Abstract
In response to a request from Amalgamated Clothing and Textiles Workers Union, an evaluation was made of possible hazards at Sheldahl, Inc., (SIC-3679), Northfield, Minnesota. The facility produced flexible printed circuitry, employing about 650 workers. At this facility adhesives were mixed including solid resins such as polyester, epoxy or nylon; solvents such as methylene-chloride (75092), methyl-ethyl-ketone (78933), acetone (67641), and smaller quantities of 1,1,2-trichloroethane (79005), methanol (67561), and others; and additives such as powders, dyes, and isocyanate curing agents. Samples collected in lamination departments indicated workers were potentially exposed to methylene-chloride at levels ranging from 26 to 132 parts per million (ppm). Methylene-chloride concentrations for short term exposures were calculated to range up to 1752ppm. Combined exposures to methylene-chloride and carbon- monoxide (630080) were excessive. The company's medical log for the years 1981 to 1983 showed cases of illness compatible with methylene- chloride exposure. The authors conclude that a potential health hazard from exposure to methylene-chloride exists. The authors recommend that a less toxic material be substituted for methylene- chloride. Exhaust ventilation systems and personal protective equipment should be upgraded. Solvent soaked rags should be placed in sealable containers. Employee education should be undertaken, and medical monitoring should be conducted on a regular basis.
