What is a characteristic of a straight/wall ladder?

A straight or wall ladder is characterized by being non-adjustable and typically consists of a single section. This design allows for straightforward use in accessing heights, such as windows or roofs, where a stable and rigid structure is needed. The one-section feature provides strength and stability, which is crucial in firefighting situations where safety and reliability are paramount.

In contrast to the other options, straight ladders do not have adjustable lengths or multiple sections, which are features found in extension ladders or aerial ladders. The singular design makes them easier to deploy in certain scenarios, but they are limited in terms of height versatility compared to ladders that can be adjusted or are vehicle-mounted. Vehicle-mounted ladders, for example, are designed for different operational requirements and offer various benefits tailored to those needs, further distinguishing them from straight ladders.
