CO Detector Testing

Every year in the United States, 20,000 to 30,000 become ill from carbon monoxide poisoning. Because of its colorless, odorless, and tasteless qualities, CO detector testing is one of the most vital safety precautions that should be taken. In the same way that smoke detectors need to be regularly tested, it is also important to test system-connected CO detectors. Legislation governing CO detectors is changing, with many states already requiring the installation of CO detectors, and this will soon extend country wide and with it will bring new legislation on the testing of detectors.
