Carbon Monoxide: The Silent Killer.
Carbon monoxide (CO) is a colorless, odorless deadly gas. Because you can't see, taste, or smell it, carbon monoxide can kill you before you know it's there.
Everyone is at risk for carbon monoxide poisoning. Experts believe, however, that individuals with greater oxygen requirements such as unborn babies, infants, children, senior citizens, and people with coronary or respiratory problems are at greater risk.

Reliable Security can install a Carbon Monoxide Communicator to alert the monitoring center in the event of a dangerous leak. Common sources for this silent killer can come from defective furnaces, blocked fireplace flues or even a car engine that has been left running in a garage.
