Can CO be detected? Yes, CO can be detected with CO detectors that meet the requirements of Underwriters Laboratories (UL) standard 2034 (1998 revision).
Since the toxic effect of CO is dependent upon both CO concentration and length of exposure, long-term exposure to a low concentration can produce effects similar to short term exposure to a high concentration.
Detectors that meet the UL standard measure both high CO concentrations over short periods of time and low CO concentrations over long periods of time. The effects of CO can be cumulative over time.
Detectors sound an alarm before the level of CO in a person's blood would become crippling.
Detectors that meet the UL 2034 standard currently cost between $35 and $80.
