For a wooden extension ladder, how should the fly be positioned?

In the context of a wooden extension ladder, the fly is the movable section that extends to reach greater heights. For proper use and stability, the fly should be positioned in. This means that when the ladder is set up, the fly section is closest to the building or surface both for safety and to ensure that the weight distribution and stability of the ladder are optimized. This positioning helps to maintain the structural integrity of the ladder and ensures a stronger grip against the surface it is leaned on, reducing the risk of shifting or falling.

When the fly is positioned in, it prevents the tendency for the ladder to kick out or become unstable, which is particularly important considering the weight and leverage involved when firefighters are working at height.

Other choices might suggest that the fly should be out, which could result in less stability and a greater risk of accidents. The notion that the fly could be either position or that it depends on the type of wood does not take into consideration the fundamental safety principles that are required for effective ladder placement and usage in emergency situations. Proper training emphasizes that for maximum safety and efficiency, the fly must always be positioned in.
