TY - JOUR PY - 1999// TI - Burning characteristics of selected substances: Influence of suppression with water JO - Fire and materials A1 - Hietaniemi, J A1 - Kallonen, R A1 - Mikkola, E SP - 149 EP - 169 VL - 23 IS - 4 N2 - The influence of suppression with water spray on the burning characteristics and composition of fire effluents of nylon, polypropylene and two industrial chemicals was investigated The experiments were performed using a controlled-atmosphere cone calorimeter in which the ventilation conditions could be altered. The water spray was applied with a single horizontally positioned nozzle. In the experiments time to ignition, rate of heat release, sample weight and smoke production as well: as the composition of the fire effluents were measured; the chemical analysis techniques employed were Fourier-transform infrared spectroscopy and gas chromatography/mass spectroscopy. The results give quantified information on the effects that water application may have on the burning and the properties of the exhaust gases. A comparison with results of similar experiments with no water application reveal notable changes, e.g. in the production of the toxic fire effluents.
