A carbon monoxide detector could mean the difference between life and death, says LaPrade. Detectors are sold at home improvement centers, department stores, hardware stores, discount stores and some drug stores. To reduce the risk of carbon monoxide poisoning, LaPrade suggests annually inspecting homes and appliances that run on fossil fuels to ensure they are properly ventilated. In some cities, fire department personnel will check homes or businesses for carbon monoxide leaks at no cost. Never use charcoal burning grills inside a home.
Charcoal gives off large quantities of carbon monoxide while burning.
Although heating costs are an important consideration during these cold winter months, homes shouldn't remain so tight that air circulates poorly. Leaving a window slightly ajar could make a big difference.
