Health-hazard evaluation report HETA 84-214-1633, Sheldahl, Inc. , Northfield, Minnesota

Technical Report ·
OSTI ID:6774278
In response to a request from Amalgamated Clothing and Textiles Workers Union, an evaluation was made of possible hazards at Sheldahl, Inc., Northfield, Minnesota. The facility produced flexible printed circuitry. At the facility, adhesives were mixed including solid resins such as polyester, epoxy or nylon; solvents such as methylene chloride, methyl ethyl ketone, acetone, and smaller quantities of 1,1,2-trichloroethane, methanol, 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 1752 ppm. A potential health hazard from exposure to methylene chloride exists. A less toxic material should 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.
