METHOD OF CHARGING OF SELF-ACTUATED FIRE-EXTINGUISHER Russian patent published in 1996 - IPC

FIELD: fire-fighting equipment. SUBSTANCE: method of charging of self-actuated fire-extinguisher made in the form of a cylindrical vessel consists in laminar charging of extinguishing powder and gas-forming agent to be placed in the middle part of the vessel between the layers of extinguishing powder; each layer is compacted separately; and gas producer with an initial decomposition point range within 95 to 200 C is used as gas-forming agent, its amount being within 4 to 8% of the vessel volume, than the vessel is sealed. Filling of the vessel to 93-99.5 of its volume before its sealing, as well as manufacture of the vessel from glass, 1.0 to 2.0 mm thick, are preferable. EFFECT: quick response of fire-extinguisher in case of inflammation and suppression of fireplace in the initial stage, which prevents further propagation of fire. Enhanced reliability and quick reliability of fire-extinguisher are well preserved after transportation. 4 cl, 2 tbl
