Tim Ryan, associate professor in the School of Public Health Sciences and Professions, and student researcher Kate Stone, are studying the effectiveness of carbon monoxide detectors – and coming up with some concerning results. The small-scale study has produced a 35 percent failure rate among carbon monoxide detectors tested - all in use. Nine out of 26 detectors failed completely. Several others failed “safely,” in which the detectors’ sensors engaged too early when exposed to carbon monoxide, Ryan said. "Some of the detectors in the study indicated that they were working properly even if they were not," he added. Stone, a senior with double majors in industrial hygiene and environmental health, tests each detector by placing them in an exposure chamber with carbon monoxide at three different concentrations in order to observe whether the unit’s sensor alarms at the correct time. The alarms used in the study were borrowed from local residents in the Athens, Ohio, area who were provided a replacement while theirs were in use. Most of the detectors provided were more than 10 years old. Stone hopes to test a total of 50 detectors before ending the study this spring. In the United States, more than 400 people die each year from accidental carbon monoxide poisoning, according to the U.S. Centers for Disease Control and Prevention. Carbon monoxide often goes unnoticed because of its odorless and colorless nature, making it difficult for homeowners to know whether their carbon monoxide detectors are working correctly.
