GIVEN that OSHA tried to lower its occupational limits for CO from 50ppm average over 8 hours to 35ppm (NIOSH’s recommended limit) in 1988 under Reagan but was stopped from doing so by the US Circuit Court of Appeals, which remanded the rule for reconsideration...
WHY has OSHA still not reconsidered it under Presidents Bush (41), Clinton, Bush (43) or Obama?
