The NFPA 51-2023 standard aims to reduce the risk of fire and explosions associated with oxygen-fuel gas systems. It provides the latest fire safety requirements for gas-fueled systems and works in conjunction with other NFPA codes such as NFPA 1, NFPA 400, and NFPA 5000.

This standard is essential for industry professionals, design engineers, and code enforcement officials as it offers guidance on various aspects of oxygen-fuel gas systems. It covers topics such as cylinder storage, system manifolding and piping, and protective equipment like regulators. In addition, it addresses the use of acetylene generators, calcium carbide storage, and mobile acetylene trailer systems.

The 2023 edition of NFPA 51 incorporates changes to enhance consistency with other NFPA codes. It aligns the definitions of noncombustible material and limited-combustible material with other documents and includes updates from NFPA 55, NFPA 58, and NFPA 400.
