Survey was requested by the United Steelworkers of America. Environmental and medical studies were performed in March, 1981. A followup medical survey was conducted in March, 1982. Two personal breathing zone samples in the metal pouring area indicated exposure to carbon-monoxide (630080) (CO) at 58 and 94 milligrams per cubic meter (mg/m3). The NIOSH standard is 39mg/m3. Personal breathing zone samples for formaldehyde (50000) indicated exposures of 0.18 to 0.50mg/m3. NIOSH classifies formaldehyde as a potential carcinogen and recommends exposures be kept to a minimum. Exposures to respirable free silica (14808607) were 0.10 to 0.12mg/m3, in excess of the NIOSH standard of area who had worked there prior to the implementation of engineering controls indicated the frequent occurrence of hazy vision and respiratory irritation during earlier work experience. The authors conclude that a health hazard exists from overexposure to free silica and CO. Exposure to formaldehyde should be minimized. The authors suggest that earlier exposure to aliphatic amines caused complaints of hazy vision and respiratory problems.

Trona mining was carried out at the site; the facility employed approximately 1,300 people, with about 1,000 of these being miners and maintenance personnel. An industrial hygiene survey was conducted over three shifts on 2 days. Ambient air samples were collected for total dust, respirable dust, free silica (14808607), trace metals, asbestos (1332214), ammonia (7664417), nitrogen-dioxide (10102440), particulate aromatic hydrocarbons and formaldehyde (50000). Trona alkalinity was also measured. Some excessive levels were noted for total dust and ammonia. There was no asbestos or crystalline silica found, and exposures to trace metals, formaldehyde and nitrogen-dioxide were not considered significant. Other contaminant levels were insignificant. The author notes that trona should be considered a primary skin irritant, able to produce contact dermatitis. The author recommends that efforts be made to reduce contact with trona, that cartridge respirators for ammonia should be available during tamping and after blasting, and that ventilation and respirators be used to reduce total dust exposure in underground mining activities.

Personal and area air samples were analyzed for zinc (7440666), iron-oxide (1332372), lead (7439921), nickel (7440020), chromium (7440473), xylene (1330207), methyl-isobutyl-ketone (108101), cellosolve (110805), ethanol (64175), and isopropanol (67630). An earlier study by Environmental Research Group (ERG) was evaluated. Iron-oxide concentrations were 5400 to 9900 micrograms per cubic meter (microg/m3), (evaluation criterion: 5000microg/m3), nickel from 720 to 850microg/m3: (15microg/m3) and chromium from 650 to 1100microg/m3: (25microg/m3). Chromium concentrations taken by ERG were 1 to 270microg/m3. ERG found four samples exceeded the evaluation criterion for zinc (criterion: 5000microg/m3); five for lead (500microg/m3) and seven for chromium (microg/m3). The combined exposures to organic compounds during C-191 painting were 88 and 93 percent of the evaluation criteria for two samples. ERG found silica (14808607) exceeded the evaluation criteria of 50 micrograms per cubic meter. The author concludes that workers may have been overexposed to iron-oxide, zinc, lead, nickel, silica, and chromium. Exposures were generally below OSHA standards, but above NIOSH standards. Exposure controls are recommended.

(1982) Public Services Company of Colorado, Pueblo, Colorado. (Click to open report) Local 111 of the International Brotherhood of Electrical Workers requested an evaluation of fly-ash, silica, and arsenic exposures to workers who repair electrostatic precipitators at the Public Service Company of Colorado (SIC-4911), Pueblo, Colorado. On July 18 and 19, 1981, all eight workers were monitored for crystalline silica, total dust particulates, arsenic (7440382), lead (7439921), selenium (7782492), and cadmium (7440439).

Most respirable and total particulate breathing zone air samples exceeded the OSHA standards of 10 milligrams per cubic meter (millig/m3). Arsenic concentrations peaked at 0.01millig/m3, above the evaluation criteria of 0.002millig/m3. One sample for silica exceeded the evaluation criteria of 0.05 milligrams per cubic meter. Three workers reported they had skin problems due to fly-ash. One worker had a significant loss of pulmonary function. The authors conclude that a potential health hazard exists from over exposure to particulates, arsenic, and crystalline silica. The exposure to fly- ash during cleanout does not appear to have resulted in pulmonary disease. They recommend shower facilities, a respiratory program, shaving so that respirators will fit properly, and yearly physical examinations.

Rollins was in the hazardous waste treatment business and had many petroleum and petrochemical firms as clients. A total of 87 air samples and 36 personal air breathing samples were collected and analyzed for cyclohexane solubles as well as for anthracene (120127), fluorene (86737), naphthalene (91203), indan (496117), and indene (95136). Cyclohexane solubles were found in 29 of the personal breathing zone samples at a mean concentration of 280 micrograms/cubic meter (microg/m3). The cyclohexane soluble fraction of total airborne particulates exceeded both NIOSH and OSHA standards for coal-tar- pitch volatiles. Persistent widespread exposures to benzene (71432), toluene (108883), and xylene (1330207) vapors were reported, suggesting that there were liquid sources of these materials at this site. Exposure was also excessive to crystalline silica (7631869) and noise. An excess of respiratory and eye irritation was noted among the employees and excess eye irritation among citizens of the town of Alsen. The authors conclude that workers were overexposed to noise and crystalline silica, experienced a high incidence of respiratory and eye irritation, and had more central nervous system symptoms than comparison workers. The authors recommend that basic hygiene should be improved by the installation of showers and adequate changing and eating facilities, that storage facilities for protective equipment be improved, that operations likely to induce inhalation or dermal exposure should be discontinued or modified, that waste should be labeled to indicate its hazardous properties, that personnel operating the landfill be monitored for silica and noise exposure, that medical surveillance be established, and that health programs be modeled after those recommended for coke oven, asphalt, and coal-tar-pitch workers.

Area and personal samples were collected and former and current workers were radiographically screened for silicosis. The median concentration of respirable crystalline silica meter. The range was from undetectable amounts of dust to 350 micrograms per cubic meter. Concentrations in the silo and millroom exceeded NIOSH standards. Out of 47 past and present workers, complicated silicosis was diagnosed in 5 of the present workers and 1 of the former workers. All had been exposed to silica prior to 1972 when dirtier industrial processes had been employed in the facility. NIOSH recommends that general housekeeping be made more rigorous, that several leaks be repaired, and that dust concentrations be kept below the NIOSH standard by means of engineering controls. When concentrations exceed the standard respirators should be used. Industrial hygiene monitoring should be performed at least twice a year and medical records should be kept for at least 30 years after the termination of a worker's employment.

In addition, medical questionnaires were administered and blood lead (7439921) concentrations were analyzed. The potential threat of Legionnaires Disease was also stressed. An authorized employee representative requested the evaluation of behalf of an unspecified number of workers. Atmospheric lead concentrations ranged from 26 to 162 micrograms per cubic meter, compared with the NIOSH recommended standard of 50 micrograms per cubic meter as an eight hour time weighted average. Carbon-monoxide and silica concentrations were not found in toxic concentrations. Heat stress measurements with a wet bulb globe thermometer (WBGT) ranged from 86 degrees F to 102 degrees F WBGT. The NIOSH recommended criteria for occupational exposure to hot environments requires that certain work practices be initiated when the exposure is continuous for one hour and the time weighted average WBGT exceeds 79 degrees F for men or 76 degrees F for women. The clinical presentation of employee symptoms was not typical of Legionellosis. Eight enamelers had blood lead concentrations greater than 39 micrograms per milliliter. The 116 other employees all had blood lead concentrations below 40 micrograms per milliliter, considered the upper limit of normal. The authors conclude that the principle cause of employee symptoms was the extremely hot working environment, and that elevated atmospheric lead concentrations, contributed to increasing blood lead in some enamelers. They recommend several measures to reduce heat stress, a reduction of dust concentrations, implementation of good housekeeping, and medical monitoring of affected workers.

The evaluation was requested by the City of Colorado Springs Department of Public Utilities on behalf of the 72 workers at the Martin Drake and R.D. Nixon facilities. Breathing zone and area air samples were collected for analysis. Workers were exposed to fly ash and coal dust containing respirable free silica at concentrations that exceeded the respective OSHA standards of 5.0 and 2.0 milligrams per cubic meter (mg/cu m). Exposures to arsenic (7440382) also exceeded the OSHA standard of 0.01mg/cu m. Exposures to up to 0.1 part per million of hydrazine (302012) were detected when the agent was added to dilution vessels. No hazardous exposures to trace metals, chlorine (7782505), asbestos (1332214), amines, or mercury (7439976) were identified. Sulfur-dioxide (7446095) exposures were below the OSHA limit of 13mg/cu m, but exceeded the NIOSH limit of 1.3mg/cu m. The author concludes that workers at these power stations are exposed to hazardous amounts of free silica in fly ash and coal dust, arsenic, hydrazine, and sulfur- dioxide. Recommendations are included for the use of respiratory protection, medical surveillance, hazard area designation, and engineering improvements.

A representative of the International Brotherhood of Painters and Allied Trades, Painters Local 4, requested the evaluation on behalf of approximately 30 workers. Previous air samples revealed lead concentrations about 100 times the OSHA standard of 0.05 milligrams per cubic meter (mg/cum). One sample for crystalline silica was 2.74mg/cum, compared with the CAL/OSHA calculated standard of 2.73mg/cum. A previous audiometric screening indicated occupational hearing loss among 38 percent of those tested. All blood lead concentrations were below the NIOSH recommended limit for occupationally exposed workers of 40 micrograms per deciliter. Lung function test revealed no restrictive disease, and the four cases of mild obstructive disease that were discovered had normal chest X-rays of the 29 subjects X- rayed, four abnormal individuals were identified but none of the abnormalities were indicative of silica related disease. The authors conclude that there was no lead or silica related hazards, although a significant amount of occupational hearing loss was noted. They recommend medical monitoring of workers exposed to lead, crystalline silica, and excessive noise levels, implementation of a noise control program, workers education, and use of double lens air hoods.

A representative of the United Steelworkers of America, Local 7084, requested the evaluation on behalf of workers in the milling operation, refinery operation, and the assay office. All personal air samples for lead in the refinery and furnace area of the assay office contained concentrations above the OSHA standard of 50 micrograms per cubic meter ranging from 67 to 12,300 micrograms per cubic meter. Two of three air mercury samples in the refinery and the mill exceeded the NIOSH recommended standard of 0.050 milligrams per cubic meter (mg/CuM), ranging from 0.048 to 0.070mg/CuM. In the assay office, all air samples for respirable silica exceeded the NIOSH recommended standard of 0.05mg/CuM, ranging from 0.15 to 1.33mg/CuM. Three of nine samples for respirable particulate dust exceeded the American Conference of Governmental Industrial Hygienists standard of 5.00mg/CuM, ranging from 0.36 to 22.28mg/CuM. Asbestos air concentrations were less than the NIOSH recommended standard of 0.1 fibers per cubic centimeter. All six air samples for hydrogen- chloride in the refinery were below the OSHA standard of 7.0mg/CuM. Total and respirable particulate dust concentrations in the furnace charging operation exceeded their corresponding standards. The authors conclude that a health hazard from overexposures to lead, mercury, silica, and total respirable particulates existed at this facility. They recommend worker education, medical surveillance, and several control measures.
