The Illinois Poison Center announces that winter can bring an increase of carbon monoxide poisoning. Carbon monoxide poisoning is called the “silent killer”, because it cannot be seen, smelled or tasted. Poison Center officials urge that residents have a functioning Carbon Monoxide detector at their homes. Carbon Monoxide poising can occur at anytime during the year, without the homeowner knowing. The risk increases as the weather outside grows colder, and people turn on their furnaces and gas-powered appliances for heating. Gas heating appliances are the leading cause of Carbon Monoxide injuries, with other appliances including oil or wood heaters, charcoal grills, lanterns, and gas-powered engines. The Poison Center recommends that you install a carbon monoxide detector on each floor of your home. They also ask that you have all furnaces and heating equipment inspected annually by a professional.
