Identification method of indoor fire site or fire point

Abstract

The invention discloses anidentification method of an indoor fire site or fire point. The method comprises the following steps: firstly initially identifying a suspected fire site or fire point; by taking the initially identified suspected fire site or fire point as a center, selecting points and collecting checked materialsat an equal interval according to the outward symmetrical diverging direction, and confirming samples; performing the comparative analysis of components of ashes at the suspected fire sites and the collected samples in the diverging direction through an electron microscopy-energy spectrum analyzer, thereby confirming the fire spreading direction; and finally, selecting more than or equal to three fire spreading directions, if an intersection of extension lines of directions opposite to the fire spreading directions is overlapped with the initially identified suspected fire site or fire point, identifying that the initially identified suspected fire site or fire point is the fire site or fire point.

Description

technical field [0001] The invention relates to a method for identifying a fire point, in particular to a method for identifying a fire site or a fire point of an indoor fire. Background technique [0002] The identification of the location or point of fire is the basis of identifying the cause of a fire. It plays a very important role in the determination of fire responsibility and responsible person, fire prevention and social public safety. The Ministry of Public Security has revised the "Fire Cause Identification Rules" several times. In the "Interim Rules for Fire Cause Identification" (Gong Xiao [2011] No. 43) promulgated in 2011, a direct identification method was adopted for "electrical fires", while for "other fires "The "exclusion method" is adopted. The method of directly identifying the cause of the fire can generally identify the fire point and identify the cause of the fire. The "exclusion method" follows the fire site investigation procedures of "environment...

Problems solved by technology

However, the "most violent and most serious burning part" is closely related to the flammability and quantity of the burning substance, and is not necessarily the earliest burning part. Therefore, the fire site or fire point cannot be identified based on the violent and serious degree of burning

The method of determining the location or point of fire based on empirical deduction or comprehensive analysis has insufficient scientific basis and many doubts, which brings disadvantages to the determination of the cause of the fire and the handling of the person responsible.

At present, there is no method to identify the fire location or fire point based on the carbon content of the burning ash.
