Carbon Monoxide and Parking Garage Ventilation Systems

The ventilation system for the phase 1 garage consists of an exhaust fan that operates at a constant volume 24/7. The phase 2 garage has a more complex system that consists of an exhaust fan with a variable speed drive (VFD) connected to CO sensors throughout the space. This fan is set to run 24/7, but the speed varies based on the level of CO.

NFPA - Carbon monoxide alarms

Often called the invisible killer, carbon monoxide is an odorless, colorless gas created when fuels (such as gasoline, wood, coal, natural gas, propane, oil, and methane) burn incompletely. In the home, heating and cooking equipment that burn fuel are potential sources of carbon monoxide. Vehicles or generators running in an attached garage can also produce dangerous levels of carbon monoxide.
