This standard sets forth safety requirements for areas where danger exists of persons or objects falling through floor or wall openings, platforms, runways, ramps, and fixed stairs, in normal, temporary, and emergency conditions. This standard applies to industrial and workplace situations and is not intended to apply to construction, residential, or commercial occupancies except where necessary maintenance or work station access may be required. Recognizing that the special safety requirements necessary for stages, orchestra pits, churches, school auditoriums, and athletic assembly occupancies may not be adequately covered by other codes or standards, this one may provide the minimum safety performance requirements to protect the occupants.
