Firefighter 1C Wildland Practice Exam

Finished lines constructed on a steep slope may require which of the following line construction methods?

1. Scratch line

2. Firing out

3. Hotspotting

4. Berm / trench

The correct answer is: Berm / trench

When finished lines are constructed on a steep slope, using a berm or trench method is particularly effective. This approach involves creating a physical barrier that helps control the spread of fire and provides a foothold for firefighters working on steep terrain. A trench allows for the removal of soil and vegetation, which can reduce the fuel available for the fire. Meanwhile, the berm can serve as a protective barrier that helps to contain any potential fire activity within a designated area. On steep slopes, stability and the ability to manage runoff and erosion are critical. The trench acts to divert water runoff during rain, which is important to maintain the integrity of the fire control line. Additionally, this construction method helps firefighters to minimize the risk of rolling debris or fire spread down the slope. While the other methods mentioned may have their applications, they do not specifically address the challenges associated with constructing fire lines on steep terrains as effectively. For instance, scratch lines are generally temporary and may not provide sufficient containment on steep slopes. Firing out involves intentionally setting fire to consume fuel between the fire and the control line, typically used for specific tactical reasons rather than as a primary line construction method. Hotspotting is focused on identifying and managing areas of the fire that are particularly active or at risk,
