When should the aircraft’s fire extinguishers be used?

The use of aircraft fire extinguishers is appropriate when there is a fire on board that can be safely approached. This is based on standard emergency procedures that prioritize safety and effectiveness in responding to onboard fires.

Using a fire extinguisher entails taking a risk; therefore, it should only be done if the fire is manageable and not spreading rapidly or threatening lives. In such cases, trained personnel can act decisively to contain or eliminate the fire, thereby ensuring the safety of all passengers and crew on board.

In contrast, situations such as detecting smoke in the cabin, sensing a burning odor from a passenger, or limiting use merely to landing scenarios focus on symptoms or specific times, rather than addressing a clear and immediate situation where an extinguisher would be necessary. The use of the extinguisher should be based on the assessment of the fire's accessibility and the safety of the area, rather than on circumstantial symptoms or inappropriate timing.
