First, dry powder fire extinguishers should be used for fires caused by gas and natural gas. As shown in the figure:

2. Facing the fire caused by gas and natural gas, the correct treatment is:

1. When the liquefied gas tank leaks and catches fire, don't panic. Without igniting nearby combustible materials, immediately close the valve of the gas cylinder, cool the cylinder with cold water, cover the cylinder with wet towels and wet bedding to suffocate the flame, and then move the cylinder to a safe place and immediately notify the gas company to deal with it.

2. In case of liquefied gas leakage due to the damage and failure of the angle valve, the leaking place should be wrapped with a wet towel first, and then the gas cylinder should be moved outdoors to drain the residual gas. Remember to put an end to all fire sources. ?

3. If a dry powder fire extinguisher is used, the correct fire extinguishing method must cut off the fire source from the gas bottle mouth and close the angle valve at the same time when the fire goes out. And remove the surrounding items that may cause burning to prevent major accidents.

4. When the room is full of smoke and the fire is strong, first open the doors and windows, and look for the cylinder while fighting the surrounding flames. Put out the cylinder fire according to the first method, cut off the gas source, and cool the cylinder with water and move it to a safe place. In addition, we should report to 119 in time. ?

5. When the cylinder burns standing, it will not explode generally, so it can be put out quickly. If the cylinder falls to the ground or the pressure reducing valve burns towards the ground, people should not approach it blindly, because the liquid in the lying cylinder will flow out through the bottle mouth and expand rapidly by 251-311 times, resulting in high temperature during combustion, which will lead to the explosion of the cylinder and personal injury. At this time, the cylinder can be cooled by using the cover to prevent explosion, and wait for the firefighters to come and deal with it.
