2 Green area: the fire extinguisher pressure is normal

3 Yellow area: the fire extinguisher pressure is too high

Three, fire extinguisher maintenance measures

1. The fire extinguisher should be placed in a dry place without corrosive gas.

2. The internal pressure of the fire extinguisher should be checked frequently. If the pointer of the pressure gauge is below the green line area, it should be sent to the maintenance department for repair.

3. After the fire extinguisher is turned on, it must be refilled. Maintenance and filling should be carried out by professional departments, and should be handled carefully during transportation to avoid impact.

4. The fire extinguisher should be maintained by a professional department, and a water pressure test should be carried out before adding water.

5. Aerosol fire extinguishers do not require any maintenance, can be stored without pressure, and are portable and compact.
