对一起激光雕刻机火灾的调查及思考

Investigation and reflection on a laser engraving machine fire

通过对一起激光雕刻机火灾事故的调查,利用环境勘验、初步勘验、细项勘验及专项勘验分析了火灾发生的过程,确定起火时间、起火点及起火部位。利用排除法,结合模拟实验及技术鉴定,认定起火原因为激光雕刻机运行产生的火花引燃雕刻生成的碎屑导致火灾。结果可以为同类火灾事故调查提供参考。

By investigating on a laser engraving machine fire,through environmental investigation,preliminary investigation,detailed inspection and special investigation,the fire process was analyzed,and the fire time,fire point and fire location was identified.Using exclusive method,combined with experiment test and technical identification,the fire cause was identified as sparks generated by the working laser engraving machine igniting debris generated by engraving.The results can give references for similar fire investigation.
