Investigation and analysis of a fire in a wine workshop transformed from a civil building

分析一起“民改生”制酒作坊火灾的调查过程。重点介绍火灾调查人员如何在证人之间存在利害关系、证人证言相互矛盾、现场痕迹分析难度大、关键痕迹物证缺乏的情况下,通过视频分析查找突破口,测量光线夹角确定起火部位,进行模拟试验反推起火原因,调查同类设备完善证据链条,最终准确认定起火原因。并对火灾诱因、灾害成因、火势蔓延扩大原因进行了深入分析,为此类火灾的调查提供了清晰的思路,对此类火灾的调查提出了工作建议。

This paper analyzed the investigation process of a fire in a liquor workshop which belongs to the situation of the civil buildings transformed into productive buildings. The report emphatically illustrated how investigators had determined the cause under circumstances of the interest between witnesses, the inconsistency in testimony, the difficulty of field-trace analysis, and the absence of critical trace evidence. The videosurvey technique was implemented to make a breakthrough.The angle of light was measured to determine the ignition spot.Simulation tests were conducted to invert the origin of the fire,and similar equipment was investigated to improve the evidence chain. Eventually, the cause of the fire was accurately determined. The investigation process makes an in-depth analysis of the inducing factors, forming origin and spreading reasons for this kind of fire, and provides clear ideas and suggestions for a similar case.
