Never ignore an alarming Carbon Monoxide (CO) alarm! It is warning you of a potentially deadly hazard.
If the alarm signal sounds do not try to find the source of the CO:
- Immediately move outside to fresh air.
- Call your emergency services, fire department, or 911.
- After calling 911, do a headcount to check that all persons are accounted for.
- Do not reenter the premises until the emergency services responders have given you permission. You could lose consciousness and die if you go into the home!
- If the source of the CO is determined to be a malfunctioning appliance, do not operate that appliance until it has been properly serviced by trained personnel.
If authorities allow you to return to your home, and your alarm reactivates within a 24 hour period, repeat steps 1, 2, and 3 and call a qualified appliance technician to investigate for sources of CO from all fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this inspection, have the equipment serviced immediately.
