Poisonous, Tasteless, Colorless, and Odorless Gas
Carbon monoxide (CO) is a poisonous, tasteless, colorless, and odorless gas. Formation occurs when carbon-based fuels, such as wood, propane, natural gas, oil, and kerosene, burn incompletely. If inhaled, it combines with the blood, forming carboxyhemoglobin. This reduces the oxygen-carrying capacity of the blood, and can quickly cause illness or death.

Remember, Carbon Monoxide Poisoning Can Kill You
According to the Centers for Disease Control and Prevention (CDC), unintentional CO exposure accounts for an estimated 15,000 emergency department visits and 500 unintentional deaths in the United States each year.
Do You Know the Symptoms?
Do you know the symptoms of carbon monoxide poisoning? Do you know what to do if someone displays signs of poisoning? Do you know how to identify, remedy, and prevent dangerous situations?
The symptoms of CO poisoning include nausea, headache, vomiting, drowsiness, weakness, chest pain, difficulty breathing, and confusion. Sometimes dismissed as the flu, anyone experiencing these indications should immediately consider carbon monoxide as the culprit. If the levels are high, death can occur within minutes.
If you or someone you are with displays signs of carbon monoxide poisoning, get into fresh air immediately and call for emergency medical help. Try to be ready to answer questions, such as the suspected cause of poisoning, symptoms, and signs of impairment.
Carbon Monoxide and Your Vehicle
Carbon monoxide is an ever-present danger in your vehicle. Leaky exhaust systems can allow the gas to enter through a hole in the floor, an open window, or a leaky door seal. Regular inspection and maintenance of your vehicle are crucial. Driving an SUV or station wagon with the tailgate or hatch open can draw CO into the vehicle; ensure proper ventilation through windows and vents if you must operate your vehicle in this manner.
Leave the window partially open when starting the engine, while driving the vehicle or when idling the engine while parked. Never keep the engine running when parked in your garage.
There is a myth that carbon monoxide is heavier than air. Actually, carbon monoxide is slightly lighter than air and diffuses evenly throughout a room. Another common misconception is that you will smell it before it causes harm. While you may be able to smell gas, such as propane, or smoke from a wood stove or furnace, you cannot smell carbon monoxide.
Are Your Home, Cottage, Camper, and Vehicle Safe?
A large number of appliances create carbon monoxide. Included are wood, propane, and gas fireplaces; combustion engines in vehicles, small engines such as those in lawnmowers and leaf blowers; gas and charcoal barbecues; gas kitchen ranges and water heaters; oil and gas furnaces and boilers; and portable camp stoves and lanterns.
Carbon monoxide poisoning occurs due to many possible conditions. A leaking combustion chamber in a forced-air furnace could circulate carbon monoxide through your house via the warm air vents in each room. Faulty or blocked combustion appliance vents and chimneys are dangerous. Poorly adjusted gas kitchen ranges, refrigerators and clothes dryers produce CO. An open or leaky door to an attached garage can allow exhaust from an idling vehicle to seep into your home.
During power outages, people have died while barbecuing in enclosed areas. Running a vehicle or generator in a closed garage or basement can be deadly. Operating a generator outdoors close to a window or door can result in carbon monoxide entering your home. Cooking with a portable gas stove or operating a gas lantern in your home, cabin, tent, or camper is another source of CO poisoning.
Consider every piece of combustion equipment, both inside and outside your home, cottage, and camper, as a source of poisonous carbon monoxide. Proper inspection and maintenance are necessary measures to ensure your safety. Have your equipment serviced regularly by a certified technician and have your chimneys cleaned. Another option is to replace your existing combustion equipment with non-combustion devices, such as heat pumps, electric fireplaces, and electric kitchen ranges and refrigerators.
Carbon Monoxide Detectors
The installation of carbon monoxide detectors is an essential step to prevent poisoning. According to the guidelines of the National Fire Protection Association (NFPA 720, 2005 edition), all CO alarms “shall be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms,” and each alarm “shall be located on the wall, ceiling or other location as specified in the installation instructions that accompany the unit.” Be sure to replace batteries on a regular basis, ideally every six months.
Remember that many unnecessary deaths occur each year due to carbon monoxide poisoning. Be safe! Install carbon monoxide detectors in your home, workshop, garage, cabin, and camper. Have your heating equipment and other combustion devices and appliances checked regularly by a qualified technician.
Take your vehicle to a mechanic on a regular basis to check for exhaust leaks. Consider replacing your oil, wood, and gas heating equipment with a heat pump. Think about replacing all other carbon-monoxide-producing equipment such as gas refrigerators, kitchen ranges, and clothes dryers with electric units.
With close attention and minimal effort on your part, a potentially deadly mishap can be avoided. Don’t be a statistic!
