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.
