Kan. Like smoke detectors, carbon monoxide detectors can save lives. Carbon monoxide results from incomplete combustion. As carbon monoxide is breathed, it replaces oxygen in the blood. The gas also can cause disorientation, a loss of consciousness, and death, Bode said. For example, gas furnaces and water heaters should be inspected by a service contractor at least once a year to make sure that the gas burner is operating correctly, and that the heat exchanger and chimney are in good condition.
Regular maintenance is recommended.
With a gas range, observe the color of the burner flame. If the flame is not blue, ask a service technician to check the burner. A gas range also should not be used to take the chill out of the air or heat the house. Vent a gas or electric clothes dryer outside the house, and check vents periodically to make sure that they remain free of lint or other debris. Reserve non-electric space heaters for emergency use.
