ABC dry chemical fire extinguisher is suitable for, what kind of fire is abc dry chemical fire extin

Dry chemical fire extinguishers.

It can extinguish general fires, and can also extinguish fires caused by the combustion of oil and gas. Dry chemical fire extinguishers are made using carbon dioxide.

Gas or nitrogen gas is used as a power to spray the dry powder in the cylinder to extinguish the fire.

Dry powder is a dry, easy-to-flow fine solid powder, composed of a base material that can extinguish fires and additives such as moisture-proof agents, flow accelerators, and anti-caking agents. It is mainly used to extinguish flammable liquids such as petroleum and organic solvents.

Initial fires of flammable gases and electrical equipment.

Class A is a solid fire, Class B is a liquid fire, Class C is a gas fire, Class D is a metal fire, and Class E is an electrical fire. Then ABC dry powder fire extinguisher is suitable for solid, liquid and gas fires.

Therefore, ABC dry powder fire extinguisher is suitable for extinguishing Class A, Class B and Class C fires, and can also be used to extinguish general live fires.

Portable dry powder fire extinguisher, also known as ABC fire extinguisher, is suitable for three types of disasters: Class A fire, Class B fire, and Class C fire.

1. Class A fire: refers to the fire of burning carbon-containing solid combustibles, such as wood, flour, wool, hemp, paper, etc.

2. Class B fire: fire burning of nails, B and C liquids, such as gasoline, kerosene, methanol, ethanol, acetone, etc.

3. Fire extinguisher fire of class C fire: to combustible gas, such as gas, natural gas, methane, hydrogen, etc.

ABC dry powder fire extinguisher is suitable for the following three types of fire extinguishing: the first type is solid fire extinguishing, which refers to the fire caused by the combustion of solid combustibles containing carbon, that is, wood, flour, wool, hemp, paper, etc. The second category is liquid fire extinguishing, which is a fire that burns nails, B and C liquids, such as gasoline, kerosene, methanol, ethanol, acetone, etc.

The third category is gas fire extinguishing, such as coal fires caused by combustible gases such as gas, natural gas, methane, hydrogen, etc.

ABC dry powder fire extinguisher: ABC dry powder fire extinguisher is filled with ammonium phosphate dry powder fire extinguishing agent, which is composed of inorganic salt with fire extinguishing effect and a small amount of dry powder fire extinguishing agent that are dried, crushed and mixed into fine solid powder. ABC dry powder fire extinguisher can extinguish Class A, B, and C fires.

Among them, Class A fires refer to fires caused by the combustion of ordinary solid combustibles, such as wood, flour, wool, hemp, paper and grain, synthetic fibers, synthetic plastics, synthetic rubber, etc.;

Class B fire refers to the fire caused by the combustion of all flammable liquids, such as gasoline, kerosene, methanol, ethanol, acetone, etc.;

Class C fires are fires caused by gases, such as gas, natural gas, methane, hydrogen, and other combustible gases.

ABC dry powder fire extinguisher, also known as rolling, is a multi-functional fire extinguisher, the fire extinguishing agent is ammonium phosphate salt, which can extinguish solid fires (Class A fire), liquid fires and meltable solid fires (Class B large car fire), combustible gas fire (Class C virtual fire), live fire (Class E fire).

ABC dry chemical fire extinguisher means a fire extinguisher that can extinguish type A, type B, type C fire and electric fire.

Class A fires are caused by carbon solid combustibles, such as wood, cotton, wool, etc., Class B fires are caused by A, B, and C liquids, such as gasoline, kerosene, methanol, etc., and Class C fires are caused by combustible gases, such as gas, natural gas, formaldehyde, etc.

ABC dry powder fire extinguisher refers to a dry powder fire extinguisher that can extinguish Class A, Class B and Class C fires, with a wide range of applications, but shall not be used to extinguish light metal material fires.

Dry powder fire extinguishers use carbon dioxide gas or nitrogen gas as the power to spray out the dry powder in the cylinder to achieve the purpose of extinguishing the fire.

Before using the fire extinguisher, it is necessary to check whether the dry powder fire extinguisher is within the shelf life and whether it is within the normal pressure range.

In general, the relevant safe use period will be indicated on the bottle and inspection card of the fire extinguisher.

To check the pressure range, the pointer mainly looks at the pressure gauge pointer range, the pointer in the yellow range indicates that the pressure of the fire extinguisher is sufficient, green means that the pressure is normal, and red indicates the underpressure.

Please click to enter ** to describe the correct use of the fire extinguisher.

The steps to use the fire extinguisher are:

looking, lifting, pulling, aiming, pressing; That is, to see if the pressure gauge is corrected normally, lift the fire extinguisher, pull off the safety pin, aim at the root of the flame, and press down the handle.

The fire extinguisher and fire hydrant should be checked and maintained regularly to be normal and effective, and the fire extinguisher will cause air leakage and decompression due to sun and rain, and it will malfunction and affect the extinguishing during emergency use.

When using a foam fire extinguisher, care should be taken that the person should stand upwind and try to get as close to the source of the fire as possible, because its spray distance is only 2 3 meters, and it should be sprayed from the side where the fire is most dangerous, and then gradually move, being careful not to leave sparks.

Hold the wooden handle of the nozzle in your hand to avoid frostbite. Because the content of carbon dioxide in the air is too much, it is also bad for the human body, so in the case of unobstructed air, it should be ventilated immediately after spraying.

There are two types of carbon dioxide fire extinguishers: on-off type and gate return hall knife type.

When using, first remove the safety pin, then hold the wooden handle on the jet horn with one hand, press the duck tongue switch or rotary switch with the other hand, and finally hold the body.

It should be noted that once the knife fire extinguisher is opened, it can no longer be turned off. Therefore, be prepared before using it.

ABC dry powder fire extinguisher refers to the fire that can extinguish Class A, Class B, Class C and electric fire, and the carbon dioxide fire extinguisher can extinguish Class B, Class C and electric fire.

Class A fire: refers to the fire of burning carbon-containing solid combustibles, such as wood, cotton, wool, linen, paper, etc.

Class B fire: Nails, B and C liquids, such as gasoline, kerosene, methanol, ether, acetone, etc.

Class C fire: refers to the fire of combustible gas, such as gas, natural gas, methane, acetylene, hydrogen, etc.

Class D fire: refers to the fire of combustible metals, such as potassium, sodium, magnesium, titanium, zirconium, lithium, aluminum-magnesium alloys, etc.

Charged fire: Refers to a fire in which a live object burns.

1. Class A refers to solid fire extinguishing. It refers to fires caused by the burning of solid combustibles containing carbon, i.e., paper, wood, hemp, flour, wool, etc.
