FIELD: fire safety.
SUBSTANCE: invention relates to fire extinguishing techniques, namely portable fire extinguishers and fire extinguishers for fire and explosion prevention and fire fighting with inorganic fast-hardening foam. Chemical foam fire extinguisher contains a sealed enclosure with components A and B of the extinguishing agent placed in it, device for mixing the components A and B of the extinguishing agent and device for supplying the components of the extinguishing agent from the housing to the device for mixing the components A and B of the extinguishing agent with the pressure of the compressed gas inside the housing. Device for mixing components A and B of the fire extinguishing agent is made in the form of an ejector mixer-foam generator with the possibility of mixing components A and B of the extinguishing agent and foaming the mixture of components A and B of the fire-extinguishing agent into the air by ejector mixer-foam generator. Device for supplying components A and B of the extinguishing agent from the housing to the ejector mixer-foam generator are made in the form of a pipeline of component A and a component B pipeline located inside it.
EFFECT: improved reliability of the fire extinguisher and the effectiveness of fire extinguishing and fire and explosion prevention.
