There are more than 38 million residential carbon monoxide detectors installed in the United States. We tested 30 detectors in use and found that more than half failed to function properly, alarming too early or too late. Forty percent of detectors failed to alarm in hazardous concentrations, despite outward indications that they were operating as intended. Public health professionals should consider community education concerning detector use and should work with stakeholders to improve the reliability and accuracy of these devices.
美国安装了超过 3800 万台住宅用一氧化碳探测器。我们测试了 30 台正在使用的探测器，发现超过一半的探测器无法正常工作，报警过早或过晚。尽管从外观上看这些探测器的工作状态符合预期，但仍有 40%的探测器未能在危险浓度下报警。公共卫生专业人员应考虑开展有关探测器使用的社区教育，并与利益相关者合作，提高这些设备的可靠性和准确性。
