Power outages increase risks for carbon monoxide poisoning. Here’s how to use your generators safely

RICHMOND, Va. (WRIC) — The weekend winter storm is set to bring snow, sleet, freezing rain and the potential for widespread power outages across Central Virginia, but there's another health risk community members should be aware of amid the storm.

As residents turn to portable generators and alternative heating methods, the risk for carbon monoxide (CO) poisoning from such devices also increases and could turn dangerous quickly, the Blue Ridge Poison Center at the University of Virginia warned.

“Power outages always bring a risk of carbon monoxide poisoning,” said Christopher Holstege, the Blue Ridge Poison Center’s director. “Since you cannot see, smell, or taste CO, you may not be aware that you are breathing it.”

Per the center, as folks burn fuel in portable power generators, CO is formed. The gas can make its way inside homes if the generator is not located in a safe place.

A "dangerous" amount of CO can also build up inside homes through faulty, clogged or leaky gas furnaces or chimneys, per the center. Running vehicle engines in garages can also cause the gas to accumulate indoors.

Some other sources of CO include propane heaters, woodstoves, gasoline-powered tools and charcoal or gas grills.

The center warned residents of a variety of health risks when breathing in CO, including nausea, vomiting, chest pain and death. Very high concentrations of CO can lead to loss of consciousness in a short amount of time.

Blue Ridge urged residents to install carbon monoxide alarms. The center also warned against the usage of gas ovens, charcoal grills or camping stoves to heat homes.

If you lose power and need to use a portable generator, follow these safety tips from the Chesterfield County Fire and EMS:

• Always operate your generator outdoors and never use it inside a home, garage, basement, crawlspace or any enclosed area.
• Place the generator in a well-ventilated area and away from doors, windows and vents.
• Make sure the generator has proper airflow to reduce the risk of hazardous fumes building up.
• Keep the generator dry. Don't use it in wet conditions.
• Store fuel in approved containers away from living areas. Turn off the generator and let it cool down before refueling to avoid fire hazards.
• Plug items directly into the generator or use a heavy-duty, outdoor-rated extension cord. Make sure the cord was designed for generator use.
• Read and follow the manufacturer's instructions to operate and maintain the generator safely.
