Abstract
In response to a confidential request, an evaluation was made of possible adverse health effects related to workplace exposures at Flexfab, Inc. (SIC-3052), Hastings, Michigan. Flexfab manufactured lightweight, flexible, nonmetallic parts for the automotive, trucking, aircraft, aerospace, and other industries as well as for the government and military. These products included flexible hose, ducts, and connectors made of silicones, neoprenes, and other elastomers. A workforce of approximately 285 hourly employees operated three shifts per day. The results of the study showed that the workers operating the mills in the rubber room were at risk of exposure to crystalline silica (14808607) and that workers applying the sealant to flexible utility dusts were exposed to levels of tetrahydrofuran (109999) near the action limit. There was also a high incidence of upper extremity cumulative trauma disorders at this company. The authors conclude that the workers who operated the mills in the rubber room were at risk of exposure to crystalline silica. Workers who applied sealant to flexible utility ducts were exposed to tetrahydrofuran at levels near the action limit. The authors recommend that modifications be made to the ventilation system in an effort to reduce chemical and dust exposures. Specific measures to prevent and control cumulative trauma disorders are recommended.
