Carbon Monoxide (CO) is an invisible, odourless and tasteless gas that is toxic to humans and animals, not to be confused with Carbon Dioxide (CO2). In various countries, thousands of people are treated in hospital for CO poisoning every year. It is often referred to as the “Silent Killer” because we can’t smell it, taste it or see it. The initial symptoms of CO poisoning are tiredness and headaches, similar to a cold or flu, but long exposure, or high levels, will lead to confusion, fatigue and unconsciousness, and can be fatal within hours. CO is produced when appliances that use carbon-based fuels malfunction and don’t burn correctly, or have blocked or broken flues. The gas ovens and boilers, open fires, BBQs and car exhausts can all pose a CO risk to your family. Who is at risk? Everyone is at risk of CO poisoning in the home, but children, the elderly, and pets are extremely vulnerable. Ensure fossil fuel-burning appliances are serviced regularly and install a CO alarm alongside each one in a property.
