Help ensure safer and efficient use of CNG and LNG fuel systems and mitigate fire and explosion hazards.
With the steady rise in the use of cost-effective natural gas vehicles, it's critical to have access to the complete range of requirements for designing, installing, operating, and maintaining compressed natural gas (CNG) and liquefied natural gas (LNG) engine fuel systems and dispensing systems. NFPA 52, Vehicular Natural Gas Fuel Systems Code, offers in-depth instruction for helping to safeguard people and installations in a user-friendly format that’s easy to navigate and comprehend.
An essential for designers, engineers, maintenance professionals, facilities managers, contractors, and authorities having jurisdiction, NFPA 52 covers CNG and LNG systems on all types of vehicles and applies to facilities with LNG storage in containers of 100,000 gallons or less.
Additional subject areas include:
- Fuel compression, processing, storage, and dispensing systems
- CNG residential fueling facilities (RFF-CNGs)
- CNG nonresidential fueling facilities
- LNG fueling facilities
- LNG fire protection
- Installation of ASME tanks for LNG
- LNG and CNG on commercial marine vessels and pleasure craft
The 2026 edition features routine updates to existing references and extracts, plus a complete review and reorganization of mandatory requirements and fuel system types.
