Maximum allowable 8-hours work place exposure, (OSHA). The 8-hour PEL for CO in maritime operations is also 50 ppm. Maritime workers, however, must be removed from exposure if the CO concentration in the atmosphere exceeds 100 ppm. The peak CO level for employees engaged in roll-on roll-off operations during cargo loading and unloading is 200 ppm. ASHRAE Carbon Monoxide Exposure Limits 0-0.5 = level of CO in clean fresh outdoor air, such as far out at sea or in remote wilderness. 0.1-1 = level of increases in average outdoor CO–within current outdoor ranges of 0-5 ppm– that are associated in over 100 epidemiological studies with significantly increased risks of mortality and morbidity from many cardiovascular and respiratory disorders and, in growing fetuses, with low Healthy adults will have headaches within 1-2 hours.
