If forced to exit, jump clear without touching the crane and ground simultaneously.

Question 3

What is the 'crane operator's stop work authority'?

Accepted Answer

The authority to stop any operation they believe is unsafe, regardless of who ordered it

Answer

OSHA and industry standards give operators the right and responsibility to stop work if conditions become unsafe. This authority cannot be overridden by supervisors or site managers.

Question 4

During a critical pick, what additional safety measures should be in place?

Accepted Answer

A detailed lift plan, additional personnel for spotting, pre-lift meeting, and contingency procedures

Answer

Critical lifts (near capacity, over personnel, with hazardous loads) require a written lift plan, engineering review, pre-lift safety meeting, dedicated signal persons, and documented contingency procedures.

Question 5

What is the first step in responding to a crane tip-over or collapse?

Accepted Answer

Evacuate the area, call emergency services, account for all personnel, and secure the scene

Answer

Immediate actions: evacuate the area to prevent additional injuries, call 911, account for all personnel who were in or near the work zone, and secure the scene to prevent further incidents.
