Heptafluoropropane is a chemically clean gas-based fire extinguishing agent, a colorless, odorless, low toxicity, non-conductive, non-pollution. Heptafluoropropane ozone depletion potential ODP = 0, global warming potential GWP = 0.6, the atmosphere remaining lifetime ALT = 31 years, fire-extinguishing agent toxicity - "No adverse reactions were observed concentration" NOAEL = 9%, extinguishing the basic design concentration C = 8%, to chemical-based fire-fighting mode. As Halon ideal substitute Heptafluoropropane according to toxicity index as a total flooding fire extinguishing system is applicable to occupied areas, that can be used to protect people often work or a place to stay. At present, the international community fire extinguishing system as an alternative to Halon systems are becoming more and more show experience from application fire extinguishing system can effectively achieve the desired protection purposes.
