Which American National Standard outlines safety in welding?

• A. ISO 9001
• B. ANSI Z49.1
• C. ASME IX
• D. AWS D1.1

Answer: (B)

Safety practices in welding are governed in the U.S. by a dedicated standard that spells out how to perform welding, cutting, and allied processes safely. ANSI Z49.1, titled Safety in Welding, Cutting, and Allied Processes, is the reference you turn to for general safety requirements. It covers essential topics like personal protective equipment, protection from fumes and gases, ventilation, electrical safety, fire prevention and protection, safe handling of gases, and maintaining a safe work area. Because it focuses specifically on the hazards and safe practices of welding operations, it serves as the primary safety guide for shops and job sites.

Other standards have different primary purposes. ISO 9001, for example, is about quality management systems and does not provide welding-specific safety guidelines. ASME IX is about qualification of welders and welding procedures for pressure-retaining components, with safety tied to ability and compliance in those contexts rather than universal safety practices. AWS D1.1 covers structural welding criteria and workmanship, which includes safety considerations but not the broad, general safety framework that Z49.1 provides. Therefore ANSI Z49.1 is the standard that outlines safety in welding.
