Clean Agent Extinguishers

NFPA 2001 has defined the term “clean agent” as an electrically nonconductive, volatile or gaseous fire extinguishing agent that does not leave a residue upon evaporation. Since the banning of Halon in 1994, after it was found to deplete the ozone, the three most common clean agents used in fire suppression systems are: 3MTM NovecTM 1230 Fire Protection Fluid1, ChemoursTM FM-200TM Fire Suppressant2 and inert gases. Clean agent fire extinguishers are effective on Class B and Class C fires (used typically for petrol, oil, propane, butane, etc.) and work by releasing gas into the air, reducing the oxygen that feeds the flames without damaging equipment by leaving a residue.
