Year Published and Title
(1975) Converse Rubber Company, Malden, Massachusetts. (Click to open report)
Environmental surveys and employee interviews conducted at the Converse Rubber Company (SIC-3021) indicate that compounders in the doubling room are exposed to excessive concentrations of airborne particulates and that brief periodic exposures to higher concentrations of zinc (7440666) stearate may produce irritation of the upper respiratory tract. Ammonia (7664417) concentrations measured are also determined to be capable of producing sensory irritation.
(1975) Converters Ink Company, Inc. Linden, New Jersey. (Click to open report)
Health hazard evaluation in an ink company based on environmental measurements in the workplace and medical interviews with employees shows that vapors of ethyl acetate, isopropyl acetate, ethanol, n- propyl acetate, n-propyl alcohol, n-heptane, isopropanol, toluene and lead, chromium, titanium dioxide and inert dust are not highly toxic to workmen, but that in the concentrations used, most of the chemicals cause minor symptoms. Measures to control exposure include relocation of the solvent pump... (Click to show more)
(1975) Diamond International Corporation, Dixfield, Maine. (Click to open report)
Environmental and medical analysis of a plant manufacturing wood products and cotton swabs indicates that no health hazard exists from lint and nuisance particulate in the cotton swab department. All samples collected are found to be well below nuisance dust standards.
(1975) Dunlop Tire and Rubber Company, Huntsville, Alabama. (Click to open report)
Environmental and medical evaluations of a plant manufacturing automotive tires reveal levels of zinc-oxide (1314132), manganese (7439965), and copper (7440508) are non-toxic; however, a high concentration of particulate dusts of unknown toxicity is determined to present a potential hazard. Recommendations are presented for control of particulate dust and for the prevention of possible contact dermatitis.
(1975) Electro-Motive Division, Plant 1, General Motors Corporation, La Grange, Illinois. (Click to open report)
Evaluation of a diesel locomotive fabrication plant (SIC-3519) reveals that odors generated by bacterial breakdown of soluble oil used as a coolant are not toxic but may cause nausea. A potentially hazardous situation exists from the inhalation of dust from a polyester resin during removal of the dust by compressed air. Recommendations include eliminating the procedure for compressed air removal of dust.
(1975) GAF Corporation Equipment Manufacturing Plant, Vestal, New York. (Click to open report)
Based upon environmental air samples, employee interviews, evaluation of work procedures, ventilation system and available toxicity information, at a manufacturing plant engaged in the fabrication of duplicating equipment (SIC-3579), the following conclusions were drawn: the cleaning tank worker is exposed to toxic concentrations of methylene-chloride (75092); the methyl-ethyl- ketone (78933) parts cleaning operation in the spray paint room poses a potential health hazard; the automatic producti...

(1975) Gorsuch Foundry Company Incorporated No., Jeffersonville, Indiana. (Click to open report)
Environmental and medical evaluations of the aluminum, brass, and bronze shops of a foundry indicate a potential health hazard from exposure to silica (7631869). Recommendations presented for the control of silica exposure include improved ventilation, improved sand handling procedures, and a medical monitoring program.
(1975) Hartman Electric Manufacturing Company, Mansfield, Ohio. (Click to open report)
Health hazard determination in an electric company shows that a high percentage of employees in three departments of a company suffer from itching and dermatitis due to exposure mainly to fibrous glass, and also to lubricants and cutting fluids. Recommendations include the use of protective clothing, personal hygiene, and periodic skin examination.
(1975) I. F. Manufacturing Company, Division of Ridge Tool, New Philadelphia, Ohio. (Click to open report)
Environmental evaluations conducted by NIOSH investigators and lack of medical symptomatology and toxicity information indicate that employees in the core room of a foundry engaged in the manufacture of a variety of tools (SIC-3546) are not exposed to toxic concentrations of triethylamine (121448) because of adopted work practices. However, triethylamine concentrations are potentially toxic in the immediate vicinity of the one core blow machine used for this cold box process. This is also true o... (Click to show more)
(1975) Ingersoll Rand Foundry Division, Athens, Pennsylvania. (Click to open report)
Personal and environmental sampling of a foundry (SIC-3339) reveals that employees performing sand mulling, pouring and shakeout operations are exposed to potentially toxic concentrations of crystalline silica (quartz) (1317799) which can cause silicosis. In addition, excessive noise levels are noted and excessive levels of methane (74828) present an explosive gas hazard. Recommendations are presented for the control of silica (7631869) dust, including maintenance of ventilation systems, local e... (Click to show more)
