Extraction Method of Electrical Fire Material Evidence

Abstract

Fire cause investigation is a multidisciplinary comprehensive technology, involving electrical science, mechanics, materials science, chemistry and other professional disciplines. The identification of fire material evidence plays a very important role in fire investigation, so the extraction method of material evidence will have a direct impact on the identification results. On the macro level, physical evidence and chemical evidence that are required to be extracted from the fire site can be divided into physical evidence and chemical evidence, so as to extract the most valuable fire material evidence and provide strong evidence for the investigation of fire causes. This is a skill that fire investigators must master. The accuracy of material evidence extraction will greatly improve the efficiency of fire investigation and ensure the accuracy of cause investigation.
