Smoke test Car Park Ventilation at Avon Fire and Rescue Sevice HQ

In 2004 Colt carried out comparative full-scale tests (PDF, 3 Mb) in an underground car park in Bristol, UK. The purpose of the tests was to demonstrate that the impulse and induction systems can provide an equivalent performance to traditional ducted systems. The tests showed that there was infact a significant improvement in the time taken to clear the car park of smoke when using the new systems compared with traditional ducted systems.
