What requirements must all welding and cutting on hoisting equipment comply with?

The requirements for welding and cutting on hoisting equipment must align with specific standards that ensure safety and quality. The correct choice, which references AWS (American Welding Society) and ASME (American Society of Mechanical Engineers) codes, underlines the importance of adhering to established industry standards. These codes provide comprehensive guidelines on welding practices, including qualification of welders, types of welding processes permitted, and inspection criteria. Compliance with these standards helps to ensure that any welding performed contributes to the structural integrity and safety of the hoisting equipment.

The other options, while important in their own contexts, do not specifically govern the welding and cutting processes in a way that is as directly relevant as the AWS and ASME codes. OSHA guidelines focus on workplace safety and health regulations, which may encompass welding safety but do not offer the level of technical detail needed for compliance in the welding processes themselves. Local fire codes are primarily concerned with fire safety practices but do not delve into the specifics of welding techniques and standards. Manufacturer specifications, although vital for equipment maintenance and operations, may not cover the broader welding and cutting practices pertaining to industry standards like AWS and ASME.
