How often to repair dry chemical fire extinguishers

Dry chemical fire extinguishers are inspected once a year.

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.

Dry powder fire extinguisher inspection content: First, remove the gas cylinder every six months and weigh the weight of carbon dioxide in the gas cylinder. The leakage of carbon dioxide cylinders of portable fire extinguishers is 5% or 7g of the rated weight (whichever is less), and when the carbon dioxide leakage of cart fire extinguishers is greater than 10%, it shall be sufficient according to the regulations.

The second is to check whether the operating mechanism is flexible, whether the cylinder is tightly sealed, and whether the fire extinguisher cover is tight. The third is to check whether the dry powder is hygroscopic and agglomerated once a year (dry powder can continue to be used when damp drying), and if there is agglomeration, it should be replaced in time. Fourth, check whether the powder outlet pipe, air inlet pipe, nozzle and spray gun of the fire extinguisher are blocked; Whether the moisture-proof film of the powder outlet pipe and the moisture-proof plug of the nozzle are broken.

If the blockage is found, it should be cleaned up in time, and the moisture-proof film and moisture-proof plug should be replaced in time.

Tested once a year. The fire department has a clear regulation: the shelf life of fire extinguishers is one year, so expired fire extinguishers must be inspected, repaired and maintained every other year. Each community or unit must entrust a maintenance agency to do a comprehensive inspection of the fire extinguisher on time.

It must be delivered to a maintenance unit that has obtained a maintenance license.

Hello dear! Thank you for waiting, the dry powder fire extinguisher 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 should be immediately pressurized 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. Like the dry powder fire extinguisher, in the process of use, it must be checked regularly, so as not to have too low pressure and cannot be used normally, so in the event of a fire, it will directly affect the safety.

1. The dry powder fire extinguisher should be inspected once a month, mainly to check the pressure gauge, and when the pressure gauge pointer is lower than the green line area, it 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.

2. The fire extinguisher should check the pressure gauge regularly, when the pressure gauge pointer is lower than the green line area, it should be immediately filled with pressure and repaired, 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 expose it to the sun and be close to the fire source; It should be properly kept and dismantled is strictly prohibited.

Dry chemical fire extinguisher:

Dry powder fire extinguisher is a kind of fire extinguisher, which can be divided into ordinary dry powder fire extinguisher and ultra-fine dry powder fire extinguisher according to the type of dry powder fire extinguishing agent.

The dry powder 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 crushing and drying additives, which can effectively extinguish the initial disaster.

Dry powder fire extinguishers can extinguish general fires, and can also extinguish fires caused by the combustion of oil, gas, etc. Dry powder fire extinguisher uses carbon dioxide gas or nitrogen gas as the power to spray out the dry powder in the cylinder to extinguish the fire. Dry powder is a dry, easy-to-flow fine solid powder, composed of a base material that can extinguish fires and additives such as moisture-proof agents, flow accelerators, and anti-caking agents.

It is mainly used to extinguish the initial fire of flammable liquids such as petroleum and organic solvents, combustible gases and electrical equipment.

Hello, the appearance inspection of dry powder fire extinguisher should be done once a month, mainly to check the pressure gauge, when the pointer of the pressure gauge is lower than the green line area, it should be timely pressure maintenance; The newly purchased ABC dry powder fire extinguisher tank should be tested for water pressure every 5 years, after the first test, and then every 2 years for water pressure test, the mandatory scrapping period of the tank of the dry powder fire extinguisher is 10 years. Generally, the bottle pressure of the fire extinguisher is valid for 1 and a half to 2 years, and it should be filled or replaced regularly.

In accordance with the requirements of the "Fire Safety Inspection and Management Measures", dry powder fire extinguishers are inspected once every six months, and the inspection contents include: checking the appearance, checking whether the various screw joints and connecting bolts are loose, checking whether the fire extinguishing agent is expired, checking whether there is water inside the fire extinguisher, checking whether the safety liner is cracked, checking whether the safety valve and exhaust valve are normal, checking whether the operating parts are rusted, checking whether the pull ring is working normally, checking whether the indication pointer is correct, and checking whether the emergency pull ring can play a normal role.
