Apply the 2018 edition of NFPA 51 to reduce the risk of fire and explosions with requirements governing oxygen-fuel gas systems.

NFPA 51: Standard for the Design and Installation of Oxygen-Fuel Gas Systems for Welding, Cutting, and Allied Processes provides the latest fire safety requirements for gas-fueled systems. This document works hand-in-hand with NFPA 1: Fire Code, NFPA 400: Hazardous Materials Code, NFPA 5000®: Building Construction and Safety Code®, and other NFPA® National Fire Codes.

Industry professionals, design engineers, and code enforcement officials need NFPA 51 for the latest guidance on cylinder storage, system manifolding and piping, and associated protective equipment such as regulators. The Standard also includes provisions for the use of acetylene generators, calcium carbide storage for acetylene generators, and mobile acetylene trailer systems.

Changes in the 2018 edition of NFPA 51 improve consistency with the latest edition of NFPA 55.

Updates to information extracted from and references to the 2016 edition of NFPA 55: Compressed Gases and Cryogenic Fluids Code help fill the safety gap with the most comprehensive set of industrial gas requirements in the industry.
