What symptoms can occur from carbon monoxide exposure?

If you’re occupying a space where fuel is burned and fumes have an opportunity to build up, you’re at risk for carbon monoxide (CO) poisoning. CO is an odorless, colorless gas that’s hazardous to inhale, causing uncomfortable symptoms at low levels and death at higher levels. EMS, EMT, police and fire departments face this potential danger when responding to reports of flu-like illnesses or unconscious citizens who may be involved in CO poisoning themselves.  Avoid workplace injuries by knowing what symptoms to look for and how to prevent CO poisoning.


CO poisoning symptoms can feel flu-like, and their severity depends on your exposure, which is measured in parts per million (ppm). If you or your employee experiences symptoms, get into fresh air immediately and get emergency medical help.

  • 35 ppm: Within 5 to 8 hours, you’ll experience headache, dizziness, and flushed skin
  • 200 ppm: Within 1.5 to 3 hours, nausea, headache, dizziness, and very red skin
  • 400 ppm: After 3 hours, exposure becomes life-threatening
  • 800-1,000 ppm: After an hour, loss of consciousness and seizures happen; after 2 or 3, death occurs
  • 3,200 ppm: Unconsciousness occurs within 30 minutes
  • 6,400+ ppm: Instant unconsciousness, death in 10-15 minutes
