ACGIH® Presents Enzymes in the Workplace: Strategies for Minimizing Health Effects Symposium



Cincinnati, Ohio — June 9, 2004 — ACGIH® is pleased to present Enzymes in the Workplace: Strategies for Minimizing Health Effects Symposium scheduled for September 29-30, 2004 at the Hyatt Regency Cincinnati Hotel in Cincinnati, Ohio. This two-day Symposium will explore vital health effects exposure and many other issues relating to enzymes in the workplace. The Symposium will consist of plenary sessions and roundtables, and will offer an extensive technical presentation of current scientific data focusing on the numerous and complex issues of health effects resulting from enzymes exposure.

A number of enzymes derived from microorganisms have important commercial uses. Among these are a-amylase and subtilisins. These are large molecular weight proteins that can be allergenic for some people, causing adverse health effects in the upper and lower respiratory tract and the skin.

ACGIH® has placed these enzymes on its Chemical Substances and Other Issues Under Study List with a view toward revising the existing TLV® for subtilisins and creating a new TLV® for α-amylase. Through this Symposium, ACGIH® and the ACGIH® Threshold Limit Values for Chemical Substances (TLV®-CS) Committee are looking forward to receiving, reviewing, and considering data relevant to this subject matter.

It is ACGIH®'s policy to consider all relevant data in its TLV® proposals and recommendations. TLVs® are based on data available at the time that the recommendation is made and it is ACGIH®'s policy not to commit to withholding a TLV® until ongoing research is completed. However, ACGIH® recognizes that many of the substances that are covered by the TLVs® may be subjects of ongoing research. The TLVs® are not carved in stone, and may be reconsidered at any time, especially when significant new data become available.

The American Board of Industrial Hygiene (ABIH) will award 2.0 Certification Maintenance (CM) Points upon completion of this Symposium. The Board of Certified Safety Professionals (BCSP) will award 1.25 Continuance of Certification (COC) Points upon completion of this Symposium.
