Carbon Monoxide

What is Carbon Monoxide

Carbon Monoxide (CO) is the result of incomplete combustion of almost any type of fuel. It is colorless, odorless, tasteless, and non-irritating. Carbon Monoxide is sometimes called The Silent Killer because when it enters the blood stream it prevents the blood from absorbing oxygen. When oxygen deficient blood reaches the heart and brain, it can damage those organs and cause illness or even death.

How do I prevent Carbon Monoxide?

  • Never operate an automobile, gas grill, lawn mower or any type of combustible engine inside your attached garage or your home
  • Have your gas appliances checked by a qualified technician regularly
  • Make sure your fresh air intakes are not blocked
  • Be sure your vents and chimneys are properly installed and free of debris, and blockage
  • Natural Gas fired appliances should have a clear blue flame, yellow or orange may indicate a problem and should be checked by a trained technician
  • Carbon Monoxide alarms should be used throughout your home

Carbon Monoxide Detectors

While some CO detectors last up to 7 years, most do not. Austin Utilities recommends that you replace your detector every 5 years. When in doubt of its age replace it. Be sure to test your detector regularly and replace batteries yearly.

Minnesota Statues require that Carbon Monoxide detectors be installed in every single family dwelling and every unit in a multifamily dwelling home.
