The American Conference of Governmental Industrial Hygienists (ACGIH) last week ratified the 2002 Threshold Limit Values (TLVs) for chemical substances and physical agents and Biological Exposure Indices (BEIs). The organization's Board of Directors also approved recommendations for additions to the Notice of Intended Change (NIC).
A complete listing of the substances that were acted upon is located on the ACGIH Web site, at www.acgih.org. Draft documentation for the substances on the NIC are currently available for purchase from the ACGIH.
