What type of rigging must assembly and disassembly personnel use when assembling boom extensions?

The correct choice is authorized rigging, as personnel involved in the assembly and disassembly of boom extensions must use rigging that meets specific standards and is verified for safety and reliability. Authorized rigging refers to equipment that is approved for the intended use and adheres to regulations and manufacturer specifications, ensuring the safety of personnel and the integrity of the lift.

Using authorized rigging helps prevent accidents and equipment failures, as it assures that the rigging has been appropriately designed and tested for the specific loads and conditions expected during the assembly and disassembly process. This is especially critical in operations involving boom extensions, where precise handling and stability are vital due to the dynamic loads and potential hazards involved.

General-purpose rigging, while useful in many scenarios, may not be suitable for the specific requirements of boom assembly and disassembly tasks. Temporary rigging refers to equipment that is used for short durations and might not have the same safety assurances as authorized types. Weight-rated rigging focuses on the load capacity, but without proper authorization, it may not meet other critical safety standards necessary for safe operations.
