To complement our capabilities in design of ventilation and smoke management systems, Stacey Agnew continues to develop its own equipment and instrumentation, offering an on-site testing service, generating cold and hot smoke to visualise flow and demonstrate smoke control capability on commissioning. The heat involved can be anywhere from a few kilowatts up to 2.5 MW, using either methylated spirits or LPG. We can generate enough tracer smoke to obscure most of a ventilated road tunnel cross section.
For industrial ventilation applications, smoke can be used to qualitatively assess or demonstrate:
Where modelling has been used to design a ventilation system, smoke testing can provide a means of validating the results.
Stacey Agnew’s facilities for smoke management testing and emergency exercises include:
Stacey Agnew developed the RDP and SAM in response to an industry need for safely simulating more realistic vehicle fires for assessing tunnel systems and operational response. The benefit of SAM is that he is fully self-contained, thereby minimising the setup time of any smoke test.
Stacey Agnew has developed specific processes and procedures for managing risks associated with hot smoke tests in enclosed spaces such as tunnels. The smoke used in all tests is non-toxic. Heat effects are managed through appropriate planning and engineering of the test. While we can test to the Australian Standard, we believe that AS4391 needs improving for reasons explained here. Feedback on our thoughts is welcome by phone or email.
SAM has played a key role in emergency exercises in the Clem7 and Airport Link Tunnels in Brisbane, Australia (training video extracts below) and has generated warm smoke for ventilation mode testing in Brisbane’s Queen Street Bus Station.
