Did you know there could be a “Silent Killer” in your parking garage?  This killer is invisible, it’s colorless, it’s odorless and it’s tasteless.  Do you know what this killer is?  For those of you who don’t know what it is, it’s Carbon Monoxide (CO).  This is extremely toxic and it affects it’s victims in such a way that they may fail to recognize the dangers until it’s too late!  This is a product which occurs in internal combustion engines and when burning wood or fossil fuels.  Just 0.02 percent CO concentration in the air during a four-hour exposure period and it can cause severe effects such as nausea, dizziness, headaches and impaired judgment.  In a parking garage Carbon Monoxide can build up quickly!


What should a facility with a parkign garage do?  Add a zoning system with CO sensors.  Zoning allows multiple sensors mounted within an area into a single zone.  Sensors detect the gas and then activates the ventilation system to rid ehte area of a harmful situation.  This system can also detect where the (CO) Carbon Monoxide is building.  The fan operation of the system for that area will turn on opening the vents to release the CO.  Depending on the PPM level (Parts Per Million) if the CO levels reach 50 PPM the low speed fans are activated and if the saturation of CO reaches 150 PPM and above the High speed ventilation fans are activated for about 15 minutes.  This should allow the air in that area to be at a safer level for the people walking or working in the garage area.

For safety reasons property managers, owners and occupants should be aware that these sensors should be calibrated once a year and the motor and fans should also be serviced twice a year to make ensure proper operation.

Don’t allow anyone to be a victim of this “Silent Killer”.  When looking for an HVAC Maintenance Agreement, the garage area for this area should be added to your Maintenance Contract.  Are you covered from the risk of a silent killer? Don’t be a victim, take precautionary measures and make sure your sensors, motors and fans are functioning properly.
