1. A work platform for use with an aerial work platform, said work platform comprising:
a deck having a floor and a guardrail assembly, said guardrail assembly extending upward from said floor, said guardrail assembly being at least partially peripherally disposed relative to said floor, said guard rail assembly including an upper section having three sides that are movable between a lowered position and a raised position;
a work step operatively associated with said guardrail assembly, said work step being movable between a storage position wherein said work step generally does not interfere with movement on said floor and a work position in which said work step is horizontally oriented above said floor so as to upwardly dispose a step surface of said work step for use thereof;
one or more pivoting devices connecting said work step to a deck attachment member associated with said guardrail assembly, said one or more pivoting device selected to pivot said work step between said storage position and said work position relative to said guardrail assembly;
a step support mechanism associated with at least one of said guardrail assembly, said floor and said work step, said step support mechanism structured and arranged to support said work step in said work position, wherein the upper section of said guardrail assembly in the raised position provides safety to a worker standing at an elevated position on the work step in the work position; and
an operator control station located entirely within said guardrail assembly, and when said guardrail is in said lowered position, the operator control station mechanically prevents the work step from pivoting to said working position.
