Maintaining natural gas appliances is the best way to ensure they are operating efficiently. If your appliances are not operating properly or not properly ventilated, they may produce carbon monoxide (CO) resulting from incomplete combustion. Your natural gas flame should be blue with a hint of yellow near the tip. A yellow flame may indicate incomplete combustion and is potentially dangerous. Call a qualified contractor if you suspect your appliances are not operating properly.

CO is a colorless and odorless toxic gas that can be fatal. Initial symptoms are similar to the flu (but without fever) and may include nausea, fatigue, dizziness, or headaches.

Home Safety Tips:

  • CO detectors are not required but are recommended - be sure to check the batteries annually.
  • Follow manufacturer instructions for the care and use of gas appliances and equipment.
  • Have your gas appliances installed and serviced by qualified industry professionals.
  • Inspect all gas appliances, connectors, furnaces, vents, flues, chimneys, and gas lines to your home. Replace if necessary.
  • Replace furnace air filters monthly throughout the heating season.
  • Never operate gasoline powered engines or charcoal grills in closed garages, basements, or buildings.

If CO poisoning is suspected, get fresh air immediately, seek medical attention as necessary, and call the City of Mesa at 480-644-4277 or 911.
