When is a written rigging plan required according to OSHA standards?

A written rigging plan is required when conducting lifts over 75% of the crane's capacity or for any critical lifts. This requirement is established to ensure safety by thoroughly evaluating the lift's complexity and potential hazards. Such a plan provides detailed descriptions of the rigging setups, load weights, and lifting techniques that will be used, ensuring that all team members are aware of the procedures and safety protocols necessary to perform the lift correctly and safely.

Lifts that fall under this requirement typically present greater risks due to the heavyweight being lifted or the nature of the load, which may require additional attention to load stability, structural integrity, and other critical factors. Having a formal plan helps minimize risks and provides a structured approach to the lift, enhancing overall safety.

In contrast, the other scenarios such as lifts that are under a specific weight, all outdoor lifts, or all lifts do not match the criteria set forth by OSHA, which emphasizes the need for written plans specifically in higher-risk situations. This distinction is crucial for maintaining workplace safety and complying with regulatory standards.
