What does NFPA 52 regulate?

NFPA 52 specifically addresses the installation and operation of gaseous hydrogen and compressed natural gas (CNG) vehicular fuel systems. This standard outlines the safety requirements and best practices necessary to ensure that vehicles powered by these alternative fuels are installed in a manner that mitigates risks associated with fuel leakage, explosion, and other hazards. It is essential for ensuring the safe integration of hydrogen and CNG into the transportation sector, including aspects such as fueling stations, vehicle design, and maintenance protocols.

Other choices relate to different aspects of fuel safety and regulation but do not accurately reflect the scope of NFPA 52. For example, while the sale of LPG and the maintenance of fuel storage tanks are significant, those topics fall under other regulations or standards. The transportation of hazardous materials is also governed by separate regulations that focus primarily on the logistics and legalities involved rather than the specific concerns covered by NFPA 52.
