Year Published and Title
(1976) Hersey Products Company, Dedham, Massachusetts. (Click to open report) A health hazard evaluation of employee exposure to air contaminants in the Bronze Foundry (SIC-3362) of the Hersey Products Company reveals that 27 percent of the personnel respirable samples in the coremaking, molding, shakeout and fettling areas showed exposures to crystalline silica in excess of the NIOSH recommended standard, to the effect that coremakers, molders, utility men on shakeout and fettlers are exposed to potentially toxic concentration of airborne respirable crystalline silica (7...

The concentrations of formaldehyde (50000) do not exceed the evaluation criteria, although evidence exists that irritant toxicity to this agent is present in the exposed workers. The levels of toluene (108883) encountered cannot account for infrequent nose and throat soreness elicited by 2 workers. Bronze alloy furnace tenders and pourers are frequently exposed to lead levels in excess of the recommended standards; the same is valid for casting chipping and grinding personnel, who also undergo excessive copper (7440508) dust exposure.

The sampling was performed using 37 millimeter diameter membrane filters of 0.8 micron pore size which were mounted in three piece cassettes. An airflow of 2 liters per minute was maintained through open face filters using personal sampling pumps. Phase contrast microscopes at 400x magnification were used to make the determinations. Twelve different rooms in all were sampled and the locations included desk tops, file cabinets, tables and credenza. At no location was there a fiber concentration over 0.01 fiber/cubic centimeter. Bulk samples were taken from structural steel supports in the building for analysis as well. Samples were taken from five rooms; the amount of asbestos determined in the samples ranged from 15 to 20 percent. It had been thought that asbestos was used during the construction of the building only as high as the fourteenth floor, but this study demonstrated that asbestos was used throughout the entire building.

An evaluation request came from an authorized representative of approximately 150 affected employees. All samples were below federally acceptable levels of 2.4 milligram per cubic meter (mg/m3) for coal dusts, 2.5 mg/m3 for fluorides, 5 mg/m3 for manganese (7439965), and 0.2 mg/m3 for PPOM. Samples of PPOM showed BaP content to be below minimum detectable concentrations. None of the workers showed evidence of carbon pneumoconiosis. The authors recommend using NIOSH approved respirators, making respiratory air quality checks, establishing a respiratory maintenance program, controlling contaminants at the source, using vacuum or wet methods for cleaning operations, starting maintenance programs for all machinery, routine wetting of yard area, dampening of spills or accumulations of pitch to minimize dust generation, using protective clothing for employees, and using safety glasses. The authors further recommend that possible worker exposure to asbestos be assessed.

The survey was prompted by a request from an authorized representative of the 350 affected employees regarding exposure to hazardous concentrations of beryllium and development of beryllium lung disease. Environmental sampling revealed that employees in the foundry, arc, scrap remelt, calcine, Detroit, and atomizing areas were exposed to toxic concentrations of beryllium dust. Medical evaluation resulted in the identification of 1 case of beryllium dermatitis, one case of beryllium pneumonitis and 9 workers with chronic beryllium pulmonary disease. Excessive noise levels that could result in noise induced hearing loss were recorded in the Detroit room. Recommendations are made for control of environmental exposure of employees to the potentially toxic substances and for medical surveillance of exposed employees.

The attorney had recently attended a conference where asbestos exposure was the major topic, and was concerned as individuals in that building, and in the office he now occupied, had died of cancer. The study consisted of eight general air samples taken in the secretary's office, the attorney's office and in adjoining offices. Bulk samples were taken from the air filter and the air duct material in the ventilation system. All area samples indicated asbestos concentrations to be lower than 0.01 asbestos fibers per cubic centimeter. No concentration of asbestos was detected in the bulk sample from the ventilation system. The author concludes that no hazard existed at this time due to asbestos exposure.

Samples of urine and pubic hair were taken for analysis. Medical questionnaires were completed and airborne concentrations of nickel (7440020), cadmium (7440439), cobalt (7440484), zinc (7440666), and iron (7439896) were determined. Workers drawn from four departments (330-A, 330-B, 340-A, and 340-B) where exposure was likely demonstrated higher levels of cadmium and nickel in their hair and urine samples than did workers from a control department where exposure was not likely. Workers in department 330-A were also among those with the highest proportion of spontaneously reported health problems thought to be job related, including upper respiratory irritation or exudation. The symptoms in these workers were possibly due to exposure to plate dust and tab welding fumes, with the latter being particularly suspect, as the group of tab welders showed higher hair and urine metal levels than all other workers. The authors conclude that workers were overexposed to cadmium and nickel. The authors recommend that the use of compressed air and sweeping for cleaning purposes be prohibited. Local exhaust ventilation should be provided for tab welding and cracker machines. All operations where nickel and cadmium exposures occur should be monitored. The exhaust systems which existed were inadequate and should be upgraded. Urine screening should be performed on a periodic basis. Chest x-rays should be part of the preemployment physical along with pulmonary function tests. Cleanliness and other general health matters should be stressed among the employees.

The survey was prompted by a request from an authorized representative of the 25 affected employees, regarding worker exposure to wood dust in the saw-sanding department. Airborne concentrations of wood dusts were toxic to helpers at the multi- blade rip and one man cutoff saws and router operator. Medical examination revealed evidence of dust induced irritation of the conjunctiva and upper respiratory tract. It was determined that the diehl rip saw helper had allergic contact dermatitis secondary to wood dust exposure. Available evidence suggested that formaldehyde (50000) and phenol (108952) were not toxic in the concentrations found. Recommendations are made for environmental control and use of personal protective equipment.

No sample was found to contain more than 1 percent asbestos and it was thus concluded that there would be no health hazard encountered during the destruction of the wall and ceiling. It was noted during the collecting of samples, however, that the workmen were using a material called Ready Mix Joint Compound, which contains asbestos. During the sanding process, asbestos fibers come off the wall and enter the room air. The author recommends that use of the mix compound be discontinued and a substitute material not containing asbestos be obtained.

Airborne concentrations of crystalline silica (7631869) dust were found to be potentially toxic in all of the surveyed work areas. Exposure measurements were taken for both respirable and total dust, and in both the personal breathing zone and work areas for molders, coremakers, mullers, laborers, floormen, pourers, melters, and grinders. Airborne concentrations of metal dusts and fumes of copper (7440508), zinc-oxide and tin-oxide were within accepted exposure limits during the period of this survey. However, lead (7439921) dust and fumes were found to be potentially toxic in breathing zone measurements for melters, pourers, and grinders. Ten of the 14 hydrogen-cyanide (74908) and all of the phenols measurements were well within accepted exposure limits for the period of this survey based on coremakers breathing zone and area samples. The other four hydrogen-cyanide samples were insufficient volume to detect below the criteria concentration. Limited area sampling and colorimetric tube measurements showed no evidence of exposure to pourers, molders or shakeout workers.
