Portable dry chemical fire extinguishers are generally once every five years, and if they are repaired, they are once every two years. Dry chemical fire extinguishers should be visually inspected once a month, mainly to check the pressure gauge, and when the pressure gauge pointer is lower than the green line area, it needs to be immediately pressurized for repair.

Fire extinguisher. After each use, the fire extinguisher must be sent to the maintenance unit that has obtained a maintenance permit for inspection, replace the damaged parts, and refill the fire extinguishing agent and driving gas.

Regardless of whether the fire extinguisher has been used or unused, when the specified period has reached the specified period from the date of manufacture, it must be sent to the maintenance unit for hydrostatic test inspection.

Dry powder fire extinguishers are suitable for fires caused by combustible solids, combustible liquids, combustible gases, electrical appliances, etc.

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.

It is not explicitly stated in the fire regulations, but it is specified in the relevant technical standards. Take the common portable dry powder fire extinguisher as an example, if the pressure pointer has not been used in the green zone within 5 years of leaving the factory, it does not need to be filled; After leaving the factory for 5 years or once used, or the pressure gauge pointer in the red zone or close to the red zone, it must be immediately sent to a special maintenance unit for filling, and once filled, it must be refilled every 2 years; After 10 years after leaving the factory, the fire extinguisher will be scrapped.

Dry chemical fire extinguisher is a type of fire extinguisher. According to the type of dry powder fire extinguishing agent, it is divided into: ordinary dry powder fire extinguisher, ultra-fine dry powder fire extinguisher.

According to the mode of movement, it is divided into three types: hand-held, shouting and piggybacking and cart. The fire extinguisher is equipped with ammonium phosphate and other dry powder fire extinguishing agents, which have easy fluidity and dryness, and are composed of inorganic salts and crushed and dried additives, which can effectively extinguish the initial disaster.

The dry powder fire extinguisher uses carbon dioxide gas or nitrogen gas as the power to spray out the dry powder in the cylinder, which can extinguish general fires, and can also extinguish fires caused by the combustion of oil and gas.

Short answer: To identify whether the dry powder fire extinguisher is qualified, you need to check whether it has a national compulsory certification mark.

Analysis: Dry chemical fire extinguisher is a common fire extinguishing equipment used to extinguish various types of fires. However, there are some substandard dry bending powder fire extinguishers on the market, and the use of these fire extinguishers may cause the fire to not be effectively extinguished, or even cause greater losses.

Therefore, it is very important to distinguish whether the dry chemical fire extinguisher is qualified.

First of all, it is necessary to check whether the dry powder fire extinguisher has the national compulsory certification mark. In China, dry powder fire extinguishers need to pass the national compulsory certification before they can be sold and used in the market. This certification mark is usually a red "CCC" mark, but it may also be other certification marks, such as CE, UL, etc.

If the dry chemical fire extinguisher does not have these signs on it, or the signs are unclear and incomplete, then the fire extinguisher may be a counterfeit product and it is not recommended to buy and use.

Secondly, you need to check the production date and expiration date of the dry chemical fire extinguisher. Dry chemical fire extinguishers usually have a production date and an expiration date, the production date refers to the date of production of the fire extinguisher, and the expiration date refers to the period during which the fire extinguisher can be used normally. If the production date of the dry chemical fire extinguisher has passed a long time, or the expiration date has expired, then this fire extinguisher may have lost its fire extinguishing effect and is not recommended to use.

In addition, it is necessary to look at the appearance and packaging of the dry chemical fire extinguisher. Qualified dry powder fire extinguishers should have a neat appearance, no damage, no rust, no deformation and other phenomena. The packaging should be intact and have no signs of being opened.

If there is a problem with the appearance or packaging of the dry chemical fire extinguisher, then this fire extinguisher may have a quality problem and is not recommended.

Finally, it is necessary to pay attention to the use and precautions of dry chemical fire extinguishers. Even a qualified dry chemical fire extinguisher may not be effective in extinguishing a fire if it is not used correctly or without precautions. Therefore, when purchasing and using dry powder fire extinguishers, you need to carefully read the book to understand the use methods and precautions to ensure that the fire extinguisher can be used correctly.

In short, to identify whether the dry powder fire extinguisher is qualified, it is necessary to check whether it has the national compulsory certification mark, whether the production date and validity period are compliant, whether the appearance and packaging are intact, and whether the use methods and precautions are correct. Only by ensuring the correct quality and use of dry powder fire extinguishers can we effectively extinguish fires and ensure the safety of people and property.

It is necessary to have an inspection once a month, mainly to check the pressure gauge.

When the pointer of the volt gauge is lower than the green line area, it should be repaired immediately. The newly purchased Kaiyuan with ABC dry powder fire extinguisher tank should be tested for water pressure once every 5 years, after the first detection of the crack source, the water pressure will be tested every 2 years, and the mandatory scrapping period of the tank is 10 years. <

Portable dry chemical fire extinguishers need to be visually inspected once a month, mainly to check the pressure gauge. When the pressure gauge pointer is lower than the green line area, it should be repaired immediately. The newly purchased ABC dry powder fire extinguisher tank should be tested for water pressure once every 5 years, after the first test, and then every 2 years, the mandatory scrapping period of the tank is 10 years.
