NEW! Computational Fluid Dynamics (CFD) for Industrial Ventilation Online Course

10% Off Now through September 15th!

20 Education Contact Hours

ACGIH’s Computational Fluid Dynamics (CFD) for Industrial Ventilation Course will be presented entirely online through a combination of webinars and independent study. Course instruction offers how to interpret the results of a CFD analysis along with understanding how to use subsequent metrics to identify and improve the functionality of ventilation systems.

Starting this October, there will be six live sessions (synchronous classes) led by instructors who will promote vigorous debate and guide actual case evaluations. Additionally, the modules provide video lectures (asynchronous classes) with step-by-step instructions for how to perform a simulation, as well as dynamic discussions on how to interpret CFD results. All live sessions will be made available on-demand after they are presented.

COVID-19 Aerosol Exposures in the Workplace Webinar Series: Tying it All Together



ACGIH® is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning webinars. A webinar, short for Web-based seminar, is a presentation, lecture, or seminar that is transmitted over the Internet. A key feature of a webinar is its interactive elements — the ability to give, receive and discuss information. Webinars are as effective as on-site presentations without the travel expense. An ACGIH webinar can be of various durations and consists of a live presentation given via the Internet with an audio telephone link similar to that of a conference call.

Each webinar may qualify for ABIH CM credit and BSCP Continuance of Certification points. To receive confirmation of attendance, attendees must view the webinar and submit a final exam and evaluation. Each webinar includes one test. Additional tests can be purchased for other attendees.
