Industrial Hygiene Report In-Depth Survey, Solvent Vapor Survey of Screen Printing Operations at Rand Display 40-24 22nd Street Long Island City, New York.
Worker exposures to solvents were surveyed on January 23 to 25, 1968, at Rand Display (SIC-2751) in Long Island City, New York. The company employed 25 workers. Personal and area air samples were analyzed. Concentrations of toluene (108883), xylene (1330207), methyl-isobutyl-ketone (108101), methyl-ethyl-ketone (78933), ethyl- acetate (141786), butyl-acetate (123864), cyclohexanone (108941), 1,3,5-trimethyl-benzene (108678), 1,2,3-trimethyl-benzene (526738), 1,2,4-trimethyl-benzene (95636) were well below respective OSHA standards of 100, 100, 100, 200, 400, 150, 50, 25, 25, and 25 parts per million (ppm). Some workers were exposed to concentrations of solvent mixtures in excess of the 1.0ppm OSHA standard. The author recommends improved engineering controls, use of respirators and protective clothing, careful personal and workplace hygiene habits, and education of workers about the proper use and health risks of solvents.
