Smoke Lobbies under BCA Part D1: Clause D1.7

AUST  Hendry advises for protection of occupants in a building using a fire-isolated stairway during a fire, the Building Code of Australia requires the installation of a smoke lobby between the general floor area of the storey and the exit door to the stair. A smoke lobby would be nominated in the building surveyor‘s essential safety measures determination/ schedule before occupancy occurs.

/ BUILDING CODE OF AUSTRALIA
Part D1 Provision for escape, clause D1.7 Travel via fire isolated exits, specifies when a smoke lobby is required. A smoke lobby must be constructed in accordance with Part D2 Construction of Exits, clause D2.6 Smoke lobbies. A smoke lobby/smoke lobbies requires its doors to be smoke doors that are either self closing or are fitted with automatic closing facilities linked to the building’s detection system.

The following extract of Clause I1.1 Safety Measures covers smoke lobby/smoke lobbies:

Safety Measures BCA provisions for determining standard of performance
Elements required to be non-combustible, provide fire protection, compartmentation or separation D1.7
Smoke doors and associated self-closing, automatic closing and latching mechanisms D2.6

/ ESSENTIAL SAFETY MEASURES AUDIT
Most building surveyors will nominate smoke lobby/smoke lobbies and smoke doors as an essential safety measure and will more than likely nominate a 12 month inspection routine (smoke door inspections). The essential safety measures auditor must check the overall integrity of the smoke lobby, this includes walls, doors and ceilings. Any deficiencies noted during an inspection should be recorded in the building’s essential safety measures logbook.
