Exhaust fumes emanating from fuel burning vehicles are highly toxic and can result in sickness and even death, if not ventilated properly.  By monitoring the concentration of these fumes and ventilating based on their concentration, a safe environment

can be ensured.  These practices aid in reducing building liability and meeting Occupational Health and Safety Act, Part III. Regular service of your gas detection system per the manufacturer’s recommendation by specially trained technicians assist you in providing a safe, healthy, and energy efficient environment for your workers, your customers, and the public.


The Ontario Building Code indicates that ventilation for parking structures should be continuous, 24/7, unless a system is in place to ensure hazardous gas concentrations are kept below prescribed levels.  By ventilating only when CO sensors indicate a requirement, there is an opportunity for significant energy savings from reduced fan operation and reduce wear and tear of equipment.
