Carbon monoxide (CO) is a colorless, tasteless and odorless gas produced by incomplete burning of carbon-based fuels, such as coal, gas, oil and wood. It can enter your body when you breathe in air, and it can kill you quickly without warning. Every year in the United States, around 500 people die as a result of accidental CO poisoning, many in their own homes.
CO poisoning is deadly as its signs and symptoms are not always obvious, especially during low-level exposure. The most common symptoms are headache, nausea, dizziness, shortness of breath and tiredness, all of which are similar to those of other conditions, including food poisoning and influenza.
The best way to protect against CO poisoning in your home is to be aware of carbon monoxide dangers, and to identify appliances that could emit CO. Most cases of CO poisoning in the home result from improperly installed or poorly ventilated gas appliances and flues, so it is vital to ensure your appliances are installed and regularly serviced by a reputable engineer. If you have a chimney, instruct a licensed chimney sweep to check and sweep it at least once a year. A blocked chimney can cause CO to build up inside your home.
One of the most important ways you can protect yourself against CO poisoning is to install a carbon monoxide alarm in your home. This will provide you with an early warning if there is a CO leak in your home.
If you suspect CO may be escaping from your appliances, or your carbon monoxide alarm goes off, immediately stop using any appliances that use fuel, open all windows and doors to ventilate your home and leave your home immediately. Call the emergency services straight away and do not return home until the emergency services have given you permission. Visit your doctor and inform them that you have been exposed to CO in your home. Prompt medical attention is important, even if you feel well.
The effects of CO poisoning can be devastating but they are easily preventable. By taking some simple precautions, you can avoid falling victim to this silent killer.
