Carbon Monoxide Detectors Failing to Alert Users of Deadly Gas

Two brands of carbon monoxide detectors, GLBSUNION and CUZMAK, are failing to alert users when carbon monoxide is present, according to the U.S. Consumer Product Safety Commission. Both brands claim to detect dangerous levels of carbon monoxide and alert with a flashing red LED and a loud alarm pattern, but sensitivity tests showed they failed to alert when exposed to pre-determined concentrations of carbon monoxide. Consumers are urged not to purchase or sell these detectors, stop using them, dispose of them immediately, and install new, working detectors.
