Year Published and Title
(1974) Ethyl Visqueen Division of Ethyl Corp., Terre Haute, Indiana. (Click to open report)
Medical and environmental evaluation of hazards from vinyl-chloride (75014) monomer in a plant manufacturing polyvinyl chloride pipe reveals a potential carcinogenic hazard in blending room areas of the plant. Air concentrations of vinyl chloride ranging from none detected to 4 parts per million are below the Federal Standard but exceed the none detectable concentration recommended by NIOSH.
(1974) Federal-Mogul Corporation, Gallipolis, Ohio. (Click to open report)
Environmental evaluations, medical questionnaires and observations indicate that a health hazard from nuisance dust and carbon-monoxide (630080) exists in a plant manufacturing automatic transmission parts for automobiles. Asbestos (1332214) and copper (7440508) concentrations are found to be well below established standards.
(1974) Golden Foundry, Columbus, Indiana. (Click to open report)
Environmental and medical evaluations of a foundry manufacturing gray iron (7439896) castings reveal toxic levels of silica (7631869), potentially toxic levels of iron oxide (1317619), and irritant toxicity of ammonia (7664417), formaldehyde (50000), and phenol (108952). Carbon-monoxide (630080), toluene (108883), and xylene (1330207) are not found in toxic concentrations. Recommendations include engineering control of silica levels, including improved ventilation; improved housekeeping; medical... (Click to show more)
(1974) Goodyear Aerospace Corporation, Commercial Plastics Division, Jackson, Ohio. (Click to open report)
Medical and environmental evaluations of a plant manufacturing sheet molded fiberglass reinforced plastic reveals xylene (1330207) concentrations in spray painting areas are not toxic to employees; fiberglass reinforced plastic dust is not present in toxic concentrations, but is the cause of active cases of dermatitis. Recommendations include use of protective clothing to minimize skin contact with dust, fans to project dust away from breathing zones, proper use of respirators, and employee educ...

(1974) Inland Manufacturing Company, General Motors Corporation, Dayton, Ohio. (Click to open report)
Exposures to coal dust and fly ash during the clean up operation of boilers are found to be below Federal standards for total dust and silica (7631869) levels. No significant symptoms were reported by interviewed workers, and samples of dust contained only 2.2% silica.
(1974) Inland Manufacturing Division General Motors Corporation, Vandalia, Ohio. (Click to open report)
Concentrations of inert nuisance dust, acetone (67641), 1,1,1- trichloroethane (71556), and methylene-chloride (75092) are not found to be toxic in an injection molding department producing rigid fiberglass backing for automotive instrument panels. Interviews with workers using a questionnaire revealed no relevant symptomatology.
(1974) Kaiser Permanente Cement Company, Lucerne Valley, California. (Click to open report)
Free silica (7631869) and iron-oxide (1317619) dust are not considered to be toxic at the concentrations measured at a cement company. Although air concentrations of asbestos (1332214) were found to be below Federal Standards on a time weighted average basis, recommendations are made to protect workers from unnecessary exposure.
(1974) Magnavox Company of Tennessee, Andrews, North Carolina. (Click to open report)
Environmental and medical evaluations in a plant manufacturing television and stereo cabinets reveal no health hazard to color patchers and spray booth operators exposed to normal-butyl-acetate (123864), methyl-isobutyl-ketone (108101), toluene (108883), and xylene (1330207). Roundtable shaper operators are exposed to potentially toxic concentrations of wood dust. Recommendations include improved plant ventilation, improved exhaust system in the roundtable shaper area, and use of respirators whe... (Click to show more)
(1974) Owens-Illinois Glass Company, Hapeville, Georgia. (Click to open report)
Environmental and medical evaluations in the forming and selecting departments of a glass plant reveal concentrations of hydrogen- chloride (7647010), sulfur-dioxide (7446095), and tin-tetrachloride (7646788) are not toxic. Sulfur-dioxide is found to cause temporary eye irritation in several employees, and airborne powdered glass dust causes dermatitis. Recommendations are made for the substitution of graphite (7782425) compounds for sulfur (7704349) as a mold lubricant and temperature stabilize... (Click to show more)
(1974) Read Plastics, Incorporated, Rockville, Maryland. (Click to open report)
Plastic dust generated in a cutting area is not found to be toxic at measured concentrations based on analysis of the acrylic plastic material, measured airborne dust concentrations, nondirected worker interviews, and observations of work practices. Noise levels produced by plastic sawing and routing operations are cited as presenting a potential hazard to hearing. Quantitative evaluation is not made of employee exposure to organic solvents.
