Common fire extinguishing methods for families

Once you start a fire at home, you should not panic first, and then take scientific methods to extinguish it. Several common fire extinguishing methods are introduced:

1. The flushing cooling method sprays water directly onto the combustibles to extinguish the flame, or sprays water onto the unburned combustibles nearby to protect the combustibles from the threat of flame thermal radiation and avoid combustion.

2. The method of isolating air covers the surface of combustibles with non combustible materials such as wet cotton quilts to isolate air and extinguish the fire.

3. Combustibles and combustibles near the fire shall be removed from the burning area by the spread prevention method; Separate combustibles and combustion aids from the combustion area; Prevent burning objects from flying away to prevent combustion spreading.

If a fire at the initial stage occurs at home, it can also be extinguished by covering it with a soaked quilt or gunny bag. Why is this?

The oil pan caught fire while we were cooking at home. Just cover the oil pan with a lid quickly, and then open the pan. This is because the lid separates the oil on fire from the air. If the oil cannot get enough air, it will not get the necessary oxygen. Without oxygen, the oil cannot continue to burn. In the same way, wet quilts, gunny bags, etc. are used to cover the combustibles on fire, and all combustibles are covered to prevent oxygen from entering and extinguish the fire. However, the key to dealing with the incipient fire is to be "fast", so that the fire cannot have the opportunity to expand its spread.
