Who is responsible for preflighting the fixed halon fire extinguisher in the lavatory on the CRJ 200?

The responsibility for preflighting the fixed halon fire extinguisher in the lavatory on the CRJ 200 lies with the flight attendant. This role involves ensuring that safety equipment is operational and readily accessible in the event of an emergency, particularly in high-risk areas such as the lavatory where fire hazards may occur.

The flight attendant is specifically trained to check emergency equipment as part of their preflight duties. This includes verifying the presence and functionality of fire extinguishing devices. In the case of the CRJ 200, this responsibility is crucial for maintaining passenger safety and adhering to safety regulations. By ensuring that the halon extinguisher is properly checked, the flight attendant helps to mitigate potential fire risks, thereby contributing to the overall safety of the flight.

The other choices, while important in their own right, do not assume this specific responsibility. The pilot focuses on flying and controlling the aircraft, the ground crew typically handles preflight checks related to aircraft maintenance and systems outside the cabin, and the cabin manager oversees the general safety and service aspects on board but does not conduct equipment checks like the halon extinguisher in the lavatory.
