Health hazard evaluation report HETA 96-0266-2702, Cooper Engineered Products, Bowling Green, Ohio.
On September 13, 1996, the National Institute for Occupational Safety and Health (NIOSH) received a management request for a health hazard evaluation (HHE) at Cooper Engineered Products, in Bowling Green, Ohio. The request noted concerns about workers' exposure to a new, two-component, water-based polyurethane paint (water-based polyurethane paint with polytetrafluoroethylene and a polyfunctional aziridine cross-linker) that is applied to automotive/truck rubber seals (vehicle sealing) on the dual durometer (DD) extrusion lines. Health effects described in the request included skin and upper respiratory problems. On October 16, 1996, NIOSH industrial hygienists conducted an initial site visit. Area air samples were collected on thermal desorption (TD) tube media to qualitatively identify volatile organic compounds (VOC). Bulk samples of the water-based polyurethane paint were also collected. A follow-up site visit was conducted on March 25-26, 1997, to collect additional air samples. On January 21, 1997, NIOSH medical officers conducted a site visit and questionnaire survey. In April and May 1997, skin patch testing was performed to identify employees with allergic-contact dermatitis.
