What fire extinguishers should be used to extinguish Class A B C fires?

Hello, 51 Anju is at your service.

There are generally the following types of fires:

Class A fire: Solid matter fire. This substance is usually organic in nature and can produce scorching embers when burned.

Class B fires: fires of liquids or meltable solid substances.

Class C fires: Gas fires.

Class D fires: metal fires.

Class E fires: live fires. A fire in which an object burns with electricity.

Category F fire: Fire of cooking objects (e.g. animal and vegetable fats) in cooking utensils.

1.To extinguish Class A fires, that is, solid burning fires, water-type, foam, ammonium phosphate dry powder, and halide type fire extinguishers should be used.

2.Dry powder, foam, halide alkyl and carbon dioxide fire extinguishers should be used to extinguish Class B liquid fires and meltable solid matter fires.

3.Dry powder, halide alkyl and carbon dioxide fire extinguishers should be used to extinguish Class C fires, that is, gas-fired fires.

4.Halides, carbon dioxide, and dry powder fire extinguishers should be used to extinguish live fires.

5.To extinguish the fire of live equipment, the phosphoric acid salt dry powder and halide type fire extinguisher should be used.

6.For Class D fires, that is, metal burning fires, as far as the current situation in China is concerned, there is no finalized fire extinguisher product. At present, foreign fire extinguishers mainly include powdered graphite fire extinguishers and dry powder fire extinguishers for metal fires.

In the case that the production of fire extinguishers and fire extinguishing agent beads has not yet been finalized in China, dry sand or cast iron foam can be used to extinguish the fire.

7. Extinguish Class F fires with a pot lid or foam fire extinguisher.

Extinguishing polar solvents.

Chemical foam fire extinguishing agent shall not be used for Class B fire, and anti-soluble foam fire extinguishing agent shall be used.

Dry powder and carbon dioxide fire extinguishing agents should be used to extinguish Class C fires.

Class A fire: refers to a fire of solid matter. This substance tends to be organic in nature and generally produces hot embers when burned. Such as wood, coal, cotton, wool, hemp, paper and other fires.

Category B fires: Liquid fires and fires of meltable solid matter. Such as gasoline, kerosene, diesel, **, methanol.

Ethanol, bitumen, paraffin.

and other fires. Class C fire: refers to a gas fire. Such as coal gas, natural gas, methane.

Ethane, propane.

Hydrogen and other fires.

To extinguish Class A fires, you can choose water-type fire extinguishers, foam fire extinguishers, ammonium phosphate dry powder fire extinguishers, and halide fire extinguishers. Class A fire refers to the fire of solid matter, which often has the nature of organic matter, and generally produces hot embers when burned, such as wood, coal, cotton, wool, hemp, paper, etc.

Category B fires refer to fires of liquids or meltable solid substances, such as kerosene, diesel, **, methanol, ethanol, asphalt, paraffin, etc.

Class C fires refer to gas fires, such as gas, natural gas, methane, ethane, propane, hydrogen, etc., and Class D fires refer to metal fires, such as potassium, sodium, magnesium, titanium, zirconium, lithium, aluminum-magnesium alloys, etc.

Dry powder, foam, halide alkanes, carbon dioxide, etc. should be used to extinguish Class B fires, chemical foam fire extinguishers should not be used to fight water-soluble Class B fires, and dry powder, halide alkanes, and carbon dioxide fire extinguishers should be used to fight Class C fires.

Class A fire extinguishers should be used (water-type fire extinguishers, foam fire extinguishers, ammonium phosphate dry powder fire extinguishers, halide type fire extinguishers).

Class A fire: refers to a fire of solid matter. Such as hay, wood, cotton, wool, hemp, paper, etc., such substances often have the nature of organic substances, and generally produce scorching embers when burned. According to the combustion characteristics of the substance, fires can be divided into six categories: A, B, C, D, E, and F.

Category B fires: Liquid fires and fires of meltable solid matter. Such as gasoline, kerosene, diesel, **, methanol, ethanol, asphalt, paraffin and other fires.

Class C fire: refers to a gas fire. Fires such as gas, natural gas, methane, ethane, propane, hydrogen, etc.

Category D fire: refers to a metal fire. Such as potassium, sodium, magnesium, aluminum-magnesium alloy and other fires.

Class E fire: refers to the fire of live objects and precision instruments and other substances. Class F fires:

Fire of cooking products (e.g. animal and vegetable fats) in cooking utensils.

The correct way to use the fire extinguisher

1. Foam fire extinguisher: upside down, swing left and right when used, so that the agent is mixed, and the foam containing carbon dioxide gas is sprayed out under pressure.

2. Carbon dioxide fire extinguisher: When in use, pull out the first plug of the insurance, hold the front grip of the horn nozzle, and press down the grip switch to spray out the internal high-pressure gas.

3. Dry powder fire extinguisher: remove the seal when using, pull out the safety pin, and press the handle of the nozzle pipe towards the fire point to spray out.

Fire extinguisher: Pull out the pin and press down the handle.

If you accidentally cause a fire in daily life, you need to use a fire extinguisher to extinguish the fire, but there are many popular types of fire extinguishers on the market, and the purpose of each fire extinguisher is different. Let's take a look. 1. What fire extinguisher should be used to extinguish Class A fire refers to the fire caused by the combustion of substances containing organic properties, such as:

Hay, paper, coal, cotton, wool, hemp, wood, etc. When a class A fire occurs, foam fire extinguishers or water-type fire extinguishers can generally be used to extinguish fires, alkyl halide fire extinguishers can also be used to extinguish, and ammonium phosphate dry powder fire extinguishers can be used to extinguish fires. 2. What are the fire fighting methods 1. If the circuit is on fire at home, then the power supply should be cut off first, and then a wet towel or a dry powder fire extinguisher or a gas fire extinguisher should be used to extinguish the fire at the location of the circuit.

Do not directly use water to extinguish the fire, otherwise it is easy to cause a short circuit in the circuit or cause a phenomenon such as **. If the TV catches fire, then you should extinguish the fire from the side of the TV to avoid the TV suddenly injuring yourself. 2. If the oil pan fire in the kitchen is on fire, then as long as the lid of the oil pan is directly covered, the fire in the oil pan can be suffocated and extinguished.

Be careful not to use water to extinguish the fire, otherwise it will make the fire in the pan even bigger. 3. If the gas or liquefied gas stove is on fire in the kitchen, then the gas or liquefied gas stove should be turned off first, and then a wet cloth or wet blanket should be used to cover the flames, and then quickly remove the gas cylinders, oil cylinders and other items that are easy to burn or ** to avoid the expansion of the fire. 4. If the furniture is on fire, then the fire should be extinguished with water first, if it cannot be extinguished, then the fire hydrant should be opened, so that the fire hydrant can be put out with more water, and at the same time, the items that are easy to burn or ** next to the furniture should be removed to avoid the expansion of the fire.

The above is a detailed introduction to what fire extinguishing equipment and fire fighting methods should be used to extinguish Class A fires, and I hope it can help you fight fires in time. The types of fires can generally be divided into five types, and the fire extinguishers used in each fire are different, so it is important to distinguish the types of fires.
