火场助燃剂类物证封装容器保存性能研究进展

Research progress on preservation performance of packaging containers for combustion supporting agents in fire scene

从火场提取的助燃剂类物证在保存过程中,可能因多种因素造成污染,从而影响其证据效力,进而影响司法公正。对国内外相关研究进行了梳理,介绍了保存过程中封装容器对助燃剂类物证的背景干扰,以及可能存在的交叉污染和物证损失,并且对封装容器的选择进行了总结归纳。研究可为助燃剂物证的科学有效保存提供参考。

During the preservation of the combustion supporting agent material evidence extracted from the fire site,it may be polluted by many factors,which will affect its evidence effectiveness and the judicial justice.This paper combs the relevant research both in China and other countries,introduces the background interference of packaging containers on combustion supporting agent physical evidence,as well as the possible cross pollution and loss of physical evidence,and summarizes the selection of packaging containers.The study can provide reference for the scientific and effective preservation of combustion supporting material evidence.
