It doesn't matter how far your body extends above the ladder. What matters is that you do not step on the top of (highest point), or on the second from top of the ladders stepping space. You must (by Osha--or Department of labor) stand on the third most step from the top. (It specifies this on the ladder.) good question!
On an extension ladder one can climb up, then step one rung down, threading your foot thru so that the one rung is behind your knee, and the next rung lower is held by the top (dorsal) of the foot.
I believe that the std Sparky's referring to applies more to extension ladders that are used to climb to rooftops, etc. They also should be tied off at the top. (this std was part of a safety meeting held by our safety compliance consultant).
I got the Davidson 7 footer too and the 18 extension. They're very light, and rated for 225 lbs which is me (140 lbs) and all I want to carry up a ladder!
