What are the types of fire extinguishers, and what are the 5 types of fire extinguishers?

There are two types of fire extinguishers.

According to its mode of movement, it can be divided into: portable type and cart type; According to the power of driving the fire extinguishing agent, it can be divided into: gas cylinder type, pressure storage type, chemical reaction type; According to the fire extinguishing agent filled, it can be divided into: foam, dry powder, halide alkane, carbon dioxide, clean water, etc.

Fire extinguisher. There are many types (three main categories): According to the way they move, they can be divided into:

According to the fire extinguishing agent filled, it can be divided into: foam, dry powder, halide alkane, carbon dioxide.

Acid, alkali, water, etc.

Chemicals are hidden in fire extinguishers to extinguish fires. Fire extinguishers are one of the common fire prevention devices and are stored in public places or places where fires may occur. Because of its simple and portable design, it can also be used by ordinary people to extinguish small fires that have just broken out.

Different types of fire extinguishers contain different ingredients and are designed for different fire alarms. Care must be taken when using it to avoid counter-effects and dangers.

1. Aerosol fire extinguisher:

1. Its small size, cold and high temperature resistance, easy to carry, non-toxic, non-conductive, fast fire extinguishing speed, micro-residue, free of annual inspection and maintenance, adults and children can be used, can be used at any time within the validity period, combined with aerosol generator and chemical self-coolant, using the heat and power generated by the reaction of aerosol generator to send the high-efficiency fire-extinguishing particles (microparticles: chemicals that cannot be seen with the eye) into the fire to extinguish the fire, so as to achieve the effect of fire extinguishing.

Portable aerosol fire extinguisher has a wide range of fire extinguishing, suitable for solid surface fire, gas fire, electrical fire, edible oil fire, liquid fire, in portability, safety and fire extinguishing ability than traditional fire extinguishers are more prosperous, compared with the previous fire extinguishers, it is more suitable for vehicle and household use, will not cause secondary pollution to the environment, fire extinguishing speed is also fast.

2. How to use aerosol fire extinguishers.

First of all, you need to take out the fire extinguisher, which can be done with both left and right hands, because it is portable, small and lightweight.

The second step is to pull open the tail safety ring and pull it out.

The third step is to aim the nozzle of the fire extinguisher, press the spray button, and automatically spray it, and spray it left and right according to the fire situation to quickly extinguish the fire.

Fire extinguishing scope: wood solid surface fire, electrical fire, kitchen waste oil fire, combustible liquid fire, metal fire can be extinguished;

2. Dry powder fire extinguisher:

1. The dry powder pressure storage fire extinguisher (portable type) is powered by nitrogen to press out the dry powder in the cylinder. It is suitable for extinguishing fires of petroleum products, paints and organic solvents. It inhibits the chain reaction of combustion and extinguishes the fire.

It is also suitable for extinguishing liquid, gas, and electrical fires (dry powder has electrical insulation properties of more than 50,000 volts). Some can also extinguish solid fires.

Pay attention to the maintenance of the fire extinguisher, and put it in a good place, dry and ventilated. Check whether the dry powder is agglomerated twice a year, and replace it in time if there is a clumping; Check the weight of the agent once a year, if it is less than the specified weight or look at the pressure gauge to drop the air pressure, it should be filled in time.

2. When the dry powder trolley is used, first quickly push the trolley fire extinguisher to the near fire source, pull out the jet hose and straighten it, pull out the safety pin, open the straightening door handle, aim at the root of the flame, make the powder mist sweep the key flame, pay attention to cutting off the fire source, control the flame to return, and push forward to extinguish the fire from near and far.

3. Dry powder fire extinguisher (MFZ) has an effective range of 2-3kg, a range of 4-5kg is 4m, and the time is 8-9 seconds. The 8kg range is 5m, the time is 12 seconds. (MFTZ) 35-50kg cart has an effective range of 8m and a time of 20 seconds.

The 70kg cart has a range of 9m and a time of 25 seconds.

3. Carbon dioxide fire extinguisher.

Carbon dioxide fire extinguishers are used as fire extinguishing agents to extinguish the carbon dioxide gas stored in the high-pressure gas cylinder, carbon dioxide does not leave a trace after extinguishing the fire, suitable for extinguishing valuable instruments and equipment, archives, computer room fires, it is not conductive and is also suitable for extinguishing live low-voltage electrical equipment and oil fires, but it can not be used to extinguish potassium, sodium, magnesium, aluminum and other material fires.

dry chemical fire extinguishers; carbon dioxide gas fire extinguishers; Water-based fire extinguishers.

Dry powder and foam fire extinguishers.

Summary. Hello dear and happy to answer for you. <>

There are 5 types of fire extinguishers. 1. The carbon dioxide fire extinguisher uses liquid carbon dioxide as the fire extinguishing device, which needs to be pressurized first and then sprayed out when used, so that the fire can isolate the air, so as to achieve the purpose of fire extinguishing, and can be used for archives and electrical equipment below 600 volts. 2. The foam fire extinguisher uses sodium bicarbonate and aluminum sulfate as refrigerants, and the fire extinguisher needs to be turned upside down when used, so that the two substances are fully mixed to produce foam, and finally sprayed out, which has a wide range of use, but cannot be used to extinguish live equipment.

3. The internal fire extinguishing agent of the water-based fire extinguisher is to stir the surfactant and pure water, and the tank is in a liquid form, but after spraying, it will become a water mist, which can quickly evaporate the heat in the fire field and form a water film to achieve the purpose of extinguishing the fire. 4. Water-type fire extinguisher The fire extinguisher is filled with water-forming foam fire extinguishing agent and nitrogen, which can play a double fire extinguishing effect, and has a long validity period, which can be used to extinguish both solid and liquid initial disasters. 5. There are two situations of dry powder fire extinguisher, one is an ordinary dry powder fire extinguisher, which has a large particle surface area and limited fire extinguishing ability, and the other is an ultra-fine dry powder fire extinguisher, which has a small internal particle surface area, so the fire extinguishing efficiency is higher.

There are five types of fire extinguishers: foam fire extinguishers, acid and alkali fire extinguishers, carbon dioxide fire extinguishers, halide fire extinguishers, and dry powder fire extinguishers. Acid-base fire extinguishers, like foam fire extinguishers, cannot be used to extinguish water-soluble fires. The halide fire extinguishing agent mainly achieves the purpose of extinguishing the fire by inhibiting the chemical reaction process of combustion and interrupting the combustion.

There are 5 types of fire extinguishers, namely foam fire extinguishers, acid and alkali fire extinguishers, carbon dioxide fire extinguishers, halide fire extinguishers, and dry powder fire extinguishers. According to its mode of movement, it can be divided into: portable type and cart type;

Foam fire extinguishers are suitable for extinguishing lipids, petroleum products, etc., but not for water-soluble fires. Acid-alkali fire extinguishers, like foam fire extinguishers, cannot be used to extinguish water-soluble fires, and acid-alkali fire extinguishers are suitable for extinguishing solid initial fires.

Carbon dioxide fire extinguishers are used to reduce oxygen content, and Tan Shi causes suffocation in the burning area and extinguishes the fire. The halide fire extinguishing agent mainly inhibits the chemical reaction process of combustion, so that the combustion is interrupted to achieve the purpose of fire extinguishing.

What are the 5 types of fire extinguishers?

1. Volatile liquid fire extinguisher.

It is mainly used to extinguish large flames such as electrical fires.

2. Water agent fire extinguisher.

It is mainly used for fires caused by wood or cloth.

3. Carbon dioxide fire extinguisher.

Although this fire extinguisher can be used to extinguish many types of fire scenes, it is not suitable for use in fires caused by oil stoves or some fires that are less indiscriminate.

4. Foam fire extinguisher.

It contains two containers, each containing two different liquids, and when the two hungry liquids are mixed, a large amount of foam will be produced, thus extinguishing the fire.

5. Dry powder fire extinguisher.

This fire extinguisher is mainly used for fires caused by liquid or electricity, it contains a fine powder inside, and after spraying, it can have the effect of extinguishing the fire.

Precautions when using fire extinguishers

1. When you use a fire extinguisher, the first thing you need to pay attention to is its time problem, especially the fire extinguisher that has not been used for a long time, to see if it is still within the shelf life, if it has passed the shelf life, you can not continue to use it, otherwise it will be dangerous.

2. In the process of using the fire extinguisher, we have to open the spray gun and take out the spray tape, at this time we should pay attention when we take out the spray tape, and we must make the spray tape smooth so that it can not be knotted.

3. In the process of using the fire extinguisher, we also need to pay attention to the operation requirements, and must follow the prescribed standards, and the spray gun of the fire extinguisher can not be aimed at the people around you, of course, it cannot be aimed at yourself, otherwise it is easy to be dangerous.

Hello, I have helped you find the result; Fire extinguishers are common fire-fighting equipment, and there are many types of fire extinguishers according to different fire extinguishing media and suitable stove places. Common types of fire extinguishers include:1

Dry chemical fire extinguishers: Dry chemical fire extinguishers are suitable for extinguishing gas, liquid and solid fires. The fire extinguishing agent is a dry powder, which can prevent the continuous combustion of the flame and achieve the effect of extinguishing the fire.

Dry chemical fire extinguishers have a wide range of applications and are commonly found in commercial, industrial and domestic places. 2.Foam fire extinguisher:

Foam fire extinguishers are suitable for extinguishing fires in liquids and solids, such as paints, solvents and greases. Foam fire extinguishers can form a layer of foam on the surface of the fire, weakening the burning ability of the flame and consuming the oxygen of the fire source to extinguish the fire. 3.

Carbon dioxide fire extinguisher: Carbon dioxide fire extinguisher is suitable for extinguishing electrical equipment and liquefied gas fires. The carbon dioxide fire extinguisher has a forced throat impact force, which can quickly extinguish the fire when extinguishing the fire and avoid secondary damage to the fire extinguishing site.

4.Water fire extinguisher: Water fire extinguisher is suitable for extinguishing solid substances such as wood and cloth and water-soluble liquid fires.

Water extinguishers are water-repellent, quickly cooling the fire source and surrounding objects and quelling the fire. In addition, there are other types of fire extinguishers such as dry powder foam composite fire extinguishers, chemical dry powder fire extinguishers, liquid ammonium chloride fire extinguishers, etc. When using a fire extinguisher, it is necessary to select and operate according to the fire situation and the specific type of fire extinguisher to give full play to its fire extinguishing effect.
