CASE 3: Side Acting with Conventional Egress Door(s) and Vertical Coiling with Complying Swing Egress Door(s)
Smoke barriers divide areas of a building into separate smoke compartments. These dividing walls allow time for building occupants to be evacuated or relocated to other smoke compartments. In other words, smoke barriers separate portions of buildings into areas of refuge capable of resisting the passage of smoke and fire for up to 1 hour. (Section 709)
These two very different technologies converge on the inside corner of the structure to complete the smoke barrier separation creating separate refuge area compartments. Operating as duel function assemblies they are also located to separate the corridors from additional spaces.
