in.) of continuous and unobstructed space, including trip hazards along the path of exit.
Workspace : The dimensional box required for safe inspection or service of energized equipment.
It consists of depth, width, and height. The depth dimension is measured perpendicular to the
direction of access. The U.S. regulation minimum is 914.4 mm (36 in.), but additional conditions can
increase the minimum dimension requirement. GEHC defines this as the envelope of the
component superstructure with the external covers in place.
Service Access Width : The width of the workspace in front of the equipment. A minimum of 762
mm (30 in.), or the width of the equipment, whichever is greater.
Head Clearance : The height dimension of the workspace. The height of the workspace measured
from the floor at the front edge of the equipment to the ceiling or overhead obstruction(s). 1981.2
mm (78 in.), or the height of the equipment, whichever is greater.
