Data are given for the toxic effects and standard concentration of the chemicals, and the respirable fractions for inert or nuisance dusts. Results indicate that the chemicals are not toxic and the nuisance dust levels not hazardous in the amounts used in the automotive company surveyed. Recommendations include installation of local exhaust ventilation, and dilute ventilation in specific areas, supply of fresh air to the toe-in pits in assembly lines, improved housekeeping, respirators for painters, provision of a maintenance program to control vapors, mists and gases, and environmental monitoring in areas where employees are significantly exposed to carbon-monoxide, including blood analysis for carboxyhemoglobin.

The substances evaluated include aluminum-oxide (1344281), silicon carbide, iron-oxide (1332372), quartz (14808607), and tremolite (14567738), and the standard concentration is given for each substance. The physical agent evaluated, noise, has a standard level of 90 decibels. The silica (7631869) dust levels are found to exceed the Federal silica standard in the aluminum oxide separation area, inspection and boxing area, material handling area, special refracting area, and batch-mixing area. The tremolite concentrations exceed the standard in the batch mix area. No radiographic or other evidence is found for any serious respiratory problem from the dusts, although much dust is found accumulated in workers' nose at the end of the day. Recommendations include replacement of tremolite by a non-fibrous material; installation of a local exhaust system on the vibrating screens and hoppers, improved housekeeping, provision of respirators and ear protectors, periodic medical examination, and introduction of a hearing correction program.

(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...

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 of prolonged inhalation of asbestos include pulmonary fibrosis and asbestosis, respiratory insufficiency, and cardiac failure. Physical agents include: hot environments which create heat fatigue characterized by decreased ability to concentrate, tiredness, and irritability, heat collapse, exhaustion, or syncope. Recommendations include adherence to the Federal rules and NIOSH standards relating to exposures to hot environments, and provision of cloth coveralls instead of paper coveralls, and laundering services.

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 levels to within standards of 90 decibels by instituting engineering controls, establishment of a hearing conservation program including audiometry, and use of personal protective devices. Symptoms of Teflon fume fever are given with effects of smoking Teflon- contaminated cigarettes, which include chills, nausea, vomiting, body and joint pains, sweating, weakness, and dry cough. Polytetrafluoroethylene is not considered damaging to skin when used at ordinary temperatures. Above 400 degrees centigrade, perfluorisobutylene and carbonyl-fluoride (353504) are formed by the pyrolysis of Teflon.
