What should be done if a rigger identifies unsafe conditions before a lift?

When a rigger identifies unsafe conditions prior to a lift, the most appropriate action is to notify the supervisor and halt the operation. This approach prioritizes safety above all else. By halting the operation, it allows for a thorough assessment of the identified hazards, ensuring that risks are mitigated before any lifting takes place. Communication with the supervisor is crucial, as they can provide guidance, allocate resources, or implement changes to the lifting plan to address the unsafe conditions identified.

Proceeding with caution while documenting risks, as suggested in another option, may put workers at risk. It does not resolve the potential hazards and could lead to accidents or injuries. Similarly, adjusting the plan without informing others fails to ensure that all team members are aware of risks and modifications, which is vital for maintaining a safe work environment. The idea of doing nothing simply because the majority agrees undermines the responsibility of the rigger and the critical importance of safety protocols in lifting operations.
