There are many small restaurants and shops decorated with exquisite comfort, but the fire extinguishers taken out are either rusty or have obvious signs of damage. For these "old, weak and disabled", they should have been laid off and scrapped long ago.
So how can the average user tell if a fire extinguisher should be scrapped?
To this end, the fire department summed up a few points: from the signs, can not identify the manufacturer, the date of production of fire extinguishers must be scrapped. From the appearance of the structure, the external surface of the pressure gauges for fire extinguishers must not have deformation, damage and other defects; The pressure gauge must point to the green zone; The pressure handles of fire extinguishers, valve bodies and other metal parts have serious damage, deformation, corrosion and other defects affecting the use, must be replaced; The cylinder must be scrapped due to serious deformation and corrosion.
The service life of any kind of fire extinguisher is also limited, the use of fire extinguishers beyond the expiry date will not only affect the fire extinguishing effect, but also may cause injury to the user. Therefore, as long as the expiry date is reached or exceeded, even if the fire extinguisher has not been used, it should be scrapped. Among them, water-based extinguishers have a shorter scrapping period of 6 years, dry powder extinguishers have a longer scrapping period of 10 years, and carbon dioxide extinguishers have a maximum scrapping period of 12 years.
