What is defined as the butt of a ladder?

The butt of a ladder refers specifically to the end of the ladder that is placed against the ground. This part is crucial for stability when the ladder is in use, as it helps to ensure that the ladder maintains its position and does not slip or tip over. When setting up a ladder, firefighters and other users must ensure that the butt is secure and positioned correctly to provide a safe ascent and descent. Understanding this terminology is essential for effective communication and safety in firefighting operations, as well as for the proper handling and positioning of ladders.
