Abstract
In response to a management request, an investigation was conducted of a new epoxy powder recycling process and epoxy powder exposures at R and S Manufacturing (SIC-3634), Columbia, Pennsylvania, a division of Lasko Metal Parts. The company produced electric motors used in oscillating fans. An epoxy powder was sprayed onto the motors and heat cured. Eight employees worked in the epoxy powder room. Personal breathing zone air samples were analyzed for C7 to C11 naphthas and 1,1,1-trichloroethane (71556) (TCE). General area air samples were analyzed for fiber identification, content of respirable dust, and crystalline silica (14808607). Only trace concentrations of wollastonite (13983170) were identified in the general air samples taken. Respirable dust general area air samples ranged from 0.20 to 0.24mg/m3. Results for crystalline silica were below the minimum detectable concentrations. Deficiencies were noted during a visual inspection of the local exhaust ventilation system. These deficiencies may have contributed to the minor symptoms of heat stress which were reported by employees. Potential lead (7439921) exposure was identified for workers in the wire department due to an inadequate exhaust hood design and poor work practices. Welding fumes from a manual spot welding station were exhausted into the factory. The authors conclude that exposures to epoxy powder were below nuisance dust criteria; however, exposures should be minimized. The authors recommend that exhaust ventilation deficiencies be corrected.
