Propane dispenser electrical systems must conform to NFPA 58 for ignition source control and those of ______ for hazardous

• A. NFPA 58
• B. NFPA 13
• C. NFPA 30
• D. NFPA 70

Answer: (D)

Propane dispenser safety hinges on both controlling ignition sources and protecting electrical equipment in flammable-vapor areas. NFPA 58 covers ignition source control for LPG systems, reducing the chances of sparks or heat starting a fire at the dispenser. For the electrical side in hazardous locations, the applicable standard is NFPA 70, the National Electrical Code, which specifies how electrical installations must be designed and protected when vapors or flammable liquids could be present. NFPA 13 and NFPA 30 address sprinkler systems and general flammable liquids handling, respectively, and do not provide the electrical hazardous-location requirements.
