As of the 2018.i version, the indoor compartmentation (zones that are divided into smaller compartments using vertical partitions with a specific fire resistance) can include the following requirements:
- Fire smoke control
Required installation of fire smoke controls in the zone. - Communication with other zones via safe zones
This requirement could already be activated for certain types of zones. Now, it can be activated so the indoor compartmentation has, at its communication point with other zones or adjacent indoor compartments, a valid safe zone for the communication (such as independent lobbies).
