Year Published and Title
(1974) The Vendo Company, Kansas City, Missouri. (Click to open report)
Workers in the welding department of a vending machine manufacturing company are found to be exposed to toxic concentrations of fumes, particulates, and gases from welding and metal finishing operations. In the degreasing department, workers may occasionally be exposed to toxic concentrations of trichloroethylene (79016), but in the paint stripping department methyl-cellosolve (109864) and methylene- chloride (75092) were not at hazardous concentrations.
(1974) Trimtex Division of William E. Wright Company, Williamsport, Pennsylvania. (Click to open report)
Toxicity determinations based upon environmental measurements, work practices analysis, employee interviews, and literature reviews indicate that asbestos (1332214) dust is not toxic at the concentrations found in a plant engaged in braiding and spooling of asbestos and fiberglass yarns. Measured concentrations are well below approved limits, with no symptoms observed for asbestos exposure.
(1974) U.S. Environmental Protection Agency, Taft Engineering Center, Cincinnati, Ohio. (Click to open report)
In this letter the Environmental Protection Agency was informed of results of air sampling for possible asbestos (1332214) exposure, conducted at the Taft Engineering Center, located in Cincinnati, Ohio. Three personal samples and one area sample were taken over a period of slightly more than 1 hour. Detected concentrations of fibers longer than 5 microns ranged from less than 0.1 to 0.2 fibers per cubic centimeter of air (f/cc). The author concludes that this level of exposure is well within th... (Click to show more)
(1974) Wheeling-Pittsburgh Steel Corporation, Mingo Plant, Mingo, Ohio. (Click to open report)
Analysis of personal air samples taken at a basic oxygen furnace of a steel mill indicates that nuisance dust in the breathing zone of workers in the basic oxygen furnace stock house and the basic oxygen furnace lime stations are at a concentration that could be toxic. Recommendations are made for the elimination of excessive exposure to lime dust and to dust created by the handling of scrap metals. Data are given for iron (7439896), magnesium (7439954), calcium (7440702), and carbon (7440440) c... (Click to show more)
(1974) Wheeling-Pittsburgh Steel Corporation, Steubenville, Ohio. (Click to open report)
Results of observational and environmental evaluation performed in the hand scarfing area of the steel mill reveal that total dust, iron-oxide (1317619), carbon-monoxide (630080), and ozone (10028156) exposures are not at concentrations hazardous to the health of workers. The evaluation was made by taking personal samples on all hand scarfers and all crane operators.
(1973) Airco Vacuum Metals Company, Berkeley, California. (Click to open report)
Environmental evaluation and medical interviews at a stainless steel ingot producing plant reveal that under the conditions of use observed, vermiculite (1318009) and basolite dusts do not represent a health hazard. The use of respirators is recommended for the moving of large amounts of the compounds and during chamber cleaning operations.
(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) Cincinnati Gas and Electric, Miami Fort Station. (Click to open report)
This letter advised the Cleveland Wrecking Company, Cincinnati, Ohio, that a study of asbestos (1332214) exposure has been made, at their request, at the Cincinnati Gas and Electric Miami Fort Station. Workers were in the process of removing insulation from a boiler at the time four personal breathing zone samples were taken, extending over a period of about 0.5 hours. During the removal operation, one worker continually sprayed the boiler with water, thus minimizing the amount of dust generated... (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.
