Abstract
A ladder assembly is provided, including the following: a mounting plate that connects to a side surface of a module in a fabrication facility; a step ladder, including, a ladder frame having an arm that connects to the mounting plate at a first joint, wherein the step ladder rotates about the first joint between a lowered position and a raised position, the lowered positioned defined by resting of the step ladder on a floor of the fabrication facility, and the raised position defined by suspension of the step ladder off of the floor and substantially over the module; a plurality of step plates connected to the ladder frame, the step plates defining step surfaces for a user when the step ladder is in the lowered position. A sleeve extends below one of the step plates of the step ladder, to house electronic equipment used in the fabrication facility.
