What is the size of the extension ladder used in fire operations?

The size of the extension ladder commonly used in fire operations is typically 24 feet. This length provides firefighters with the necessary reach for accessing various building heights, including two to three-story structures. A 24-foot ladder is versatile enough for residential firefighting scenarios, allowing firefighters to reach roofs, windows, and upper floors effectively.

Shorter ladders, such as 10 feet or 14 feet, may be suitable for smaller, one-story buildings or for specific tasks like accessing the side of a fire truck or performing close proximity work, but they lack the reach needed for higher structures in many emergency situations. A 30-foot ladder, while it offers more height, can be cumbersome and less maneuverable in tight spaces, making it less favorable for general use in typical fire operations compared to the 24-foot ladder. Thus, the 24-foot extension ladder strikes an optimal balance between reach and usability in firefighting contexts.
