The following may answer most questions should the CO detector alert:

  • Be aware of what your CO detector is alerting you to when it sounds.  Different manufacturers have alerts set at varying levels of CO. Some may be alerting you to low levels or possibly even extremely high levels, consult your manual supplied with the detector.
  • Classic signs and symptoms of CO poisoning would be headache, nausea, dizziness, tiredness, and possible vomiting
  • Slightly crack a few windows to provide ventilation if CO is suspected.
  • If not an emergency, contact the appropriate service repair agency to fix the problem as soon as possible.
  • If you do suspect a CO presence, contact the Bemidji Fire Department.
