Which published standard should be consulted to determine spacing and setbacks for propane tanks?

• A. ASME B&PVC
• B. DOT 49 CFR
• C. EPA
• D. NFPA 58

Answer: (D)

Spacing and setbacks for propane tanks are governed by NFPA 58, the LP-Gas Installation Code. This standard specifically addresses how LP-gas systems must be installed, including the minimum distances from buildings, property lines, openings, and sources of ignition, as well as other siting and safety considerations. It’s the reference that practitioners use to ensure tanks are placed in safe, accessible, and compliant locations.

The other standards don’t cover siting in the same way: ASME B&PVC deals with the design and construction of pressure vessels rather than where they can be located; DOT 49 CFR focuses on the transportation and handling of propane, not on installation setbacks; EPA governs environmental aspects but not installation spacing for propane storage.
