ACGIH® has released its 2016 editions of the TLVs® and BEIs® book and the Guide to Occupational Exposure Values.

The information in the user-friendly, pocket-sized TLVs® and BEIs® book is used worldwide as a guide for evaluation and control of workplace exposures to chemical substances and physical agents. Threshold Limit Value (TLV®) occupational exposure guidelines are recommended for more than 700 chemical substances and physical agents. There are more than 50 Biological Exposure Indices (BEIs®) that cover more than 80 chemical substances. Chemical Abstract Service (CAS) registry numbers are listed for each chemical. Introductions to each section and appendices provide philosophical bases and practical recommendations for using TLVs® and BEIs®.

The Guide to Occupational Exposure Values is a companion document to the ACGIH® TLVs® and BEIs® book and serves as a readily accessible reference for comparison of the most recently published values: 2016 Chemical Substance TLVs® from ACGIH®; AIHA/OARS Workplace Environmental Exposure Limits (WEELs); the OSHA Final Rule PELs; RELs from NIOSH; MAKs from the German Commission for the Investigation of Health Hazards of Chemical Compounds in the Workplace; and carcinogenicity designations from ACGIH®, OSHA, NIOSH, MAK, IARC, U.S. NTP, and U.S. EPA. The Guide also includes a CAS number index.
