A survey to measure exposure to lead (7439921), ferric-oxide (1309371), manganese (7439965), copper (7440508), chromium (7440473), xylene (1330207), toluene (108883), methylethylketone (78933) (MEK) and 1,1,1-trichloroethane (71556) was conducted at Steiger Tractor, Inc. (SIC-3523) in Fargo, North Dakota on May 15 to 17, 1979. The survey was requested by the International Association of Machinists' and Aerospace Workers Local 2525 on behalf of an unspecified number of workers. Atmospheric samples were collected and analyzed, and day shift workers were given medical studies consisting of questionnaires on general health and specific symptoms, blood sample collection and pulmonary function testing. Atmospheric concentrations of lead, ferric-oxide, manganese, chromium and copper ranged from none detected (ND) to 1.90, ND to 27.7, ND to 1.52, ND to 0.34, and ND to 0.01 milligrams per cubic meter (mg/CuM) respectively. Corresponding OSHA, NIOSH, or American Conference of Governmental Industrial Hygienists (ACGIH) 8 hour time weighted permissible exposure limits (PEL) are 0.05, 5.0, 1.0, 0.025, and 0.2 mg/CuM, respectively. Atmospheric concentrations of xylene, toluene, MEK, and 1,1,1-trichloroethylene ranged from ND to 72, ND to 103, ND, and ND to 342mg/CuM, respectively, compared with OSHA, NIOSH, or ACGIH PELs of 435, 375, 590 and 1900mg/CuM, respectively. The author concludes that overexposure to lead, ferric-oxide, and manganese did exist at this facility and recommends better hygiene practices, improved ventilation, and regular medical testing.
