9, cart-type dry powder fire extinguisher (gas cylinder type) 10 years;
10, cart storage pressure dry powder fire extinguisher for 12 years;
11, cart type 1211 fire extinguisher for 10 years;
12, cart carbon dioxide fire extinguisher for 12 years.
Retired signs: Fire extinguishers or gas cylinders that should be scrapped must be perforated in the barrel or bottle body, and marked with 'sticky' stickers, as follows:
a. 'Retired', the minimum font size is 25mm x 25mm;
b. Retired years and months;
c. name of the maintenance organization;
d. Inspector's signature.
The shelf life does not mean that it can be used before. One year's inspection is necessary, and the fire extinguisher must be refilled after it has been opened. Pressure can be used in green and yellow. There is no pressure in red, and there is no use of fire. Try to ensure one year inspection and check it from time to time to ensure that the fire will work.
Second, how to handle the fire extinguisher after its expiration?
There are many kinds of fire extinguishers, and each fire extinguisher has different validity and maintenance methods. The maintenance of fire extinguishers shall be carried out by a special unit in accordance with the requirements specified by the manufacturer. Before the portable dry powder fire extinguisher is refilled every five years or before, hydraulic pressure tests shall be carried out on the heads, cylinders, and gas cylinders, and the airtightness test shall be conducted on the refilled gas cylinders. The hydrostatic test and hermeticity shall be performed. Only after passing the test, can it continue to be used; dry powder storage tanks and carbon dioxide cylinders for cart-type dry powder fire extinguishers are required to be subjected to hydrostatic tests every three years, and they can only be used after passing the standard. Each time the air mechanical foam extinguisher is changed, the extinguishing agent has been extinguished or has been in the factory for three years. The hydraulic strength test should be carried out and qualified before it can continue to be used; the carbon dioxide fire extinguisher should be subjected to a hydrostatic test every five years or before filling. After being qualified, it can continue to be used; the water fire extinguisher should be subjected to a hydrostatic test before each filling. Can be used for filling, carbon dioxide cylinders should be weighed once every six months, if there is a leak, should be re-inflated. Fire extinguishers are counted from the date of manufacture and reach the following ages and must be scrapped: water-based fire extinguisher - 6 years; dry powder fire extinguisher - 10 years; clean gas fire extinguisher - 10 years; carbon dioxide fire extinguisher and gas cylinder - 12 years; The scrapping of fire extinguishers shall be carried out by special units in accordance with regulations.
