A health hazard evaluation of Docutel Corporation in Irving, Texas, was performed in January and April, 1974. Potential hazardous exposure to metallic grinding dust, soldering fluid, petroleum oil fluid, cadmium (7440439) fumes, and welding fumes were examined. The three facilities of the company included an abrasive finishing operation (SIC-3291), manufacture of printed circuit boards (SIC- 3674), and the manufacture of automated bank and baggage handling systems. There were about 250 workers involved. Environmental samples were analyzed for cadmium, lead (7439921), tin (7440315), manganese (7439965), and methyl-chloroform (71556). Medical examinations were performed. Methyl-chloroform concentrations ranged from 12 to 18 parts per million (ppm), well below the American Conference of Governmental Industrial Hygienists criteria value of 350ppm for an 8 hour exposure. Iron concentrations ranged from 0.01 to 0.47 milligrams per cubic meter (mg/m3), less than the criteria value of 10mg/m3. Cadmium concentrations were less than 0.01mg/m3. Lead concentrations were below 0.02mg/m3. Manganese ranged from values of the latter four chemicals were well below criteria values. Workers in the soldering area complained of nasal irritations. The authors conclude that no health hazard currently exists at the facilities. Recommendations include preplacement and periodic physical examinations, provision of gloves and safety glasses for the workers handling solvents, and regular environmental monitoring of the automatic soldering machine and degreaser.
