Application Assessment of Electrical Cables during Smoldering and Flaming Combustion

Electrical cables are a potential source of ignition and fire hazards in various types buildings industrial installations, as well all modes transportation, including aircraft. Fires pose the greatest threat to human life health. The composition thermal degradation products depends mainly on type combustible materials combustion process—flaming or smoldering. purpose this paper was determine, based experimental studies, effects flaming smoldering response times smoke detectors. In addition, concentrations gases formed process duct combustion, CO, SO2, NO2, NO, HCN, HCl, HBr HF, were measured using an FTIR spectrometer. results presented confirm significant effect way cable samples burned detector tripping time. highest concentration (Y) test chamber obtained during flame combustion. It further found that characteristics insulation material used, such PVC, had toxicity emitted gases. largest amounts toxic with plasticized PVC sheath.
