Carbon monoxide (CO) is a colorless and nearly odorless gas created by the incomplete burning of solid, liquid, and gaseous fuels. It’s poisonous to people and pets, so be careful. Symptoms of the poisoning are: • Headache • Fatigue • Shortness of breath • Nausea • Dizziness To prevent CO poisoning, take these precautions at work and at home: • Buy and install a CO alarm. Make sure it meets safety requirements, and follow the directions for proper placement and installation. • Install appliances properly. Most of them should be installed by a professional. • Check your appliances. Have your heating system inspected and serviced every year. • Only burn charcoal outdoors. Never burn it in a tent, home, garage, vehicle, etc. • Make sure you turn off fuel-burning engine equipment when you are inside a garage or basement. Just having the doors open does not ensure your safety. • Always follow the manual directions when servicing fuel-burning equipment. • If you use a fuel-burning appliance that is approved for indoors, make sure it is vented to the outside following the manufacturer’s instructions. • Install and use exhaust fans over gas stoves. • Have a professional inspect, clean and tune up your central heating system (furnaces, flues, and chimneys) annually.
