This large (33MB) PowerPoint is a followup to a webinar presentation in 2014 by Mark Hoover and Charles Geraci from NIOSH and Bruce Lippy from CPWR to the Labor Division of the National Safety Council. This 2015 presentation was given in person by Bruce Lippy at the NSC Labor Division meeting in Charlotte, NC on April 21, 2015. The materials were revised by Mark Hoover and Bruce Lippy to focus on nano-enabled products that the unions attending the training may encounter. These unions included the International Brotherhood of Electrical Workers, the United Auto Workers, the United Steel Workers, the International Association of Machinists and Aerospace Workers, and the Teamsters. The training included a hands-on exercise reviewing Safety Data Sheets for nano-enabled products.
