It is totally undetectable to human senses. Because carbon monoxide (CO) is a colorless, odorless and tasteless chemical compound, it is virtually impossible for humans to detect its presence.
It is highly toxic. CO enters the blood stream and replaces the body's oxygen.
CO poisoning has many symptoms. It takes several hours for CO to exit the body, so even low concentrations can gradually build up in the blood, causing dizziness, headaches, nausea and other flu-like symptoms. In high concentrations, it acts very quickly.
Excessive buildup of CO can lead to coma and death.
It is the leading cause of accidental poisoning in America. Each year, hundreds of people are killed and thousands more are injured as a result of CO exposure. In fact, CO causes more accidental poisonings in the U.S. than any other chemical substance.
Poor ventilation is often a major factor in carbon monoxide poisoning. During cold weather, when doors and windows tend to be closed, decreased ventilation allows CO to accumulate.
Sources of Carbon Monoxide
Carbon monoxide results from incomplete combustion of carbon-based or fossil fuels, such as kerosene, natural gas, gasoline, propane, butane, etc. Organic substances, such as wood, paper and cigarettes, are also carbon-based fuels. Basically, anything burned for heat or used to power an engine can release CO.
The less efficiently any carbon-based or fossil fuels are burned, the more CO is released during the burning process. That's why regular maintenance of anything that burns carbon-based fuels can significantly reduce your chances of being exposed to dangerous amounts of CO in your home or business.
Operating any gas-powered motor indoors or in an attached garage, even if the garage door is open, can quickly cause a CO buildup in the home and pose a serious threat.
To prevent the buildup of CO in your home, follow these steps:
Have a qualified contractor annually check your heating appliances, vents and chimneys to be sure they are functioning properly and venting correctly to the outside. Keep vents and chimneys clear of debris, such as leaves or snow.
Do not use your dryer, stove or oven as a heating source.
Never operate motor vehicles, charcoal or portable gas grills or motorized equipment in enclosed spaces, such as garages or carports, even if the door is open.
Never operate grills inside garages, tents, trailers or other enclosed spaces.
