The majority of chemical substances in commerce have no established occupational exposure limits (OELs). In the absence of established OELs, employers and workers often lack the necessary guidance on the extent to which occupational exposures should be controlled. A strategy to control occupational exposures that may have value when there are no relevant OELs is known as control banding (CB). CB is a qualitative strategy for assessing and managing hazards associated with chemical exposures in the workplace. The question about the utility of the CB strategy for workplaces in the United States has been raised, warranting a critical review of its concepts and applications. This report is the result of a review of the published literature and related proceedings on CB.
