Abstract: Provided is an aerosol fire extinguishing agent composition which can be used as a fire extinguishing agent when a fire occurs. The aerosol fire extinguishing agent composition is characterized in that the amount of a fire extinguishing agent (fire extinguishing concentration of aerosol) required for fire extinguishing specified in a cup burner test is 1200-1800 g/m3.

Abstract: Disclosed is a method for producing a fire-extinguishing member, including steps of: preparing an adherend that has a surface to be treated; and forming a fire-extinguishing-agent-containing layer on the surface to be treated by a wet coating method to obtain a fire-extinguishing member that includes the adherend and the fire-extinguishing-agent-containing layer provided on the surface to be treated, wherein the fire-extinguishing-agent-containing layer contains a binder resin and a fire-extinguishing agent component that is combusted to generate an aerosol.

Abstract: The present invention discloses a fire extinguishing sheet which is used in places, facilities, devices, tools, structures and the like where a fire may break out, and which makes initial fire extinguishing possible. This fire extinguishing sheet contains at least a potassium compound as a fire extinguishing chemical that is thermally decomposed upon reaching a predetermined temperature and generates a fire extinguishing component; and this fire extinguishing sheet is arranged in places, facilities, devices, tools, structures and the like where a fire may break out. If a fire breaks out, aerosols containing potassium radicals (a potassium compound) are generated from the fire extinguishing sheet, and the chain of combustion is interrupted by a negative catalytic effect, thereby quickly extinguishing or suppressing the fire.

Abstract: The present invention provides a fire extinguishing sheet suitable for productivity, mass production, and large-scale production, wherein the fire extinguishing sheet can be used in places, facilities, structures, etc., where a fire may occur, and has an initial fire extinguishing function. The fire extinguishing sheet according to the present invention contains a fire extinguishing agent that when a predetermined temperature is reached, thermally decomposes to generate a fire extinguishing component.
