What color indicates that the gauge is in the proper range for the fixed FE-36 fire extinguisher?

The color that indicates the gauge is in the proper range for the fixed FE-36 fire extinguisher is green. Gauges are often used to communicate the status of various systems, including fire protection equipment. In the case of fire extinguishers, a green indicator typically signals that the unit is charged and ready for operation. It provides a visual reassurance that the equipment is functional and can be relied upon in an emergency.

This color-coding system is essential because it allows personnel to quickly assess the readiness of fire suppression equipment without needing detailed knowledge about its operation or functionality. A green gauge helps ensure that users can act swiftly and effectively in situations requiring fire extinguishment, which enhances overall safety protocols.
