| Abstract: | In view of the characteristics of fire extinguishing of the underground rail transit and with reference to the practices in Chengdu Metro engineering,this paper details the operation and control of gas fire control system and addresses the implication of the system in the metro design. Conclusions show that IG541 mixed gas is better than others by comparison of Heptafluoropropane( FM 200) with IG541 mix gas in terms of environmental protection safety,economy,efficiency and the impacts on the protected.The index of the two gases in ODP,GWP,ALT and security index of LOAEL,NOAEL and LC50 are analyzed to support the conclusions. |
