What are the ways to put out the fire?

The fire extinguishing agent is directly sprayed on the combustible materials, so that the temperature of the combustible materials is reduced below the self-ignition point, thus stopping the combustion; A preventive method of cooling unburned combustible substances with water to prevent them from reaching the ignition point and catching fire.

The main function of extinguishing fire with water is to cool down and extinguish fire. Generally speaking, water can be used to cool down and put out fires.

2, suffocation fire extinguishing method

Combustible substances can't burn without air or the oxygen content in the air is lower than 14%. The so-called suffocation method is to cut off the air supply of combustion products.

Appropriate measures should be taken to prevent air from entering the combustion zone, or to dilute the oxygen content in the air with inert gas, so that the burning substance will be extinguished due to lack of oxygen, which is suitable for fighting fires in closed spaces, production equipment and containers.

When suffocating and extinguishing the fire in the fire field, the hole can be covered or blocked with incombustible or nonflammable materials such as asbestos quilt, wet sack, wet quilt, sand and foam. Fill the combustion area with steam and inert gas (such as carbon dioxide and nitrogen); Use the original doors on the building and the components on the production, storage and transportation equipment to close the combustion area to prevent air from entering.

3, isolation fire extinguishing method

Combustible is one of the most important combustion conditions. If the combustible is separated from the fire source or air, the combustion reaction will automatically stop. For example, by spraying fire extinguishing agent, combustible substances are isolated from air and heat, and foam generated by foam extinguishing agent covers the surface of burning liquid or solid, and combustible substances are isolated from flame and air. All these are isolated fire fighting methods.

There are many specific measures to isolate and extinguish the fire. For example, transfer flammable and explosive substances near the fire source to a safe place; Close the valve on the equipment or pipeline to prevent combustible gas and liquid from flowing into the combustion zone; Demolition of flammable building structures near the fire source to form a space area to prevent the fire from spreading.

4. Restrain fire extinguishing methods

Chemical extinguishing agents are sprayed into the combustion zone to participate in the combustion reaction, which stops the chain reaction of free radicals (combustion chain) and makes the combustion reaction stop or unsustainable. The fire extinguishing agent that can be used in this method includes dry powder and haloalkane fire extinguishing agent. When putting out the fire, we should accurately inject enough extinguishing agent into the combustion area to block the combustion reaction, and also take cooling measures to prevent re-ignition.

Fire safety extinguishing 10 stroke:

1. If you find a fire, shout loudly and quickly call the fire alarm number 1 19, explain the road name and house number clearly, and then send someone to meet the fire truck at the door.

2. Use local materials when putting out the fire, such as covering the flame with blankets and quilts, and then put out the fire. ?

3. Use pots, barrels and other water to put out the fire in time, and use floor fire-fighting equipment to put out the fire in time. ?

4, individual items on fire, to quickly move the fire to the outdoor fire fighting. ?

5. When the oil pan is on fire, cover the pan directly to put out the fire. ?

6. When household appliances catch fire, cut off the power supply first, and then cover the fire with blankets and quilts. If they are still not extinguished, water them again. ?

7. Use blankets and quilts when the TV is on fire. People should stand on the side to prevent the CRT from bursting and hurting people. ?

8, gas, liquefied gas stove is on fire, you must first close the valve, covered with apron, clothes, quilts, etc. After soaking, pour water and let it out. ?

9. When putting out the fire, slowly open the doors and windows, so as to avoid air convection accelerating the spread of the flame, and the flame suddenly jumps out and hurts people. ?

10. Evacuate combustible materials and liquefied gas tanks near the fire site to a safe place in time. ?
