How should line width be determined for brush management?

• A. Always fixed width everywhere.
• B. Always as narrow as possible.
• C. Twice the typical line length.
• D. It should be wide enough to interrupt fuel continuity and provide safe working width, tailored to fuels and terrain.

Answer: (D)

Line width is determined by the need to break fuel continuity and provide a safe working space, with the width adjusted to the specific fuels and terrain you’re dealing with. The goal is to create a real barrier to fire spread, not a fixed stripe, so the line must be wide enough to interrupt continuous fuels like dense brush or thick vegetation and to give crews room to work safely, back out, and mop up if needed. Because fuels can range from light grasses to heavy brush and terrain can be flat, rocky, or steep, the appropriate width changes with conditions. In light, flat ground a narrower line might suffice, but in heavy fuels or challenging terrain you’ll need a wider line to effectively stop the fire and maintain safe access and retreat routes. Fixed or overly narrow line widths can allow fire to bridge the line or put crews at risk, so the best practice is to tailor the width to the fuels and terrain present.
