Identification of potential sources of arsenic exposure during scrapyard work at a former uranium enrichment facility.
J Occup Environ Hyg 2004 Sep; 1(9):D96-D100
In 2002, the National Institute for Occupational Safety and Health (NIOSH) received a request for a Health Hazard Evaluation from union workers and management of a former uranium enrichment facility in Ohio, one of two in the United States operated by a nongovernment contractor and subcontractors.(1,2) Work had recently begun on dismantling the components of the gaseous diffusion process cascade, and during that process, employees and management detected a previously unknown inorganic arsenic (As) contamination.(3) Further investigation found that not only was the entire work area contaminated but that arsenic was present on the inner surfaces of the workers' respirators and in their urine. This case study describes how the NIOSH investigator and the contractor identified the source of that contamination and the recommendations that were made to reduce worker exposure.
