What is carbon monoxide (CO)?

Carbon monoxide is an odorless, colorless and toxic gas. Because it is impossible to see, taste or smell the toxic fumes; CO can kill you before you are aware it is in your home. At lower levels of exposure, CO causes mild effects that are often mistaken for the flu. These symptoms include: 

  • Disorientation
  • Dizziness
  • Fatigue
  • Headaches
  • Nausea

The effects of CO exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure.
