What is the final action listed in the laptop-fire handling sequence?

• A. Evacuate the aircraft
• B. Return to service
• C. Notify authorities
• D. Let it cool

Answer: (D)

In this scenario, the sequence focuses on safely wrapping up the handling of a laptop battery fire after the immediate hazard is addressed. The final step is to let the device cool. Cooling is essential because lithium-ion batteries can continue to generate heat or even reignite after flames are out; waiting allows residual heat and reactive gases to dissipate, making the device safe to move, inspect, and handle further. Evacuating the aircraft is an urgent action that would occur if the danger is ongoing, not the last step in a tidy cooling-and-continuation sequence. Notifying authorities or returning to service are important but typically occur at different points in the overall process, not as the final action.
