🔥🪜 FIRE SERVICE EXTENSION LADDER Are essential tools for rescue, access, ventilation, and rapid movement during firefighting operations. Among them, the extension ladder is one of the most versatile, built to reach heights that single ladders cannot. The extension ladder is a non–self-supporting, adjustable-length ladder made of two or more sections that slide and lock into place. It allows firefighters to reach windows, roofs, and upper levels quickly while maintaining stability and strength.
