As we spend more time inside our homes in the winter, with doors and windows tightly closed, we become more at-risk for carbon monoxide poisoning. Because the potentially lethal gas is colorless and odorless, you may not realize you are being exposed to it. Here are the symptoms. Early symptoms are a dull headache, a feeling of weakness, dizziness, and shortness of breath. That will be followed by nausea, blurring vision, and a state of growing mental confusion. It is essential that at any of these stages you must get out of the toxic air. Either leave your home or open windows to allow fresh air in, even if it is really cold air. Then call 911 and report your situation. We advise that you install a carbon monoxide detector in your basement, about 15-20 feet from your furnace, an additional one at the top of your basement stairs, and also install one in each bedroom. You can purchase and install them yourself, or call us at 610-593-5129 and we can install them for you.
