Which agency regulates the safety of propane systems in the United States?

The National Fire Protection Association (NFPA) is the agency that regulates the safety of propane systems in the United States by creating codes and standards that govern their safe use and installation. The NFPA specifically develops and periodically updates the National Fuel Gas Code (NFPA 54) and the Liquefied Petroleum Gas Code (NFPA 58), which provide guidelines aimed at preventing hazards associated with propane systems, including proper installation, operation, and maintenance.

Ensuring safety through these standards helps to reduce risks associated with fires, explosions, and other hazards. While other agencies like the EPA, OSHA, and DOE play important roles in related areas such as environmental protection, workplace safety, and energy policy, the NFPA is specifically focused on fire safety and prevention in contexts that include the use of propane.
