AS 1668 Part 1, 2015 edition – The use of ventilation and air conditioning in buildings, Part 1: Fire and smoke control in buildings

AS 1668 Part 1 sets out minimum requirements for the design, construction, installation and commissioning of mechanical smoke control systems in buildings. Specific methods of smoke control are defined and the appropriate requirements specified for each.

The design information given in AS 1668.1 in respect to hot layer smoke control is based on a single axisymmetric plume, which is confined to one reservoir. Smoke plumes spilling across multiple reservoirs are not considered.

Requirements for the maintenance of smoke control systems are not included.

This Standard applies to Class 2 to Class 9 buildings where smoke control is required.

NOTES:

The Standard does not identify those buildings in which smoke control systems or pressurization systems are required. This is covered in the National Construction Code (NCC).
AS 1851 outlines management procedures for maintaining the fire and smoke control features of mechanical services.
