Abstract

We studied the extinction effectiveness of pyrogenic condensed-aerosols in gaseous fire extinguishing systems through the ISO (International Organization for Standard) 15779. The thermal characteristics of solid aerosols as an extinguishing agents were evaluated by using TG and DTA. The modified closed pressure vessel test (MCPVT) and the conductivity of the solid aerosol extinguishant were also measured to ensure the safety of extinguishant. The TG and DTA result showed that the resin added to the main component of Potassium Nitrate (PN) has the effectiveness to mitigating the exothermic reaction of the pyrogenic condensed-aerosol extinguishant. The results of maximum height test revealed the extinguishing capability of a pyrogenic condensed-aerosol extinguishing agent as a gaseous extinguishing system.
