Abstract
In March 1998. the National Institute for Occupational Safety and Health (NIOSH) received a health hazard evaluation (HHE) request from the management at U.S. Precision Lens, Inc. (USPL) in Cincinnati, Ohio. the HHE request asked for assistance in evaluating workers' exposures to an acrylic polymer (Shinkolite-P UT-100), specifically the component n-cyclohexylmaleimide (n-CHMI). The polymer is used in the production of lenses for large screen projection television sets. In response to this request, an initial site visit was conducted on March 18, 1998, to collect bulk samples of the raw material for volatile organic compounds (VOCs) analysis and observe the production process. Additional site visits were conducted on April 14, 1998, to collect environmental air samples for n-CHMI, VOCs, methyl methacrylate (MMA), and styrene. informal employee interviews were conducted with 13 individuals involved in UT-100 production during these site visits.
