What must a pair of opposite-swinging doors in a Group I-2 corridor not have?

In a Group I-2 occupancy, which includes facilities such as hospitals and nursing homes, specific requirements are put in place for the safety and accessibility of patients and occupants. One critical aspect is the design and function of doors within these corridors.

For opposite-swinging doors, having an undercut exceeding 3/4 inch poses significant issues. Undercuts are the gaps at the bottom of doors, and if they exceed 3/4 inch, it can potentially allow for smoke, fire, or sound to penetrate from one side of the door to the other. This compromises the integrity of fire-rated assemblies and the overall safety of the environment.

Thus, it is crucial that opposite-swinging doors do not have undercuts exceeding this specified measurement. Having a proper undercut is essential to maintain the necessary barriers for both life safety during emergencies and the peaceful environment required in patient care settings.
