Beryllium: Hazards evaluation, facility classification, consequence analysis of releases during potential accidents, and protection of public and workers

The American Conference of Government Industrial Hygienists (ACGIH)5 and Occupational Safety and Health Administration (OSHA) adopted exposure threshold limit value for workers at 2.0 μg/m3, based on 8-hr TWA. However, 10 CFR 850 Rule on CBD and Prevention Program6 requires a protection at 0.2 μg/m3 (8 h TWA), to further mitigate or prevent any health effects or CBD. Thus, 40 CFR 61.32, ACGIH and OSHA guide, and 10 CFR 850 Rule, coupled with the worker protection program and adequate safety controls, provide adequate protection from the CBD to the workers and public.
