Can the post office issue dry powder fire extinguishers, and where can dry powder fire extinguishers

It seems that you don't have to find a professional logistics consignment, in addition, why do you want to mail a dry powder fire extinguisher 5 kilograms is only more than 100 yuan, how much do you have to pay for the mailing, Jingyang Fire Check the relevant requirements for fire extinguisher transportation.

First, the fire extinguisher should be filled with dry powder.

After the fire extinguisher has no dry powder, we can go to the place where the fire extinguisher was purchased at that time to fill the dry powder, or we can go to the fire equipment store to fill the dry powder, if we don't know that the fire equipment store is in the **, we can go to the local fire brigade near the look, there are generally, or you can go directly to the fire brigade for inflation.

2. What are the precautions for using fire extinguishers?

1. When we use the fire extinguisher, we must pay attention to the position above the fire extinguisher. If you are not in the upper hand, it is very likely that a gust of wind will burn on your body as soon as it comes, bringing great danger to yourself.

2. In the process of extinguishing the fire, you must ensure that your surroundings are safe before you can start extinguishing the fire, and when you are not sure that you are in a safe situation, you must not get close to the fire source to prevent the fire source from not extinguishing and causing a fire in your own body.

3. When using the dry powder fire extinguisher, it needs to be filled immediately, if it is not filled, there is no way to use it next time.

4. When using a fire extinguisher, you must see clearly what type of fire extinguisher you use, there are many types of fire extinguishers, and the methods used are also a little different.

Of course. Dry chemical fire extinguishers can extinguish general fires and fires caused by the combustion of oil and gas. It is mainly used to extinguish the initial fire of flammable liquids such as oil and organic solvents, flammable gases and electrical equipment. The dry powder fire extinguisher is equipped with an ammonium phosphate dry powder fire extinguishing agent.

Can dry chemical fire extinguishers be used for electrical fire extinguishing?

Dry powder fire extinguishing agent is a dry, easy-flowing fine powder used to extinguish fires. It is made of inorganic salts and a small amount of additives with fire extinguishing effect by drying, crushing and mixing into fine solid powder.

In addition to the special dry powder chemical fire extinguishing agent for fighting metal fires, dry powder fire extinguishing agent is generally divided into BC dry powder fire extinguishing agent (sodium bicarbonate, etc.). ) and ABC dry powder (ammonium phosphate, etc.). ).

Dry chemical fire extinguishers can be divided into hand-held, backpack and cart types according to the way of movement. When using an external portable fire extinguisher, hold the sprinkler head with one hand and lift the lifting ring with the other hand to spray the dry powder.

It is okay in the case of a small fire, or in the initial state of ignition. The fire is too big, and there is no way to put a fire extinguisher.

First, the substances that are extinguished are not the same.

Dry powder fire extinguisher: 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. Dry chemical fire extinguishers cannot extinguish fires with light metal burning.

Carbon dioxide fire extinguisher: carbon dioxide fire extinguisher is to use the carbon dioxide gas stored in the high-pressure gas cylinder as the fire extinguishing agent to extinguish the fire, 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.

Foam fire extinguisher: Foam can cover the surface of the combustible material and prevent air from entering. It is most suitable for fighting liquid fires, and cannot extinguish fires of water-soluble flammable and flammable liquids (such as alcohols, esters, ethers, ketones and other substances) and electrical fires.

Second, the fibrillation material of the fire extinguisher is different.

Dry powder fire extinguisher: ammonium phosphate and other dry powder fire extinguishing agents.

Carbon dioxide fire extinguishers: Carbon dioxide fire extinguishers are carbon dioxide gas stored in high-pressure gas cylinders.

Foam fire extinguisher: a mixture of sodium bicarbonate and foaming agent, and a glass bottle liner containing an aqueous solution of aluminum sulfate.

Third, the principle of fire extinguishing is different.

Dry powder fire extinguisher: The dry powder fire extinguisher is filled with ammonium phosphate dry powder fire extinguishing agent. Dry powder fire extinguishing agent is a dry and easy-to-flow fine powder used for fire extinguishing, which is composed of inorganic salts with fire extinguishing effect and a small amount of additives that are dried, crushed and mixed into fine solid powder.

Carbon dioxide fire extinguisher: Liquid carbon dioxide is compressed in a small cylinder when pressurized, and then sprayed out when the fire is extinguished, which has the effect of cooling and isolating the air.

Foam fire extinguisher: When using foam fire extinguisher to extinguish fire, a large amount of foam can be sprayed, which can adhere to the combustibles, isolate the combustibles from the air, and at the same time reduce the temperature, destroy the combustion conditions, and achieve the purpose of extinguishing the fire.
