(1974) N. L. Industries (Hoyt Plant), Granite City, Illinois. (Click to open report)
Investigation of hazards associated with the prophylactic administration of calcium-disodium-versenate (23411349) for controlling potential effects of overexposure to lead (7439921) reveals no health hazard from prolonged oral administration of the compound. Blood lead analyses of employees, medical interviews, and environmental measurements indicate a severe health hazard from exposure to lead. Recommendations are made for reducing lead exposure, including periodic medical examinations, respira... (Click to show more)
(1974) Southern Steel and Wire Company, Fort Smith, Arkansas. (Click to open report)
Air samplings and interview of employees in the plating department of a plant producing refrigerator shelves and baskets lead to the conclusion that emissions from the acid tanks and welding operations are not toxic. Evaluation methods are described for chromates, cyanide (57125), and hydrochloric acid (7647010). Recent modification of the ventilation system has resulted in improvement of respiratory and eye irritation problems reported earlier.
(1973) Central Main Power Company, Yarmouth, Maine. (Click to open report)
An environmental and medical evaluation of sulfur-dioxide (7446095), vanadium (7440622) containing dust, and respirable dust containing silica (7631869) at an electric power plant indicates that the gas and the dust are non-toxic at the concentrations found in the plant. Toxic effects of sulfur-dioxide include burning sensations, dryness and pain in the nose and throat accompanied by a dry or productive cough. Symptoms of vanadium poisoning are lung irritation leading to chest tightness, congest... (Click to show more)
(1973) Cincinnati Branch Federal Reserve Bank of Cleveland, Cincinnati, Ohio. (Click to open report)
Evaluation of hazard from exposure to lead (7439921) and ink dusts generated in the mechanical destruction of United States currency and food coupons in a bank indicates that under conditions found at the time of survey concentrations of lead and nuisance dust are not toxic, the standards being 0.2 and 15 milligrams per cubic meter, respectively. Symptoms of lead intoxication are given as fatigue, exhaustion, irritability, loss of weight and appetite, and abdominal discomfort, in ordinary cases,... (Click to show more)
(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 for full summary)
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.(Click to show more)
(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.
