Can the fire extinguisher be used when the pressure gauge pointer is in the yellow zone?
2 Answers
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.
When the pressure gauge needle of a fire extinguisher is in the yellow zone, it should not be used because excessive pressure may cause the extinguisher to become unstable, leading to uncontrolled discharge of the extinguishing agent or even an explosion, which is extremely dangerous in any situation. In vehicles, the onboard fire extinguisher should be checked regularly. If the needle is found to have moved into the yellow zone, stop using it immediately and move it to a safe place. I take a quick look at the pressure gauge every few months during car washing to ensure it remains in the green zone. Pressure can fluctuate easily with significant temperature changes, so extra attention is needed after parking in the sun during summer. If the needle behaves abnormally, seek professional repair services immediately—do not attempt to fix it yourself to prevent accidents. Remember, a fire extinguisher is a life-saving tool, and poor maintenance can cause it to fail in critical moments. Developing a habit of regular checks can prevent many problems.
