As temperatures decline and residents turn up thermostats, UGI urges customers to take several steps to ensure proper operation of natural gas heating equipment and appliances to prevent a build-up of carbon monoxide (CO) inside homes.

CO is a colorless, odorless, poisonous gas that is a byproduct of the incomplete combustion of fuels such as wood, charcoal, gasoline, kerosene, oil, natural gas, and propane. CO can be caused by malfunctioning heating systems or appliances as well as damaged or blocked vents and chimneys.

Indicators of CO poisoning include flu-like symptoms such as headache, nausea, and dizziness, as well as fatigue and shortness of breath. Individuals who think they might be experiencing CO poisoning should immediately seek fresh air and prompt medical attention.

Here are some simple steps to help ensure your safety:

• Make sure smoke and carbon monoxide detectors are working properly. CO detectors/alarms should be located on each floor of a home, including one in each bedroom, or sleeping area.
• Have a qualified professional check your furnace, water heater, and other internal combustion appliances annually.
• Check the connections to your chimney or flue for damage or corrosion. Contact a heating professional to have your chimney and flue checked.
• Verify that both internal and external combustion air vents are unobstructed. External vents can become blocked by leaves and other debris.
