Description

FIRE BLANKET

The present invention relates to a suffocating fire extinguisher for extinguishing a fire.

If a fire breaks out in a vehicle, the fire is extinguished using a fire extinguisher stored in the vehicle to quickly extinguish the fire.

However, if the flame is not large, it is possible to extinguish the fire using a vehicle fire extinguisher. However, due to the nature of vehicle fire extinguishers, which are mostly filled with a small amount of fire extinguishing agent, in the case of vehicles where flames spread easily, complete extinguishment is difficult.

Accordingly, when a fire occurs in a vehicle, quick reporting to the fire department and rapid fire extinguishment through sprinkler work using a fire truck are required.

However, the spraying method using a fire truck also had the problem that it took a considerable amount of time to completely extinguish the interior of the vehicle due to the nature of spraying from the outside, and there was a risk that the flame could easily spread to the surrounding area due to the exposed nature of the flaming vehicle. .

To solve this problem, the development of an asphyxiation fire extinguisher that extinguishes the fire by blocking the supply of oxygen by covering the vehicle on fire using cloth made of non-combustible materials, rather than using a fire extinguisher or water spray method, is required.

In particular, there is a need for the development of an asphyxiation fire extinguisher that blocks the supply of oxygen and sprays fire extinguishing water to enable rapid fire suppression.
