The best method of detection is to use a carbon monoxide detector indoors. A carbon monoxide detector is like a smoke alarm. It monitors the air for carbon monoxide and sounds an alarm if a specific level is detected. Ideally, you should have at least one detector adjacent to every living area, centrally located, or on each floor in your home. Carbon monoxide detectors are best when used in combination with a service plan. Call 289-201-2226 for more information about purchasing a carbon monoxide detector.
