In response to a request from the Safety Director at Steiger Tractor, Inc., located in Fargo, North Dakota, an evaluation was made of possible hazardous conditions at that facility due to exposures to xylene (1330207), aromatic naphtha (8030306), isopropyl- alcohol (67630), oil mist, trichloroethane (71556), molybdenum (7439987), iron-oxide (1309371) fumes, chromium (7440473), manganese (7439965), trichloroethylene (79016), fluoride (16984488), toluene (108883), total dust, and lead (7439921). These exposures supposedly occurred during the manufacturing and assembling of large farm tractors, of which about 20 are produced daily at this firm. Of 37 samples, one exceeded the most recent hygienic standards for iron-oxide (10 milligrams per cubic meter). When iron-oxide and manganese were combined, concentrations frequently approached the most recently established limits. Combined concentrations of isopropyl-alcohol plus aromatic naphtha and xylene plus aromatic naphtha exceeded the most recent standards in three of 17 samples. Some welders had a history of respiratory complaints including chest pain and coughing. The authors conclude that workers were exposed to excessive levels of iron-oxide and combined exposure to isopropyl- alcohol plus aromatic naphtha, and xylene plus aromatic naphtha. The authors recommend that the already existing ventilation system be corrected and to operate more effectively in the welding stations. Welders should be educated regarding the proper maintenance of the ventilation equipment.
