What is a dozer line and when is it typically used?

• A. A line cleared by hand tools; used in rough terrain
• B. A fireline constructed with bulldozers to remove fuels; used when terrain or fuel conditions require heavy, continuous barriers
• C. A line painted on the ground to mark boundaries
• D. A line created using water channels only

Answer: (B)

A dozer line is a fireline created with bulldozers that removes fuels down to mineral soil to form a continuous, durable barrier. It's used when terrain or fuel conditions require a heavy, uninterrupted barrier that can be established quickly and withstand erosion and movement, such as steep or rough terrain, dense brush or timber, or long lines where manual digging would be too slow or unsafe. Other methods like hand-cleared lines or painted markings don’t provide the same heavy, continuous separation or durability that a dozer line offers.
