NFPA 58/2008 Liquefied Petroleum Gas Code
NFPA 58: Liquefied Petroleum Gas Code helps you protect homes, businesses and industrial settings from LP-Gas leaks and explosions.
NFPA 58: Liquefied Petroleum Gas Code is the industry benchmark for LP-Gas safety. The 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. Requirements encompass 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. Each Code edition incorporates new information about safety practices, reflecting the latest field experience and industry advances.
- The 2011 NFPA 58: Liquefied Petroleum Gas Code includes a major change that requires cathodic protection for underground tanks to guard against corrosion. This new rule helps preserve structural integrity, since corrosion creates pits or holes that left alone or ignored can lead to leaks, releasing propane into the ground. Other changes help make installations more secure, including a new prohibition against using former rail car tanks as they do not meet standards of the ASME Boiler and Pressure Vessel Code. Other new and revised requirements help ensure adequate training of people who install or handle propane tanks and piping materials.
- The 2008 NFPA 58: Liquefied Petroleum Gas Code adds regulations for pipeline systems of 10-100 users served from one propane tank, such as a mobile home park. This edition also presents new location requirements for patio heaters; a revised table of small container appurtenances; a new rule to require notification of trackside transfer from rail cars; and new coverage of elevated pressure propane systems (20 – 50 psi) used in cogeneration systems, microturbines, metal cutting and similar industrial operations. Clarified requirements for flexible connectors used as part of piping systems help users avoid errors.
- The 2004 NFPA 58: Liquefied Petroleum Gas Code reduces the risk of accidents and fires with added security measures for bulk sites and industrial plants that are intended to minimize unauthorized entry and tampering. Added criteria for hose inspection helps Code users identify signs of damage that would probably lead to leaks. Revised OPD valve requirements clarify the exemption concerning industrial truck and industrial welding and cutting cylinders, and a new safety provision for vehicle propane fuel tanks requires an automatic valve that’s open only when the vehicle key is in the “on” position.
