How many years does the dry powder in the dry powder fire extinguisher be replaced?

Portable dry powder fire extinguisher (gas cylinder type) for 8 years, portable storage pressure dry powder fire extinguisher for 10 years, cart dry powder fire extinguisher (gas cylinder type) for 10 years, and cart storage pressure dry powder fire extinguisher for 12 years.

BAI dry powder fire extinguishers should be inspected once a month, mainly to check the pressure gauge, when the pressure gauge pointer is lower than the green line area, DAO should be immediately charged for maintenance; The newly purchased ABC dry powder fire extinguisher tank should be tested once in 5 years, after the first test, and then every 2 years after the water pressure test, the mandatory scrapping period of the tank is 10 years.

The fire extinguisher should be checked regularly for pressure gauge, when the pressure gauge pointer is lower than the green line area, it should be immediately pressurized for maintenance, and the general fire extinguisher bottle pressure is valid for 1 and a half to 2 years, and it should be regularly charged or replaced. The fire extinguisher should be placed in a clean and dry place, and it is strictly forbidden to be exposed to the sun and close to the fire source and high temperature; It should be properly kept and dismantled is strictly prohibited.

According to the "Fire Extinguisher Repair and Scrapping Regulations" (GA95-2007):

After each use, the fire extinguisher must be sent to the maintenance unit that has obtained the maintenance license 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.

Portable and cart-type 1211 fire extinguishers, portable and cart-type dry chemical fire extinguishers, and portable and cart-type carbon dioxide fire extinguishers must be inspected for one year after the expiration of the hydrostatic test.

Portable and trolley-type chemical foam fire extinguishers and portable acid and alkali fire extinguishers must be inspected by hydrostatic tests after the expiration of two years, and every other year thereafter.

With the development of the times, we find that more and more people are aware of the importance of having a fire extinguisher. After all, safety comes first, and if you can't find a water source within the time of the fire, you can only use a fire extinguisher. However, when you buy a fire extinguisher, you don't know much about it.

For example, dry chemical fire extinguishers.

There is no need to change it inside, but it is best to change the filling once a year, and the general dry powder fire extinguisher is calculated from the date of completion of production, and the validity period is 5 years. 3. After that, it needs to be inspected and repaired every two years, and it will be forcibly scrapped and can no longer be used. If possible, be sure to equip a fire extinguisher, but just buying it is far from the end, don't forget that the usual maintenance is not less, to change the powder at the appropriate time, pay attention to the shelf life of the fire extinguisher.

Nowadays, people's awareness of prevention is still relatively high, and fire extinguishers are also very popular. Many people have fire extinguishers in their homes, workshops or cars. Of course, no one wants a fire to happen, and we also need to understand that the fire extinguisher has a certain service life, and the fire extinguisher needs to be replaced for a year?

1. Do you change the powder of the fire extinguisher once a year?

1. The so-called powder is also the fire extinguishing agent, and one is carbon dioxide.

The fire extinguisher needs to be replaced with dry powder. If the fire extinguisher has already been used, it needs to be sent to the designated fire department for replacement in time, and the pressure needs to be tested. If the internal extinguishing agent is missing, it needs to be added in time, so it is not necessary to change the powder once a year.

If you have already used it, you need to replace it or add it in time.

2. If it is not used, for the newly purchased fire extinguisher, it is necessary to replace the dry powder once after two years. After that, you basically need to change it once a year. When replacing it, the main thing is to see if the dry powder has a wet clumping problem, if it has already agglomerate, even if it does not arrive at the time, you need to replace it with a new dry powder.

2. The validity period of dry powder fire extinguishing agent is several years.

1. If you choose a dry powder fire extinguisher at home, its validity period is determined by two aspects, one is the bottle and can of the fire extinguisher. According to national regulations, the mandatory scrapping period is 10 years. On the other hand, the dry powder in it also has an expiration date, generally speaking, 1 2.

2. After replacement, a new expiration date will be affixed from the date of delivery.

3. What problems need to be paid attention to when using dry powder fire extinguishers?

1. If it is a portable dry powder fire extinguisher, you need to pull out the safety pin before, and then there will be dry powder sprayed out, and you also need to shake the dry powder fire extinguisher up and down before use, so that the fire extinguisher inside is loose.

2. When using the fire extinguisher, you must pay attention to it, and you can't use it upside down, otherwise the fire extinguisher will not be sprayed. When extinguishing a fire, it is necessary to align the hose with the flame before opening the valve.

Dry chemical fire extinguishers do not stipulate the replacement period, but stipulate that they need to be repaired once every five years.

Repair period of fire extinguisher:

1. Portable water-based fire extinguisher: maintenance after 3 years of delivery; Repair every 1 year after the first repair.

2. Trolley water-based fire extinguisher: maintenance after 3 years of delivery; Repair every 1 year after the first repair.

3. Portable (pressure storage) dry powder fire extinguisher: maintenance after 5 years of delivery; After the first maintenance, it will be overhauled every 2 years.

4. Portable (gas cylinder type) dry powder fire extinguisher: maintenance after 5 years of factory delivery; After the first maintenance, it will be overhauled every 2 years.

5. Trolley type (pressure storage type) dry powder fire extinguisher: maintenance after 5 years of factory delivery; After the first maintenance, it will be overhauled every 2 years.

6. Trolley type (gas cylinder type) dry powder fire extinguisher: maintenance after 5 years of factory delivery; After the first maintenance, it will be overhauled every 2 years.

Precautions for the use of fire extinguishers:

1. When using the portable dry powder fire extinguisher, it should be noted that the dry powder fire extinguisher should be turned upside down several times to loosen the dry powder in the cylinder before opening the powder spraying.

2. After extinguishing the fire, pay attention to prevent recurrence.

3. Water-type, foam, ammonium phosphate dry powder, and alkyl halide fire extinguishers should be used to extinguish Class A fires.

4. Dry powder, foam, halide alkyl and carbon dioxide fire extinguishers should be used to extinguish Class B fires, and chemical foam fire extinguishers should not be used to extinguish Class B fires with polar solvents.

5. Dry powder, halide alkyl and carbon dioxide fire extinguishers should be used to extinguish Class C fires.

6. Halide, carbon dioxide, and dry powder fire extinguishers should be used to extinguish live fires. Ammonium phosphate dry powder and halide type fire extinguishers should be used to extinguish class A, B, C fires and live fires.

After the new two years, once a year after that, regularly check the pressure gauge every month and fill it immediately if it is below the green zone.

The dry chemical fire extinguisher is normal and should be replaced once a year.

The newly bought fire extinguisher is replaced with dry powder once after 2 years, and then it is generally changed once a year. It is worth noting that the dry powder fire extinguishing agent is valid for four years, which refers to the period of use, but generally speaking, it should be carried out every year, mainly to check whether the dry powder is wet and agglomerate, and some powder wet and agglomerated for less than four years should also be replaced with a new agent.

The maintenance procedures for dry chemical fire extinguishers are as follows.

1.Inspect the vents on the top cover to ensure they are clean and free of occlusion.

2.Measure the weight of the fire extinguisher to find out whether the quantity of fire extinguishing powder in the cylinder is suitable, and the appropriate quantity should be indicated on the cylinder. If the powder loss reaches more than 10%, the powder in the cylinder should be replaced.

Due to the chemical reaction caused by the mixing of different powders, special care should be taken when replacing them.

3.Shake the powder in the cartridge to prevent it from condensing.

4.Open the top lid and check the condition of the powder inside the cartridge to make sure it is in good condition, otherwise it should be replaced.

5.Inspect the nozzle and radiation controller (if fitted) in detail to ensure they are clean and in good condition. Damaged accessories should be replaced.

6.Measure the weight of the trachea, check it with the weight indicated on the tube, and replace the trachea if it is found that the gas loss in it is more than 10%.

7.Inspect the inside and outside of the barrel to ensure that there is no rust or damage, and pay special attention to the hidden areas of the barrel.

8.Before the top cap is attached and the trachea is not screwed on, the top of the cap should be inspected for the impact switch or other operating device to ensure its flexible operation. If the rubber pad inside the cover is damaged, it must be replaced. The top cover must be tightened when attached to prevent air leakage.

9.If there is rust on the barrel body or there is doubt about the condition of the cylinder body, a hydrostatic test should be carried out immediately to ensure that the fire extinguisher is in good condition.

10.Every five years, the hydraulic test of the cylinder body should be carried out according to the factory instructions. Special care should be taken when preparing and conducting hydrostatic tests.

12.Before the hydrostatic test, the top cover must be opened to allow the compressed air hose to be removed and the dry powder** to be recycled or disposed of, and the materials and gases in the cylinder should not be discharged in the form of radiation.

13.Before disposing of the failed fire extinguisher, the top cover should also be opened to allow the compressed air hose to be disassembled and the dry powder** to be recycled or disposed of, and the materials and gases in the cylinder should not be discharged in the form of radiation.

Dry powder fire extinguisher is a kind of fire fighting equipment that we are more common, the new dry powder fire extinguisher generally needs to be replaced once in five years, and the powder will be changed once after two yearsHowever, it is worth noting that the dry powder fire extinguishing agent is valid for four years, which refers to the service period, but generally speaking, it should be inspected every year, mainly to see whether the dry powder of the fire extinguisher has deteriorated, and some powders have wet agglomeration, so the fire extinguisher should be replaced with a new agent if it is used for less than four yearsNot all fire extinguishers will come in handy within the deadline, so some dry chemical fire extinguishers will be left in the corner for a long time in case they are needed.

Newly purchased dry chemical fire extinguishers need to be replaced every 2 years, and then every year. It is also necessary to check regularly, and if it is found that the dry powder is damp and agglomerate, it should be replaced in time. Dry powder fire extinguishing agent has been widely used in fire fighting, relying on the substance in the dry powder, and the free radicals generated in the combustion to have a chemical inhibition effect, can effectively extinguish the fire.

Dry powder replacement time for dry powder fire extinguisher.

The newly purchased fire extinguisher is replaced with dry powder every 2 years, and then once a year after that. The validity period of dry powder fire extinguishing agent is 4 years, but it is generally necessary to inspect it every year, mainly to check whether the dry powder is damp, and if it is found that the balance of damp agglomeration should be replaced in time.

Dry powder fire extinguishing agent is a dry and easy-to-flow fine powder used for fire extinguishing, with inorganic salts with killing effect and a small amount of dry powder fire extinguisher additives, and is composed of fine solid powder formed by drying, crushing and mixing, which is a fire extinguishing agent that has been widely used in fire fighting.

The dry powder fire extinguishing agent relies on the volatile decomposition of inorganic salts in the dry powder and the free radicals generated during the combustion process to chemically inhibit the combustion chain reaction and extinguish the fire. When the powder of the dry powder falls outside the surface of the combustible, a chemical reaction will occur, which can isolate oxygen and extinguish the fire.

Dry chemical fire extinguishersIt's not a yearAs long as it is within the expiration date.

There is no need to change the inside. Generally, dry chemical fire extinguishers are valid for 5 years from the date of manufacture. After that, it will be tested every two years and scrapped for ten years.

The dry powder fire extinguisher is equipped with ammonium phosphate and other dry powder fire extinguishing agents, which have easy fluidity, dry and inorganic salts.

and crushed and dried additives, which can effectively fight the first disaster.

How to maintain a fire extinguisher on a daily basis:1. Frequently clean and sort out the surface, powder spraying pipe and safety pin.

2. Lubricate and maintain the active parts regularly.

3. Regularly shake the cylinder appropriately to prevent dry powder from agglomerating.

4. When the pressure is lower than the specified range or the dry powder is seriously agglomerate, it should be repaired or replaced.

Legal Analysis] The validity period of dry chemical fire extinguishers has two aspects. 1.One is the fire extinguisher cylinder, according to the relevant national regulations, the mandatory scrapping life of the dry powder fire extinguisher is 10 years, that is, the validity period of the dry powder fire extinguisher cylinder is 10 years.

2.On the other hand, the fire extinguishing agent of the dry powder fire extinguisher also has an expiration date, according to the relevant regulations of the national building fire extinguishing: stored at normal ambient temperature, the validity period of the dry powder fire extinguishing agent is 5 years.

But generally speaking, the replacement period of dry powder fire extinguishing agent is 1 to 2 years, and when the fire extinguisher is refilled, the maintenance unit will be labeled with the annual inspection label of the fire extinguisher, that is to say, in most cases, the dry powder fire extinguisher is within 10 years of validity period, and it needs to be refilled with dry powder fire extinguishing agent every 1-2 years, and this kind of validity period refers to the fire extinguisher calculated from the date of delivery.
