The workroom air concentrations of crystalline free silica are found to exceed the current NIOSH standard of 0.05 milligram per cubic meter. Employees are also found to be transiently exposed to phosphine (7803512) generated in the machining of nodular iron rolls. The possibility of metal fumes and calcium-oxide (1305788) transiently exceeding the current safety limits during tapping operations is suspected because of the episodic and transient symptoms of mucous membrane and skin irritation noted by cranemen and pitmen. Recommendations include use of low silica containing sand, good housekeeping, better exhaust ventilation, regular wetting of foundry sand with water, mechanizing the shake out procedures, use of breathing apparatus, long sleeve shirts and gloves by cranemen, and repairing the seal on the crane cabs.

Concentrations of wood dust in the woodworking shop are believed to be capable of producing transient irritation of the respiratory tract. Exposures to fumes of copper (7440508), tin (7440315), and zinc (7440666) in the metals casting area were determined to be nontoxic. Recommendation are made for the improvement and control of the hazards.

The survey was prompted by a request from the employer regarding employee exposure to a variety of dusts, fumes and vapors. Measurements of workplace concentrations of airborne chemicals, evaluation of process operations and control measures, medical interviews, and a review of the pertinent literature led to the conclusion that exposures of employees to ammonia (7664417), beryllium (7440417), chromic-acid (7738945), lead (7439921), methyl- ethyl-ketone (78933), fumes, nitric-acid (7697372), nuisance dusts, oil mist, sodium-hydroxide (1310732), toluene-diisocyanate (1321386), 1,1,1-trichloroethane (71556), 1,1,2-trichloro-1,2,2- trifluoroethane (354585), welding fumes, mahogany wood dust and wood dust, and operations in the print shop, dark room and lapping were not toxic to employees. Employee exposure to free silica (7631869) at the vacu-blast operation was potentially toxic. Recommendations are made to reduce the dermatitis experienced by employees in some departments.

The survey was prompted by a request from a representative of 125 affected employees, alleging exposure of workers to excessive dusts, mists and a variety of chemicals and solvents, as well as medical illness, early retirement and death from cardiovascular disease due to occupational exposure. Medical and environmental data failed to show the presence of toxic concentrations of chemicals and dusts in the ball milling and solvent based coating operations, although a potential health hazard due to exposure to silica (7631869) may exist during the preparation of the coating solutions. Nuisance dust did not present a health hazard in the converting departments, while a potential hazard from exposure to silica may exist in the building that serves as a warehouse for a wide variety of substances. Cross- sectional analysis of employee medical records indicated that the possibility exists that an excess number of cases of cardiovascular diseases have occurred at GAF.

(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... (Click to show more)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 (7631869). 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.

Personal and area air sampling was conducted for free silica (7631869), formaldehyde (50000), phenol (108952), dimethylethylamine (75649) (DMEA), and methylene-bisphenyl- isocyanate (101688) (MDI). Medical histories of 34 workers were obtained by interview. Some physical examinations and clinical tests also were conducted. All but two MDI air samples were below the threshold limit value (TLV) of 0.2 milligrams per cubic meter (mg/m3); concentrations in excess of the TLV were found at a coreblow machine operator site and for an assistant engineer. Three free silica samples were in excess of the 50 micrograms per cubic meter NIOSH standard. All DMEA samples were below 8 parts per million. Formaldehyde and phenol were not found at toxic concentrations. The symptoms reported included mucous membrane, eye, ear, nose, throat, sinus, and skin irritations and respiratory difficulties. Eight workers reported acute nausea, sore throat, headache, and nose blockage. The author concludes that workers at this company are not exposed to toxic chemical concentrations. Recommendations are made to maintain minimum DMEA and free silica concentrations by improving two local exhaust systems, improving air exchange rates, providing protective clothing, and instituting other cleaning procedures. Medical surveillance programs should include histories, chest x-rays, pulmonary function tests, and general physical assessments.

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.

The evaluation was requested by an authorized employee representative on behalf of the approximately 750 affected employees. Airborne concentrations of fibrous glass and dried binder dust, phenol (108952), formaldehyde (50000), and ammonia (7664417) vapors were determined to be below their respective evaluation criteria in all areas examined. The airborne concentration of free silica (7631869) was 79 micrograms per cubic meter. The author concludes that concentrations of airborne contaminants are not hazardous to employees under the conditions observed, but the exposure of the paint mixing operator in the chemical factory to airborne free silica may pose a potential hazard.
