In response to a request from a management representative of Rubbermaid, Inc. (SIC-3089), a study was begun of possible exposures to airborne formaldehyde (50000), and total and respirable dust at the Reynolds, Indiana facility. The facility employed about 150 persons in the manufacture of thermoset plastic cookware products. In the Compounding Department, melamine/formaldehyde powder was compressed into small pellets which were transported to the Press Department and molded into the desired shape. Pieces were then sent to the Product Process Department where parts were trimmed and packaged. There was no local exhaust system for the presses. Personal breathing zone airborne formaldehyde concentrations ranged from 0.52 to 1.75 parts per million (ppm) for nine press operators. Seven exceeded the Permissible Exposure Level of 0.75ppm. Area samples for formaldehyde ranged from 0.23 to 1.98ppm. Total dust concentrations in the Bipel booth were 2.25 and 2.47mg/m3 and respirable dust concentrations were 0.69 and 0.56mg/m3. The booth effectively contained the dust generated during that operation. Very low quantities of toluene (108883), styrene (100425), isopropanol (67630), and 1,1,1-trichloroethane (71556) were detected. The author concludes that a health hazard for press operators existed from formaldehyde exposures. The author recommends that engineering controls be used to reduce formaldehyde exposure.
