To rationally and effectively extinguish a fire in an instant by applying a suffocating action to rarefaction of oxygen by smoking radiation.

Combustion that takes place on the earth does not occur as long as the supply amount of oxygen required for combustion is insufficient even if a combustion material obtains temperature that reaches a fire point. In this constitution, the fire is extinguished in an instant by adopting a means for radiating smoking to a combustion part to rarefy the concentration of oxygen. To prove this principle with a simple object, for instance, if a small amount of newspaper or the like is burnt and a lighted candle is brought close to a place where smoke rises, a flame disappears in an instant. An apparatus designed and manufactured to utilize this natural phenomenon is used.
