What is an ACGIH® Webinar?

ACGIH® is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning opportunities. This series will consist of five 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. This ACGIH® webinar is approximately 2½ hours in duration and consists of a live presentation given via the internet with an audio telephone link similar to that of a conference call.

Audio Option

ACGIH® is pleased to offer webinar attendees an audio option. U.S. and Canadian attendees can connect to the audio portion of the webinar via the toll-free audio telephone link or listen to the audio portion through an audio stream directly through their computer. Other international participants can listen via the audio stream without incurring additional telephone charges.*

*Connection from outside the U.S. and Canada will be via streaming audio only.


This webinar contains 2.5 contact hours and may be eligible for ABIH CM credit. See the ABIH website ( for CM credit criteria. This webinar may also qualify for BCSP recertification points for Certified Safety Professionals. Participants seeking confirmation of attendance for the webinar from ACGIH® must attend the live webinar or view the archive and submit a final exam and evaluation. Certificates of Completion will be issued in a timely manner after receipt and completion of these items.
