Introducing a program that brings professional development courses (PDCs) online! Attend high-quality IH/OEHS education outside of AIHce EXP, AIHA's premier annual conference.

Several different PDCs are being offered from November 7 through 11, so you can choose what works for your budget and schedule. Expand your knowledge in core aspects of the OEHS profession with live demonstrations, practice exercises, and group activities.

Course offerings are listed below. To register for a course, visit the course description page.

Registration will open in August!​​ Course offerings are being added below. Register for the course you want through the course's description page.

Identifying Exposures and Controls of Welding Fume as a Carcinogen

IARC has recently categorized welding fume as a Group 1 carcinogen. Welding is nearly ubiquitous in industrial environments. This PDC describes common welding and thermal cutting processes and the health and safety hazards associated with each of these processes. The terminology used in the welding industry is incorporated throughout the PDC as a means of familiarizing attendees with the vocabulary used in the workplace. Materials, thermal processes, and scenarios associated with the potential for overexposures are described. Emphasis is placed on Manganese and Hexavalent chromium exposures as well as many other health and safety hazards. Suggestions for improving the quality of monitoring data are provided as are suggestions for prioritizing exposure assessments. Ventilation techniques and respiratory protection options are also described.

Communicating Science and Technical Concepts

It can be challenging to communicate OEHS topics. This PDC will help learners become more effective communicators, both in general and specifically of scientific and technical topics with others who do not have the same background, knowledge, or expertise, whether that is other industrial hygienists, occupational environmental health and safety professionals, or those in the sci-tech or STEM fields. The science and practice of effective communication is a significant topic and part of the workshop (if we can’t communicate effectively, we certainly can’t expect to be able to communicate on sci-tech topics). Much of the morning is effective communication in general, while the afternoon we focus more on sci-tech concepts. Many of the cases, examples, stories, and exercises use IH, OEHS, sci-tech, and STEM themes and contexts. We'll explore a dozen major areas, including over 150 subtopics.

Leadership Soft Skills: Emotional Intelligence, Managing Conflict, and Communicating Effectively

This PDC expands on AIHA's three webinars on Leadership Soft Skills (Communicating Effectively, Managing Conflict, and Emotional Intelligence). This PDC will give attendees the opportunity to learn about leadership human skills as well as practice them with their colleagues in an interesting setting involving a variety of occupational hygiene situations, role-playing, and sharing work experiences. Attendees are encouraged to submit problems or questions prior to the course for discussion; submissions will be sanitized for confidentiality. While we will be focusing on the three primary skills of communicating effectively, managing conflict, and emotional intelligence, attendees will find that topics such as problem-solving, being a team player, resiliency, creative thinking, and working well under pressure will be woven into the course. This PDC will be fun-packed, memorable, and valuable.

Understanding Exposure Statistics and Variability in IH

Is a group compliant with the OEL? Are individuals within this group likely to experience higher risk than the group average? What effect does an intervention have on the underlying exposure distribution? The answers to these questions are paramount to the practice of industrial hygiene. Unfortunately, the variability observed in occupational exposure levels represents a considerable challenge to obtaining them reliably. Despite available and well-described theoretical approaches to tackle these issues, including the AIHA monograph, "A Strategy for Assessing and Managing Occupational Exposures," or in the recent European guidelines, there is a lack of practical tools to support day-to-day decision-making when analyzing exposure measurement data. Even fewer tools tackle frequent methodological issues such as the presence of non-detects or present the results in a format easy to communicate.

First available in 2015 and updated in 2018, the Expostats platform ( is a freely available web application developed at the University of Montreal, Canada, aiming to support IH practitioners in interpreting occupational exposure measurements through Bayesian statistics. This PDC presents the challenge of exposure variability and the current theory underpinning the interpretation of workplace exposure levels. It also provides a primer in Bayesian statistics and demonstrates how decision-making can be conducted using the Expostats tools.
