Large Recall of CO Sensors Under Way
Several instrument manufacturers have posted warnings of an industry-wide recall of 4CF carbon monoxide sensors made by City Technology, a British company that is owned by Honeywell. The U.S. Mine Safety and Health Administration posted Industrial Scientific's alert on its own site last Friday; there is still no notice posted on the City Technology Web site (www.citytech.com), and an email sent Friday to its address for technical assistance has not been answered.
The recall affects about 80,000 sensors for the industrial market that were shipped between May 2007 and May 2008 with serial numbers in the range of 10199194 through 12844839, according to the Industrial Scientific recall notice, which says 16,450 sensors shipped to Industrial Scientific are affected. 3M's advisory notice, dated July 10, does not specify how many of the affected sensors were shipped to 3M, but it lists five series of 3M detectors and replacement sensors (110 Series, 740 Series, 950 Series, 600 Series, and Alien Series) made between June 1, 2007, and July 2, 2008, that are included in the recall. Other manufacturers also posted advisories telling customers how they could obtain replacements.
3M's notice asks customers to arrange for a free replacement CO sensor/product by contacting the 3M Customer Care Center at 800-328-1667 and saying you are calling about the "CO sensor product recall." Industrial Scientific also replaces affected sensors at no charge and directs customers to contact its local customer service centers or call 800-338-3287.
