Composition Measurement Period of Samples Under Flammable Materials Fire

In the event of a fire, flammable materials may become a cargo of initial ignition. when the fire investigators arrive at the site after a fire occurs, the components may not be found in the debris of the site due to rapid evaporation. It is essential to collect samples from the debris of the site. It should be measured and analyzed for the flammable components to investigate the cause of the fire. Depending on the fire extinguishing method, the period of measurement of the flammable components in the samples of the debris of the fire site was slightly different, and the detection period became longer as the natural extinguishing, extinguishing by fire extinguisher, extinguishing by water from fire hoses, and suffocation extinguishing progressed. In the case of suffocation extinguishing covered with a cover sheets, the component detection was possible up to 12 days. The detection technique was proposed to strengthen the fire investigators' ability to detect inflammatory substances.
