For metal and fiberglass ladders, how should the fly be positioned?

When working with metal and fiberglass ladders, the fly should be positioned with the fly out. This configuration allows the ladder's section that extends, or the fly, to be on the outside, providing better stability and security when it is extended for use. This is especially important when accessing elevated locations, as it prevents the ladder from tipping or flexing in unexpected ways during operation.

Having the fly out also enables the ladder user to properly secure it at the base and ensures that the strongest part of the ladder is facing away from the structure or surface being accessed. This positioning takes advantage of the design of the ladder, ensuring that the extension is the most stable and provides maximum strength when weight is applied.

Other options such as "Fly in" would not offer the same level of stability and could lead to unsafe situations during firefighting operations or rescues. The statement about either position or variations by manufacturer does not apply universally as the standard practice for metal and fiberglass ladders is to have the fly out for safety and effectiveness in ladder operations.
