How should corridors in Group I-2 occupancies be constructed and maintained according to the 2018 International Building Code?

Corridors in Group I-2 occupancies must be continuous to exits and separated from other areas as specified in Section 407.3. They should be constructed as smoke partitions and equipped with an automatic fire detection system. Corridor doors should limit smoke transfer and have positive latching, but do not require a fire protection rating or self-closing devices.

In Group I-2 occupancies, corridors must be continuous and lead directly to exits, ensuring a clear path for evacuation. They must be separated from other areas according to Section 407.3, which requires them to be constructed as smoke partitions. An automatic fire detection system is mandatory for corridors and spaces open to them, enhancing fire safety. While corridor doors need to effectively limit smoke transfer and have positive latching, they are not required to have a fire protection rating or self-closing devices, unless specified otherwise for certain walls or vertical openings.
