Cooling method
The principle of this fire extinguishing method is to spray the fire extinguishing agent directly on the burning object to reduce the temperature of combustion below the ignition point and stop the combustion. Or spray the fire extinguishing agent on the material near the fire source, so that it will not form a new fire point due to the heat radiation of the flame. The cooling fire extinguishing method is one of the main methods of fire extinguishing, and water and carbon dioxide are commonly used as fire extinguishing agents to cool down and extinguish the fire. The fire extinguishing agent does not participate in the chemical reaction in the combustion process during the fire extinguishing process. This method is a physical fire extinguishing method.
Isolation method
The isolation fire extinguishing method is to isolate or remove the burning material from the surrounding unburned combustible material, interrupt the supply of combustible material, and stop the combustion due to lack of combustible material. The specific methods are:
1. Remove combustible, combustible, explosive and combustion-supporting materials near the fire source;
2. Close the valves of combustible gas and liquid pipelines to reduce and prevent combustible substances from entering the combustion zone;
3. Try to block the scattered flammable and combustible liquids;
4. Demolition of flammable buildings adjacent to the fire source to form a space zone to prevent the spread of fire.
Asphyxiation
The suffocation fire extinguishing method is a fire extinguishing method that prevents the air from flowing into the combustion zone or uses the incombustible zone or dilutes the air with incombustible substances, so that the burning substance does not get enough oxygen and extinguishes. The specific method is:
1. Cover the burning material with incombustible or non-combustible substances such as sand, cement, wet sack, wet quilt;
2. Spraying water spray, dry powder, foam and other fire extinguishing agents to cover the burning material;
3. Fill containers and equipment in fire with water vapor, nitrogen, carbon dioxide and other inert gases;
4. Airtight fire buildings, equipment and holes;
5. Spray non-combustible gas or non-combustible liquid (such as carbon dioxide, nitrogen, carbon tetrachloride, etc.) into the combustion area or on the combustion material
