Which type of ladder is designed for rescue operations and mounted on fire apparatus?

An aerial ladder is specifically designed for rescue operations and is mounted on fire apparatus. This type of ladder can extend high above ground levels, allowing firefighters to reach individuals trapped in upper floors of a building or in difficult-to-access areas. Aerial ladders are equipped with features such as the ability to rotate, reach various angles, and position firefighters for effective rescue and firefighting efforts from elevated positions.

In contrast, extension ladders are primarily designed for manually raising to varying heights but are not mounted on fire apparatus. Portable ladders can refer to a variety of ladder types that can be easily transported but lack the specialized capabilities of an aerial ladder. Service ladders are typically used for maintenance tasks in buildings and are not intended for emergency rescue. The design and functionality of aerial ladders make them essential tools for efficient rescue operations in fire service.
