(that intersect the pedestrian walkway) strobe lights are placed at the intersections
so that pedestrians will know when a truck is pulling in or out of the loading dock. In

per square foot and should extend at least 30 feet out from the hoist structure. It is best
to check with the local jurisdiction to determine their requirements.

In some areas, on the first floor it may be necessary to enclose a linear portion of the
space. In this instance, a shed is provided. The shed is used to help keep out the public
and minimize the infiltration of adverse weather elements. The shed is usually con-
