I am trying to understand the life safety requirements of an old legacy hospital at the time it was constructed. I have found references in the 1963 and 75' Southern Standard Building Code (SBC) requiring the Institutional Group D occupancy to have "All partitions shall be of not less than one-hour fire -resistive construction." under 702.3 Partition Requirements By Occupancy. Was it really the intent that all walls were one-hour rated? The mechanical drawings do not show dampers everywhere. What determines which one hour walls get dampers? It appears that this section later (by 79') required non-combustible construction (for Type I and II) and referred to Table 700 for ratings and opening protectives.
