NFPA 17A: Standard for Wet Chemical Extinguishing Systems 2017
Fire suppression systems and equipment are vital for minimizing damage and saving lives during emergencies. NFPA 17A, Standard for Wet Chemical Extinguishing Systems, establishes the requirements for the design, installation, operation, testing, and maintenance of these systems throughout their service life. This standard is focused on ensuring the integrity and reliability of systems that discharge wet chemical agents through fixed nozzles and piping using expellant gas. Its provisions apply to systems commonly found in restaurants and institutional kitchens, including hoods, plenums, ducts, and cooking appliances. NFPA 17A covers every aspect—from system components and design plans to acceptance testing, inspection, maintenance, and recharging—to help ensure effective fire protection where it’s needed most.
