地铁火灾分析及应对措施

Subway fire analysis and countermeasures

从国内外地铁火灾案例统计和安全理论分析方面归纳地铁火灾的主要成因和形式,提出电气火灾为地铁火灾的主要成因之一,强化地铁火灾报警系统的设计可以从源头上避免电气火灾的发生。调研分析当前地铁火灾报警系统设计存在的问题,包括火灾探测报警的设计理念滞后、火灾报警系统的选型难度大等,进一步提出相应的建议,包括不同部位火灾探测器的选择、应急疏散广播系统和手动火灾报警按钮的设置等。

Based on statistics of subway fire cases in and abroad and analysis of security theory, the main reason and types of subway fire were summarized, it was concluded that the main cause was electrical fire, and strengthening subway fire alarm system design could avoid electrical fire from the source. The problems in subway fire alarm system design were analyzed including lagging design concept and difficult system selection, and further put forward the corresponding suggestions including selection of fire detector in different parts and setting of evacuation broadcast system and manual fire alarm button.
