Deadly Gases in Your Home: Carbon Monoxide and Radon

Dangerous gases may be lurking inside your home. Most people are familiar with carbon monoxide (CO). This deadly gas is colorless, tasteless, and odorless. Each year, unintentional CO poisoning results in over 400 deaths in the U.S. There are several sources of CO in your home. These include fuel-burning appliances like water heaters, heating systems, space heaters, generators, and fumes from vehicles idling in an attached garage. The most common warning signs of CO poisoning are headache, fatigue, nausea, shortness of breath and confusion. If someone is displaying these symptoms, get them outside the house immediately then call 911. There are several simple things you can do to prevent CO poisoning. One of the most important things is to install a battery operated CO detector or one with battery backup near sleeping areas.

Each year approximately 21,000 deaths in the U.S. occur because of radon. Like CO, radon is invisible, tasteless, and odorless. Unlike CO, the effects of exposure to radon take longer to see. Over time some people can develop lung cancer as a result of exposure to radon; whereas the effects of exposure to CO occur much sooner. Because of this, radon is often overlooked.

Breathing high levels of radon over time can cause lung cancer.
