Document Type and Number:
WIPO Patent Application WO/2021/149758
Kind Code:
A1
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.
