Which agency primarily regulates gas safety in the United States?

The agency that primarily regulates gas safety in the United States is the National Fire Protection Association. This organization plays a critical role in developing and promoting codes and standards related to fire safety, including regulations for the safe use of gas. They focus on preventing fires and hazardous conditions associated with flammable gases, ensuring regulated handling and storage practices to protect both the public and the environment.

The Environmental Protection Agency mainly oversees environmental protection, rather than specific gas safety regulations. The Nuclear Regulatory Commission focuses on nuclear safety and regulation and is unrelated to gas safety. The Occupational Safety and Health Administration is responsible for ensuring workplace safety across various industries, but it does not specifically regulate gas safety standards like the National Fire Protection Association does. Thus, the emphasis on gas safety clearly aligns with the role of the National Fire Protection Association in establishing guidelines and standards for safe practices.
