Can the fire extinguisher be used when the pressure gauge pointer is in the yellow zone?

[VonCollin]

The fire extinguisher cannot be used when the pressure gauge pointer is in the yellow zone. More information about the fire extinguisher pressure gauge is as follows: 1. When the fire extinguisher pressure gauge pointer points to the green zone, it indicates that it can be used safely. 2. When the fire extinguisher pressure gauge pointer points to the red zone, it indicates that the pressure inside the bottle is insufficient and cannot be used normally, requiring replacement. 3. When the fire extinguisher pressure gauge pointer points to the yellow zone, it indicates excessive pressure, which can easily lead to danger and should be sent to a specialized institution for inspection and repair. 4. The fire extinguisher pressure gauge is an important indicator to determine whether the fire extinguisher can be used normally, so it should be observed frequently and inspected and repaired regularly.
