The company mined and refined ore bearing gold and other metals. Personal, breathing zone, and area air samples were collected at the 2,150 foot level and analyzed for diesel emission particulates. Five of the up to 20 employees who worked at the 2,150 foot level were working in the area of the survey; two drove front end loaders. Results of air samples collected at the rock pick area, maintenance barn, and 49 raise and haulage ways of the 2,150 foot level showed ambient airborne concentrations of the contaminants measured to be below current federal and consensus standards as well as NIOSH recommended criteria. There was felt to be insufficient information available to evaluate the long term health effects of diesel emissions to the underground miners. The authors recommend that the manufacturer's maintenance schedule be adhered to as closely as possible and that catalytic converters be changed as needed.

The evaluation was requested by the U.S. Department of Justice on behalf of an unspecified number of inspectors employed by the Immigration and Naturalization Service (SIC-9221) and the Bureau of Customs to determine if employee exposures to auto emissions during routine inspection tasks posed a health problem. Ecolyzer monitoring devices with recorders were placed in inspection booths and concentrations of carbon-dioxide, lead, total particulate, sulfuric- acid and benzene were sampled. Lead samples were collected on filters and analyzed by atomic absorption. Benzene samples were collected on charcoal tubes and analyzed by gas chromotography and sulfuric acid samples were taken in filters and analyzed by ion chromatography. Total particulate was determined by gravimetry. Dosimeters were used to measure noise and an Ecolyzer Carboximeter was used to determine carboxyhemoglobin levels. Sample analysis indicated no detectable concentrations of sulfuric-acid and low concentrations of benzene at 0.08 milligrams per cubic meter (mg/m3), total particulates at 0.76mg/m3, and lead at 0.008mg/m3. Noise measurements were 15 percent of the recommended levels. The authors conclude that no health hazards exists at the two bridge crossings and they recommend the continuation of the practice of rotating inspectors.

The evaluation was requested by the management on behalf of approximately 125 workers. Chest X-rays of the employees were also reviewed. The OSHA standard of 10 milligrams per cubic meter (mg/CuM) for free silica was equaled in several work areas. Iron- oxide concentrations were at or below the OSHA standard of 10mg/CuM. Nickel concentrations ranged from 0.01 to 0.17mg/CuM, compared with the OSHA standard of 1mg/CuM. Chromium concentrations varied from Copper concentrations ranged from 0.15 to 0.32mg/CuM, compared to the OSHA standard of 0.1mg/CuM. Concentrations of manganese, lead, carbon-monoxide, acrolein, MDI, ammonia, and phenol were all below permissible exposure concentrations. X-rays revealed four cases of possible pneumoconiosis. The author recommends improvements in the existing medical surveillance program, at implementation of a respirator program, and improvements in housekeeping and ventilation.

An unidentified individual requested the evaluation on behalf of 12 company employees. Personal air samples taken for lead and zinc chloride fumes were well below the OSHA standards of 50 micrograms and 1 milligram per cubic meter, respectively. Area air samples for hydrogen chloride were also below the OSHA standard of 7 milligrams per cubic meter. Nine employees reported episodes of eye, throat, nose, and sinus irritation, and occasional chest tightness. Bulk sample analysis of the top of a work table indicated the presence of 2 to 5 percent chrysotile (12001295) asbestos. NIOSH concluded that the employees were not exposed to potentially toxic concentrations of lead and zinc chloride fumes or hydrogen chloride. They recommend that local exhaust ventilation be installed for the assembly operators and that the worktable surface be replaced with a nonasbestos material.

The evaluation was requested by an authorized representative from Local 3-495 of the Oil Chemical and Atomic Workers International Union on behalf of an unspecified number of employees. Ethyl-ether (60297) concentrations ranged from 90 to 712 parts per million (ppm), exceeding the OSHA standard of 400 ppm; nitroglycerin (55630) ranged from undetectable to 0.89 milligrams per cubic meter (mg/m3), will within the OSHA standard of 2 mg/m3; lead (7439921) ranged from undectable to 0.063 mg/m3, exceeding the OSHA standard of 0.05 mg/m3; and coal tar pitch volatiles ranged from undetectable to 0.1 mg/m3, within the OSHA standard of 0.2 mg/m3. All other samples were below their respective standards. The medical interviews and record review revealed several cases of previously diagnosed asbestosis and heart disease. The author concludes that a potential health hazard existed as a result of employee exposure to ethyl ether, nitroglycerin, lead, and coal tar pitch volatiles. He recommends that an educational program be established, that employees be provided with daily changes of protective clothing, that the respirator program be reviewed, that general work practices be improved, that all exhaust systems be reevaluated and systems be periodically maintained, and that a standard operating procedure be established for all employees who handle asbestos.

A request was received from the owners and operators to reevaluate a previously determined health hazard from lead exposure during radiator repair. Lead concentrations in personal breathing zone samples ranged from 0.01 to 0.06 milligrams per cubic meter (mg/CuM) and general room lead concentration was 0.03mg/CuM. The milliliters (ml), which was within the upper limit of normal whole blood of 40 micrograms per deciliter. Two of the FEPs which ranged from 21 to 70 micrograms per 100ml were slightly above the upper value of 50 micrograms per 100ml. The authors conclude that a potential health hazard still exists. They recommend hygiene work practices, installation of local ventilation and annual blood lead checks to reduce the hazard.

After disassembling and cleaning the used radiators, they were reassembled using soldering wire composed of lead and tin. Analysis of breathing zone air samples indicated lead exposures which exceeded OSHA standard (0.05 milligrams per cubic meter) in four of the six samples taken. Lead levels in the blood of three workers showed that the two radiator repair persons had levels slightly in excess of the upper limits of normal, and higher than the other employee. One radiator repairman demonstrated a free erythrocyte protoporphyrin (FEP) concentration which was significantly elevated. The authors conclude that a potential health hazard existed from overexposure to lead at this facility. The authors recommend that smoking, eating, and drinking be prohibited in the work area; that workers exercise good personal hygiene; that local ventilation be installed over the booths where the radiators are melted down; that workers be given clean clothes at the start of each shift; that dirty clothes remain at the facility for cleaning; and that workers have blood lead levels checked annually.

The city of St. Bernard requested the investigation to determine if hazards from airborne inorganic lead (7439921) existed at the range during qualification shooting tests of service revolvers for 10 to 12 police officers. Personal breathing zone air samples were taken on 10 officers while firing their revolvers. Analysis was performed by atomic absorption spectroscopy. Ventilation measurements and smoke tube observations were taken to evaluate the dilution ventilation system at the range. Shooters were exposed to lead concentrations ranging from 0.17 to 32.5 milligrams per cubic meter (mg/m3), with a mean of 9.7mg/m3. The OSHA standard for lead is 0.05mg/m3 for an 8 hour time weighted average exposure. Although the shooters only use the firing range for 10 to 15 minutes per month, the authors conclude that use of the firing range presents potential health hazards. They recommend corrections in the improper design of the range and ventilation system to ameliorate potential health hazards from lead exposures.
