The hexavalent chromium standards also set an action level, which is equal to one-half the permissible exposure limit (PEL), or 2.5 µg/m 3 as an 8-hour TWA. The American Conference of Governmental Industrial Hygienists (ACGIH) recommends several different Threshold Limit Values (TLVs) for chromium, chromates and other chromium compounds. exposure limit (PEL) of 5 µg/m 3 measured as Cr(VI). of .0002 mg/m3 for inhalable hexavalent chromium compounds [Cr(VI)], as well as a Short-Term Exposure Limit (STEL) of .0005 mg/m3, inhalable hexavalent chromium compounds, has been established.
