DISASTER FOR FIRE PREVENTION FIREFIGHTING SYSTEM AND ITS METHOD

Disaster prevention fire extinguishing system and extinguishing method are provided, which extinguish fire by stopping circulation of the air by using a protection cover. A disaster prevention fire extinguishing method comprises: a step(S300) for sensing heat in case the fire occurs using an arbitrary sensor adhered to the support stand positioned at the neighboring of object or object including the cultural assets and building; a step(S310) for cutting off the circulation of the internal air and external air around the protection cover; a step(S320) for sensing the inner heat when the heat sensed through the sensor of the inside gradually increases; and a step(S330) for spraying the fire-extinguishing agent from a nozzle of the support stand.
