What is the best place to put out a fire extinguisher
Aim at the root of the fire source.
Common methods of using fire extinguishers
1. Foam fire extinguisher is suitable for fighting general fires, such as oil products, grease and other fires that cannot be rescued by water. Fires with water-soluble flammable and flammable liquids cannot be extinguished, such as alcohol, ester, ether, ketone and other material fires, and cannot be used to extinguish fires of live equipment. When not reaching the fire source, remember not to tilt or move it. When the fire source is about 10 meters away, pull out the safety plug, then turn the fire extinguisher upside down, hold the lifting ring with one hand, and hold the bottom ring of the cylinder with the other hand, aiming at the root of the fire source and spraying.
2. The dry powder fire extinguisher can extinguish general fires and fires caused by combustion of oil and gas. It is mainly used to extinguish the initial fires of flammable liquids, combustible gases and electrical equipment such as petroleum and organic solvents. The method of use is to pull out the safety bolt, shake it up and down a few times, stand upwind according to the wind direction, aim at the root of the flame, hold the pressure bar in one hand, and hold the nozzle in one hand to extinguish the fire.
3. Carbon dioxide fire extinguisher, used to extinguish the initial fire of books, archives, valuable equipment, precision instruments, electrical equipment below 600 volts and oil. It is suitable for extinguishing fires such as oil products, grease, etc., but it cannot extinguish fires of water-soluble flammable and flammable liquids, such as alcohol, esters, ethers, ketones and other substances. It can not extinguish live equipment and Class C and D fires.
Do not incline the fire extinguisher excessively before use, and do not take it horizontally or upside down to prevent the two agents from mixing and spraying out in advance. When using, pull out the safety bolt, turn the cylinder upside down, hold the lifting ring with one hand, and hold the bottom ring of the cylinder with the other hand, aim the jet at the burning object, and press the handle to extinguish the fire.

When selecting a fire extinguisher, the following requirements should be met:
1. For fire extinguishing of Class A, e79fa5e98193e4b893e5b19e31333431346438 should use water type, foam, dry powder, halogenated fire extinguishers, etc .;
2. Dry powder, foam, halogenated alkane, carbon dioxide, etc. should be selected for firefighting Class B fires, and chemical foam fire extinguishers should not be used for firefighting Class B fires;
3. Dry powder, halogenated alkane, carbon dioxide type fire extinguishers should be selected for the suppression of Class C fires;
4. Fire extinguishers with halogenated alkane, carbon dioxide and dry powder should be selected for fire fighting of live equipment;
5. Dry powder and halogenated fire extinguishers should be used to fight fires of A, B, C, and live equipment;
6. Special dry powder fire extinguishers should be selected for fighting Class D fires.

The best location of the fire extinguisher:
1. Use in upwind position: where the wind passes first, then it is called upwind position;
2. The distance from the fire source: about 1.5-3 meters, to ensure that the fire extinguishing agent is sprayed on the fire material, and can effectively extinguish the fire;
3. There are no flammables, explosives, dangerous goods, away from the power supply, etc. around the fire extinguishing location;
Use methods and precautions of fire extinguishers Use methods and precautions of fire extinguishers
There are many types of fire extinguishers, suitable for extinguishing different types of fires, and the methods of use are also different. Common ones are:
(1) Portable foam fire extinguisher
The foam fire extinguisher is suitable for extinguishing the first fire of oil and general substances.
When in use, hold the lifting ring of the fire extinguisher with your hands and carry it to the fire site steadily and quickly. Do not carry it horizontally.
When extinguishing the fire, hold the lifting ring in one hand and the bottom edge of the barrel with the other hand, turn the fire extinguisher upside down, aim the nozzle at the fire source, and shake it vigorously a few times to extinguish the fire.
note:
Do not point the cover and bottom of the fire extinguisher to the human body to prevent the cover and bottom from popping out and injuring people.
Do not spray with water at the same time, so as not to affect the fire extinguishing effect.
When extinguishing electrical fires, try to cut off the power first to prevent personnel from getting an electric shock.
(2) Portable carbon dioxide fire extinguisher
Carbon dioxide fire extinguishers are suitable for extinguishing the initial fire of precision instruments, electronic equipment and electrical appliances below 600 volts.
There are two ways to use portable carbon dioxide fire extinguishers, namely handwheel and duckbill.
Handwheel: Hold the handle of the spray gun in one hand, tear off the lead seal in the other, turn the handwheel counterclockwise, turn on the switch, and the carbon dioxide gas will be sprayed out.
Duckbill: Hold the handle of the spray gun in one hand, pull out the safety pin in the other, and press down the duckbill on the handle to extinguish the fire.
Note:
When extinguishing the fire, personnel should stand upwind.
The hand holding the spray barrel should be held at the gel nozzle to prevent frostbite.
After indoor use, ventilation should be strengthened.
(3) Portable dry powder fire extinguisher
The dry powder fire extinguisher is suitable for extinguishing the first fire of oil, combustible gas and electrical equipment.
When in use, first open the safety pin, hold the nozzle in one hand, aim at the fire source, and pull the pull ring with the other hand to extinguish the fire source.
The best location for extinguishing with a fire extinguisher:
1. Use in upwind position: where the wind first passes, then it is called upwind position.
2. The distance from the fire source: about 1.53 meters, to ensure that the fire extinguishing agent is sprayed onto the flaming substance, which can effectively extinguish the fire. It should be aligned with the strongest part of the flame and the root of the flame and move up, down, left and right. If conditions permit, the user can carry the fire extinguisher and spray along the four sides of the burn.
3. There are no flammables, explosives, dangerous goods, away from the power supply, etc. around the fire extinguishing location.
4. The fire extinguisher is a portable fire extinguishing tool. Chemicals are placed in the fire extinguisher to extinguish the fire. Fire extinguishers are one of the common fire protection facilities. They are stored in public places or places where fire may occur. The composition of different types of fire extinguishers is different. They are designed for different fire alarms. Care must be taken during use to avoid adverse effects and danger.
