Abstract
Occupational exposures to cured resin particulates, styrene (100425) monomer, and ergonomic stresses at Armco Composites (SIC-3079), Hartford City, Indiana were investigated. About 120 production employees work on site. The study was a result of a confidential request and was performed on March 1 and 12, and July 20 and 21, 1981. Air samples were analyzed and medical interviews were conducted with 29 workers and an ergonomic study was performed. Personal breathing zone time weighted average concentrations of cured resin particulates peaked at 20.1 milligrams per cubic meter (mg/m3). Two samples exceeded the OSHA standard of 15mg/m3. Styrene values were all below the OSHA standard of 435mg/m3. Eighteen employees exhibited early signs of carpal tunnel syndrome (CTS) with symptoms of nocturnal numbness, swelling, and pain. Postures assumed during work included wrist flexion and extension, ulnar and radial deviation of the wrist, and open hand pinch. These postures have been associated with CTS. The authors conclude that a health hazard did exist from tasks involving repetitive hand and wrist movements. Exposures to cured resin particulates exceeded the nuisance dust criteria. Recommendation for decreasing the incidence of CTS and exposure to cured resin dusts are provided.
