Fibers-tiny, synthetic fibers with near magical qualities-comprise a diversity of materials that have become profuse and nearly inextricably woven into the patterns of our lives today. "Clothing, carpet, ceiling tiles and building materials," says Ralph Zumwalde of NIOSH, Cincinnati, "all of these products are composed in some part of synthetic fibers." Zumwalde led a roundtable discussion on Synthetic Fibers in the Workplace: Where Less Fiber is Healthier at AIHCE 2000 in Orlando on May 23. Fibers have long held an interest for occupational safety and health practitioners, the most controversial case in point being the asbestos legacy. Judging from the focus and discussion of the roundtable, participants and audience members were aware of the history with asbestos fibers and eager to draw from this experience in addressing issues with newer and different synthetic fibers.
