What kind of fire can be extinguished by water based fire extinguishers, water based fire extinguish

The water mist type can extinguish the fire.

Water-based fire extinguishers are mainly suitable for fighting the initial disasters of solid or non-water-soluble liquids, and are essential for fire fighting in the development, processing, storage and transportation of wood and bamboo, fabrics, paper and oil substances. Among them, water-based water mist fire extinguishers can also extinguish fires with live equipment.

The fire extinguishing principle is a foam produced by AFFF water film-forming foam fire extinguishing agent and nitrogen inside, which is sprayed to the surface of the fuel, and the water precipitated by the foam layer forms a layer of water film on the surface of the fuel, so that the combustibles are isolated from the air.

The advantages include easy operation, high fire extinguishing efficiency, no need to be inverted when used, long validity period, anti-re-ignition, double fire extinguishing and so on. The state advocates the use of water-based fire extinguishers, which are more environmentally friendly. However, ordinary water-based fire extinguishers cannot extinguish fires caused by ordinary household appliances, and water-based fire extinguishers of water mist type must be used.

How to use portable water-based fire extinguishers

When using a portable fire extinguisher, it is best to operate it alone, should carry the handle of the portable fire extinguisher, quickly rush to the fire, put down the fire extinguisher at a distance of about 5 meters from the ** point (when used outdoors, it should occupy the upwind direction), pull out the safety pin (do not put the head of the fire extinguisher against the human body to prevent it from popping out and hurting people), hold the front end of the spray belt with one hand, and press down the pressure handle with the other hand, and the fire extinguishing agent will be sprayed out of the nozzle.

1. When using a fire extinguisher to extinguish a liquid fire, it should be sprayed from the side of the flame, aimed at the root of the flame, and swept from near to far, left and right, and quickly advanced until the flame is completely extinguished.

2. When using a fire extinguisher to extinguish the fire of the combustible liquid in the container, it should also aim at the root of the flame from the side of the flame and shoot left and right. When the flame is driven out of the container, move forward quickly and extinguish all embers. When extinguishing the fire, care should be taken not to spray the nozzle directly at the liquid level, so as to prevent the impact of the fire extinguishing agent from splashing the oil and expanding the potential, resulting in difficulty in extinguishing the fire.

3. When using a fire extinguisher to extinguish a solid material fire, the nozzle of the fire extinguisher should be aimed at the most violent place of burning, and the dry powder fire extinguishing agent should be evenly sprayed on the surface of the burning material as far as possible until the fire is completely extinguished.

When using a fire extinguisher, it should be noted that it should always be kept upright during the fire extinguishing process, and should not be used horizontally or upside down, otherwise it will not be sprayed normally.

Summary. Hello dear, water-based fire extinguisher is a common type of fire extinguisher, which mainly extinguishes the fire by spraying water mist or water flow, which can effectively reduce the temperature of the surface of the combustible object and absorb heat energy, so as to control and extinguish the flame. Because water-based fire extinguishers are non-toxic, non-polluting, and low-cost, they are widely used in many occasions, such as offices, shops, schools, hotels and other places, as well as automobiles, boats and other means of transportation.

Hello, water-based fire extinguishers are mainly suitable for Class A fires, i.e., combustible solid materials such as wood, paper, celery, cloth, etc. Since water-based fire extinguishers spray water, they are not suitable for fires such as electrical equipment, oil, and gas. When using water-based fire extinguishers, it is necessary to pay attention to the use method and distance of the fire extinguisher to avoid injury to personal safety.

Hello, water-based fire extinguisher is a common type of firearm, mainly by spraying water mist or water flow to extinguish the fire, which can effectively reduce the temperature of the surface of the combustible and absorb heat energy, so as to control and extinguish the flame. Because water-based fire extinguishers have the characteristics of non-toxic, non-polluting, and low cost, they are widely used in many occasions, such as offices, shops, schools, hotels and other places, as well as automobiles, boats and other means of transportation.

The scope of application of water-based fire extinguishers is:It is suitable for fighting flammable solid or liquid initial disasters, and is widely used in oil fields, oil depots, ships, factories, shops and other places, and is a necessary fire-fighting equipment to prevent fires and protect people's lives and property.

The water-type fire extinguisher is equipped with AFF water film foam extinguishing agent and nitrogen. It has the advantages of simple operation, high fire extinguishing efficiency, no need to flip during use, long duration, anti-re-ignition, double fire extinguishing and so on. It is capable of extinguishing initial fires of flammable solids and liquids.

It is a firefighting facility necessary for the development, processing, storage and transportation of wood, cloth, paper and oil.

Portable water-based fire extinguishers are different from traditional fire extinguishers and are available in red, yellow, and green. The top and bottom of the bottle of the portable water-based fire extinguisher also have nano polymer materials, which can emit light at night, so that the fire extinguisher can be found as soon as possible at night.

The advantages of water-based fire extinguishers are:

1. Water-based fire extinguishers emerged in the eighties of the last century and belong to the physical fire extinguishing mechanism. The agent can form and extend a thin film of water on the surface of combustibles, isolate combustibles from the air, and extinguish fires.

Through the atomization nozzle, a fine water mist is sprayed, which spreads the fire field and evaporates the heat, rapidly reducing the temperature of the fire site, and at the same time reducing the concentration of oxygen in the air in the combustion area to prevent re-ignition. It has good re-ignition resistance and is an incomparable advantage of water-based fire extinguishers.

2. In addition to fire extinguishing, water-based fire extinguishers can also be used for fire self-rescue. When **, spray the agent in the water-based fire extinguisher on the body and apply it to the head, which can completely exempt yourself from flame damage in ordinary fires and minimize burns in high-temperature fires.

3. The water-based fire extinguisher does not need to be inverted when used, has a long validity period, is resistant to re-ignition, and double-fire extinguishing, will not pollute the surface of the body after extinguishing the fire, and is less corrosive and suitable for more sophisticated instruments and equipment.

Summary. Hello dear, water-based fire extinguishers are mainly suitable for extinguishing the initial disaster of solid or non-water-soluble liquids. It is widely used in oil fields, oil depots, ships, factories, shops and other places, and is a necessary fire-fighting equipment to prevent fires and protect people's lives and property.

Fire extinguishers are one of the common acorns for fire extinguishers, which are stored in public places or places where fires may occur. Care must be taken when using it to avoid counter-effects and dangers. The world's first fire extinguisher was built in 1834, when a fire almost completely destroyed the old Palace of Westminster, where the British Parliament building is located.

Water-based fire extinguishers are mainly suitable for extinguishing initial fires of flammable solids or non-water-soluble liquids.

Water-based fire extinguishers can be used to extinguish the initial disasters of solid and liquid, and are essential for fire fighting in the mining, processing and storage of wood and bamboo, weaving and masking objects, paper and oil. In addition, water-based fire extinguishers can also be used to extinguish fires with live equipment and fire self-rescue.

Types of water-based fire extinguishers:

At present, water-based fire extinguishers are mainly divided into three types, namely: water-based foam fire extinguishers, water-based water mist fire extinguishers and water-based clean water fire extinguishers.

The difference between the three fire extinguishers and the containment device:

1. Water-based foam fire extinguisher.

It can be used to extinguish solid or liquid fires, such as oil fields, factories and shops, and is an essential firefighting equipment to prevent fires. Water-based fire extinguishers have the advantages of easy operation, high fire extinguishing efficiency, long validity period and double fire extinguishing.

2. Water-based water mist fire extinguisher.

It was not until 08 that water-based water mist fire extinguishers became popular in China. It is not only green and environmentally friendly, but also will not cause pollution to the device and space, strong re-ignition resistance, fast fire extinguishing, which is incomparable to other fire extinguishers.

3. Water-based water fire extinguisher.

The fire extinguishing agent is mainly clean water, with low viscosity and high thermal stability at room temperature, which can be regarded as an ancient and widely used fire extinguisher, and is easy to obtain and store. <>

Water-based fire extinguishers are mainly suitable for extinguishing solid and liquid initial disasters.

Water-based fire extinguishers are essential for firefighting in the mining, processing, and storage of wood, bamboo, fabric, paper and oil. Water-based fire extinguishers are mainly divided into three types, namely: water-based foam fire extinguishers, water-based water mist fire extinguishers, and water-based clean water fire extinguishers.

Among them, water-based water mist fire extinguishers are not only environmentally friendly, but also suitable for extinguishing fires on live equipment, so they are very suitable for household use.

The fire extinguisher mechanism of water-based fire extinguishers is the principle of physical fire extinguishers. The fire extinguishing agent is mainly composed of hydrocarbon surfactant, fluorine cracking circular carbon surfactant, flame retardant and additives. The fire extinguishing agent has a penetrating effect on Class A fires, such as wood, cloth, etc., and the fire extinguishing agent can penetrate the inside of combustibles, even if the fire is large and cannot be completely extinguished.

Precautions for using water-based fire extinguishers

1. When using it early, you should first mention the fire extinguisher to the first place, put down the fire extinguisher, pull out the safety pin, hold the handle at the root of the horn barrel with one hand, and hold the pressure handle of the opening and closing valve with the other hand. For water-based fire extinguishers without a jet hose, the horn should be pulled up 70-90 degrees.

2. When using, wear gloves when using to avoid touching the spray cartridge and jet hose to prevent frostbite.

3. When using water-based fire extinguishers outdoors, you must pay attention to the wind direction, and you should choose to spray the fire at the upwind outlet. If you are using a water-based fire extinguisher in a small space, you should evacuate the crowd first, as excessive water-based fire extinguishers can suffocate to death.
