1:30 p.m. - 2:15 p.m. 

Globally-Endorsed Occupational Hygiene Training – Proof of Concept for Industry, Academia, and Philanthropy

Presenter: Nancy McClellan, MPH, CIH, CHMM, Global Industrial Hygiene Manager for Lafarge Holcim, AIHA Board of Directors, OHTA Board of Directors Co-Chair, Barrington, IL; Albert Tien, PhD, ScD, Managing Partner at 2TSustainAbility LLC, President-elect, Workplace Health without Borders-US, Chagrin Falls, OH.

A review of the objectives of various nonprofit organizations based in the USA or Canada indicate the need to build up industrial hygiene awareness and capacity in developing countries. Approaches have included directing foreign students and professionals to enroll in university programs which provide accepted curricula in industrial hygiene, professional mentorship programs, or having industrial hygienists provide lectures or training abroad.  Corporate social responsibility requirements from lender organizations or rating firms and evolving local and global health and safety legislation, influenced by US or EU regulations, have influenced multinational companies to identify or develop local resources which can provide industrial hygiene services. 

The evolution of the Occupational Hygiene Training Association (OHTA) and the training scheme has provided a globally piloted and endorsed program for industrial hygiene training at the awareness and technologist levels.  As the program has grown, multiple sectors including industry, academia and philanthropic efforts have successfully developed and implemented both levels of training. The next phase of growth for OHTA will include expansion to a larger market as it better communicates the program's capabilities to a world in desperate need for occupational/industrial hygiene resources.

2:15 p.m. - 3:00 p.m. 

Assessing Chemical Hazards in the Workplace: The NIOSH Occupational Exposure Banding Process

Presenter: Thomas Lentz, Chief, Document Development Branch, NIOSH, Cincinnati, OH. 

In March 2017, NIOSH a​​nnounced the availability of a draft Current Intelligence Bulletin entitled The NIOSH Occupational Exposure Banding Process: Guidance for the Evaluation of Chemical Hazards for public comment. This new guidance addresses an important need for chemical hazard assessment to protect workers from workplace chemicals without occupational exposure limits (OELs). Specifically, the draft occupational exposure banding process is a method for assigning chemicals into specific categories called Occupational Exposure Bands (OEBs). These bands are assigned based on a chemical’s toxicological potency and the adverse health effects associated with exposure. OEBs range from band A to band E, with each band corresponding to a range of exposure concentrations that is expected to protect worker health. The guidance is intended to apply occupational exposure banding to a broader spectrum of chemicals used in occupational settings. The accuracy and reliability of the OEBs have been validated using multiple phases of evaluation of the occupational exposure banding process. An e-Tool will also accompany the draft guidance as a resource for assigning chemicals to OEBs.

Given the reality that the rate at which chemicals are introduced into commerce outpaces the development of authoritative OELs, occupational exposure banding provides a practical approach for chemical assessment to inform risk management decisions. Details about the process and use of the e-Tool will be described to provide the audience with practical guidance for assessing chemical hazards in the workplace. Efforts to disseminate the guidance and assess its utility through stakeholder engagement in public review and feedback will also be described.​​​​​​​​​​

Dr. Albert J. Tien has over 25 years of experience within the USA and internationally dealing with environmental and occupational health issues such as source and spread of Yersinia enterocolitica and related species as a causative agent of gastroenteritis; Indoor Air Quality issues caused by adhesives, paints and fungi; biodegradation of TCE and other VOC under aerobic and anerobic conditions; identification of sources of hexavalent chromium in the cement manufacturing process; exposure scenario and mitigation of potential health risks from waste derived fuels used in the cement industry; identification and elimination of asbestos and other friable minerals in cement plants and rock crushing facilities; identification and mitigation of respirable and nuisance dusts in the waste fuel processing facilities; use of respirometry and lung function studies to monitor the long-term effects of exposure to Portland cement dust on a cohort of 4000 cement workers across Europe and Turkey; and identification and mitigation of respirable crystalline silica through application of good practices. Dr. Albert Tien holds a BS in Biological Chemistry from Tulane University, MS in Life Sciences from New Mexico Highlands University, PhD in Environmental Microbiology/Biotechnology from the Swiss Federal Institute of Technology Zurich, Post-doctoral studies at the Oakridge Institute for Science and Engineering, and Business studies at St. Gallen University and the International Institute for Management Development (IMD) in Lausanne. Presently he is the Managing Partner at 2TSustainAbility LLC, as well as serving as the President-elect for the non-profit organization Workplace Health Without Borders-US.​

Nancy McClellan, MPH, CIH, CHMM, Group/Global Industrial Hygiene Manager for LafargeHolcim, AIHA Board of Directors, OHTA Board of Directors Co-Chair, Barrington, IL.

Prior to joining LafargeHolcim, the world’s largest building materials corporation as the global industrial hygiene manager, Nancy McClellan worked for AbbVie pharmaceutical in the same capacity for almost 6 years. She has invested over 25 years in practicing occupational hygiene in a wide variety of high hazard industries. As a self-employed consultant for 15 years she provided services to industries such as the automotive, military, hospital, electronic, food, pharmaceutical, chemical, and housing industries. She has also provided legal expert witnessing for nationally-profiled, catastrophic incidents.

In her volunteer professional life, Ms. McClellan currently serves on the Board of Directors for both the American Industrial Hygiene Association and the globally recognized Occupational Hygiene Training Association. She has also served as a past Director and committee chair for the American Board of Industrial Hygiene Board of Directors and she continued to represent ABIH as the Chair of the Joint Occupational Hygiene Ethics Education Committee after completing her term in 2010. She is an active member of the British and Irish Occupational Hygiene Societies as a conference speaker and organizational liaison.​

Thomas J. Lentz, Chief, Document Development Branch, National Institute for Occupational Safety and Health, Cincinnati, OH.

T.J. Lentz is a lead health scientist/research occupational hygienist and Chief of the Document Development Branch with NIOSH. Dr. Lentz conducts research to evaluate occupational and environmental hazards, with projects and interests that include: investigation of small business industries and their hazards; assessment of safety hazards in construction trades; and evaluation of toxicology and epidemiology data on chemical and physical agents to determine health risks and appropriate prevention strategies. Dr. Lentz is particularly interested in studying how design, planning, and control engineering can be used to address safety and health challenges in the work environment. Major duties include developing informational materials and guidance for other agencies, industry, labor groups, and the public. Dr. Lentz previously served as the Policy Response Coordinator for the Institute. Dr. Lentz earned a BA in Biology/Philosophy from Wittenberg University, an MPH in Environmental Health Sciences/Health Policy from Yale University, and a PhD in Environmental Health/Industrial Hygiene from the University of Cincinnati.​
