ACGIH® BOARD RATIFIES 2001 TLVs® and BEIs®
Cincinnati, Ohio - February 1, 2001 - ACGIH® Worldwide announced today that its Board of Directors
ratified the 2001 Threshold Limit Values (TLVs®) for Chemical Substances and Physical Agents and
Biological Exposure Indices (BEIs®). The Board also approved recommendations for additions to the
Notices of Intended Changes (NIC).
A listing of the substances and agents that were acted upon is attached. The complete report for all three
Committees (BEI®, Chemical Substances TLV®, and Physical Agents TLV®) was published in the January
issue of the ACGIH® newsletter Today!. The TLV® /BEI® Book can be purchased online at www.acgih.org/store. Ratifications include; retention of Sodium Sesquicarbonate (Trona) on the NIC until at least next year, and the adoption of TLVs® for Refractory Ceramic Fibers (RCF) and Hand Activity Level
(HAL). Trona had been published in Issues Under Study since 1990, and was added to the NIC in 1999.
RCF had been on the NIC since 1996. HAL was added to the NIC in 2000.
The HAL-TLV® is based on epidemiological, psychophysical, and biomechanical studies and is
applied to "mono-task" jobs performed for four hours or more per day. Exposures are characterized in
terms of average hand activity level and peak hand force. ACGIH® has posted the HAL-TLV®
Documentation on its website in January 2001. For a limited time, visitors to the site (www.acgih.org) will
have the opportunity to download the Documentation FREE. Thereafter, the Documentation, along with
all other TLV® and BEI® Documentations will be available for purchase online at www.acgih.org/store.
With the adoption of the HAL-TLV® comes the challenge of assisting occupational health and safety
professionals with the necessary training and education. According to Kristin Száva, Education Director
for ACGIH®, "we are planning to offer continuing education programs relative to Hand Activity Level, and
other issues regarding ergonomics. As the developer of the HAL-TLV®, ACGIH® will provide integrity
to the program that cannot be found elsewhere." Those interested in more information on these and other
education related programs, submit your request at http://www.acgih.org/contact/contactconffrm.htm.
The 2001 TLV®/BEI® Book will also feature a new section on Bioaerosols. ACGIH® also recommends
purchasing the companion to the TLV®/BEI® Book - The Guide to Occupational Exposure Values - 2001.
The 2001 TLV®/BEI® Book is FREE to ACGIH® members and is $26.95 for non-members. The
Guide to Occupational Exposure Values - 2001 is $49.95. Quantity discounts are available. Those
