(1972) Asbestos study, Chemical Sealing Corporation, Kansas City, Missouri. (Click to open report)
A survey was conducted to determine environmental asbestos (1332214) exposures at Chemical Sealing Corporation (SIC-2891), Kansas City, Missouri, in March 1972. The survey was requested by a manager on behalf of 40 workers. Thirty five breathing zone samples of atmospheric dust were collected on Millipore filters. The Department of Labor emergency standard for asbestos dust exposure was 5 fibers per milliliter no more than 5 microns in length for an 8 hour time weighted exposure. One batch mixer...

The survey was requested by a manager on behalf of 40 workers. Thirty five breathing zone samples of atmospheric dust were collected on Millipore filters. The Department of Labor emergency standard for asbestos dust exposure was 5 fibers per milliliter no more than 5 microns in length for an 8 hour time weighted exposure. One batch mixer was exposed to an asbestos concentration higher than the standard; he wore an approved respirator when loading the mixers. A vacuum cleaner was not available for dust removal. Employees provided and maintained their own work clothes. The lunch room was too close to the work area, and served as an entry to the locker areas. The authors recommend confinement of asbestos mixing using a slurry instead of dry asbestos. Floors and equipment should be vacuumed and vacuums should be available for removing dust from clothing. Coveralls should be provided and maintained by management. A separate entrance should be provided for wash rooms and locker rooms, and the lunch room should be located away from the dust producing areas. (Click to show less)

(1972) Empire Detroit Steel Company, New Boston, Ohio. (Click to open report)
Evaluation of hazards arising out of exposure to heat, noise, coal tar pitch volatiles, carbon-monoxide (630080), graphite, and coal dust in the coke oven unit, coke plant department, and blast furnace department of a steel company, with report pertaining only to coal tar pitch volatiles and noise measurements. Recommendations include the use of Bureau of Mines approved respirators for pneumoconiosis- producing dust for all persons working in the coke and coal tar pitch areas, rotation of worker...

Recommendations include the use of Bureau of Mines approved respirators for pneumoconiosis- producing dust for all persons working in the coke and coal tar pitch areas, rotation of workers on top of coke ovens to prevent heat exhaustion, provision of protective clothing, implementation of engineering controls for reducing noise levels, and provision of protective devices until such controls are effected.

(1972) Ford Motor Company Rouge Plant, Dearborn, Michigan. (Click for full summary)
Respirable coal and coke dust air concentration levels measured on 2 days at an automobile factory using both personnel and general area samplers, exceeded the established coal dust standard to prevent chronic lung diseases characteristic of such dusts. Sound measurement also revealed levels exceeding the noise standards.(Click to show more) Respirable coal and coke dust air concentration levels measured on 2 days at an automobile factory using both personnel and general area samplers, exceeded the established coal dust standard to prevent chronic lung diseases characteristic of such dusts.

(1972) Lawndale Industries, Inc., Lima, Ohio. (Click to open report)
Environmental and medical survey of operations and personnel in a plant manufacturing porcelain enamel coated steel bath tubs (SIC- 3431), involving the application of ground and finish coats by electrostatic spraying which exposes men to silica (7631869). Data are given for the components of ground coat, white cover coat, and bulk samples, and also for personnel sample, industrial ventilation, and inspection and cleaning of respirators. Analysis of the bulk and personnel samples indicates that ...

Data are given for the components of ground coat, white cover coat, and bulk samples, and also for personnel sample, industrial ventilation, and inspection and cleaning of respirators. Analysis of the bulk and personnel samples indicates that finish coats contain, on an average, less than 1 percent free silica, that the ground coat contains about 5 percent free silica, and that exposure to respirable free silica at the ground coat spray area is about three times the recommended maximum of 1.4 milligrams per cubic meter. Recommendations include increasing ground coat spray booth exhaust ventilation to about 125 feet per minute face velocity, removal of the fan located at the exit end of the ground coat booth, training of operatives, preemployment and routine chest x-rays, and other medical checkups, provision of lockers, showers, and drinking fountains, and establishment of personal protection plans and safety programs.

Lead (7439921) dust air concentrations measured at a battery manufacturing plant indicate that numerous personal and general area samples throughout the plant exceed the established lead dust standard. Sound levels are found to be at, or below, the current standard of 90 decibels A. Recommendations are made to obviate the hazards to the 125 affected employees.
