The survey was prompted by a request from an authorized employee representative regarding exposures of approximately 70 affected workers to crystalline silica (7631869), lead (7439921), sulfuric-acid (7664939) and contaminants released from abrasive grinding operations. Environmental sampling revealed excessive lead exposure when lead containing steel was cut with an oxyacetylene torch. The airborne concentrations of all other contaminants were not potentially toxic, a finding supported by the lack of complaints and symptoms. Review of medical questionnaires revealed previous symptomatic conditions (respiratory irritation, eye irritation, dermatitis and dental anomalies) compatible with exposure to sulfuric-acid. Recommendations are made for maintaining a safe and healthful work environment.

Eight workers were employed at this slab yard during each shift, with three shifts per day. Samples of breathing zone air and area air were analyzed for respirable crystalline silica (14808607) and total respirable particulate matter. Measurements were also taken of sulfur-dioxide (7446095) and metallic fumes and dusts. Total respirable particulates were below the recommended limits and no detectable quantities of quartz or cristobalite were found. Airborne breathing zone concentrations of iron-oxide (1309371) ranged from 0.1 to 1.6mg/m3; of lead (7439921) from 0.003 to 0.006mg/m3; of manganese (7439965), 0.003 to 0.012mg/m3; and of copper (7440508), (0.002 to 7.0 to 10.0 parts per million (ppm); sulfur-dioxide, 0.5 to 10.0ppm; and nitrogen-dioxide (10102440), not detectable to 0.50ppm. Symptoms among the workers included cough, expectoration of dust daily, sinus difficulty, and dry mouth. Recommendations were offered concerning medical examinations and testing, respirator use, monitoring of sulfur-dioxide levels in crane cabs, installation of louvers along the south wall of the slab yard, monitoring of high carbon steel slab production, and monitoring of number 6 crude oil for benzene (71432).

It was determined that the exposures to the chemicals were not hazardous, but noise levels were found to be potentially hazardous throughout the work area during periods of frequent or prolonged power tool use. The determinations are based on environmental measurement, interviews, and observations of work practices and exposure controls. Interviews with at least 5 of 8 potentially 'affected' workers failed to reveal any pattern of symptoms, although nearly all complained of some discomfort when gluing larger projects. Recommendations are made regarding ventilation, use of a silica-free polishing compound, reduction of noise exposure and wearing of impermeable gloves.

Environmental air samples revealed that employees working in and around diatomaceous earth packing stations and in and around the conveying mechanisms and catwalks were exposed to potentially toxic concentrations of cristobalite containing dust. Employees working at the crushing stations may be exposed to excessive dust levels, but this fact was not conclusive. Mortality data seem to show a pattern of mortality excesses among the Johns- Manville population consistent with those previously documented for diatomaceous earth workers, with the rates of lung cancer and respiratory disease being higher than expected. The medical surveillance program prior to 1973 was not adequate to insure the protection of workers and, while the current program is acceptable, it will need periodic review in order to insure worker health in the future.

The survey was prompted by a request from an authorized representative of the approximately 550 affected employees regarding physical impairment, primarily a high incidence of coronary heart disease in the pot and casting departments. Environmental sampling revealed that the anode setters in the pot area may be exposed to excessive concentrations of aluminum-oxide (1344281), while fluoride exposure was not excessive. In the casting area exposure to carbon-monoxide (630080), sulfur-dioxide (7446095) and ammonia (7664417) was minimal. According to available medical data, the findings related to determining whether a high rate of coronary disease existed were inconclusive. Recommendations are made for environmental control and medical surveillance of employees.

Bean, Inc., a production facility engaged in the manufacture of tanned leather (SIC-3111) consumer items, regarding employee exposure to vapors from adhesives and solvents and also a case of nasal irritation from the dust raised in the cutting of chrome tanned leather, a health hazard evaluation was conducted by NIOSH at the above mentioned facility in Freeport, Maine, on May 13 and November 3-5, 1976. Exposure to airborne benzene (71432) in the making room was in excess of the recommended environmental criteria and, due to the potential leukemogenesis of benzene, recommendations are made to ventilate the operation and also to switch to a benzene free solvent. Charcoal tube analysis and detector tube results gave different indications of the potential hazards posed by the concentrations of toluene, hexane (110543), and ethyl-acetate in the air; in both cases, however, the airborne levels were such as to justify changes in the existing ventilation system. Due to the toxicity of the thermal decomposition products of nylon and polypropylene and the complaints of mucous membrane irritation recorded among the 19 affected workers, it is appropriate to ventilate the plastic cord cutting operation. Exposure of employees to leather, wood and synthetic rubber dust, chromium (7440473) residue in leather dust, ammonia (7664417), toluene (108883), petroleum naphtha (8030306), acetone (67641), ethyl-acetate (141786), isopropyl-alcohol (67630), butyl-acetate (123864), isobutyl-acetate (110190) xylene (1330207), and 2-ethoxyethanol are not considered to pose a health hazard. The results are based on measurement of workplace concentration of airborne contaminants, survey of process operations and control measures, and interviews with affected employees.

The survey was prompted by a request from an authorized representative of the approximately 20 affected employees to determine whether any substance found in the work place has potentially toxic effects in such concentrations as used or found. The airborne concentrations of formaldehyde (50000) and ammonia (7429905) were low enough to prevent respiratory injury but not the subjective upper eye and respiratory irritation reported by some of the workers. Workers involved in cement mixing presented dermatitis which could be minimized by use of protective equipment and other measures. The operator of a large mixed was exposed to potentially toxic levels of respirable crystalline silica (7631869). Recommendations are made for measures that can help minimize dermal and respiratory effects apparent to the manufacturing processes evaluated.

The investigation was prompted by a request from an authorized representative of employees to evaluate the potential hazard associated with employee exposure to chromate pigments. Seven affected employees were interviewed and an environmental survey was conducted by obtaining time weighted average and ceiling measurements of employee exposure to hexavalent chromium (7440473) and trivalent chromium. Based on environmental samplings, evaluation of ventilation systems, observations of employee work practices, and available toxicity information it is concluded that employee exposures to noncarcinogenic hexavalent chromium contained in sodium-bichromate (10588019), as measured during the survey, did not constitute a health hazard. All atmospheric levels of hexavalent chromium were below evaluation criteria. Although no standards exist from trivalent chromium, recommendation are made for preventing the release of trivalent chromium dust in the air. Certain employees who had experienced nosebleeds and other hexavalent chromium related problems in the past had not experienced such problems for at least 1.5 to 2 years of work, probably as a result of the installation of local exhaust ventilation to prevent exposure.
