An aerosol-forming composition for fire suppression contains alkali metal nitrate as an oxidant, a novolac-type phenol formaldehyde resin and an epoxide resin as a fuel/binder, a mixture of sodium carbonate and at least one alkali metal salt and carbonic acid as an additional fuel that simultaneously fulfills the function of a coolant, a gas-forming buffer component and a steam-regulating component, a mixture of magnesium hexacyanoferrate (II) (Mg2[Fe(CN)6]) with cobalt (II) nitrate (Co(NO3)2) and with promoting additives of aluminum oxide and copper oxide as a combustion modifier. The proposed composition makes it possible to reduce the concentration of toxic substances in its combustion products, and also provides high thermodynamic stability and, as a result, heat resistance, impact resistance, moisture resistance and safety of use of the composition, including under severe climatic conditions.

Abrégé

The invention relates to firefighting technology, in particular to hybrid fire-extinguishing systems, and can be used for extinguishing fires in the engines of vehicles. The present fire-extinguishing device comprises: a cylindrical body provided with a lid, said lid having a pyrotechnic generator for a fire-extinguishing aerosol installed therein; an aerosol accumulation chamber; and a reservoir for a liquid fire-extinguishing agent. A plunger provided with a membrane is installed between the aerosol accumulation chamber and the reservoir for a liquid fire-extinguishing agent and expels the liquid fire-extinguishing agent through an outlet opening which is located in the bottom of the body. A valve is installed in the outlet opening and is provided with a rod which breaks the plunger membrane upon contact with the valve. The device makes it possible to prevent an aerosol stream from reaching a high temperature and to reduce the formation of particulate clumps which block the nozzle openings of spray nozzles in the fire-extinguishing system.
