Abstract

PROBLEM TO BE SOLVED: To provide a fire extinguishing system and a fire extinguishing method in a coating booth, wherein a two-step fire extinguishing system method of an initial fire extinction when a fire is generated, and a normal inert gas fire extinction of carbon dioxide or the like is adopted, and therefore, workers can easily evacuate right after the generation of the fire and before an inert gas fire extinguishing system starts operating, and thus, safety can be ensured, and also, the recovery work for the fire extinguishing equipment after the initial fire extinction can be facilitated and speed up. SOLUTION: In the coating booth 1, a fire extinguishing system 12 is jointly provided in addition to the normal inert gas fire extinguishing equipment 13 of carbon dioxide or the like. In this case, the fire extinguishing system 12 emits a water mist comprising fine water particles, which is used for the initial fire extinction when a fire is generated. The water mist fire extinguishing system 12 uses a first fire sensor 14 and a water mist jetting head 15. In this case, the first fire sensor 14 senses a small fire right after the fire starts when the fire is generated. The water mist jetting head 15 emits the water mist comprising fine water particles while interlocking with the operation of the first fire sensor 14.

When a fire occurs in a paint booth, a carbon dioxide fire extinguishing system is activated in conjunction with the operation of a fire detector, and automatically closes an opening such as an entrance of the paint booth. Carbon dioxide is emitted. However, workers may be present in the paint booth at the time of fire, and in this case, if the paint booth is automatically closed before the fire extinguishing agent is radiated, it may be trapped in the paint booth and lead to a fatal accident. Included. In addition, since the carbon dioxide fire extinguishing system is activated even in the case of a trivial fire, rebuilding the fire extinguishing system after the fire extinguishment requires expensive refilling of the carbon dioxide storage container and requires a great deal of labor. However, there was a disadvantage that the painting booth could not be used until it was restored.
