(1978) Jefferson Chemical Company, Port Neches, Texas. (Click to open report) An investigation to determine the effects of various chemical exposures on workers was made at the Jefferson Chemical Co. (SIC- 2819) which produces a variety of chemical substances, many of which serve as feedstock to produce the final products. The majority of the substances are produced and handled in closed reactor systems and distillation units. The final products are loaded into tank cars, trucks and drums.

(SIC- 2819) which produces a variety of chemical substances, many of which serve as feedstock to produce the final products. The majority of the substances are produced and handled in closed reactor systems and distillation units. The final products are loaded into tank cars, trucks and drums. General area and personal samples for organic vapors were obtained. Private interviews with employees selected at random were conducted and nondirected medical questionnaires were compiled. The first aid facilities and medical programs were also reviewed along with selected blood lead (7439921) data. A hazard to the health of laboratory workers did not exist at the time of the surveys as indicated by air sampling results. A potential health hazard existed for workers assigned to the refinery gas feedstock unit, due to benzene (71432) vapor exposures as indicated by air sampling results. A health hazard was not indicated for employees of the ethanolamine (141435) production unit based on the results of the type of air samples obtained. A health hazard was not indicated for employees of the phenol (108952) processing unit based on the results of the type air samples obtained. A determination of potential health hazards was not possible for the Cell Renewal Area due to the operation not being on line at the time of the surveys. A potential health hazard existed for employees of the DDM production unit based on work practice observations and spent catalyst dust analysis. The spent catalyst contained approximately 0.6 percent aniline (62533) and 9 percent diaminodiphenyl-methane (DDM) isomers by weight. The workers were not adequately protected for the catalyst dumping operation.

(1978) KW Battery Division, Skokie, Illinois. (Click to open report) Environmental and personal air samples were analyzed for inorganic lead (7439921) at KW Battery Division (SIC-3691) in Skokie, Illinois, on May 17 to 19, June 2 to 3, and August 11 to 12, 1977. The Personnel Relations Manager of the facility requested the evaluation on behalf of approximately 130 production workers. Lead concentrations ranged from 0.02 to 5.81 milligrams per cubic meter (mg/CuM), compared with the proposed OSHA standard of 0.10mg/CuM. Thirteen of 101 workers had blood lead conce...

The Personnel Relations Manager of the facility requested the evaluation on behalf of approximately 130 production workers. Lead concentrations ranged from 0.02 to 5.81 milligrams per cubic meter (mg/CuM), compared with the proposed OSHA standard of 0.10mg/CuM. Thirteen of 101 workers had blood lead concentrations in the 60 to 80 micrograms per 100 milliliter range and 2 in the 80 to 100 micrograms per milliliter range. Blood lead concentrations above 60 micrograms per 100 milliliters are considered a health hazard. The author recommends several ventilation modifications and work procedural changes to reduce lead exposure, continuation of the lead monitoring program, and worker education regarding the reproductive effects of lead exposure.

(1978) Mark Steel Corporation, Salt Lake City, Utah. (Click to open report) Environmental surveys were conducted on June 20 and 21, 1978, to evaluate the potential health hazard of an abrasive, made from lead smelter slag, used in the abrasive blasting operation at the Mark Steel Corporation (SIC-3325) in Salt Lake City, Utah. The evaluation was requested by a company representative on behalf of two affected employees. The bulk abrasive grit sample contained less than 1 percent silicon-dioxide (7631869).

The evaluation was requested by a company representative on behalf of two affected employees. The bulk abrasive grit sample contained less than 1 percent silicon-dioxide (7631869). Three of four respirable dust samples contained no silica and concentrations of respirable dust ranged from 3.4 to 4.7 milligrams per cubic meter (mg/m3), which were below the OSHA standard of 5.0mg/m3. No cadmium (7440439) was detected in any of the samples. Lead (7439921) concentrations ranged from 0.25 to 2.34mg/m3, exceeding the from 29.0 to 69.1 micrograms per cubic meter, exceeding the 10.0 micrograms per cubic meter OSHA standard. The author concludes that employees working at the abrasive blasting operation are potentially exposed to toxic airborne concentrations of inorganic lead and inorganic arsenic, and that employees may be exposed to excess concentrations of crystalline silica. A substitute grit should be considered, a medical monitoring program should be instituted, and a respiratory protection program should be provided for concerned employees.

(1978) Mesta Machine Company, West Homestead, Pennsylvania. (Click to open report) An investigation has been conducted to evaluate potential hazards from a cadmium babbitting operation in the erection department involved in the manufacture of equipment for steel rolling mills (SIC-3341). The babbitting section of the erecting department performs centrifugal casting of linings of oil bearings and other types of bearings. The two types of babbitt metals and their alloying elements include: 1) cadmium (7440439) base containing 97.5% cadmium and 1.5% lead (7439921), and 2) tin (74...

The babbitting section of the erecting department performs centrifugal casting of linings of oil bearings and other types of bearings. The two types of babbitt metals and their alloying elements include: 1) cadmium (7440439) base containing 97.5% cadmium and 1.5% lead (7439921), and 2) tin (7440315) base containing 89% tin, 3.5% copper (7440508), 7.5% antimony (7440360) and .25% lead. Prior to the investigation, melting of the cadmium base babbitt ceased. Thus, no environmental evaluation was conducted. The medical evaluation consisted of questionnaires administered to each worker, a directed physical examination, pulmonary function test, and blood and urine analyses. It has been determined that a hazard to the health of workers exposed to cadmium may have existed prior to the cessation of cadmium bearing babbitting operations. Elevated blood and/or urine cadmium levels (indicative of possible excessive cadmium exposure) were found in 5 out of 11 potentially exposed workers tested. In addition, two workers who showed elevated blood and urine cadmium concentrations had symptoms compatible with chronic cadmium toxicity. In addition, these two workers also suffered symptoms compatible with acute cadmium inhalation poisoning during an episode in April 1977, when cadmium ingots were mistaken for noncadmium containing babbitt ingots and were melted and poured into bearings without the respiratory precaution normally taken when working with cadmium.

This abatement period was instituted by OSHA while the facility attempted to correct violations of the airborne lead (7439921) standard. At this site both a lead recovery operation and a foundry were operational. Both were housed in one large building which used to be a grain elevator. The finished products were bearings for journal boxes of railroad cars. The lining of these bearings was composed of 87 percent lead, 3 percent tin, and 9 percent antimony. Electric furnaces melted down the scrap metal and reclaimed the lead. A total of 95 workers were screened using a zinc-protoporphyrin (ZPP) test. Fifty two of the men who had worked at high risk jobs or had a ZPP value equal to or greater than 90 microgram percent were examined by history, physical and laboratory tests. Of these, 85 percent had lead levels greater than 40 micrograms per 100 milliliters of blood and over 20 percent had levels greater than 60 micrograms. Thirty five had abnormally elevated blood pressures and a number had abnormalities of the urine and other parameters of renal function including blood urea nitrogen. During a walk through of the facility it appeared that lead or dust possibly containing lead was present in abundance on floors, worktables and clothing of the workers. The authors recommend that housekeeping be improved, that more vigorous lead monitoring and control programs be instituted, that the abatement program be reviewed to see if workers can be given additional protection, and that abnormalities of kidney function and blood pressure be followed up.

The evaluation was requested by an authorized employer representative on behalf of 92 affected workers. Respirable dust and free silica concentrations generally were below the evaluation criteria of 10 milligrams per cubic meter (mg/m3) divided by the percentage of free silica plus 2, and 0.05mg/m3, respectively; 2 of 21 free silica and 4 of 21 respirable dust samples exceeded the standards. Concentrations of lead and carbon- monoxide (630080) were well below the exposure limits of 0.1mg/m3 and 35 parts per million, respectively. Workers reported respiratory tract symptoms, however these were attributed to contagious respiratory tract infections. The authors conclude that no hazardous exposures exist at this facility, but the dusts may aggravate inflamed respiratory tract mucous membranes. They recommend that properly fitted respirators be used and the housekeeping at the site should be improved.

OSHA requested the evaluation as a follow up survey after the facility had been cited for lead exposure standard violations about 3 years previously. Zinc protoporphyrin (ZPP) tests were administered to 178 workers. Sixty two workers with ZPP concentrations equal to or greater than 90 micrograms percent or workers in high lead exposure jobs were given additional blood, as well as urinary and neurological tests. Sixty one workers had elevated ZPP concentrations. Three workers had histories of elevated blood lead, and 10 percent of the workers had histories of hypertension and kidney disease. Muscle weakness or reduced reflexes were found in 66 percent and elevated systolic, diastolic, or total blood pressure in 50 percent of the workers. Elevated creatinines and blood urea nitrogen and depressed hemoglobins and hematocrits were found in 39, 8, 10 and 11 percent of those examined, respectively. Two workers had blood lead concentrations above 60 micrograms per 100 milliliters of blood. Five percent were above 50 micrograms and 14 percent were above 40 micrograms. The authors conclude that significant numbers of workers show evidence of renal and hematological disorders. They recommend continued biological monitoring of exposed workers, initiation of an antihypertension program, and further investigation into the causes of the elevated creatinines and blood pressures observed in the workers.

Based on environmental and medical evaluations, no apparent health hazard was judged to exists. The evaluation team, 100 affected employees, and plant management agreed that the absence of respiratory illness and worker complaints was due to a new factory humidification system which was not installed at the time of the previous evaluation. Environmental sampling failed to demonstrate any detectable exposures to anti-mildew agents, while medical evaluation, including lung function studies, medical histories, and physical examinations, indicated no apparent health hazards during this evaluation.
