ACGIH Biological Exposure Indices

The ACGIH Biological Exposure Indices (BEIs) are guidelines developed by the American Conference of Governmental and Industrial Hygienists. They provide recommended measurement limits for specific chemicals in biological samples, like blood or urine, to assess exposure levels in workers. These indices help ensure that exposure remains within safe limits to protect health. By comparing the levels of chemicals in a worker’s body to the BEIs, employers and health professionals can evaluate if additional safety measures are needed to prevent harmful effects from exposure to hazardous substances in the workplace.
