Setting the system alarm at 50 is not recommended, unless the workplace concentration is always teetering just below this level, and compliance with the 50 ppm standard is truly an issue.Although OSHA does not define a STEL or ceiling value for CO, NIOSH does, and it is 200 ppm. Absent the condition of meeting the 50 ppm standard, a more prudent course would be to set alarm-1 (the warning alarm level) at 100 ppm and alarm-2 (the danger alarm level) at 2...See more on gasdetection.comToxic gas exposure limits and alarm levels - Crowcon ...
