Which ASME standard relates to rigging hardware?

The correct choice is C, as ASME B30.26 specifically addresses "Rigging Hardware." This standard provides guidelines and requirements for the use of various rigging components, including hooks, shackles, links, rings, and other hardware used in lifting operations. It covers aspects such as design, materials, inspection, testing, and maintenance, which are crucial for ensuring the safety and reliability of rigging operations.

By adhering to ASME B30.26, operators and riggers can ensure that the hardware they use meets acceptable safety standards and performance criteria, thereby reducing the risk of accidents during lifting activities. This standard is essential for anyone involved in crane operations, ensuring that all rigging hardware is suitable for the loads being lifted and is properly maintained.

The other standards mentioned focus on different aspects of crane and hoisting equipment. For instance, ASME B30.15 relates to "Personnel Lifting System," ASME B30.5 pertains to "Mobile and Locomotive Cranes," and ASME B30.9 covers "Slings." Each of these standards addresses specific equipment or procedures but does not concentrate on rigging hardware as directly as ASME B30.26 does.
