What reference standard governs the storage of liquid propane gas?

The storage of liquid propane gas is governed by NFPA 58, which is the National Fire Protection Association standard specifically focused on liquefied petroleum gases, including propane. This standard provides comprehensive guidelines on the safe storage, handling, and use of propane to minimize fire hazards and ensure safety in both residential and commercial applications.

NFPA 58 covers key elements such as the design and construction of storage facilities, the installation of underground and aboveground tanks, and the necessary precautions to prevent accidents or leaks. The standard is essential for ensuring compliance with safety regulations and best practices in managing propane storage.

In contrast, while the other standards address different aspects of fire safety and electrical installations, they do not specifically pertain to propane storage. NFPA 54 deals with the installation of gas piping and appliances, NFPA 61 focuses on the prevention of fires and explosions from agricultural operations involving combustible dust, and NFPA 70 addresses electrical wiring and safety. Thus, NFPA 58 is the correct reference standard for propane gas storage.
