Which type of ladder is carried with the tip forward?

The correct choice is the roof ladder, as this type of ladder is specifically designed to be utilized on sloped roofs, allowing firefighters to secure themselves while working at height. The design features hooks that allow the ladder to be anchored onto the peak of the roof, providing stability and safety.

When carried with the tip forward, the ladder becomes easier to maneuver and position on uneven or sloped surfaces. This orientation helps the firefighter efficiently set the ladder up in the correct position for safe access to the roof.

The other types of ladders have different handling techniques based on their specific uses. For instance, extension ladders can be carried in various orientations but typically are extended to reach higher areas, and their use may not always require a tip-forward position. Attic ladders are usually lightweight and foldable, designed for accessing attics from inside a structure, while straight ladders are simpler, single-piece ladders that can be carried in different ways depending on the situation but don't often require a tip-forward approach when being set up.
