 Hello, I'm Anne-Marie Burkle, Acting Chairman of the Consumer Product Safety Commission. During cold winter months, it's important to protect your family from deadly carbon monoxide poisoning. Carbon monoxide, or CO, is called the invisible killer. You cannot see it or smell it. This poisonous gas can come from your fuel-burning household appliances, including furnaces, fireplaces, and portable generators. Let's talk about some tips to avoid carbon monoxide poisoning. Your portable generator. Never use portable generators inside your home, basement, or garage. CO from generators can quickly build up and kill you and your family in minutes. Only use generators outside of your home, at least 20 feet away from windows, doors, and vents. Your car. Never leave the car running in a garage, even with the garage door open. Your heating system. Have your heating system inspected and serviced every year by a professional. Your fireplace. Make sure your fireplace damper is opened while you're using the fireplace, and keep it open until the ashes are cool. Your CO alarm. Install carbon monoxide alarms on every level of your home and outside sleeping areas. If you experience a headache, fatigue, nausea, or vomiting, and you think it may be from CO poisoning, get outside immediately for fresh air, and then call 911. From all of us at CPSC, stay warm, safe, and healthy this winter season.
