木材作为一种常用物资,在大多数的火灾现场中均能找到其燃烧的痕迹。而对木材燃烧痕迹进行分析,根据其形成遗留过程和特征可直接或间接证明火灾发生时间、起火点位置、起火原因、扩大过程、蔓延中线、火灾危害结果、火灾事故责任等。因此对木材燃烧痕迹进行研究分析是火灾勘察工作的重要过程,是火灾原因认定的重要依据之一。一、木材燃烧痕迹的种类木材燃烧痕迹的形成,主要是受高温作用的缘故,但是其形成过程和呈现的特征会因作用的热源不同而有差异。
As a common material, wood can find traces of its burning at most fire sites. The analysis of the burning traces of wood can directly or indirectly prove the occurrence time of the fire, the location of the fire point, the cause of the fire, the expansion process, the midline of spread, the result of the fire hazard and the responsibility of the fire accident according to the process and characteristics of its formation. Therefore, it is an important process of fire investigation to study and analyze the burning marks of wood and it is one of the important bases for identifying the cause of fire. First, the types of wood burning marks The formation of wood burning traces, mainly due to the role of high temperature, but the formation process and the characteristics presented by the role of different heat sources vary.
