一起避雷器爆炸引发火灾的调查

Fire investigation on a conductor explosion fire

对于比较少见的设备故障引发的火灾,在进行火灾事故调查时,必须要在调查的基础上认真细致地勘查火灾现场,在取得充分证据的前提下,确定起火部位、起火点,同时对一些不可能的因素进行排除,对可能引发火灾的因素逐一列举,对一些特殊的设备研究其工作原理、功能、特点、常见故障以及故障原因、后果,认真研究其中相互作用的因果关系,并且辅以必要的鉴定或实验进行验证,必要时对有关的设备进行拆解,以查找相关的直接证据。

As to some fire investigation induced by rare equip ment fault, firstly fire renaissance should be made seriously and fire point identified with full evidence, impossible factors must be excluded and possible factors analyzed. Secondly, to some special equipment,its operation principle, function, feature, nor- real fauh, cause and consequence should be analyzed and causation studied. Thirdly, to verify the results experiment sould be made, and when essentially some equipment could be taken apart to find direct evidence.
