Q. If I am using a straight ladder, how far out from the building should the feet be placed?
A. When straight ladders or extension ladders are placed against a vertical surface, the angle shall be a ratio of one foot horizontal for every four foot vertical. When straight ladders or extension ladders are used to access roofs or similar structures, the ladder must extend at least three feet above the roof surface.
