Carbon Monoxide Alarms

Carbon monoxide (CO) is a colourless odourless gas that mixes freely with the air.

CO alarms are important life saving devices that are designed to provide early warning to you and your family during potentially life threatening situations. It is imperative that CO alarms are installed in the correct location, which is near the sleeping area.

However, most people take these devices for granted.

Did you realize that while you are asleep, your senses, including smell, are greatly diminished? Or that carbon monoxide, either due to a faulty appliance or as a result of smoke in a fire, can actually put you into a deeper sleep, one that you may not awaken from? These are just two of the reasons that every home should be equipped with properly installed and maintained CO alarms.
