In the laptop-fire sequence, which action comes after using Halon?

• A. Use H2O
• B. Let it cool
• C. Grab PBE
• D. Move passengers

Answer: (A)

When dealing with a laptop fire, the first step using Halon suppresses the flames, but heat remains in the device, especially in the battery. The next move is to actively remove that heat to prevent reignition. Applying water provides rapid cooling, absorbing heat from the laptop and its battery so the fire cannot flare up again. Letting it simply cool without active cooling is less effective in this high-heat situation, and actions like grabbing a PBE or moving passengers are important but come after the immediate hazard of the device is being controlled. So the action that follows Halon is to use water to cool the device.
