The National Fire Protection Association (NFPA) is the authority on fire, electrical and building safety. NFPA’s 300 codes and standards influence every building, process, service, design, and installation in the United States.
NFPA-58 is the code of liquefied petroleum gas. This code applies to the storage, handling, transportation, and use of LP-Gas.
Four specific NFPA-58 sections of code that all propane suppliers utilize on a daily basis:
Container Connections and Appurtenances
The supply source shall be correctly matched with the intended equipment.
• It is important to know which form of propane (liquid or vapor) your appliance or system uses.
• Your tank shall be properly marked and fitted with the correct valves. Contact your propane supplier for the necessary valves.
Container Separation Distances
Tanks and cylinders shall be properly located to better ensure your safety and to meet state laws.
• The size and type of container determines where it can be placed on your property.
• Contact your propane supplier to discuss placement options.
• Once the proper location has been determined and the container has been placed, don’t move it.
Sources of ignition shall be turned off during transfer operations, while connections or disconnections are made, or while LP-Gas is being vented to the atmosphere.
All ignition sources shall be turned off during transfer operations.
• Less than 15 ft. - All sources of ignition shall be shut down.
• Less than 25 ft. - Smoking, open flame, electric tools, and extension lights are not allowed.
• Less than 50 ft. - Crop dryers and air-moving equipment shall be shut down.
• Additionally, materials heated above 920 degrees F must be cooled before transfer operations begin.
Filling and Evacuating of Containers
Transferring LP-Gas to and from a container shall be accomplished only by qualified persons trained in proper handling and operating procedures.
• Contact your propane supplier when process is required.
• Containers shall be filled only after determination that they comply with the design, fabrication, inspection, marking and re-qualification provisions of NFPA-58.
• Only propane may be placed in the container. Never place propane in a NH3 container without proper cleaning and valve replacement.
