The requirement to preflight the fixed halon fire extinguisher in the lavatory on the CRJ 200 is that the gauge must be in the green zone and the prongs must not be charred or black. This indicates that the extinguisher is in operational condition and ready for use in case of a fire.

The gauge being in the green zone signals that the pressure within the extinguisher is adequate and within the normal operating range, which is critical for its effective functioning. Additionally, the absence of charred or black prongs indicates that the extinguisher has not been previously discharged or damaged, ensuring that it remains fully effective and reliable during an emergency.

It’s important to adhere to these safety checks to maintain passenger safety and comply with aviation regulations regarding emergency equipment. Proper maintenance and preflight checks of safety equipment like fire extinguishers are crucial in ensuring that they are available and usable if needed.
