Heptafluoropropane（HFC227ea/FM200）is known for its for you as a new fire extinguishing agent, KaiYuan fire extinguisher series products have Heptafluoropropane fire extinguisher in the product, the following is to make a brief introduction of its features.　　 Heptafluoropropane gas at room temperature is a colorless, odorless, nonconductive, non-corrosive, without environmental restrictions, atmospheric remaining period is shorter. Extinguishing fire mechanism is mainly the interrupt combustion chain, extremely fast, the eco-systems is good precision electronic equipment and valuables. Heptafluoropropane non-toxic reaction (NOAEL) concentration was 9%, the toxic reaction (LOAEL) concentration was 10.5%, the general design Heptafluoropropane concentration less than 10%, safe to human body. (containing fluorine halon extinguishing agent under the high temperature of fire scene, will produce hydrogen fluoride (HF) gas, for precision instrument and equipment produce mild acid erosion; but does not cause a harm to human body.) Its characteristic has a good clean (in the atmosphere completely vaporized without residue), gas phase of good electricity insulativity, and good applicable to use the physical properties of fire extinguishing system. Heptafluoropropane is an ideal halon substitutes, no damage to the ozone layer of the atmosphere, consumption of atmospheric ozone layer ozeme depletion potential ODP zero, but there is a lot of the greenhouse effect, the GWP < 0.5. FM200 has good fire extinguishing effect, and by the U.S. environmental protection agency recommended by American NFPA2001 and ISO approved.
