Year Published and Title
(1973) Colorado Brick Company Boulder, Colorado. (Click to open report)
Determination of respirable dust, free silica (7631869), lead (7439921), manganese (7439965), chromium (7440473), iron (7439896), and carbon-monoxide (630080) in 37 personal air samples taken at a brick manufacturing (SIC-3251) facility reveals that only respirable free silica exceeds the OSHA standard. Respirable samples taken at various working locations exceeded the federal standards, with the exception of the maintenance superintendent.
(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) Robin Products Company, Warren, Michigan. (Click to open report)
Medical and environmental evaluation of hazards of exposure of plastics workers to fumes of formaldehyde (50000) (acceptable ceiling concentration 5 ppm), indicates that toxic exposure does not exist at the concentrations found in the work environment. Toxic effects of formaldehyde are prolonged dryness of the nasal mucous membranes and general discomfort. Exposures to intense noise are found to lead to loss in hearing. Recommendations include provision of protective equipment to workers.
(1973) Western Foundry Company, Tigard, Oregon. (Click to open report)
Environmental evaluation, employee response, visual observations, and employee interviews lead to the conclusion that the concentrations of furfuryl alcohol (98000) and formaldehyde (50000) found in the working environment of the air-set cure coremaking area of a foundry do not present potential toxic effects. Eye irritation and tearing experience during exposure simulating working with hot sand disappeared immediately upon cessation of exposure.
(1972) Bata Shoe Company, Inc., Belcamp, Maryland. (Click to open report)
A case of mercurialism in a shoe factory employee leads to a comprehensive search for mercury (7439976) vapor or source of mercury in all factory operations, but to no avail. Blood and urine analysis confirms poisoning by mercury. The environmental survey confirms that the source of mercury is not the shoe factory but probably a deep well in the worker's home.
(1972) NL Industries, Incorporated, Atlanta, Georgia. (Click to open report)
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.
(1972) Raybestos-Manhattan, Inc., Crawfordsville, Indiana. (Click to open report)
Environmental surveys to evaluate potential health hazards associated with the grinding, drilling, milling-slotting, and grooving operations at an iron (7439896) and copper (7440508) sintered metal parts manufacturing facility reveals that the levels of iron, copper, lead (7439921), magnesium (7439954), zinc (7440666), tin (7440315), antimony (7440360), molybdenum (7439987), graphite (7782425) and silica (7631869) dust in the air do not exceed the levels recommended by the prevailing health stan...
