Which agency sets the standards for gas appliance safety in the U.S.?

The American National Standards Institute (ANSI) plays a crucial role in setting safety standards for gas appliances in the U.S. This organization coordinates the development of voluntary consensus standards for a variety of products and services, including gas appliances. ANSI establishes guidelines that address safety, design, performance, and testing procedures, ensuring that appliances meet minimum safety requirements to protect consumers.

Standards developed under ANSI are often referenced in various safety codes and regulations, including those developed by other organizations, which may focus on specific aspects of gas usage or fire safety. ANSI's involvement in these standards helps to promote uniformity and reliability across the industry.

The other organizations mentioned have important functions in their respective areas. The International Code Council (ICC) develops and publishes building codes but does not specifically create standards for gas appliance safety. The Occupational Safety and Health Administration (OSHA) sets and enforces workplace safety and health regulations, while the National Fire Protection Association (NFPA) focuses on fire safety codes, which can include aspects relevant to gas appliances but does not directly set appliance safety standards themselves.
