How many types of fire extinguishers are currently used in water plants?

Nowadays, it is inevitable that various fires will occur due to human activities. Therefore, it is particularly important to learn to understand the different types of fire extinguishers, and to choose the right fire extinguisher for different fire types. What I want to say here is to distinguish fire extinguishers according to the type of fire extinguishing agent corresponding to common fires.

Generally, according to the different fire extinguishing agents, it can be divided into: dry powder fire extinguisher, carbon dioxide fire extinguisher, water-based fire extinguisher, Class D fire extinguisher, foam fire extinguisher, etc.

Tools Raw materials.

ABC dry chemical fire extinguisher.

CO2 fire extinguisher.

Water-based fire extinguishers.

Metal D-type fire extinguisher.

Foam fire extinguisher for water machine.

Method steps.

ABC dry powder fire extinguisher: It can effectively extinguish most solid, liquid, gaseous, and live equipment fires. The efficiency of dry powder fire extinguishers for extinguishing solid surface fires in life is high, and the dry powder fire extinguisher has a wide range of applications, is affordable, suitable for most places to configure, and is suitable for family equipment, factory workshops, office buildings, rental houses, etc.

The fire extinguishing agent of dry powder fire extinguisher has many dust particles, and it is not suitable for places where dust prevention is required.

Carbon dioxide fire extinguisher: not used to extinguish solid fires, suitable for liquid and gas fires. Fire on live equipment below 600V.

It is generally believed that if the voltage is too high, the use effect of carbon dioxide fire extinguishers will be reduced. When using a carbon dioxide fire extinguisher, beware of suffocation in an enclosed space, and hold the non-metallic part of the horn with human hands to avoid frostbite when operating the carbon dioxide fire extinguisher (carbon dioxide vaporizes and absorbs heat, so it will cause the temperature of the cylinder to drop sharply). Carbon dioxide is suitable for valuable libraries, dust-free workshops, computer rooms, equipment rooms, and power distribution rooms.

Precautions. When using a fire extinguisher, pay attention to personal safety.

When the fire is large, you should wait for a professional fire brigade to extinguish the fire.

Do not use expired fire extinguishers, fire extinguishers that are obsolete by national law.

1.Foam fire extinguisher: make the BAI upside down, swing left and right, mix the agent, and produce foam containing carbon dioxide gas to be sprayed out under pressure. dao

2.Carbon dioxide fire extinguisher: When in use, pull out the safety pin, hold the front grip of the horn nozzle, and press 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 tube towards the fire point to spray out.

4.1211 fire extinguisher: Pull out the plug and press down the handle.

The types of water-based fire extinguishers mainly include clean water fire extinguishers and foam fire extinguishers.

1) Clean water fire extinguisher.

It is mainly used to extinguish solid fires, that is, Class A fires, such as wood, paper, cotton and linen fabrics, etc.

2) Foam fire extinguisher.

It is mainly used to extinguish Class B fires, such as gasoline, kerosene, diesel, benzene, toluene, xylene, vegetable oil, animal fat, etc. It can also be used for solid Class A fires, such as wood, bamboo, paper, cotton and linen fabrics. Anti-solvent foam fire extinguishers can also extinguish water-soluble, flammable, and combustible liquid fires.

Foam fire extinguishers are not suitable for extinguishing live equipment fires, Class C gas fires, and Class D metal fires.

The water mist type can extinguish the fire.

1.Dry chemical fire extinguisher: suitable for extinguishing electrical, oil, gas and solid matter fires, it is one of the most common fire extinguishers.

2.Carbon dioxide fire extinguisher: suitable for extinguishing electrical, oil and gas fires, the fire extinguishing effect is better, but you need to pay attention to safety when using.

3.Foam fire extinguisher: suitable for oil extinguishing and solid matter fire, the fire extinguishing effect is better, but you need to be careful not to spray foam to electrical appliances and other easily conductive objects when using.

4.Water fire extinguisher: suitable for extinguishing fires of solid substances such as wood and paper, but not suitable for extinguishing electrical, oil and gas fires.

It is necessary to pay attention to the fact that different types of fires need to use different types of fire extinguishers, and the appropriate fire extinguishers should be selected according to the actual situation, and they should ensure their own safety before extinguishing the fire to avoid accidents.

General fires can be extinguished by water-type fire extinguishers, bubble type foam type fire extinguishers, dry powder type fire extinguishers, carbon dioxide (CO2) type, active emulsifier (AR) type or other special special rescue machinery and equipment for special purposes. Water is the most commonly used method of general extinguishing and can directly pour a large amount of water onto a large amount of flame that is formed. However, for small-scale open flames and early hidden flames, foam or dry powder should be used to extinguish them.

The foam has a very good covering performance, which can form a protective film to cover the flame and prevent it from spreading around; The dry powder has a strong adsorption effect, which can quickly adsorb each of the flames so that it will no longer be conducted.

Generally, fires can be extinguished by foaming fire extinguishers, dry powder fire extinguishers or gas fire extinguishers. Among them, the foam fire extinguisher is suitable for various fire fighting places in fire towns, dry rooms, factories, warehouses, shopping malls, offices and homes; Dry powders and gases are suitable for places that are more harmful to electrical equipment. In addition, there are some special situations that will also be used in different ways to extinguish, such as the chemical Yujian Cave is susceptible to water vapor and can easily cause a large amount of steam.

Generally, fires can be extinguished by using water-type fire extinguishers, foam-type spine extinguishers, or dry powder fire extinguishers. The water-type is the most common, they can effectively reduce the temperature of incinerable substances and can effectively inhibit the spread of incinerable substances. Foam is also a good choice for Sakura, as it can coat it with flammable substances, thus reducing its flammability.

In addition, the dry powder type is also a good choice, as it can quickly draw out the oxygen from the incinerable substance, so that it can heal.

In general, fires can be extinguished using water, foam and dry powder fire extinguishers. Water-type fire extinguishers are the most common, which can be used to extinguish slag and rescue general flammable materials. Foam fire extinguishers are mainly used to extinguish flammable materials caused by solid materials; The dry powder type is for fire protection against volatile flames or harmful gases. Therefore, in general, fires can be extinguished using water, foam or dry powder extinguishers.

The types of fires are generally as follows:

Class A fire: Solid matter fire.

Class B fires: Liquid-li-zi closed bodies or meltable solid matter fires.

Class C fires: gas fires.

Class D fires: metal fires.

Class E fire: live fire.

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

1.To extinguish Class A fires, water-type wax, foam, and ammonium phosphate dry powder should be used to extinguish fires.

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

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

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

5.Ammonium phosphate dry powder and halide fire extinguishers should be used to extinguish Class E fires.

6.Foam fire extinguishers should be used to extinguish Class F fires.

There are many types of fire extinguishers, which can be divided into foam, dry powder, halides, carbon dioxide, clean water and other fire extinguishers according to the fire extinguishing agent filled. Among them, foam fire extinguishers are suitable for extinguishing general Class B fires, such as oil products, grease and other fires, and can also be applied to Class A fires.

Dry powder fire extinguishers are suitable for flammable, combustible liquids, gases and live equipment for initial disasters.

Carbon oxide fire extinguishers are mainly used to extinguish the initial disaster of valuable equipment, archives, instruments, electrical equipment below 600 volts and oil. Clean water fire extinguishers are suitable for extinguishing solid material fires.

In addition, water-based fire extinguishers can extinguish electrical fires up to 36kV. Water-based foam fire extinguishers are suitable for extinguishing flammable solid or liquid initial disasters, and are widely used in oil fields, oil depots, ships, factories, shops and other places.

The green tank is generally a water-based fire extinguisher.

Water-based fire extinguishers, substances such as surfactants, the main ingredients of the chemicals, and treated pure water are stirred. It exists in liquid form, so it is referred to as a water-based fire extinguisher.

After spraying, the water-based (water mist) fire extinguisher becomes a water mist, instantly evaporates a large amount of heat from the fire, quickly reduces the temperature of the fire, inhibits thermal radiation, and the surfactant quickly forms a layer of water film on the surface of the combustible, isolating oxygen, cooling and isolating the dual effects, and at the same time participates in fire extinguishing, so as to achieve the purpose of rapid fire extinguishing.

Specific Applications:

It is suitable for extinguishing flammable solid or liquid initial disasters, and is widely used in oil fields, oil depots, ships, factories, shops and other places.

The water-type fire extinguisher is equipped with AFFF water-forming foam fire extinguishing agent and nitrogen, which has the advantages of simple operation, high fire extinguishing efficiency, no need to be inverted when used, long validity period, anti-re-ignition, double fire extinguishing, etc., and can extinguish the initial disaster of combustible solid and liquid, and is a must-have for the development, processing, storage and transportation of wood and bamboo, fabrics, paper and oil substances.
