The fire extinguishers are valid as follows:
The duration of the co2 extinguisher is 12 years
2. Dry powder extinguishers are valid for 10 years

3. Water-based fire extinguishers are valid for six years。
Use of fire extinguishers:
1. A fire extinguisher pressure gauge. Prior to the use of fire extinguishers, pressure sheets for fire extinguishers need to be checked to see where their pointers are located, indicating that they can be used normally if they are in a green area. And if we do not use it anywhere else, we are vulnerable. If there is any damage to the fire extinguisher or if the fire extinguisher falls, then it is also unserviceable and there are greater security risks

2. Shake the fire extinguishers. Fire extinguishers were not used for long periods of time and the internal powder was deposited together, and direct spraying could not meet the fire-fighting requirements. This needs to be smoothed in order to ensure that the spray is even and that the fire extinguisher works better
3. When safety is removed for sale when the fire extinguisher is shaken, the fire extinguisher will need to be stabilized by hand and the safety of the fire extinguisher will be removed, which will allow for normal fire suppression
4. Aim at the root of the source of the fire. After the safe disposal of the fire extinguisher has been removed, the nozzle of the fire extinguisher is directed at the root of the source. The purpose of this is to allow fire extinguishers to cover the source of the fire directly and thus to isolate the source from air contact for fire suppression purposes

5. Commence fire suppression. When everything is ready, the fire extinguisher switch is pressed and the fire extinguisher is put to the root of the fire, and the fire is extinguished. When used, fire extinguishers need to be supplemented with fire extinguishers in a timely manner, regardless of the dose used, in order to ensure that they continue to be used in the next fire and avoid unnecessary trouble。
In summary, different types of fire extinguishers have different durations. For example, dry powder extinguishers are valid for 10 years, carbon dioxide extinguishers for 12 years and water-based extinguishers for 6 years. In addition, dry powder extinguishers and carbon dioxide extinguishers are released from the plant for a period of five years, after initial repairs for a period of two years, and water-based extinguishers for a period of three years, after initial repairs for a period of one year。
According to the law, fire extinguishers are valid for 12 years (co2 extinguishers), 10 years (dry powder extinguishers) and 6 years (water-based extinguishers), respectively. In the use of fire extinguishers, attention is paid to checking pressure gauges, shaking fire extinguishers, removing safe sales, pointing to the root of the fire and finally pressing the switch for fire suppression。
