As a relatively common fire fighting equipment, enterprises, units and families will buy fire extinguishers, but do not think that buying a fire extinguisher is all right. If the fire extinguisher is not repaired and functional inspection is not carried out in time, it will be used in an emergency when the fire extinguisher is needed, resulting in the expansion of the fire, or even the inability to use, resulting in the expansion of the fire and casualties. Therefore, the maintenance of fire extinguishers is very important. How often do you need to maintain them?
1. Period of validity of fire extinguisher barrel.
There are two aspects of the validity of fire extinguishers. One is the fire extinguisher barrel. The state stipulates the mandatory retirement period of fire extinguishers; In addition, on the one hand, the fire extinguishing agent in the fire extinguisher also has its own period of validity, that is, the maintenance period.
2. Scrap life of fire extinguisher.
From the date of delivery, fire extinguishers with the following service life must be scrapped.

3. Service life of fire extinguisher.
Generally speaking, the maintenance period is different according to the type of fire extinguisher. According to the standards of Shandong Province,
It shall be sent to a unit with maintenance qualification above Level 3 for maintenance (refer to local specifications for other regions).
Note: Some friends will have questions, saying that there are still many chemicals left in the fire extinguisher after the fire is extinguished. Can we not refill the chemicals and continue to use it next time? The clear answer has been given in Clause 7.1.2a. It is impossible! It needs to be sent to the manufacturer for repair!
Relevant regulations: according to the provisions of the Fire Extinguisher Maintenance (GA95-2015), the maintenance certificate shall be affixed to the bottle body of the fire extinguisher for maintenance, and the certificate shall include:
1. Maintenance number;
