If you hear your carbon monoxide detector beeping, do not ignore the alarm. Leave immediately because exposure can quickly lead to health risks including heart disease or fatality. Get pets and everyone out for fresh air. Call 9-1-1 and go to the hospital immediately. Do not re-enter the home until emergency responders say it’s safe to do so.
If local emergency responders don’t find carbon monoxide in your home, try resetting your alarm. If the carbon monoxide detector sounding doesn’t stop, contact your manufacturer immediately.
