DETECTION OF TRACES OF COMBUSTION INITIATORS AFTER A FIRE ON PVC PRODUCTS BY PORTABLE GAS ANALYZER, BY PRODUCTION OF FIRE-TECHNICAL EXAMINATION
In practice, a specialist (investigator) during the fire technical examination, in order to establish the cause of a fire, has to evaluate (select) fragments of building materials from fire zones with various thermal injuries. Often the objects for research are materials based on polyvinyl chloride (PVC). To do this, using portable devices, a preliminary analysis of surfaces exposed to heat is carried out. One of such devices is the «Kolion-1V» gas analyzer, which allows to determine the participation of hydrocarbon initiators of combustion during the burning of solid combustible materials.
