ACGIH® Presents Control Banding: Uses and Misuses Webinar



Cincinnati, Ohio — November 27, 2007 — ACGIH® presents Control Banding: Uses and Misuses webinar, scheduled for February 12, 2008 at the following times:

2:00 p.m. – 4:30 p.m. (Eastern Time)
1:00 p.m. – 3:30 p.m. (Central Time)
12:00 p.m. – 2:30 p.m. (Mountain Time)
11:00 a.m. – 1:30 p.m. (Pacific Time)

Control Banding describes a user-friendly qualitative assessment process that allows the user to quickly determine appropriate engineering controls required to protect workers based on readily available information on chemical hazards and potential for exposure. This process is intended for small and medium sized enterprises, but large corporations are also considering its application. This webinar will present and critique the version of Control Banding promoted by the United Kingdom Health and Safety Executive (HSE) and the International Labour Organization (ILO) and provides information on the Control Banding system used in the pharmaceutical industry.

Control Banding should be viewed as an "expert system." As such, it will be broken into its component parts – Hazard Group Prediction Model, Exposure Limit Prediction Model, Exposure Prediction Model, and predefined control strategies. Each component will be described and critiqued. Additionally, diacetyl, an artificial butter flavoring ingredient with no exposure limit, will be used as an example to illustrate how Control Banding is applied, and to demonstrate both its strengths and weaknesses. For example, varying information on the health hazards (e.g., the assigned risk-phases) and/or exposure assumptions can make significant differences in the final decision to improve or not improve controls. Specific recommendations on using and applying Control Banding will be presented to improve the effectiveness of the existing Control Banding scheme, including the need to perform verification studies.

After participating in this webinar, attendees will be better able to:

  • Describe the general application of Control Banding.
  • List and describe each of the four components of the Control Banding "expert system."
  • Describe the major strengths and weaknesses of each component of the "expert system."
  • Recognize opportunities to enhance Control Banding schemes leading to improvements in accuracy.
  • Understand how Control Banding may be applied as a "first pass" or triage tool to help prioritize exposure and why it should not be used as the "only" exposure assessment tool.
  • Understand the importance of performing verification studies of the effectiveness of Control Banding exposure control recommendations.

ACGIH® is pleased to offer webinar attendees a new audio option. U.S. and Canadian attendees can connect to the audio portion of the webinar via the toll-free audio telephone link or listen to the audio portion through an audio stream directly to their computer. Other international participants can listen via the audio stream without incurring additional telephone charges.

Previously, he worked for 25 years as an industrial hygienist for NIOSH, in the Division of Respirable Disease Studies, where he specialized in the measurement of pneumoconiosis producing dusts. Dr. Hewett received his PhD in industrial hygiene from the University of Pittsburgh, School of Public Health in 1991 and is certified by the American Board of Industrial Hygiene. He is the author of numerous articles and chapters on exposure assessment and statistics for industrial hygienists, as well as past chair of the AIHA Exposure Assessment Strategies Committee.

Bruce D. Naumann, PhD, DABT is a Senior Principal Scientist and Director of Occupational and Environmental Toxicology at Merck & Co., Inc. Dr. Naumann provides leadership and technical guidance to the Company on a broad range of occupational and environmental toxicology issues. He also serves as Secretary of Merck's Industrial Toxicology Advisory Committee and directs a research program focused on improving the use of science in risk assessment. Dr. Naumann received his PhD from New York University and is certified by the American Board of Toxicology. He has over 20 years of experience as an occupational toxicologist within the pharmaceutical industry. In addition to his professional responsibilities, he is a member of the ACGIH® Threshold Limit Values for Chemical Substances (TLV®-CS) Committee and the AIHA WEEL Committee.

Mark R. Stenzel, CIH is President of Exposure Assessment Applications, LLC, a consulting company that specializes in exposure and risk assessments. Prior to forming his own company, he worked for 29 years in the chemical industry where he managed all aspects of a comprehensive industrial hygiene program. He has written five peer-reviewed articles on exposure assessment, was a contributing author to the AIHA A Strategy for Assessing and Managing Occupational Exposures, 3rd edition (2006), and has made more than 25 formal presentations at technical conferences and symposia. Mr. Stenzel serves on the ACGIH® Board of Directors and is an active member of the AIHA Exposure Assessment Strategies and Occupational Epidemiology technical committees.

Paul F. Wambach, CIH has worked for the United States Department of Energy at the headquarters offices since 1980 on assignments ranging from policy development and oversight to health studies. One of his current projects is the Beryllium-Associated Worker Registry, which collects, analyzes and reports health and exposure data created through the operation of Department of Energy chronic beryllium disease (CBD) prevention programs. Mr. Wambach has over 30 years of experience in the comprehensive practice of industrial hygiene.

This webinar is pending approval by the American Board of Industrial Hygiene (ABIH) for .5 ABIH (IH) Certification Maintenance (CM) Point. This webinar qualifies for .15 BCSP (SP) Continuance of Certification (COC) Point for Certified Safety Professionals. Participants seeking CM or COC points must attend the live webinar or view the archive and submit a final exam and evaluation.
