How can wind influence the placement of a handline?

• A. Wind has no effect on line placement.
• B. Wind can push flames and embers; place line to intercept the forward fire and account for wind shifts.
• C. Only consider wind after finishing line.
• D. Ignore wind and place line wherever shortest.

Answer: (B)

Wind shapes how a fire moves by pushing flames, carrying burning embers ahead, and shifting the direction of spread as terrain and fuel change. When you’re placing a handline, the goal is to intersect the edge of the forward fire and lay the line where the wind is likely to drive the fire next. That means choosing a location that can hold the advancing edge under current wind and any shifts in strength or direction, using terrain and natural barriers to help contain it. If you ignore wind or wait to consider it, the fire can outrun or cross the line; if you just seek the shortest line without accounting for wind, embers and the flame front can jump ahead and render the line ineffective.
