What is the length range of a fully extended aerial ladder?

The length range of a fully extended aerial ladder typically falls between 50 and 137 feet. Aerial ladders are designed to reach high elevations in emergency situations, allowing firefighters to efficiently access buildings for rescue and firefighting operations. This range accommodates various designs and intended applications, as different fire departments may have specialized ladders tailored to their operational needs and the types of structures they encounter.

In context, the other options present ranges that are either too short or too extensive, thus not representative of standard aerial ladder specifications. For instance, ladders that extend below 50 feet may not be sufficiently equipped for high-rise situations, while those proposed beyond 137 feet could be uncommon in practical use, limiting maneuverability and deployment in typical scenarios. Therefore, the specified range of 50 to 137 feet accurately reflects industry standards for fully extended aerial ladders.
