What is the primary function of all aerial ladders?

The primary function of all aerial ladders is to provide access to the upper floors via the exterior. This capability is crucial in firefighting operations, as it enables firefighters to reach elevated locations where they can perform rescues, conduct searches, and fight fires from above. Aerial ladders allow for effective access to multi-story buildings, facilitating both entry and exit for personnel as well as providing a means to evacuate individuals trapped on upper floors.

While aerial ladders can also serve additional functions, such as supporting firefighting operations and assisting in salvage efforts, their main design and intended purpose focus on improving access and egress in situations where ground-level entry is insufficient or impossible. This specialized function highlights the importance of aerial ladders in urban firefighting and emergency response.
