1026.4 Refuge Area
The capacity of the refuge area shall be computed based on a net floor area allowance of 3 square feet (0.2787 m2) for each occupant to be accommodated therein.
Exceptions: The net floor area allowable per occupant shall be as follows for the indicated occupancies:
The refuge area into which a horizontal exit leads shall be provided with exits adequate to meet the occupant requirements of this chapter, but not including the added occupant load imposed by persons entering the refuge area through horizontal exits from other areas. In other than I-3 occupancies, not less than one refuge area exit shall lead directly to the exterior or to an interior exit stairway or ramp.
Exception: The adjoining compartment shall not be required to have a stairway or door leading directly outside, provided the refuge area into which a horizontal exit leads has stairways or doors leading directly outside and are so arranged that egress shall not require the occupants to return through the compartment from which egress originates.
