When should the fire extinguisher used in fire engineering construction be scrapped?

Fire extinguishers are very useful for extinguishing small fires, but long-term storage has made some fire extinguishers unusable. Then, how can we know whether these fire extinguishers should be scrapped?

    The following points can allow you to make a simple judgment:

    1. The appearance and threaded parts of fire extinguishers and gas cylinders are severely corroded, which affects the strength and safety (the paint on the outer surface of the cylinder body falls off in a large area, and the rust area exceeds one third of the outer surface area of the cylinder body);

    2. The cylinder is seriously deformed due to improper use (such as severe bumps);

    3. There is leakage after the hydraulic test (repair welding is not allowed);

    4. The deformation rate of the cylinder after the hydraulic test exceeds 6%;

    5. The internal machine head does not have (or cannot be installed) the air discharging screw and the fixing screw;

    6. The structure is unreasonable (such as a dry powder fire extinguisher with a flat-bottomed cylinder, an external gas storage bottle and an intake pipe that enters the inside of the cylinder from the cylinder);

    7. The Ministry of Public Security or the provincial fire department has explicitly banned sales, maintenance and use;

    8. Produced by a manufacturer without a production license, and without the name of the manufacturer and the year and month of the factory.

    Discarded fire extinguishers should be stamped with scrap steel stamp or recycled as scrap.
