Join Marc Hugus and Don Ewert at the American Foundry Society (AFS) EH&S Conference 2018 on October 9-11 in Warrensville Heights, Ohio. Marc and Don will be exhibiting as well as providing a presentation on October 11th at 2:15 pm titled “Respirable Crystalline Silica-Avoiding Monitoring Pitfalls and Incomplete Results“.


This engaging presentation includes information on frequent sampling errors that occur and how to do it right the first time. Learn to select work task exposure groups, the need for calibrating equipment, and how to get representative samples from an ever-changing environment. You’ll be provided strategies to reduce or fully abate penalties that OSHA may propose by challenging the science behind unfavorable test results. Participants will leave with a portfolio of pitfalls to avoid and an understanding of how sample collection practices influence the analytical results they receive from the lab.
