PDC Description:

Risk assessment is an essential tool used in the occupational hygiene profession. Occupational hygienists use risk assessment to establish internal occupational exposure limits, predict health outcomes of exposure for certain groups of workers, and deal with new and emerging hazardous compounds. Occupational and environmental health experts should be aware of the most up-to-date risk assessment techniques, so they can take advantage of these methods as part of their professional expertise. This PDC will take participants for an intensive one-day ride exploring how and when they can use risk assessment methods.

The objective of the class is to demonstrate different methods and approaches used for risk assessment purposes. Structural components of the risk assessment paradigm (hazard identification, exposure assessment, dose-response assessment, and risk characterization) will be described from a practical point of view. The participants will learn through class exercises how to obtain and interpret risk metrics, including: absolute and relative risk, attributable risk fraction, unit risk, slope factor, reference concentration and dose, and other metrics. The audience will participate in exciting and interactive exercises, including a statistical risk simulation demonstrating the probabilistic nature of hazards and health outcomes. “Risk taking behavior” characteristics of the audience will be tested and analyzed: a method that can be useful for individual risk assessment at workplaces. The class will be based on case studies which are intended to refresh the audience’s knowledge on numerous hazardous agents including, but not limited to, glyphosate, acrylamide, benzene, beryllium, cadmium, and nanoparticles. The participants also will learn methods to develop hypothetical internal standards to protect workers from adverse health effects.

Intermediate level education and experience in environmental and/or occupational health exposure assessment is required. Some risk assessment background a plus.

1. Interpret basic definitions and metrics of risk assessment.
2. Discuss 4 -steps risk assessment paradigm and its advantages.
3. Utilize statistical simulation for exposure and risk calculations.
4. Calculate absolute and relative carcinogenic risk values based on slope factors and unit risks.
5. Search for relevant risk assessment information.
6. Interpret excess risk values based on the various risk acceptability criteria.
7. Derive internal standards from available risk assessment information.
8. Communicate risk assessment procedure and its results in unified way.

Dr Bob Rajan OBE, JP is HM Principal Inspector of Health and Safety, a strategic thinker and policy developer. Many of his proposals are included in COSHH regulations, HSE guidance and international standards and publications. He has over 30 years of experience in occupational hygiene, published widely and had written books (own and contributed to chapters). He has been an examiner in occupational hygiene (BOHS and other institutions) and a peer reviewer for Annals and other journals. He is a past president of BOHS and contributed widely for the advancement of BOHS and occupational hygiene including PPE, It’s in Your Hands and the Clean Air Take care, Hon Editor BOHS Newsletter. He introduced and driving the LOcHER project. He developed the Exposure Control Indicators used by HSE. His new proposals include transformational occupational hygiene and designing adequate exposure control measures that encompass failure minimisation. Experienced n product development.

PDC Description:
To explore, learn and share new ideas on Transformational Occupational Hygiene (TOH).
My working definition of TOH is: aims to deliver effective occupational exposure risk management to hazardous agents* through vison, creativity, innovation, inspirational motivation and /influence and failure minimisation designs.

The objectives for the PDS are: (i) How to maximise OH business value demonstration and (ii) Exploring the delivery of adequate exposure control, productivity, and sustainability through designing failure minimisation approaches using a number of real-world problem solving exercises.

Attendee Experience:
A keen occupational hygienist, who is leader in the area or wishing to acquire knowledge, skills and experience to become a leader;

Who is not only interested in OH, but on productivity, sustainability, communication, utilising behavioural approaches in OH and business value delivery. A positive mind for change, embracing new approaches, thinking the unthinkable to practice transformational OH.

Learning Outcomes:
How to apply communication principles; How to think outside the box for developing new ideas including control measure; why the understanding of MINDSPACE is vital for better practice of OH; Thinking in the space of engineering designs so that OHs can work productively with engineers and suppliers. Ideas for presenting effective business report instead of pages of traditional OH reports.

PDC Description:
Indoor air quality and thermal comfort are two of the top-priority topics in occupational hygiene literature of the past years. For both topics, the recent literature reports on, as well as practical examples of, typical health hazards and measurement findings shall be presented. Further, the participants will be introduced to the most relevant measurement strategies and measurement techniques. Furthermore, several examples of indoor air quality measurements will be worked on in small-group sessions and discussion rounds. Finally, managing indoor air and thermal comfort in office workplaces will complete the course.

Attendee Experience Criteria:
