Liquefied petroleum gases (LP-Gases), as defined in this code (see 3.3.36), are gases at normal room temperature and atmospheric pressure. They liquefy under moderate pressure and readily vaporize upon release of the pressure. It is this property that permits the transportation and storage of LP-Gases in concentrated liquid form, although they normally are used in vapor form. For additional information on other properties of LP-Gases, see Annex B. Federal Regulations. Regulations of the U.S. Department of Transportation (DOT) are referenced throughout this code. Prior to April 1, 1967, these regulations were promulgated by the Interstate Commerce Commission (ICC). The Federal Hazardous Substances Act (15 U.S.C. 1261) requires cautionary labeling of refillable cylinders of liquefied petroleum gases distributed for consumer use. They are typically 40 lb (13 kg) and less and are used with outdoor cooking appliances, portable lamps, camp stoves, and heaters. The Federal Hazardous Substances Act is administered by the U.S. Consumer Product Safety Commission under regulations codified at 16 CFR 1500, Commercial Practices, Chapter 11, Consumer Product Safety Commission.NFPA 58: Liquefied Petroleum Gas Code provides minimum safety requirements for all liquefied petroleum gas (propane) installations, from small cylinders installed at residences to large bulk storage facilities that can exceed 100,000 gallons.The code includes minimum requirements for safe handling during LP gas transfer, including operator qualifications, maximum filling quantity in containers, and pre-transfer inspections to ensure containers are fit for continued service.This edition of NFPA 58 features some important changes, including:Bulk plant and industrial plant definitions have been updated to clearly identify storage threshold at greater than 4,000 gallons water capacity.
Container appurtenance requirements have been harmonized at 4,000 and less/greater than 4,000 gallons water capacity to better reflect container usage in the field.
Container and valves often must be protected from vehicular impact. A new definition has been added along with extensive annex material to describe vehicular barrier protection.
New requirements specify which personnel must be trained and in what topics.
Requirements have been added for tank heaters and updated for vaporizers.
Requirements have been added regarding corrosion protection for some underground piping systems.NFPA 58 also covers a number of safety requirements related to:Container construction
Piping design
Separation of containers from homes, stores, schools and other important buildings
Safe handling of liquefied petroleum gas during transfer between containers
