Carbon monoxide gas, also known as the silent killer, is a colourless, odourless, tasteless and extremely toxic gas. It can poison the body gradually in low doses or quickly when it is highly concentrated. It reduces the body’s ability to transport oxygen in blood. Symptoms of carbon monoxide inhalation are flu-like and include: headaches, dizziness, burning eyes, drowsiness and loss of consciousness. Cases of severe inhalation may result in brain damage or death.
All dwellings should be equipped with a Carbon monoxide alarm. Make sure that your detector meets the Canadian Standards Association CAN/CGA 6.19 standard or the Underwriters Laboratories UL 2034 standard. Carbon Monoxide, unlike smoke, does not rise but rather mixes with air. Detectors therefore should be placed at waist level in areas that receive undisrupted airflow. If a combination smoke/CO detector is going to be used it should be placed on the ceiling and like always close to areas where people sleep.
Make sure you replace the batteries in your carbon monoxide detector at least once every year and don’t forget to do the same for your smoke detector.
