At what position on the pressure gauge is the fire extinguisher's pressure considered normal?

1 Answers

The normal pressure value is indicated by the green zone on the gauge, with pressure approximately between 1.2—1.5 MPa. Here are the relevant explanations: 1. When the pointer is in the red zone: This indicates insufficient pressure inside the cylinder, rendering the fire extinguisher unusable and requiring replacement. 2. When the pointer is in the yellow zone: This signifies excessive pressure, posing a potential hazard, and the extinguisher should be sent to a specialized facility for inspection and repair. 3. Once a fire extinguisher has been activated: Even if only a small amount has been discharged, it must be refilled according to specified requirements. Refilling should be performed by professional maintenance departments following the manufacturer's prescribed methods and requirements. Alterations to the type of extinguishing agent, weight, or driving gas pressure are not permitted.
