Local 735 of the United Steelworkers of America requested the study after workers had complained of digestive disturbances, constipation, and headaches at the lead smelter. The study was performed in September 1980 and May and October 1981. Environmental measurements were made to determine worker exposure to metal, and medical evaluations were conducted. Air lead (7439921) concentrations ranged from 159 to 4830 micrograms per cubic meter of air, all of which exceeded the OSHA lead standard of 50 micrograms per cubic meter. Nonproduction as well as production areas were contaminated. Airborne arsenic (7440382) concentrations in 4 of 11 personal samples exceeded the NIOSH recommended criterion of 2.0 micrograms per cubic meter. Medical surveys demonstrated high lead absorption, a high prevalence of low hemoglobins with grossly elevated free erythrocyte protoporphyrins, and a high prevalence of kidney function abnormalities. The authors conclude that a serious health hazard of overexposure to airborne lead and arsenic existed at Master Metals. Recommendations on engineering controls, work practices, and housekeeping to control these hazards are provided.

(Click to show more)AA survey of exposure to inorganic lead (7439921) and hexavalent chromium (7440473) at a paint spray booth at the Matryx Corporation (SIC-3494), Sharonville, Ohio, was conducted. The Corporation's Safety Coordinator requested the survey which was performed on October 1, and December 9, 1981. Personal samples for lead and chromium were collected and measured for the two spray painters. The face spray velocity of the paint spray booth was measured. Workers were interviewed and previously collected blood lead samples were reviewed. Operators were potentially exposed to airborne lead concentrations of 97 to 1356 micrograms per cubic meter (microg/m3), above the OSHA limit of 50microg/m3. Hexavalent chromium exposure was undetectable to 23microg/m3, above the NIOSH standard of 1microg/m3, but below the OSHA ceiling value of 100microg/m3. The average face velocity of the paint spray booth was 70 linear feet per minute. Blood lead concentrations of the workers were below 30 micrograms per 100 milliliters, and no health problems were reported. The author concludes that even though lead and chromium exposures were above recommended values, blood lead concentrations were within current criteria. He recommends respiratory protection and frequent filter changes in the paint spray booths.

Evaluation was requested by the International Association of Machinists and Aerospace Workers Union. A survey determined symptoms, and work history. Blood lead determinations were performed on all 152 employees. Personal and area air samples were taken. Muscle, bone and head aches were reported. Organic compounds were present at 0.02 to 0.17 parts per million concentrations. Prevalent metals were lead 7.4 to 113.1 micrograms per cubic meter (microg/m3); tin (7440315), 4.0 to 16microg/m3; and zinc (7440666), above OSHA value of 30microg/m3. Six were above the 50microg/m3 permissible limit. Other chemicals were low or undetectable. Blood lead analyses revealed eight employees, with concentrations over upper normal limit of 40 micrograms per deciliter. Decline in mean blood lead concentration of 4 micrograms per deciliter occurred over the 2 sample periods. The authors conclude that a health hazard exists from exposure to inorganic lead in the core prep and test deck area and recommend surveillance and monitoring to reduce exposure.

Employees numbered 300. 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.

Possible correlation between aplastic anemia, exposure to hydrogen-fluoride (7664393) (HF), and suspected cancer deaths was investigated. Air samples were analyzed for organic vapors, lead (7439921), and HF. Blood counts, blood lead and free erythrocyte protoporphyrin (FEP) concentrations, and pulmonary function were measured. One benzene (71432) sample (8.8 milligrams per cubic meter) (mg/m3) exceeded the NIOSH 3.2mg/m3 criterion. Samples of toluene (108883), lead, and xylene (1330207) were below NIOSH recommended exposures: 375mg/m3, 0.05mg/m3, and 435mg/m3, respectively. Only one HF sample approached the 2.5mg/m3 NIOSH evaluation criterion. Five workers reported symtoms suggesting overexposure to organic solvents; five reported breathing problems. No longterm effects on pulmonary function from HF exposure were confirmed; no clinically significant blood abnormalities except one case of aplastic anemia. Blood lead and FEP concentrations were within normal range. Data did not warrant further study of increased cancer incidence. The authors conclude that exposure hazards from various petroleum products exist (laboratory and gas loading dock). There are no lasting ill effects from HF exposure. Respiratory protection practices are recommended.

Evaluation was requested by a company representative from an unspecified number of workers. Personal and area air, and bulk ink samples were analyzed for vinyl-chloride (75014), hydrogen-chloride (7647010), phthalates, solvents, formaldehyde (50000), lead (7439921), and chromium (7440473). Employees completed medical questionnaires. Measureable amounts of formaldehyde and benzene (71432) represented potential hazards: both chemicals are potential carcinogens. NIOSH recommends exposures be kept at the lowest feasible limit. Concentrations of other agents were well below accepted criteria. Workplace ventilation was adequate. Workers did not report any work related medical symptoms, but did report cough, chest tightness, sore throat, eye and nose irritation, and headache associated with a previous company location. The author concludes that chemical exposure hazards do not exist at this company, however a hazard probably did exist at the previous work location. He recommends engineering and work place improvements if workers symptoms reoccur or if production rate increases.

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.

Personal airborne sampling was conducted to evaluate exposure to formaldehyde (50000), asbestos, lead, tin (7440315), barium (7440393), and zinc (7440666). Medical interviews were performed. Formaldehyde concentrations peaked at 0.82 parts per million. NIOSH considers formaldehyde to be a potential occupational carcinogen and recommends that exposures be maintained at the lowest feasible concentration. Four airborne samples of asbestos were above the NIOSH recommended standard of 0.1 fiber greater than 5.0 microns per cubic centimeter. Medical interviews did not reveal findings that could be attributed to asbestos, lead, or other heavy metal exposure. The authors conclude that a health hazard did exist in the brake block area since airborne concentrations of personal samples of formaldehyde and asbestos exceeded NIOSH criteria. Recommendations are made for increased environmental monitoring of airborne contaminants and for modification of employee work practices.
