能谱分析技术在一起火灾物证溯源中的应用

Application of energy spectrum analysis technique in evidence source tracing of a fire

在一起疑难住宅火灾调查过程中,遇到原因认定难题,无法认定是电动轮椅线路故障引发火灾,还是住宅内其他用电电器的电气故障引发火灾。通过对仅有的一段线路熔痕及黏附物采用能谱分析等先进技术,追溯本源线索,科学认定了起火原因,研究可为类似火灾调查工作提供参考。

A cause indentification problem occurred during the fire cause investigation of a residential fire.It was a difficult issue to ascertain the ignition source between electrical fault of the electric wheelchair and that of other electric appliances.The energy dispersive spectrum analysis was employed to confirm the fire source.On this basis,the fire cause was determined.The study can provide reference for similar fire investigation.
