How can I prevent carbon monoxide poisoning?

Protect yourself and family members from carbon monoxide poisoning:

– Do not use fuel-burning heaters in un-vented enclosed spaces.

– Make sure your house has functioning carbon monoxide monitors with fresh batteries.

– If a monitor goes off, do not consider it a false alarm. Open all windows to ventilate, and call a technician to check the heating system and ensure all is working properly.

– Do not ignore anyone with symptoms; seek medical help in an ER immediately.

– First aid for victims: remove them from the contaminated area to fresh air or give oxygen if available.
Besides installing a carbon monoxide detector, take additional steps to ensure your family’s safety by inspecting and servicing these potential sources of CO poisoning:
  • Check filters and filtering systems for blockages and dirt.
  • Have a professional check possible dangers such as too high a concentration of CO in the flue gases or cracks in the combustion chamber.
  • Look at the burners and ignition system. If the flame is mostly yellow in a natural gas-fired furnace, this may be a sign that fuel is not burning completely and releasing too high a level of CO.
Venting systems to the outside: Flues, chimneys, and clothes dryer vents
  • Check chimneys for nests that may block gas from escaping.
  • Check chimneys for proper installation, cracks, corrosion, holes, and debris.
  • Check outside dryer vents for lint buildup.
Appliances that use flammable fuels such as oil, wood, kerosene, or natural gas
  • These can include clothes dryers, kitchen ranges, ovens, and water heaters.
  • Check pilot lights since malfunctions can release CO inside the home. Monitor gas stoves and ovens closely.
Space heaters
  • Check to make sure these are vented properly.
Barbecue grills
  • Do not use these indoors.
  • Do not use these in an attached garage, even with the door open.
  • Do not use these outside an open window.
