There are still halothane fire extinguishers, but halothane fire extinguishers in the 1211 fire extinguishers and 1301 fire extinguishers have been included in the national elimination of fire extinguishers catalog.
According to the study of alternative halothane 1301 extinguishing agent and the relevant norms and regulations in China, the current available gaseous extinguishing agents are: halothane 1301 (with restrictions on the use of), carbon dioxide, IG541 inert gases and halogenated hydrocarbons (sevofluoropropane) gas, etc.; these gases are used in the fire extinguishing system.
Seventy-fluoropropane fire extinguishers are selected because sevofluoropropane is colorless, tasteless, clean, low-toxicity, good electrical insulation, high fire-extinguishing efficiency, especially on the ozone layer is not destructive to the atmospheric residual time is relatively short, and its environmental performance is significantly better than halothane, so far, research and development is more successful in the development of a clean gas fire extinguishing agent that is considered to be a replacement for halothane 1301, 1211 It is considered to be one of the most ideal products to replace halothane 1301 and 1211.

Precautions for Heptafluoropropane gas fire extinguishing system:
Heptafluoropropane gas fire extinguishing system is generally common in the pipe network, cabinet, hanging type, these three also belong to the internal storage pressure of Heptafluoropropane gas fire extinguishing system, the delivery distance of 30 meters;
There is also an external storage pressure Heptafluoropropane gas fire extinguishing system, the delivery distance can reach up to 150 meters. system, its delivery distance can reach 150 meters, choose the gas fire extinguishing program, do not blindly choose, generally according to the size of the protective zone and the structure of the gas fire extinguishing program to choose the right, so as not to cause economic waste.
Common protective areas are:
Electronic computer rooms, data processing centers, telecommunication communication facilities, process control centers, expensive medical facilities, valuable industrial equipment, archives, libraries, museums and art galleries, clean rooms, anechoic chamber, emergency power facilities, flammable liquid storage areas, etc., but also can be used for production operations in fire hazardous places, like paint spraying production line,
Electrical aging of gas extinguishing solutions. p>
Electrical aging room, rolling mill, printing machine, oil switch, oil-immersed transformer, impregnation tanks, melting tanks, large generators, drying equipment, cement production process of coal silo, as well as ship cabin, cargo hold, etc., often people work and need to set up a gas protection of the region or place.
