How are fire extinguishers maintained? What to do with a fire extinguisher after use?

The user unit should check the maintenance of the fire extinguisher at least once a quarter, and the inspection content includes: the implementation of the maintenance responsibilities of the responsible person, whether the pressure value of the fire extinguisher is in the normal pressure range, whether the safety pin and lead seal are intact, the fire extinguisher can not be diverted for other purposes, placed firmly, there is no buried pressure, the fire extinguisher box shall not be locked, to avoid sunlight exposure and strong radiant heat, whether the fire extinguisher is within the validity period, etc., to check the effective status of the fire extinguisher into a "status card", hang on the fire extinguisher cylinder to clearly indicate. The user shall organize or entrust the maintenance unit to conduct a functional inspection of all fire extinguishers at least every 12 months, and the main inspection contents are:

Whether the fire extinguisher cylinder is corroded or deformed; whether the nameplate is complete and clear; Whether the nozzle is deformed, cracked, or damaged; Whether the jet hose is unblocked, deformed and damaged; Whether the outer surface of the fire extinguisher pressure gauge is deformed or damaged, and whether the pointer points to the green zone; Whether there are defects that affect the use of metal parts such as fire extinguisher pressure handles and valve bodies such as serious damage, deformation, and corrosion; Whether the rubber and plastic parts of the fire extinguisher are deformed, discolored, aged or broken; One fire extinguisher from the same batch of fire extinguishers was selected for fire extinguishing performance test. If the fire extinguisher is found to have problems after functional inspection, it must be entrusted to a maintenance unit with maintenance qualifications to repair it, replace the damaged parts, carry out the hydraulic test of the cylinder, and refill the fire extinguishing agent and driving gas.

1. Daily management and maintenance of fire extinguishers: the EHS department is responsible for the supervision of the use and maintenance of fire extinguishers and the maintenance and replacement of fire extinguishers; The fire extinguisher is managed by a special person, in principle, "who uses and maintains", and the department (administration, storage and incineration) of the fire extinguishing area covered by the fire extinguisher is arranged to manage the personnel, and it is required to keep it clean daily and inspect it once a week, and fill in the inspection record form and sign at the same time; No debris shall be piled up around the fire extinguisher; The storage environment should be ventilated and dry, avoid sun and rain, and the temperature should be -20 +55; It is strictly forbidden to use fire extinguishers to play and play, and it is strictly forbidden for non-professionals to disassemble fire extinguishers; The fire extinguisher should not be inverted or horizontally during transportation and storage, and should be handled with care when loading and unloading, and beware of bumping; Keep access to fire extinguishers clear and fire extinguishers must not be blocked; The fire extinguisher cannot be used for other purposes without permission.

2. Key points of daily inspection of fire extinguisher: check whether the pointer of the pressure gauge of the fire extinguisher is in the working area (that is, within the green range); Check whether the connections, mainly the connection between the valve and the bottle, the connection between the pressure gauge and the valve, the connection between the nozzle and the nozzle and the valve, are firm and reliable; Whether the fire extinguisher cylinder is rusted or deformed, and whether the nameplate is complete and clear; whether the nozzle of the fire extinguisher is deformed or blocked; Whether the spray gun and hose of the cart fire extinguisher are blocked, whether the hose is damaged or cracked, and whether the wheels are flexible.

1. Daily inspection: check whether the pressure is within the specified range; Check whether the safety pin is corroded, whether the rotation is flexible, and whether the lead seal is intact; Whether the metal parts such as the fire extinguisher's pressure handle, valve body, and thimble are seriously damaged, deformed, and corroded; Check whether the powder spraying pipe has aging and cobwebs; Check whether the cylinder is deformed, whether there is rust at the bottom, and whether there are cobwebs; Check whether the dry powder is agglomerate; Check that the fire extinguisher is within its expiration date. (4kg dry powder fire extinguisher for 10 years; 35kg dry powder fire extinguisher for 12 years; carbon dioxide fire extinguisher for 12 years); Whether the rotating parts on the frame of the cart-type fire extinguisher are loose, and whether they are flexible and reliable when rotating; Check whether the items marked on the nameplate are clear and complete.

2.Daily maintenance: frequently clean and tidy the surface, powder spraying pipe and safety pin; Lubricate and maintain the active parts regularly; Regularly shake the cylinder appropriately to prevent the dry powder from agglomerating; When the pressure is lower than the specified range or the dry powder is seriously agglomerate, it should be repaired or replaced; Dry powder and carbon dioxide fire extinguishers must be tested for water pressure after five years of factory filling with fire extinguishing agent, and then every two years.

When the scrapping life is reached, it should be replaced in time.

3. Fire extinguisher operation method:

Before use, turn it upside down several times, stand upwind at the outlet, keep a distance of 5m from the combustible, remove the lead seal, pull out the safety pin, hold the powder spray hose, aim at the root of the flame, press the pressure handle, and start to strafe left and right.

Operation method of cart-type dry powder fire extinguisher: two people operate, stand upwind, and keep a distance of 10m from the combustible. One person removes the spray gun, hose, and aims it at the root of the flame; The other person pulled out the safety pin and quickly turned on the opening mechanism of the fire extinguisher.

The operation method of the carbon dioxide fire extinguisher: first pull out the safety pin, then open the pressure handle with one hand, hold the handle of the horn spray canister with the other hand, and hold the open pressure handle tightly to spray out.

After the fire extinguisher is used, first of all, remember to place it upside down, and if it continues to be used, send it to a professional place for replenishment or pressurization. If you don't want it, you may send it for processing. Generally, the place where fire-fighting equipment is sold will do.

After each use, the fire extinguisher must be sent to a repair unit that has obtained a repair permit (hereinafter referred to as the repair unit) for inspection, replacement of damaged parts, and a new filling of fire extinguishing agent and driving gas.

Fire extinguishers, after the end of the handover, or to the formal ** organization to deal with, do not deal with it privately, if you want to change the powder, but also to a professional organization to replace.

Fire extinguisher is the most important existence in daily life, which can extinguish the fire source as soon as possible in the event of a fire accident, so as to ensure personal safety, but it is also necessary to have a certain understanding of fire extinguishers. So how do you keep the fire extinguisher?

1. In the process of storing the fire extinguisher, try to avoid the surrounding environment being too humid, otherwise it is likely to lead to corrosion on the surface of the fire extinguisher, so that it cannot withstand the pressure of the internal fire extinguishing agent, and finally appears. And the fire extinguisher should not be stored in a high-temperature environment as much as possible, otherwise there will be expansion, which will also lead to **.

3. The area where the fire extinguisher is placed should not be in a position where it is often walked, otherwise it is very easy to receive impact, resulting in the deformation of the fire extinguisher. In addition, if the extinguisher is expired, do not throw it into the garbage heap, otherwise it will cause unnecessary trouble due to the inert gas present inside the fire extinguisher.

3. The fire extinguisher has been stored for a long time, and it is necessary to do a good job of testing, and replace the rough skin fire extinguishing agent inside the fire extinguisher in time to ensure the safe use of the rock in the later stage. Moreover, if the fire extinguisher cannot spray the fire extinguishing agent, you can use the wire to dredge, try not to throw it into the fire, which is easy to produce violent**.
