If the danger of fire occurs, fire extinguishers are indispensable fire-fighting tools, but fire extinguishers can not be used for a long time, the annual inspection of fire extinguishers is the industry standard for regulating the maintenance of fire extinguishers, the following describes the basic items and maintenance procedures for the annual inspection of fire extinguishers.
The basic items specified in the annual inspection of fire extinguishers.
According to the “fire extinguisher maintenance and scrapping” in the annual inspection of fire extinguishers requirements: 1, used fire extinguishers need to be sent to the maintenance agency to check the extinguisher, replenish the extinguishing agent and drive gas, need to be sent to the maintenance agency along with the fire extinguisher maintenance permit. After the expiration of the fire extinguisher, whether used or not, need to send to the fire extinguisher maintenance unit for hydrostatic testing and inspection.
2, “mechanical foam, pure water” portable and trolley-type fire extinguishers should be manufactured in date of three years after the expiration of every two years to carry out a hydraulic test.
3, “chemical foam, acid, and alkali” portable and trolley-type fire extinguishers need to be on the delivery date every two years after the hydraulic test.
4, the fire extinguisher appearance of serious corrosion, serious deformation, unreasonable structure, they are produced by manufacturers without a production license, no manufacturer’s name, and production date. Public safety and fire departments are prohibited from selling and repairing and need to be considered as waste.
Annual inspection and maintenance process for fire extinguishers.
Appearance inspection – Pressure relief – Disassembly – Hydrostatic test – Individual maintenance cylinder drying – Assembly – Filler, nitrogen gas tightness test – Factory inspection.
Fire extinguisher inspection and repair and fire extinguisher repair (annual inspection) include.
1, check the fire extinguisher (release the pressure, open the fire extinguisher detection head, valve, siphon, and pressure gauge, check whether the performance is normal, replace damaged parts) when the need to test the fire extinguisher barrel under 2.5 MP pressure whether the deformation and scrap, and whether the fire extinguisher barrel rust corrosion, the fire extinguisher barrel should be a hydrostatic test.
2, dry the fire extinguisher barrel, fill the drive gas with nitrogen pressure, clean and clean the exterior of the fire extinguisher barrel, and label the annual inspection certificate to maintain the fire extinguisher.
Introduced the basic items specified in the annual inspection of fire extinguishers, annual inspection time, and maintenance process, you should know more about this knowledge, fire extinguisher annual inspection standards apply to the maintenance and retirement of portable fire extinguishers and trolley fire extinguishers, applicable to the assessment of the maintenance conditions and maintenance capabilities of fire extinguisher maintenance agencies.
