January 19, 1996 Release # 96-061 WASHINGTON, D.C.- CPSC is urgently warning consumers that approximately 18,700 SC-01 carbon monoxide (CO) detectors imported and distributed by Sinostone Corporation of Wood Dale, Ill., may fail to alarm. As a result, consumers could be exposed to dangerous levels of carbon monoxide, a colorless, odorless, toxic gas, which could lead to serious injury or death. CPSC tested SC-01 detectors and found that the detectors could fail to alarm at concentrations of CO as high as 1,000 parts per million. Concentrations at this level could lead to permanent brain damage or death in as little as 35 minutes. CPSC requested that Sinostone recall the detectors, remove them from store shelves, and contact retailers and consumers about this recall. CPSC is unilaterally issuing this press release concerning Sinostone's SC-01 CO detectors because the company is unable to participate in a recall and has not warned the public about potential risks associated with the CO detectors.The rectangular, grey, plastic detectors measure approximately 5.5 inches long, 3.25 inches wide, and 1.5 inches deep, with vertical vents and the word "Accusniffer" on the front of the detector. A green "Power" light and a red "Alarm" light appear in the center of the detectors above the "Test/Reset" button. The model number, company name, and address are located on a sticker on the back of the detector. The detectors have a white cord and plug and a battery back-up system.Hardware stores and home improvement stores sold the detectors nationwide from October 1994 to August 1995 for a wholesale price of approximately $28. The detectors were packaged in a rectangular green box labeled in part, "Accusniffer...110 Volt Plug-in plus Battery Backup...SC-01, Stand alone model..."Consumers are urged to stop using Sinostone SC-01 CO detectors and replace them with new detectors that meet the October 1, 1995 requirements of Underwriters Laboratories Standard 2034.CO is produced when fu
