Which ladder type can be extended to reach higher areas?

The extension ladder is specifically designed to be extended in length, enabling it to reach higher areas that standard, non-extendable ladders cannot. It consists of two or more sections, which slide past one another. This unique feature allows firefighters to adjust the ladder's height according to the specific demands of the situation, making it particularly useful for accessing rooftops or elevated positions during emergency operations.

Other ladder types, such as folding, step, and attic ladders, have fixed heights or limited extendable capabilities that do not allow them to reach significant elevations like an extension ladder. Folding ladders are primarily for storage and transport convenience, step ladders are designed for stable access to moderate heights but do not extend, and attic ladders are used for accessing attic spaces but do not provide the reach offered by extension ladders. This makes the extension ladder the ideal choice for reaching higher areas effectively and safely.
