We carefully review our reports prior to publication, but we do make errors from time to time. We regret any typographical or other minor errors that you might find. If you find a substantive factual or data-related error, let us know. Please send an email to HHERequestHelp@cdc.gov with the report number (ex. HHE 2013-0500-7500), the authors' names, the error you are reporting, and the page number of the error. We will look into your comments, fix confirmed errors, and repost the report. Thank you for your interest in the HHE Program.
Year Published and Title
(1973) Gates Rubber Company, Braided Hose Division, Denver, Colorado. (Click to open report)
Environmental evaluation and medical studies indicate that the exposure to lead (7439921) at a rubber hose manufacturing plant is not in concentrations that are toxic to the workers. The average concentration of lead in the air is 0.087 milligrams per cubic meter. The lead levels of the workers are below 60 micrograms per 100 milliliters whole blood.
(1973) Hanford Foundry, San Bernardino, California. (Click to open report)
Environmental measurements in the breathing zone of welders and employee interviews and urinalysis for fluorides indicate that no actual health hazard exists from exposure to welding exhaust gases at a foundry facility producing corrosion and heat-resistant high alloy castings. A potential health hazard is considered to exist from exposure to welding fumes, especially of alloys containing a high percentage of chromium (7440473) and nickel. Data are given for the concentrations of iron oxide, nic... (Click to show more)
(1973) Minnesota Mining and Manufacturing Company, Little Rock, Arkansas. (Click for full summary)
Environmental survey of airborne dust and iron oxide (1332372) fumes in a mining and manufacturing plant reveals no toxic concentrations of dust or fumes, with no hazard to workers in the Coloring Department of the plant. Recommendations are made for improved housekeeping, installation of a dust collection system in the Coloring Department, relocation of stockpiles, and use of protective creams and protective clothing to prevent dermatitis from unknown contaminants in carbon-black (1333864).(Click to show more)
(1973) Mobil Oil Corporation, Augusta, Kansas. (Click to open report)
Evaluation of hazards from exposures to asbestos (1332214) dust and hot environments relevant to an oil refinery's requirement for insulators' wearing of special clothing. Survey of insulators does not indicate any symptoms attributable to overexposure to asbestos, although wearing of paper coveralls over personal clothes contributes somewhat to the problem of heat exposure. Asbestos is not found toxic at the concentrations used and found in the insulators' working operation. The toxic effects o... (Click to show more)
(1973) Modern Industrial Plastics Division, Duriron Company, Dayton, Ohio. (Click to open report)
Environmental survey of the hazards arising from Teflon (9002840) dust and noise in a plastics industrial unit. Total dust air concentration levels obtained from 23 persons and four general area samples range from 0.0 to 5.5 milligrams per cubic meter, as against the standard of 15 milligrams per cubic meter. Recommendations include improved housekeeping program to keep dust sources to a minimum, prohibition of smoking in areas where Teflon is cut, machined, or processed, reduction of noise leve...

(1973) N. L. Industries, Inc. Titanium Pigment Division St. Louis, Missouri. (Click to open report)
Environmental survey and medical evaluation of workers in a plant producing titanium dioxide pigment from ilmenite ore, involving various ore dressing techniques, including digestion, bleaching, washing, calcining, and milling. Monoisopropanolamine or MIPA and triethanolamine or TEA had been found to cause dermatitis in use prior to the inspection; titanium dioxide dust levels are found to be below standard limits. No pulmonary or noncutaneous health problems are identified. Noise levels are fou... (Click to show more)
(1973) Penn Rare Metals Division, Kawecki Berylco Industries, Inc., Revere, Pennsylvania. (Click to open report)
Air samples collected in the breathing zone of workers employed at a pure metal processing plant reveal that exposure to cesium (7440462) and rubidium (7440177) and their salts is minor and all exposed employees are asymptomatic. Assays to assess the possible absorption of the metals in the blood and urine yield negative results. The results indicate that the employees show no effects from exposure to cesium and rubidium in their working environment.
(1973) PPG Industries, Inc., Clarksburg, West Virginia. (Click to open report)
Air sampling and medical evaluation performed at a glass cutting and packaging operation reveals that salicylic dust, a component of Polytek glass used in the process, is toxic at the concentration used or found, causing acute irritation of the eyes, nose and throat of the workers exposed. Air concentration levels of 0.08 mg per cubic meter of salicylic-acid (69727) does not cause significant blood levels of the compound, but it does induce symptoms. Limited evaluation of the new Polytek dispens... (Click to show more)
(1973) Redmond Finishing Company, East Stroudsburg, Pennsylvania. (Click to open report)
Environmental survey and medical examination of workers in the batting department of a synthetic textiles products manufacturing plant, producing a polyester fiber filler and insulation material, indicating potentially toxic exposure to ethyl-acrylate (140885) polymer dust. No significant symptoms are reported, except for past skin discomfort by a worker. Recommendations are made for institution of engineering improvements to control the overspray of emulsion containing the polymer as well as a ... (Click to show more)
(1973) Reynolds Metals Company, Bauxite, Arkansas. (Click to open report)
Air sampling and medical investigations at an industry manufacturing alumina (1344281) from bauxite indicate that alumina dust and sinter dust are toxic at the concentrations found during the evaluation, while crystalline silica and fluorides in the cryolite area are not toxic in the concentrations measured. Workers in the alumina bagging area noted occasional burning of the nose and had a history of skin irritation, although dermatitis was well controlled by the use of protective creams.
