What action should be taken if a fire extinguisher's pressure gauge shows green?

When a fire extinguisher's pressure gauge indicates green, it signifies that the extinguisher is fully charged and in working condition. This green zone on the gauge marks the ideal pressure range, which assures the user that the extinguisher is ready for use in the event of a fire.

A properly maintained extinguisher in the green zone is essential for ensuring safety, as it indicates that the extinguisher has not been discharged or lost pressure due to leaks or other issues. Regular checks of the pressure gauge should be part of routine maintenance to ensure that the extinguisher remains functional and available when needed.

If the gauge were to show anything outside of this green range, actions would then differ—ranging from charging the extinguisher if the pressure is low, to reporting for service or disposal if it is indicated as over-pressurized or non-functional.
