Pay attention when using a carbon dioxide fire extinguisher

CO2 fire extinguisher.

What to pay attention to when using.

Carbon dioxide fire extinguishers are common firefighting tools in our daily life, because the design of carbon dioxide fire extinguishers is simple and portable, and ordinary people can also use them to extinguish small fires that have just occurred, so they are widely used, so what matters need to be paid attention to when using carbon dioxide fire extinguishers? Today, I will give you a detailed explanation of some matters to be paid attention to in the use of carbon dioxide fire extinguishers. Carbon dioxide fire extinguisher 1 open-air fire extinguisher is not effective in extinguishing fire when there is wind.

2. Before spraying, the safety device should be removed and then the pressure handle should be pressed. 3. Because the effective spray distance of the carbon dioxide fire extinguisher is small, it should not be too far away from the fire source when extinguishing the fire, and it is generally better to be about 2 meters. 4. Do not touch the metal part with your hands when spraying to prevent frostbite.

5. After spraying in a small confined space or underground tunnel, people should be withdrawn immediately to prevent suffocation. 6. When the fire extinguisher is stored, it is strictly forbidden to be close to the heat source or the sun, check it regularly, and check whether the carbon dioxide gas leaks with the weight of a well-known person. The above is the need to pay attention to the use of carbon dioxide fire extinguishers, generally when there is no fire, we do not abuse carbon dioxide fire extinguishers, and check whether the carbon dioxide fire extinguishers are damaged on schedule, I hope to help you.

What are the precautions for carbon dioxide fire extinguishers?

1. When using, you need to pull out the safety pin before pressing the handle.

2. When in use, spray the nozzle towards the bottom of the flame.

3. When using, try to avoid contact between the spray cartridge and the hose, otherwise it is easy to be injured, and at the same time, when fighting the fire, if the voltage exceeds 600 volts, the power should be cut off and then the fire should be extinguished.

What are the advantages and disadvantages of carbon dioxide fire extinguishers.

1. Advantages. Because carbon dioxide is a gas, it can quickly diffuse into the air after use, and will not cause damage to the burning objects, especially like electrical appliances, books, etc., and if it is a dry powder fire extinguisher, it will inevitably form a secondary loss, in addition, the fire extinguishing effect of this product is also very high, suitable for a small range of fire, very easy to extinguish.

2. Disadvantages. For this kind of products, a high concentration is required, so the level of fire extinguishing is relatively low, suitable for use in some relatively compact areas, and when the carbon dioxide concentration accounts for 2% of the air concentration, there will be some unpleasant odors, and when the concentration reaches 7 9%, it will make people feel difficult to breathe, reaching 10% and above, people will lose consciousness.

There is liquid carbon dioxide in the bottle, and when the handle of the bottle valve is pressed, the carbon dioxide inside will be shot out from the siphon through the bottle valve to the nozzle, so that the consistency of oxygen in the combustion zone will decrease rapidly, and when the carbon dioxide reaches a sufficient concentration, the flame will be extinguished.

Because the foam sprayed by the foam fire extinguisher contains a lot of water, it is not as good as the carbon dioxide liquid fire extinguisher, which does not pollute the substance and leaves no traces after extinguishing the fire. It can be used to extinguish fires caused by the burning of wood, cotton, etc., and can also extinguish fires of flammable liquids such as oil.

Scope of use of air foam fire extinguisher:

The extinguishing agent in this type of fire extinguisher is air foam liquid. According to the different types of air foam fire extinguishing agents, air foam fire extinguishing agents can be divided into protein foam fire extinguishers, fluoroprotein foam fire extinguishers, water film-forming, foam fire extinguishers and anti-solvent foam fire extinguishers. It is mainly suitable for extinguishing the initial fire of flammable liquid substances such as gasoline, kerosene, diesel, vegetable oil, grease, etc.

Precautions for carbon dioxide foam fire extinguishers:

1. When using, do not directly grasp the outer wall of the horn barrel and the metal connecting pipe with your hands to prevent your hands from being frostbitten.

2. The fire extinguisher should be kept upright during the spraying process, and should not be used flat or upside down;

3. When extinguishing a liquid fire, spray the CO2 fire extinguishing agent from near to far.

4. If the combustible liquid is sprayed from the upper part of one side of the container to the burning container when burning in the container, the CO2 jet cannot be used to directly impact the combustible surface.

5. When using CO2 outdoors to extinguish fires, it should be sprayed in the upwind direction.

6. When used in a narrow indoor space, the operator should leave quickly after use to prevent suffocation and poisoning.

It can be used to extinguish the initial disaster of combustible solid substances such as wood, cotton, paper, etc. For the initial fire of polar flammable liquids such as methanol, ether, acetone, etc., only the anti-soluble air foam fire extinguisher can be used to extinguish it.

1. How to use: first pull out the safety pin, then press the pressure handle, and aim the nozzle at the root of the flame to spray.

2. Precautions: When using, try to prevent frostbite caused by direct contact with the spray cartridge and jet hose. When extinguishing an electrical fire, if the voltage exceeds 600 volts, remember to cut off the power supply before extinguishing the fire.

A carbon dioxide fire extinguisher uses the liquid carbon dioxide filled to spray out a fire extinguisher. It is composed of cylinders, bottle valves, injection systems and other components. Divided into:

1) Portable CO2 fire extinguisher. The total weight is less than or equal to 28kg, and its specifications are 2kg, 3kg, 5kg, and 7kg;

2) Cart type carbon dioxide fire extinguisher. The total weight is more than 28kg, and its specifications are 20kg and 25kg. Carbon dioxide fire extinguishers are suitable for extinguishing all kinds of flammable liquids and combustible gases.

as well as fires of live equipment and precision electronic instruments and valuable equipment. However, it should not be used outdoors when it is windy, and after being used in a narrow and confined space, it is necessary to ventilate or evacuate the scene in time to prevent suffocation.

When using carbon dioxide fire extinguishers, you should first understand the characteristics and uses of carbon dioxide fire extinguishers, which are mainly used to extinguish fires in electrical and electronic products and precision instruments, valuables and archives. Precautions for use: First, use the fire extinguisher correctly, second, to prevent frostbite, and touch the nozzle and metal pipe fittings with your bare hands strictly when using. Third, to prevent carbon dioxide suffocation, it is necessary to ventilate in time, or the body is in a low environment for a long time to engage in fire extinguishing work.

1. Books, archives, valuable equipment, precision instruments, electrical equipment below 600 volts and oil fires. It is suitable for fighting Class B fires (such as kerosene, diesel, **, methanol, ethanol, asphalt, paraffin, etc.);

2. Suitable for fighting Class C fires (such as gas, natural gas, methane, ethane, propane, hydrogen, etc.);

3. Extinguish Class E fires (fires in which objects are burned with electricity).

Carbon dioxide fire extinguishing agent is a fire extinguishing agent with a history of more than 100 years, which is inexpensive, easy to obtain and prepare, and mainly relies on asphyxiation and partial cooling to extinguish fires.

The correct way to use a CO2 fire extinguisher is as follows:

Tools Material: CO2 fire extinguisher, fire source.

1. Take out the carbon dioxide fire extinguisher, hold the bottom of the bottle with one hand and the handle with the other, place the fire extinguisher on the ground, and tilt the sprinkler head down 45 degrees.

2. Remove the safety pin at the handle of the carbon dioxide fire extinguisher, hold the bottom of the bottle with one hand and stand upwind of the fire source with the handle with the other.

3. Aim the nozzle at the root of the ignition source and press the handle.

Precautions for using fire extinguishers:

1. The fire extinguisher mainly relies on carbon dioxide to isolate the burning material from the surrounding air, so as to cause the burning material to be extinguished by lack of oxygen and extinguish the fire, so it is not suitable for use in outdoor wind.

2. When used in a small closed room, the user and all personnel must quickly leave after use. For example, when extinguishing oil fires, the spray cartridge should not be too close to the oil surface, so as not to blow the oil away and the fire expand.

3. If the fire of electrical appliances above 600V is extinguished, the power supply should be cut off first. Don't rely too much on carbon dioxide fire extinguishers, if the fire is large, or if the fire has a tendency to spread, be sure to evacuate first, call the fire department**, and ask the fire personnel to extinguish the fire.

4. The principle of carbon dioxide fire extinguisher is to let the fire automatically extinguish after contact with carbon dioxide, so the carbon dioxide fire extinguisher will not hurt the object when it is used, and it is the best way to extinguish the fire for books and office supplies.

Which of the above early capacity rises refers to the encyclopedia - carbon dioxide fire extinguisher.

The following points should be paid attention to when using CO2 fire extinguishers:

Confirm that the fire source has been extinguished: When using a CO2 fire extinguisher, first confirm that the fire source has been extinguished, otherwise it may cause a second **.

Confirm that the surrounding people have been evacuated: CO2 fire extinguishers will release a large amount of carbon dioxide, which will reduce the concentration of oxygen in the surrounding air, which may cause harm to the human body, so make sure that the surrounding people have been evacuated when using socks.

Confirm the correct use: CO2 fire extinguishers are only suitable for Class A, B, and C fires, not for Class D fires, so confirm the type of fire source when using them to ensure that they are used correctly.

Pay attention to the use time of the fire extinguisher: the fire extinguishing time of the CO2 fire extinguisher is short, generally only 10 30 seconds, because it is rented early, it is necessary to pay attention to the time when using it to ensure sufficient fire extinguishing time.

Pay attention to the distance of fire extinguisher: The effective distance of CO2 fire extinguisher is short, generally between 1 3 meters, so pay attention to the distance when using it to ensure that it is close enough.

Pay attention to the safe use of CO2 fire extinguishers: CO2 fire extinguishers will produce extremely low temperatures when used, which may cause damage to **, so pay attention to safe use and avoid direct contact with fire extinguishers.

I'm glad to answer for you, you should pay attention to injuries when using carbon dioxide fire extinguishers:1High-pressure gas:

The pressure inside the CO2 fire extinguisher is very high, and when released, it will produce a strong impact force that can cause objects to collapse, shatter or injure people, so make sure there are no people around when using it and avoid aiming the fire extinguisher directly at the person. 2.Low Temperature:

Carbon dioxide is a refrigerant that rapidly lowers the temperature of the surrounding area when released, and exposure to too high concentrations of carbon dioxide can cause frostbite, so stay away from the spray area when using it and avoid prolonged exposure to carbon dioxide spray. 3.Risk of hypoxia:

CO2 fire extinguishers can consume oxygen in the air, resulting in a decrease in the amount of oxygen in the air, and when using CO2 fire extinguishers in confined or small spaces, resulting in hypoxia and suffocation, it is essential to ensure proper ventilation conditions. <>
