Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, HETA 99-0085-2736, 1999 Apr; :1-24
In January 1999, 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 maintenance workers' exposures to an acrylic polymer (Shinkolit-P-UT-100), specifically the component, n-cyclohexylmaleimide (n-CHMI). NIOSH had conducted an HHE for USPL in 1998 to look at employees' exposures to the components of UT-100, and had developed a new analytical screening method for n-CHMI.
