How to manage and maintain fire extinguishers:
(1) The fire extinguisher shall avoid backwards, rain, sun exposure, strong radiation and contact with corrosive substances during transportation and storage.
(b) The temperature of the fire extinguisher storage environment should be in the range of -10-45°C.
(3) Where the fire extinguisher is placed, it shall be kept dry and ventilated to prevent corrosion of the cylinder. Sun exposure and strong radiant heat should be avoided so as not to affect the normal use of fire extinguishers.
(D) Fire extinguishers shall be subject to regular inspections in accordance with the manufacturer's requirements and inspection periods. Fire extinguisher inspection content:
1. The outer surface of the extinguisher pressure gauge shall not have defects such as deformation or damage; otherwise, the pressure gauge shall be replaced;
2. Whether the pointer of the pressure gauge is in the green zone (the green zone is the design working pressure value), otherwise the driving gas should be filled;
3, whether the fire extinguisher nozzle deformation, cracking, damage and other defects, otherwise it should be replaced;
4. The metal parts of the pressure extinguisher, valve body, etc. of the fire extinguisher shall not have serious defects such as damage, deformation, corrosion, etc., otherwise they must be replaced;
5. Severe deformation of the cylinder, serious corrosion of the cylinder (a large area of ​​paint peeling, corrosion area is greater than or equal to one-third of the total area of ​​the cylinder) or the connection site, the bottom of the cylinder must be scrapped;
6. The rubber and plastic parts of the fire extinguisher must not be deformed, discolored, aged or broken, otherwise they must be replaced;
7, portable carbon dioxide fire extinguisher, must use pressure handle valve;
8. Fire extinguishers with a fire extinguishing dose greater than or equal to 4 kg should be replaced with a spray mechanism with a gap or an additional spray gun. Unable to replace should be scrapped;
9. Unreasonable institutions (such as flat-bottomed cylinders, external cylinders, and dry powder fire extinguishers that enter the interior of the barrel from the barrel) must be scrapped; 10. Simple fire extinguishers must not be refilled and maintained. A simple fire extinguisher is a non-refillable, stored-pressure fire extinguisher that is less than 1 kg filled and opened by one finger.
11. In the same batch of fire extinguishers, a fire extinguisher is selected for fire extinguishing performance testing. The ABC (Ammonium Phosphate Salt) dry powder is usually light yellow, and the sprayed powder is fine and free from impurities, and the sprayed powder is heated sufficiently to leave less residue.
(5) Once the fire extinguisher is opened, even if it is not sprayed in large quantities, it must be refilled in accordance with the requirements. Refilling should be performed by a professional maintenance department in accordance with the requirements and methods specified by the manufacturer, and the type and weight of the fire extinguishing agent must not be changed casually. Drive gas pressure.
(6) If a fire extinguisher finds a problem through a functional inspection, it must entrust a maintenance organization with maintenance qualifications to carry out the repair, replace the damaged part, the cylinder for hydrostatic testing, and refill the extinguishing agent and driving gas. Maintenance organizations must strictly implement the fire extinguisher scrapping system. Before the fire extinguisher is refilled every five years and before each time, the main pressure parts, such as the head and cylinder body, shall be subjected to a hydrostatic test, and the qualified person may continue to use it. After the test, it should be dried in time, and check the inner wall. There should be no obvious corrosion. The hydraulic pressure test is unqualified, and welding and other methods are not allowed to be used for repair.
(7) The fire extinguishers repaired by the maintenance department shall be marked with the approval of the fire supervision authority, and be noted with the name of the maintenance organization and the maintenance date. (h) Fire extinguishers, whether used or unused, shall be sent from the date of manufacture (the date of manufacture of each fire extinguisher cylinder) from the date of manufacture to the maintenance organization after the specified maintenance period has expired. Must be scrapped. The fire extinguisher failed to pass the hydrostatic test during maintenance must also be scrapped.
(9) The management office must strengthen the daily management and maintenance of fire extinguishers. It is necessary to establish the “Fire Extinguisher Accountâ€, the type of registration, the number of configuration, the location of the installation, and the person responsible for maintenance and management; and clearly define the duties of the maintenance manager.
(10) The management office shall check the maintenance of the fire extinguisher at least once every quarter. The inspection shall include: the implementation of the maintenance responsibilities of the responsible person, whether the pressure value of the fire extinguisher is within the normal pressure range, whether the insurance pin and the seal are in good condition, and the fire extinguisher cannot be diverted. It is used, placed firmly, no buried pressure, fire extinguisher boxes must not be locked, to avoid sunlight exposure and strong radiant heat, whether the fire extinguisher is within the validity period, etc., to check the status of the fire extinguisher is valid as "fire extinguisher inspection records" Li check.
