What does a green gauge indicate during Halon extinguisher preflight?

• A. Proper pressure in green area
• B. Overpressure in red area
• C. Pressure within yellow range
• D. Pressure indicator unavailable

Answer: (A)

The gauge uses color bands to show whether the extinguisher is properly charged. The green area indicates the pressure is within the proper operating range, so the Halon extinguisher is charged and ready for use. Red would signal out-of-range pressure (over or under), and yellow is a warning that the pressure isn’t in the acceptable range. If the indicator isn’t readable, you can’t confirm readiness and the unit would need service.
