The process
Basement car parks and tunnels use jet fans and extract fans rated for smoke extract, with silencers at the discharge. The fans run on carbon monoxide sensors in normal operation and at full speed in a fire.
The gas
Ambient air with vehicle exhaust, moved by jet fans and extract fans, with the smoke extract case setting the high temperature rating of the motor.
