摘　　要：针对某起汽修厂火灾事故进行调查分析,通过现场勘验、视频监控分析等方法认定该起事故的原因是电缆线过负荷引燃周边可燃物。同时考虑到喷漆房内潜在点火源有引燃在喷漆作业过程中产生的可燃漆雾的可能性,对喷漆厂房常用的若干种材料包括稀释剂、清漆、金属面漆、普通面漆、底漆和固化剂,测试火灾危险性参数,包括闪点、燃点和液体蒸气的爆炸下限。基于火灾调查结果和试验分析,总结汽修厂及其喷漆房火灾规律。研究可为此类事故的预防、救援、调查提供参考依据。The investigation of a fire accident in an auto repair factory are carried out.By fire scene investigation,video surveillance analysis,the fire cause was decided to be the cable overload igniting the surrounding combustibles.At the same time,considering the fire risk of potential ignition sources in the spray painting room may ignite the flammable paint mist generated during painting operation,fire hazard parameters test,including the test of flash point,combustion point and lower explosion limit of liquid vapor were performed on some materials commonly used,such as thinner,varnish,metal topcoat,common topcoat,primer and curing agent.the general rules of fire in the auto repair factory and the spray painting room are summarized based on the investigation and tests.The study can provide a reference for the prevention,rescue and investigation of such accidents.
