How do I respond to a carbon monoxide alarm?

Treat every CO alarm as a real emergency. Evacuate everyone from the home immediately, including pets. Call 911 from outside. Do not re-enter until emergency responders clear the building. Carbon monoxide is odorless and colorless. Have your HVAC system and fuel-burning appliances inspected before returning.

Why It Matters

Carbon monoxide poisoning can be fatal within minutes at high levels. Never assume a CO alarm is a false alarm or a low battery warning.
