Get everyone out of the house immediately if a carbon monoxide detector goes off or you suspect carbon monoxide poisoning symptoms. If possible, remove all pets from the home.
Open the windows and turn off possible sources of carbon monoxide leaks only if you live in a multifamily home. If you live in a single-family home, evacuate and wait for emergency personnel to arrive. They will be able to detect the source of the carbon monoxide leak more easily if the home is not ventilated.
Ventilate the house when the emergency responders tell you it is alright to do so. More likely, the emergency responders will open all the windows themselves. Ventilation rids the home of carbon monoxide. Do not go back in your home until the emergency responders tell you it is safe.
Schedule inspections every year for your heating and hot water equipment, chimney and fuel-burning appliances. This can help detect possible carbon monoxide leaks early, before they become a serious hazard.
Check the flue of your fireplace before starting a fire. Ensure that it is open and free of obstructions. An obstructed flue can elevate carbon monoxide levels in your home.
Open the garage door before starting your car. Immediately pull it out into your driveway and close the door to prevent carbon monoxide from entering your home. Never use a remote car starter to start your engine when it's in the garage.
Avoid using kerosene space heaters or grills indoors. Never use any gasoline-powered tool inside or in your garage. During power outages, avoid using natural gas, propane stoves or other appliances for heat.
Install carbon monoxide detectors. Place at least one on each floor of your home. Use detectors that are UL-certified. Test the batteries every six months.
