NIOSH Testimony on Polychlorinated Biphenyls; Exclusions, Exemptions and Use Authorization by R. A. Lemen, September 4, 1987.
This testimony concerns the proposed rule from the Environmental Protection Agency on polychlorinated biphenyls; exclusions, exemptions and use authorizations. NIOSH recommends that polychlorinated biphenyls (PCBs) be regarded as potential human carcinogens and that worker exposure to PCBs be controlled to the lowest feasible limit. Measures for controlling exposure to PCBs include good work practices, routine monitoring for PCBs, use of protective equipment, and worker training. NIOSH believes that the use of protective gloves should be required when handling materials potentially contaminated with PCBs. NIOSH also believes that in addition to Viton, other effective and less expensive glove materials such as butyl, neoprene, Saranex Tyvek, nitrile, Viton-SF, and Teflon should be permitted to help control dermal exposure to slightly contaminated fluids. Two other concerns are also noted: concern for PCB contamination of investment casting waxes, and concern for decomposition products of incomplete combustion of PCBs to polychlorinated dibenzofurans.
