Fire, T1, at 35.25 seconds, before application of condensed aerosol suppressant

 

 

 

Fire, T2, at 36.13 seconds, as condensed aerosol suppressant is just deployed

 

 

 

Fire, T3, at 36.20 seconds, as condensed aerosol suppressant has been deployed

 

 

Fire, T4, at 36.25 seconds, fully extinguished after application of condensed aerosol suppressant

The extinguishing performance of condensed aerosol fire suppressants is dependent on the density of aerosol particulates in the immediate vicinity of the flame. As with gaseous fire suppression systems, the faster the agent can build around the flame, the more efficient the extinguishing agent will be in terminating the flame’s combustion process. The extinguishing and design densities of aerosol fire suppression agents are generally expressed in kilograms per cubic meter (kg/m^3). Thus, the efficiency of aerosol extinguishing agents varies depending on a number of factors, such as the location of the aerosol relative to the flame, the proximity of other combustible flammable materials, the type of fuel involved, etc.

 

Condensed aerosol devices are designed to provide a controlled discharge. The aerosol-forming compound is installed inside of the device, which is then fitted with an electric or mechanical initiator. The electric initiator is interfaced with a fire detection control unit or panel, which can be remotely operated by physical means such as by cable, hand operated with a fuse mechanism such as those used in smoke dispensing grenades, or automatic and self-triggering when outfitted with an integral heat-sensing device.
