What actions do I take if my carbon monoxide detector goes off?
If no one is feeling ill:
  • Silence the alarm.
  • Turn off all appliances and sources of combustion (i.e. gas furnace, fireplace, gas dryer, hot water heater, etc.)
  • Call 9-1-1 to investigate the source of the possible CO buildup.

If illness is a factor:
  • Evacuate all occupants immediately.
  • Determine how many occupants are ill and determine their symptoms.
  • Call 9-1-1. When relaying information to the dispatcher, include the number of people feeling ill.
  • Do not re-enter the home without the approval of a Fire Department representative.
