What does line control mean in handline construction?

• A. Constructing without any inspection.
• B. Maintaining a continuous, cleaned edge and staying on the planned route without deviations that reintroduce fuels.
• C. Randomly reentering fuels to test the line.
• D. Only following GPS after resetting.

Answer: (B)

Line control means keeping the fireline solid and reliable as you build it by maintaining a continuous, cleaned edge and staying on the planned route without deviations that could reintroduce fuels. A clean edge is essential because any remaining fuels right at the edge can smolder or catch embers from the fire, risking the line failing or allowing the fire to cross. Staying on the planned route ensures there aren’t gaps or detours where fuels are left behind, which would undermine the purpose of the line. In short, line control focuses on a continuous, well-cleared line that follows the intended path, preventing re-ignition and keeping the line effective. The other options describe practices that would undermine safety and effectiveness: inspecting is part of good practice, but the absence of inspection isn’t the concept being tested; reentering fuels randomly would create new ignition points; and relying only on GPS after resetting doesn’t capture the idea of maintaining a clean, continuous edge along the planned line.
