The Dupps Company of Germantown, Ohio was recently named the winner of the 2015 Rusty Demeules Award for Safety Excellence. The award is presented by the Fabricators and Manufacturers Association (FMA), sponsored by CNA Insurance Companies, and created by FMA's Safety Council to recognize a company with a demonstrated safety culture.
