| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a foam fire extinguishing system which can extinguish flames in a short period of time even when the flames are raging furiously, by intensively discharging a fire-extinguisher to an origin of fire, and which can also be effectively used particularly in a clean room of a semiconductor factory.SOLUTION: A fire-extinguishing foam head is set to radially discharge a fire-extinguisher to a narrower range than a conventional fire-extinguishing foam head. A deflector and an air intake port are not provided. An alcohol-resistant foam fire-extinguisher higher in pressure and density than a fire-extinguisher supplied to the conventional fire-extinguishing foam head is supplied. The fire-extinguisher is intensively and directly discharged by identifying an origin of fire, in which the fire breaks out.
【課題】火災源に対して集中的に消火剤を放出して火勢が強くても短時間でこれを消火することができ、特に半導体工場のクリーンルームにおいても有効に用いることのできる泡消火装置の提供。【解決手段】消火用泡ヘッドを従来の消火用泡ヘッドよりも狭い範囲に放射状に放出するようにし、デフレクタや空気取込口を設けず、従来の消火用泡ヘッドに供給されるより圧力と濃度の高い耐アルコール性泡消火剤を供給し、火災の発生した火災源を特定して集中的かつ直接的に消火剤を放出する。【選択図】図３ |
