NFPA 52 Handbook-2013 PDF Download

The NFPA 52 Handbook-2013 standard is a publication that provides information and opinion but does not offer engineering or professional services. It is specifically focused on the design, installation, operation, and maintenance of compressed natural gas (CNG) and liquefied natural gas (LNG) engine fuel systems and dispensing systems for vehicles.

The purpose of this handbook is to provide up-to-date safeguards against hazards related to CNG and LNG fuels. The use of natural gas as a fuel has increased due to its cost advantage over petroleum-based liquid fuels, leading to a greater need for guidelines and safety regulations in this area. The handbook addresses fire safety rules for CNG and LNG fuel systems on all types of vehicles, as well as the compression, storage, and dispensing systems associated with these fuels.

A significant change in this edition is that the scope has been revised to exclusively focus on CNG and LNG vehicular fuels. Requirements for hydrogen vehicular fuels have been moved to another standard called NFPA 2: Hydrogen Technologies Code. This indicates that the handbook has been updated to provide more specific and targeted guidance for the safe use and handling of CNG and LNG fuels in vehicles.
