Exposure monitoring is increasingly being required at lower and lower levels; examples include beryllium, silica, and carbon nanotubes. These examples are used as case studies for developing monitoring strategies at microgram levels or below. For beryllium, pending regulatory changes with both OSHA and the Department of Energy will have an impact on exposure assessment strategies used in the field and may demand significant adjustments. For example, typical laboratory analysis techniques may not be sensitive enough for short-term air samples. Data evaluation may require tailored statistical methods to properly determine whether very low exposure and surface contamination limits are being met. The changes may also affect requirements for personal protective equipment, workplace housekeeping, and how sampling results are used to implement these requirements. The seven-step Data Quality Objective process provides a logical and recognized framework for planning exposure assessment risk management decision strategies. This webinar will provide a forum on managing ultra-low level exposure monitoring issues.

Learning Objectives

Upon completion, participants will be able to:

  • Explain how trace-level occupational exposure limits can impact exposure assessment strategies, sampling, and analysis requirements
  • Discuss the Data Quality Objectives framework for risk management decision-making
  • Detail proposed new requirements for worker protection
  • Apply strategies for other ultra-trace contaminants of concern


Steven Jahn, CIH, has been a practicing industrial hygienist since 1980 and is currently a Technical Risk Specialist in the Business Operations unit of Savannah River Nuclear Solutions, LLC. Steven is a former manager of Industrial Hygiene at the Savannah River Site in Aiken, South Carolina. He has been actively engaged in the implementation of the Department of Energy 10 CFR 850 beryllium regulation and has been involved with sampling and analytical issues around surface contamination characterizations in lead, asbestos, radiological, and beryllium contaminated environments. He was chair of the AIHA Exposure Assessment Strategies Committee from 2012 to 2013 and has been actively engaged in the promotion of the values in a comprehensive approach to Exposure Assessment since 1996, culminating in leadership for editing the 4th Edition of the AIHA Strategy Book in 2015. He received an MBA from Nova Southeastern University in 1999 and has been a CIH since 1990.

Michael Brisson, M.S., PMP, is a Technical Advisor with 37 years of analytical laboratory experience. Brisson has had lead roles in nuclear and environmental laboratory projects. Brisson’s publications have focused on trace-level beryllium analysis in nuclear settings. Brisson has extensive international standards involvement as technical lead for 17 ASTM International and four ISO standards.
