To protect the worker exiting a ladder osha requires a 42 inch high grab bar extension above the access level or landing platform at the top of the ladder. This is the same height that osha requires for guardrails.

Note that this is more than the 3 feet a portable ladder needs to extend above a landing or the 3 feet high a hand grab has to be for a portable ladder. For parapet ladders the access level is. For fixed ladders consisting of wood side rails and wood rungs or cleats used at a pitch in the range 75 degrees to 90 degrees and intended for use by no more than one person per section single ladders as described in 1910 25 c 3 ii are acceptable.
