NFPA-37(15): Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines
Update to the 2015 edition of NFPA 37: Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines for the latest on safe engine operation.

Minimize fire hazards by staying up-to-code. The 2015 edition of NFPA 37 governs the installation and use of stationary engines and gas turbines fueled by liquid or gaseous fuels as prime movers for emergency generators, fire pumps, and stand-by and peak power systems. Requirements address system installation, fuel supplies, lubricating systems, engine exhaust systems, control and instrumentation, instructions, and fire protection features.

Designers, installers, and AHJs will work more efficiently and confidently with the latest provisions, including key changes:

  • General installation requirements for engines and turbines are revised to require compliance with wind and seismic design criteria.
  • Subsection 5.2.1 is amended to specify the type of regulator required and other changes that enhance the safety of the fuel supply system.
  • Revision in Subsection 5.2.2 allows the use of a proof-of-closure switch or a valve proving system as alternatives to a vent valve between the two automatic safety shutoff valves -- providing greater flexibility for system designers.
  • New Subsection 9.3.3 reinstates the vital requirement for a purge cycle in the start cycle for combustion gas turbines.
  • Paragraphs 11.4.4.1.1 and 11.4.4.2 are revised to clarify the performance criteria for total flooding gaseous agent suppression systems and local application gaseous agent suppression systems with respect to cool-down of the engine or turbine.
  • Annexes to both paragraphs above are revised to incorporate additional clarification and a new Subsection 11.4.8 has been added to address retrofit of existing fire suppression systems. These amendments help the user ensure that suppression systems will perform as intended.

Loss prevention professionals; designers and installers of stationary engines for fire pumps, standby power supplies, and emergency generators; insurers; and AHJs need the 2015 edition of NFPA 37 to help improve safe engine operation and minimize fire hazards. (Softbound, Approx. 26 pp., 2015)
