Which statement about downhill fireline construction is false?

• A. It is more favorable to construct downhill fire indirect.
• B. It is not more favorable to construct downhill fire indirect.
• C. Downhill construction is never used.
• D. Downhill construction should always be avoided.

Answer: (A)

Downhill fireline construction tends to be riskier and harder to defend than building on other parts of the slope. On a downhill slope, debris and embers can roll or be blown downhill toward the line, and the crews working below the fire are often in a more exposed position with limited ability to retreat upslope if conditions shift. Because indirect line work already requires placing a line at a distance from the fire and extending control with favorable anchor points, doing it downhill usually increases hazards and complicates control, not makes it more favorable. So saying that it is more favorable to construct downhill indirect lines is not correct. In practice, engineers and firefighters weigh slope, wind, and fuel; downhill locations are considered only when necessary and with extra safety measures, rather than being inherently more favorable.
