An auto fire extinguisher, also known as an automatic fire suppression system, is a device designed to detect and suppress fires in commercial or industrial settings without human intervention. This type of system can be triggered by various sensors that detect changes in temperature, smoke, or heat.   There are several types of auto fire extinguishers: 1. Smoke Detectors: These systems use photoelectric or ionization sensors to detect smoke. When the sensor detects smoke, it triggers an alarm and activates the extinguishant. 2. Heat Detectors: Heat detectors respond to rising temperatures before smoke appears. They can be set at different sensitivity levels, depending on the potential for high-temperature fires. 3. Combination Detectors: These systems combine both smoke and heat detection to provide more reliable fire detection. 4. Sprinkler Systems: Sprinklers are activated when the temperature in a specific area exceeds a predetermined level, typically through a heat-sensitive element in the sprinkler head. 5. Gas Systems: These systems release an inert gas, such as nitrogen or carbon dioxide, to smother the fire. They are commonly used in computer server rooms, electrical panels, and other enclosed spaces where fire suppression is critical. 6. Dry Pipe Systems: Similar to sprinkler systems, these system s contain pressurized air until a fire is detected. Once the fire is detected, a valve opens, allowing water to flow into the pipes and extinguish the fire. 7. Wet Pipe Systems: Water flows continuously through the pipes, ready to extinguish any fire upon detection. 8. Preaction Systems: These systems have a pressure switch on the water supply line to each sprinkler head. When the fire is detected, the switch releases the water, which then activates the sprinkler heads. It's very important that ensuring auto fire extinguishers regularly maintained and tested to function correctly during emergencies. This includes checking wearing sign, extinguishant, and all components.  

A fire extinguisher is a device used to put out fires. They are designed to expel a fire-suppressing agent in order to extinguish or control a fire. There are different types of fire extinguishers suitable for different kinds of fires: Portable Powder Fire ExtinguisherDifferent Types 1. PowderExtinguishers: These are used on Class A (wood, paper, fabric), Class B (flammable liquids), and Class C (electrical) fires. 2. Water Extinguishers: These are typically used on fires involving ordinary combustibles like paper, wood, and cloth. 3. Foam Extinguishers: These are used on fires involving flammable liquids like gasoline, diesel, or oil. 4. Carbon Dioxide (CO2) Extinguishers: These are used on electrical fires, as well as fires involving flammable liquids and combustible metals. Operation Method To use a fire extinguisher, you typically follow these steps: - Shake the extinguisher to ensure the powder mixes well. - Point the nozzle at the base of the fire. - Aim at fire scource and press the lever to release the extinguishant. - Scan the area after the fire is out to ensure it does not reignite. Note: If you are not familiar with operation of the fire extinguisher, call the fire emergency service immediately

 Working principle for CO2 Fire Extinguishser The liquid CO2 stored in the fire extinguisher quickly transforms into a gas when it is released, absorbing large amount of heat in the process, thereby reducing the temperature at the fire site. At the same time, the release of carbon dioxide will reduce the oxygen concentration in the air, or even eliminate it completely, thus cutting off the contact between the fuel and the oxygen, so that the flame is extinguished due to lack of oxygen. In addition, the density of carbon dioxide is about 1.5 times that of air, which makes it able to effectively surround the burning object when extinguishing the fire, or distribute in a more confined space, further enhancing its suffocation effect. Application Scenario for CO2 Fire Extinguisher Carbon dioxide fire extinguishers are suitable for a variety of fire types, including books, high accuracy measurement devices, oil, gas, and live electric. Advantages During the fire extinguishing process, carbon dioxide does not cause pollution to the environment, nor does it cause corrosion or damage to the fire area  

There are differences in functions and uses between fire-fighting facilities and fire-fighting equipment. Fire-fighting equipment refers to equipment used for fire extinguishing, fire prevention and fire accidents, including fire extinguishers, fire hydrants, water hoses, water guns, demolition tools, etc. Fire protection facilities refer to automatic fire alarm systems, fire hydrant systems, automatic fire extinguishing systems, smoke prevention and exhaust systems, emergency broadcasting, emergency lighting, and safe evacuation facilities. Although fire-fighting facilities and fire-fighting equipment are both used for fire safety, they have certain differences in functions and uses. (1) Firefighting equipment refers to equipment used for fire extinguishing, fire prevention and fire accidents, mainly including fire extinguishers, fire hydrants, water hoses, water guns, demolition tools, etc. Among them, fire extinguishers can be divided into five categories according to the fire extinguishing agent they are filled with. ①Dry powder fire extinguisher. ②Carbon dioxide fire extinguisher. ③Water-based fire extinguishers (including water fire extinguishers and foam fire extinguishers). ④Clean gas fire extinguisher (such as haloalkane type fire extinguisher). Fire extinguishers can be divided into three categories based on the type of pressure that drives the fire extinguisher. ① Gas storage type fire extinguisher refers to a fire extinguisher in which the fire extinguishing agent is driven by the pressure of compressed gas or liquefied gas released from the gas storage bottle on the fire extinguisher. ② Pressure-storage fire extinguisher refers to a fire extinguisher in which the fire extinguishing agent is driven by the pressure of compressed gas or fire-extinguishing vapor in the same container of the fire extinguisher. ③Chemical reaction fire extinguisher refers to a fire extinguisher in which the fire extinguishing agent is driven by the gas pressure generated by the chemical reaction in the fire extinguisher. (2) Fire protection facilities refer to automatic fire alarm systems, fire hydrant systems, automatic fire extinguishing systems, smoke prevention and exhaust systems, emergency broadcasts, emergency lighting, and safe evacuation facilities, etc. In general, fire-fighting facilities are a broad concept that includes a variety of equipment systems required for fire fighting, while fire-fighting equipment is specific equipment used for fire extinguishing and fire prevention.

Explosion-proof tanks are important equipment that can effectively protect against the shock waves and fragments generated when explosives explode, as well as the damage caused by surrounding people. It has been widely used in explosion-proof safety inspections such as armed police, public security, civil aviation, customs, and ports. department. Today I will introduce to you how to operate an explosion-proof tank.   1. After transporting the explosion-proof tank to the destination, open the lid and put the explosion-proof tank into working condition.   2. Put the suspicious explosives into the explosion-proof tank, select OFF, and pull the limit handle with your hand. The lid of the explosion-proof tank will automatically focus and be in the locked position. The explosion-proof tank should be moved to a safe place for operation.   3. After moving the handle to a safe place, ask the staff to evacuate and take out the suspicious objects from the explosion-proof tank. At this time, pull the opening handle by hand to detach the compression spring from the cover hook, and the self-weight of the cover makes it move along the axis of the tank. Move downward and the cover is fully opened; suspicious objects can be removed from the explosion-proof tank with special tools.   4. When it is necessary to destroy explosives, the detonator or detonating charge and wire can be inserted through the hole of the destruction device to connect them to the explosives, allowing all surrounding personnel to evacuate to a safe area before detonating them.   5. The destruction device is specially used to destroy explosives. The detonator and wire can be inserted through the hole, and the device will automatically press down and lock.   6. After one or more explosions occur when using an explosion-proof tank, if one of the following conditions is found, the tank can no longer be used: cracks and holes; obvious deformation of the tank body; explosion-proof cover or flange The bulge is greater than two millimeters; the gap between the explosion-proof cover and the tank is greater than five millimeters.   7. Remove debris from the tank and pressure relief cover in a timely manner to ensure cleanliness.   8. Regularly oil the moving parts of the tank to prevent rust.

Carbon dioxide fire extinguishing agent is a fire extinguishing agent with a history of more than 100 years. It is cheap, easy to obtain and prepare. It mainly relies on suffocation and partial cooling to extinguish fires. Carbon dioxide has a higher density, about 1.5 times that of air. Under normal pressure, liquid carbon dioxide will vaporize immediately. Generally, 1kg of liquid carbon dioxide can produce about 0.5 cubic meters of gas. Therefore, when extinguishing a fire, carbon dioxide gas can exclude air and surround the surface of burning objects or be distributed in a relatively closed space, reducing the oxygen concentration around combustibles or in protective spaces, causing a suffocation effect to extinguish fires. In addition, when carbon dioxide is ejected from the storage container, it will quickly vaporize from liquid to gas, absorbing part of the heat from the surroundings and playing a cooling role. Carbon dioxide fire extinguishers are fire extinguishers that use filled liquid carbon dioxide to extinguish fires. It is composed of cylinder, bottle valve, injection system and other components. Divided into: (1) Portable carbon dioxide fire extinguishers. The total weight is less than or equal to 28kg, and there are four specifications: 2kg, 3kg, 5kg, and 7kg; (2) Trolley-type carbon dioxide fire extinguisher. The total weight is greater than 28kg, and its specifications are 20kg and 25kg. Carbon dioxide fire extinguishers are suitable for extinguishing initial fires involving various flammable liquids and flammable gases. As well as fires in live equipment, precision electronic instruments, and valuable equipment. However, it should not be used outdoors when there is strong wind. After use in a narrow and enclosed space, ventilation or personnel must be evacuated from the site in time to prevent suffocation. When pressurizing, liquid carbon dioxide is compressed into a small cylinder, and then sprayed out when extinguishing a fire, which has the effect of cooling and isolating the air. Carbon dioxide fire extinguishers are mainly used to extinguish initial fires of valuable equipment, archives, instruments, electrical equipment below 600 volts and oil. It has excellent properties such as good fluidity, high injection rate, non-corrosion to containers and non-deterioration. It is used to extinguish initial fires in books, files, valuable equipment, precision instruments, electrical equipment below 600 volts and oil. Suitable for extinguishing Class B fires (such as kerosene, diesel, crude oil, methanol, ethanol, asphalt, paraffin, etc.) Suitable for extinguishing Class C fires (such as coal gas, natural gas, methane, ethane, propane, hydrogen, etc.) Class E fires (fires in which electrified objects burn).

When using a carbon dioxide fire extinguisher, if it is used outdoors, you should choose to spray in the upwind direction, and place your hand on the wooden handle of the cylinder to prevent frostbite. If it is used in a small space indoors or outdoors, the operator should leave quickly after extinguishing the fire to prevent suffocation. Cart-type dry powder fire extinguishers and portable dry powder fire extinguishers are suitable for fires and how to use them: Sodium bicarbonate dry powder fire extinguisher is suitable for initial fires of flammable and combustible liquids, gases and electrical equipment; ammonium phosphate dry powder fire extinguishers can not only be used for the above types of fires, but also can extinguish initial fires of solid materials. But none of them can put out metal burning fires. When putting out a fire, you can quickly run to the fire scene with a handheld or shoulder-carrying fire extinguisher, and put down the fire extinguisher about 5 meters away from the burning place. If you are outdoors, you should choose to spray in the upwind direction. If the dry powder fire extinguisher used is an external pressure storage type, the operator should hold the spray gun firmly with one hand and lift the opening handle on the gas storage bottle with the other hand. If the gas storage bottle is opened by a hand wheel, turn it counterclockwise, rotate it to the highest position, and then lift the fire extinguisher. When the dry powder is sprayed out, quickly aim at the root of the flame and sweep. If the dry powder fire extinguisher used has a built-in gas storage bottle or a pressure storage type, the operator should first remove the safety pin on the opening handle, then hold the nozzle at the front end of the spray hose, and use the other hand to open the pressure handle Press down and open the fire extinguisher to put out the fire. When using a fire extinguisher with a spray hose or a pressure-storage fire extinguisher, the handle should always be depressed with one hand and cannot be released, otherwise the spray will be interrupted. When using a dry powder fire extinguisher to extinguish flammable or flammable liquid fires, you should aim at the main part of the flame and spray. If the liquid fire being extinguished is flowing and burning, you should aim at the root of the flame from near to far, and spray from left to right until all the flames are extinguished. If a flammable liquid is burning in the container, users should aim at the root of the blaze and rock it to mow, so that the sprayed dry powder flow covers the entire container opening. When the blaze is driven out of the container, the user should continue to spray until the blaze is extinguished. . When extinguishing a flammable liquid fire in a container, care should be taken not to aim the nozzle directly at the liquid surface to prevent the impact of the jet from causing the flammable liquid to splash out and expand the fire, making it difficult to extinguish the fire. If a flammable liquid burns in a metal container for too long and the wall temperature of the container is higher than the self-ignition point of the flammable liquid, it will easily cause re-ignition after extinguishing the fire. If used in conjunction with a foam fire extinguisher, the fire will be extinguished. Better results. When using an ammonium phosphate dry powder fire extinguisher to extinguish a solid combustible fire, the spray should be aimed at the most violent burning point and sweep up, down, left and right. If conditions permit, the user can hold the fire extinguisher and spray it while walking around the burning object, so that the dry powder fire extinguishing agent can be sprayed evenly on the surface of the burning object until the flame is completely extinguished. Cart-type foam fire extinguisher adapts to fires and usage methods: Its adaptability to fires is the same as that of portable chemical foam fire extinguishers. Instructions for use: When used, it is usually operated by two people. First, quickly push and pull the fire extinguisher to the fire scene, and stop it 10 meters away from the fire point. After one person releases the spray hose, he holds the spray gun with both hands and aims at the burning area; the other First, turn the handwheel counterclockwise to raise the screw to the highest position to fully open the bottle cap. Then tilt the cylinder backward to make the pull rod touch the ground, and rotate the valve handle 90 degrees to spray foam to extinguish the fire. If the valve is installed at the spray gun, the person responsible for operating the spray gun should open the valve. The fire extinguishing methods and precautions are basically the same as those of portable chemical foam fire extinguishers, so you can refer to them. Since this type of fire extinguisher has a long spray distance and a long continuous spray time, it can give full play to its advantages and be used to extinguish initial fires in large-area storage tanks or oil tankers. When using a cart-type fire extinguisher, point the back of it toward the fire source (it should be placed in the upwind direction outdoors), first remove the spray gun, unfold the powder outlet pipe (remember not to twist it), and then lift the air inlet lever to allow carbon dioxide to enter Storage tank, when the gauge pressure rises to 0.7 MPa ~ 1 MPa, lower the air intake pressure rod to stop air intake. At this time, turn on the switch, spray dry powder, and put out the fire from near to far. For example, when fighting an oil fire, do not let the dry powder air flow directly hit the oil stain to avoid splashing the oil surface and spreading the fire.

The trolley storage pressure ABC dry powder fire extinguisher is equipped with ammonium phosphate dry powder fire extinguishing agent and nitrogen. It is suitable for extinguishing initial fires of flammable solids, flammable liquids, flammable gases and electrical equipment. Widely used in factories, warehouses, ships, gas stations, distribution rooms, vehicles and other factories. Cart-type carbon dioxide fire extinguishers are generally operated by two people. When using them, two people push or pull the fire extinguisher to the burning place, stop it about 10 meters away from the burning object, and one person quickly removes the horn and unfolds the spray hose, then holds For the handle at the base of the horn, another person quickly turns the handwheel counterclockwise and turns it to the maximum position. The fire extinguishing method is the same as the portable method. Principle: Rapidly lower the temperature of combustibles and isolate them from the air. Advantages: When extinguishing fire, it will not leave any traces and damage the items, so it can be used to extinguish books, files, valuable equipment and precision instruments, etc.

1. Overview of wet fire extinguishers Wet fire extinguisher is a common fire-fighting equipment suitable for various places, such as residences, public places, offices, etc. The fire extinguisher is mainly composed of a water pump, a pressure tank, a nozzle, a valve and other components. Its working principle is to spray water and a special foam mixture onto the fire source to form a covering layer, making it difficult for the fire source to contact oxygen and eventually be extinguished. 2. Working principle of wet fire extinguisher The working principle of wet fire extinguishers is based on foam fire extinguishing technology. After mixing foam and water, foam liquid is formed through pressure, vibration and other means, and then the foam liquid is sprayed to the fire scene to extinguish the source of the fire and prevent the spread of the fire. During use, the wet fire extinguisher must first pump out the water in the pressure tank, then pump the water into the pipeline through the pressure release valve, transport it from the pipeline to the nozzle, and mix with air to form foam. After the foam is obtained, the nozzle begins to spray The foam liquid quickly covers the entire burning area, reducing the temperature of the burning area and quickly extinguishing the fire source. 3. Application scenarios of wet fire extinguishers Wet fire extinguishers are widely used in various indoor places, such as residences, shopping malls, hospitals, schools, etc. Especially in places that are flammable and explosive, such as chemical warehouses, pharmaceutical factories, etc., wet fire extinguishers should be used to extinguish fires. In short, wet fire extinguishers are common fire-fighting equipment that can effectively extinguish fire sources and protect people's lives and property. When using it, you need to pay attention to its usage method and prevent misoperation to avoid unnecessary losses.

Wet fire extinguisher is a common fire extinguishing equipment. Its working principle is as follows: Water supply: Wet fire extinguishers mainly rely on water supply for fire extinguishing. Generally speaking, wet fire extinguishers are connected to the building's automatic water supply system to ensure an adequate and continuous supply of water. Pressure control: There is a pressure control system inside the wet fire extinguisher to maintain the pressure of water inside the fire extinguisher. Typically, this control system includes a pressure switch and a pressure regulator to ensure water is sprayed out quickly when needed. Trigger mechanism: When a fire occurs, the wet fire extinguisher will be automatically triggered. This is usually accomplished via a fire detector or manual switch. Once the trigger mechanism is activated, water is released into the fire extinguisher's nozzle, ready to spray. Sprinkler system: Wet fire extinguishers have sprinkler heads located in areas where fires are likely to occur, usually on the ceiling. When water is released into the sprinkler head, it passes through a specially designed nozzle, creating an even spray pattern. This spray pattern sprays water evenly over the fire, creating a mist that cools and extinguishes the flames. Fire extinguishing effect: Wet fire extinguishers mainly extinguish fires in two ways, namely reducing the temperature of the fire source and inhibiting flame combustion. When water is sprayed onto a fire, it absorbs the heat released by the flame, thereby lowering the temperature of the fire. In addition, the formation of water vapor can inhibit the burning of the flame and reduce the surrounding area of the fire source.

1. Water fire extinguisher. It refers to a fire extinguisher whose cylinder is filled with clean water and uses carbon dioxide or nitrogen as the driving gas. There are generally two specifications: 6L and 9L. The fire extinguisher containers contain 6L and 9L of water respectively. 2. Water-based foam fire extinguisher. Aqueous film-forming foam fire extinguishing agents (AFFF) are generally used and fire extinguishers use nitrogen as the driving gas. Aqueous film-forming foam fire extinguishing agent can quickly form a layer of water film on the surface of hydrocarbon substances that can inhibit its evaporation. It relies on the dual effects of foam and water film to quickly and effectively extinguish fires. It is an updated product of chemical foam fire extinguishers. 3. Water-based water mist fire extinguisher. It is a high-tech, environmentally friendly fire extinguisher that improves the fire extinguishing efficiency by adding a small amount of organic or inorganic substances to the water to improve the fluidity, dispersion, wetting and adhesion properties of the water. Water-based water mist fire extinguishers have the advantages of being green and environmentally friendly (the agent is 100% biodegradable after fire extinguishing and will not cause pollution to surrounding equipment and space), highly efficient flame retardant, strong resistance to re-ignition, fast fire extinguishing speed, and strong permeability.

When using a portable fire extinguisher, it is best to operate it alone. You should hold the handle of the portable fire extinguisher and rush to the fire quickly. Put down the fire extinguisher about 5 meters away from the fire point (when using it outdoors, it should be in the windward direction), and unplug the fuse. Pin (do not point the head of the fire extinguisher towards the human body to prevent it from ejecting and injuring people), hold the front end of the spray belt with one hand, and press the handle firmly with the other hand, and the fire extinguishing agent will spray out from the nozzle. 1. When using a fire extinguisher to extinguish a stray liquid fire, you should spray from the side of the flame, aim at the root of the flame, and sweep from near to far, left and right, and advance quickly until the flame is completely extinguished. 2. When using a fire extinguisher to put out a flammable liquid fire in a container, you should also aim at the root of the flame from the side of the flame and sweep left and right. When the flame is driven out of the container, move forward quickly to extinguish all remaining fire. When extinguishing a fire, be careful not to point the nozzle directly at the liquid surface to prevent the impact of the fire extinguishing agent from splashing the oil, causing the fire to expand and making it difficult to extinguish the fire. 3. When using a fire extinguisher to put out a solid material fire, you should aim the fire extinguisher nozzle at the most violent burning point, spray left and right, and try to spray the dry powder fire extinguishing agent evenly on the surface of the burning object until the fire is completely extinguished. When using a fire extinguisher, be sure to always keep it upright during the fire extinguishing process. Do not use it lying down or upside down, otherwise it will not spray normally.

1. Water-based fire extinguishers emerged in the 1980s and have a physical fire extinguishing mechanism. The agent can form and expand a thin water film on the surface of combustible materials to isolate the combustible materials from the air and achieve fire extinguishing. Through the atomizing nozzle, fine water mist is sprayed out, which spreads over the fire field and evaporates heat, quickly reducing the temperature of the fire field, and at the same time reducing the concentration of oxygen in the air in the combustion zone to prevent re-ignition. Good re-ignition resistance is an unparalleled advantage of water-based fire extinguishers. 2. In addition to fire extinguishing, water-based fire extinguishers can also be used for self-rescue in fire scenes. When a fire breaks out, spray the agent in a water-based fire extinguisher on your body and apply it on your head to completely protect 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. It has a long validity period, is resistant to re-ignition, and has double fire extinguishing. It will not pollute the surface of the body after extinguishing the fire. It is less corrosive and is suitable for more sophisticated instruments and equipment.

Dry powder fire extinguishing agent is a dry and easy-flowing fine powder used for fire extinguishing. It is composed of inorganic salts with fire extinguishing effects and a small amount of additives that are dried, crushed, and mixed to form a fine solid powder. It is a fire extinguishing agent widely used in firefighting and is mainly used in fire extinguishers. In addition to special dry powder chemical fire extinguishing agents for extinguishing metal fires, dry powder fire extinguishing agents are generally divided into two categories: BC dry powder fire extinguishing agents and ABC dry powder. Such as sodium bicarbonate dry powder, modified sodium salt dry powder, potassium salt dry powder, ammonium dihydrogen phosphate dry powder, diammonium hydrogen phosphate dry powder, phosphoric acid dry powder and amino dry powder fire extinguishing agent. Dry powder fire extinguishing agents mainly extinguish fires through the physical and chemical effects that occur when the powder mist sprayed under the action of pressurized gas contacts and mixes with the flame: First, the volatile decomposition products of the inorganic salts in the dry powder react chemically with the free radicals or active groups generated by the fuel during the combustion process and have side-catalytic effects, interrupting the combustion chain reaction and extinguishing the fire; Second, the dry powder powder falls outside the surface of the combustible material, undergoes a chemical reaction, and forms a glass-like covering layer under the action of high temperature, thereby isolating oxygen and suffocating the fire. In addition, there is partial dilution of oxygen and cooling effects.

When using a dry powder fire extinguisher to extinguish flammable or flammable liquid fires, you should aim at the main part of the flame and spray. If the liquid fire being extinguished is flowing and burning, you should aim at the root of the flame from near to far, and spray from left to right until all the flames are extinguished. If a flammable liquid is burning in the container, users should aim at the root of the blaze and rock it to mow, so that the sprayed dry powder flow covers the entire container opening. When the blaze is driven out of the container, the user should continue to spray until the blaze is extinguished. . When extinguishing a flammable liquid fire in a container, care should be taken not to aim the nozzle directly at the liquid surface to prevent the impact of the jet from causing the flammable liquid to splash out and expand the fire, making it difficult to extinguish the fire. If a flammable liquid burns in a metal container for too long and the wall temperature of the container is higher than the self-ignition point of the flammable liquid, it will easily cause re-ignition after extinguishing the fire. If used in conjunction with a foam fire extinguisher, the fire will be extinguished. Better results. When a portable dry powder fire extinguisher is suitable for extinguishing a fire, you can quickly rush to the fire scene with the fire extinguisher in your hand or on your shoulder, and put down the fire extinguisher about 5 meters away from the burning place. If you are outdoors, you should choose to spray in the upwind direction. If the dry powder fire extinguisher used is an external pressure storage type, the operator should hold the spray gun firmly with one hand and lift the opening handle on the gas storage bottle with the other hand. If the gas storage bottle is opened by a hand wheel, turn it counterclockwise, rotate it to the highest position, and then lift the fire extinguisher. When the dry powder is sprayed out, quickly aim at the root of the flame and sweep. If the dry powder fire extinguisher used has a built-in gas storage bottle or a pressure storage type, the operator should first remove the safety pin on the opening handle, then hold the nozzle at the front end of the spray hose, and use the other hand to open the pressure handle Press down and open the fire extinguisher to put out the fire. When using a fire extinguisher with a spray hose or a pressure-storage fire extinguisher, the handle should always be depressed with one hand and cannot be released, otherwise the spray will be interrupted. When using a portable dry powder fire extinguisher to extinguish a solid combustible fire, the spray should be aimed at the most violent burning point and sweep up, down, left and right. If conditions permit, the user can hold the fire extinguisher and spray it while walking around the burning object, so that the dry powder fire extinguishing agent can be sprayed evenly on the surface of the burning object until the flame is completely extinguished. The barrel of the portable dry powder fire extinguisher is made of high-quality carbon steel and processed with special technology.
