What to Do When a CO Alarm Sounds

Carbon monoxide is invisible and odorless. Do not wait for symptoms or search for the source when an alarm indicates CO.

Call (303) 880-9881 See flat pricing

Move everyone to fresh air

Leave the home immediately and account for household members at a safe location. Take symptoms such as headache, dizziness, weakness, nausea, vomiting, chest pain or confusion seriously.

Call 911

Tell the dispatcher that a carbon monoxide alarm sounded and report any symptoms. Follow emergency instructions and do not go back inside to silence the unit.

Do not assume a false alarm

A detector can be the only warning because CO has no smell, color or taste. The absence of visible smoke does not make the situation safe.

Maintenance is a later step

After responders clear the home, follow their direction regarding appliances and alarms. Detector Inspectors can help with routine detector testing and replacement, not source diagnosis or emergency clearance.
