Which action best helps manage vapors during an aircraft fire?

• A. Directing foam downwind
• B. Positioning foam curtains upwind and aligning apparatus to minimize exposure
• C. Ignoring wind direction
• D. Using only water streams

Answer: (B)

Managing vapors during an aircraft fire relies on using the wind to your advantage and creating a vapor-suppressing barrier between the fuel and the crew. Positioning foam curtains upwind places the foam blanket in the path of the vapor as it would otherwise travel with the wind, helping to block and cool the spreading vapors before they reach personnel or exposures. Aligning the apparatus to minimize exposure ensures you’re keeping responders shielded by the foam barrier and staying out of the vapors’ direct path. Foam not only blankets the surface but also reduces vapor release, which water streams alone cannot do effectively. Directing foam downwind would push vapors toward you, and ignoring wind direction or relying solely on water would fail to control vapor spread and protection.
