Updated to reflect the latest safety practices, field experience, and industry advances, the 2014 NFPA 58: Liquefied Petroleum Gas Code provides today's criteria for all aspects of the safe design, construction, installation and operation of the full range of LP-Gas piping, equipment, and venting, along with highway transportation of LP-Gas. New rules for cathodic protection for underground tanks guards against corrosion to preserve structural integrity.
In most areas of the country, soil characteristics are detrimental to the integrity of steel containers buried underground. Corrosion creates pits or holes that left alone or ignored can lead to leaks, releasing propane into the ground. The 2014 NFPA 58 requires ASME containers to have a cathodic protection system installed and periodically monitored to be sure it continues to meet expected performance standards. A new Supplement in the companion 2014 NFPA 58: LP-Gas Code Handbook further discusses this important topic.
Other 2014 Code changes that make installations more secure include:
- Prohibition against using former rail car tanks as they do not meet standards of the ASME Boiler and Pressure Vessel Code
- New and revised requirements to ensure adequate training of people who install or handle propane tanks and piping materials
- Revised definitions clarify terminology for better understanding, application, and enforcement of rules
Base your decisions on the latest hazard knowledge and mitigation strategies and achieve a higher level of propane safety. NFPA 58 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
