The membership of the YPSW Section has included many of the Founders and Developers of the modern IH profession, OSHA Directors, AIHA Presidents, Directors of Health and Safety for Major Corporations, and many others who helped advance the science as we know it today and surely beyond as time goes by.

The YPSW is indeed a "special" section owing to our incredible past, current, and future members.
