ANSI Z49.1:2021 An American National Standard Safety in Welding Cutting and Allied Processes AWS American Welding Society ANSI Z49.1:2021 An American National Standard Approved by the American National Standards Institute July2 2021 Safety in Welding Cutting and Allied Processes Revises ANSI Z49.1:2012 Prepared by the Accredited Standards Committee Z49 Safety in Welding and Cutting Secretariat American Welding Society Abstract This standard covers all aspects of safety and health in the welding environment emphasizing oxygen gas and arc weld- ing processes with some coverage given to resistance and high energy beam welding brazing and soldering.It contains information on protection of personnel and the general area ventilation fire prevention and protection and confined spaces.A significant section is devoted to precautionary information showing examples and an extensive bibliography is included. AWS American Welding Society ANSI Z49.1:2021 American National Standard Approval of an American National Standard requires review by ANSI that the requirements for due process consensus and other criteria for approval have been met by the standards developer. Consensus is established when in the judgment of the ANSI Board of Standards Review substantial agreement has been reached by directly and materially affected interests.Substantial agreement means much more than a simple majority but not necessarily unanimity.Consensus requires that all views and objections be considered and that a concerted effort be made toward their resolution.
