Fire Safety Guideline for Impulse (Jet) Fans in Carparks

Published: 13 July 2018

The Australasian Fire and Emergency Service Authorities Council (AFAC) have recently released Guideline 1.0 on Fire Safety for Impulse (Jet) Fans in Car Parks.

The primary objective of this guideline is to provide guidance to building certifiers, engineers, builders and installers when preparing or reviewing a proposal involving impulse (jet) fans in car parks.

The 2015 revisions of AS1670.1 and AS1668.1 have provided additional fire safety requirements when impulse fans are provided in car parks and these standards now adequately address previous concerns raised in regards to early shut down of jet fans in a fire. On this basis for buildings that are required to comply with the BCA 2016 a fire safety performance solution is not required.

Where jets fans are installed in series, a mechanical engineering performance solution will be required. The mechanical engineering performance solution should contain detailed engineering justification to demonstrate that the jet fan system will not have a significant detrimental effect on the safe egress of occupants or operation of the sprinkler system.

Fantech can provide Jet fan car park design assistance and a turn key product solution which includes integrated smoke detection and control logic to shut down the Jet fans in the very early stages of fire development as required by this doctrine.
