The top of a ladder must extend how many feet above the surface a worker is climbing onto?

From the US OSHA Construction standards:1926.1053(b)(1)When portable ladders are used for access to an upper landing surface, the ladder side rails shall extend at least 3 feet (.9 m) above the upper landing surface to which the ladder is used to gain access; or, when such an extension is not possible because of the ladder's length, then the ladder shall be secured at its top to a rigid support that will not deflect, and a grasping device, such as a grabrail, shall be provided to assist employees in mounting and dismounting the ladder. In no case shall the extension be such that ladder deflection under a load would, by itself, cause the ladder to slip off its support.

How do you use an aluminum extension ladder?

Before use, perform a thorough inspection and look for damage, bent rungs, grease on tread, defective feet, etc. Follow the labels on the ladder and the owner's manual. If you don't have the manual you can download a copy from the manufacturer's website. When you set the ladder, keep clear of electrical lines, Lean the ladder against the structure at a 4:1 (with your toes at the base of the ladder, your fingertips should touch the ladder with your arms extended). Check that the surface is firm and level. If the ground is soft, you can lay down a plywood square so the ladder won't sink. Check that the ladder won't kick out. If you are on hard pavement, ensure that the feet have the rubber tread down. Some ladders have "claws" on the feet that can be flipped to bite into the dirt. Extend the ladder so that it is between 3 and 4 feet above the top of the structure if you need to step off the ladder onto a roof. Secure the top of the ladder to the structure with a rope, strap or chain so the top won't slide. Maintain 3 points of contact while you climb. Always climb facing the ladder. Don't overload the ladder. Add your weight and what you are carrying up the ladder. Never put 2 people on the ladder at the same time.
