Winter storms and cold temperatures can create potentially dangerous conditions in and around your home, including some impacting indoor air quality. Extreme cold and icy conditions can lead to burst pipes. Heavy snow and ice can block furnace and other vents and pipes in your home that can cause buildup of harmful pollutants indoors, like carbon monoxide. Follow the tips and safety precautions below to prepare for potential severe winter weather.
Check Your Smoke Detector and Carbon Monoxide Alarm
Carbon monoxide (CO) is an invisible and odorless gas which comes from a variety of combustion appliances, like gas stoves, ovens or barbeque grills. CO can build up quickly indoors and can linger for hours. At elevated levels, CO can quickly cause significant harm and even death.
 Test smoke detectors and CO alarms monthly and replace batteries in these devices at least once each year, unless they have sealed 10-year batteries. Replace the smoke detector or CO alarm if it is more than 10 years old. Check that smoke detectors are installed inside each bedroom, outside each sleeping area, and on every level of the home, including the basement. Check that CO alarms are installed outside each sleeping area and on every level of the home to prevent CO poisoning. Learn more about Carbon Monoxide’s Impact on Indoor Air Quality |
