What type of ladders consist of a base section and one or more fly sections that travel in guides for length adjustment?

1. Extension

2. Step

3. Folding

4. Fixed

The correct answer is: Extension

The correct answer is extension ladders, which are designed with a base section and additional fly sections that can be extended or retracted for length adjustment. This feature makes them particularly versatile for reaching varying heights during firefighting operations or rescue scenarios. The fly sections travel in guides along the base, allowing the user to adjust the ladder's length quickly and efficiently while maintaining stability and safety. In contrast, step ladders are self-supporting and do not extend in length; they are used for shorter tasks where height is less of a concern. Folding ladders typically have hinges that allow them to collapse for storage but do not serve the same height-adjustable purpose as extension ladders. Fixed ladders are permanently mounted and lack any extension capability, making them suitable for specific, non-adjustable applications.
