Atrium Smoke Control
An atrium smoke control system is required to be installed in buildings when an atrium is constructed under the Building Code of Australia Part G3 Atrium Construction, clause G3.8 Fire and smoke control systems. The atrium smoke control system must be installed in accordance with Specification G3.8 to be ultimately nominated as an essential safety measure by a building surveyor/ building certifier.
Building Code of Australia
A fire emergency in a building containing an atrium provides extra risks to the occupants of the building. An atrium smoke control system is installed to provide sufficient time to evacuate the building before smoke reaches an untenable level. Most atrium smoke control systems, egress paths and floor areas mean that a fire engineered alternative solution is provided to the building surveyor/ certifier at approval stage. Approvals issued for atrium smoke control systems contain conditions in a building permit.
