What is the typical length range for combination ladders?

Combination ladders, which can function as both extension ladders and A-frame ladders, typically have a specific length range that allows for versatility in various firefighting and rescue situations. The correct answer indicates a length range of 6-10 feet for A-frame configurations and 10-15 feet for extension configurations.

This range reflects common ladder designs that balance portability with functionality. The A-frame of a combination ladder is designed for stability and ease of use at shorter heights, making it ideal for tasks such as accessing low rooftops, windows, or working in tight spaces. The extension aspect accommodates higher reaches, ensuring firefighters can effectively carry out their operations when more elevation is required, such as reaching higher floors of a building or working from a safe distance.

Understanding these length specifications is essential for safe operation, as firefighters need to ensure they are using the appropriate ladder for the task at hand while considering safety in terms of both stability and reach.
