Stored energy gas fire extinguishing

Can gas fire extinguishing agents reduce the temperature of battery?

Gas fire-extinguishing agents such as Halons, HFC-227ea, CO 2 and Novec 1230 are beneficial to integrity protection of battery system during the fire extinguishing process. However, gas fire-extinguishing agents could not effectively reduce the temperature of battery.

Do gaseous extinguishing agents improve fire suppression efficiency?

Before introducing new gaseous fire-extinguishing agents, the synergistic use of different extinguishing agents has a positive significance in improving fire suppression efficiency, reducing the use of extinguishing agents, reducing fire losses, and ensuring personal safety.

Are gas based fire extinguishing agents good?

Gas extinguishing agents present excellent fire-extinguishing performance, but the cooling effect is insufficient, which leads to the serious problem of re-ignition. While water-based fire-extinguishing agents demonstrate excellent cooling capability, but the extinguishing efficiency is insufficient.

Which fire extinguishing agent is best in enclosed space?

Gaseous fire-extinguishing agents show more excellent extinguishing capacity in enclosed space . Among gaseous fire-extinguishing agents, the extinguishing capacity of C 6 F 12 O and liquid nitrogen show best, followed by HFC-227ea .

Why are inert gaseous fire extinguishing agents non toxic?

Inert gaseous fire-extinguishing agents and N 2 and CO 2 are based on physical extinguishing mechanisms. This characteristic also contributes to the non-toxicity of humans within the normal design concentration range and does not produce toxic substances after extinguishing a fire.

Which fire extinguishing agent has a poor cooling capacity?

In addition, gaseous fire-extinguishing agents, dry powder and aerosol possess poor cooling capacity. Among other fire-extinguishing agents, the cooling ability of aerosol is worst, followed by dry powders, HFC-227ea, CO 2 and Novec 1230. The wettability is the index of the fire-extinguishing agent to moisten the surface of battery pack.
