Workers were experiencing lightheadedness, shortness of breath, fainting, lung problems, and skin rashes. For 86 air samples taken, respirable crystalline silica (14808607) personal exposures averaged 0.12mg/m3 (NIOSH Recommended Exposure Limit (REL) for respirable crystalline silica, the slip houses exceeded the NIOSH REL. The 18 samples taken in the casting area indicated that the average exposure limit was finishing area 18 samples showed an average respirable silica concentration of 0.11mg/mg3. Exposure to talc (14807966) averaged 2.7mg/m3 in the casting areas for 38 samples. Symptoms of chronic cough were noted in 20 percent, chronic bronchitis in 5 percent, and shortness of breath in 31 percent of the workers. Of 196 chest x- rays examined, 18 exhibited evidence of asbestos (1332214) or talc exposure; five had symptoms of silicosis. The authors conclude that there is a serious, extensive problem regarding exposures to respirable silica and respirable talc dust. The authors recommend specific improvements in respirator policy, materials handling systems, air cleaning devices, local exhaust systems, housekeeping, medical examinations and record keeping.

Concern was expressed over exposure to aluminum (7429905) dross dust and ammonia (7664417) vapors in the dross mill, cast house, and furnace building. The raw materials used at the firm consisted of about 80 percent aluminum dross and 20 percent scrap aluminum metal. Analyses were made of a bulk sample of dross, personal breathing zone air, and area air. Ammonia vapors were present in potentially harmful quantities. Airborne concentrations of total dust, respirable dust, and respirable silica (7631869) dust exceeded NIOSH recommended exposure limits or OSHA permissible exposure limits. A self administered questionnaire was used to investigate symptoms in 12 workers from the dross mill and 12 workers from the rolling mill. Respiratory symptoms were not more common among dross mill workers than rolling mill workers. The authors conclude that workers were exposed to potentially hazardous levels of dust and ammonia vapor. The authors recommend specific measures to reduce dust concentration, control employee exposures to metal fumes, control noise exposures, and inform workers of the hazards of their jobs. Good housekeeping and work practices should be encouraged. Open topped spaces such as pits should be treated as confined spaces.

The company produced steel in electric arc furnaces. Workers in the vicinity of the electric arc furnace had complained of bad odors and tastes, and respiratory irritation. Breathing zone and general room air samples were tested for sulfur-dioxide (7446095), arsenic (7440382), cadmium (7440439), lead (7439921), total particulate, and crystalline silica (quartz (14808607) and cristobalite (14464461)). Seven general area sample measurements ranged from 0.2 to 1.7mg/m3 for sulfur-dioxide. One breathing zone sample registered 0.78mg/m3. Arsenic was found in one sample at a level of 0.02mg/m3. Cadmium was found in one of 11 samples at 0.006mg/m3. Lead was present in all 11 samples ranging from 0.004 to 0.3mg/m3. Total dust measurements were 14 and 12mg/m3. Respirable dust samples contained 1.5 and 1.4mg/m3 respirable dust; free silica samples were 0.5 and 0.2mg/m3 (quartz). The author concludes that a potential health hazard existed from exposure to arsenic, cadmium, lead, and crystalline silica. The author recommends that specific improvements be made in respiratory protection, and that workers be notified when sulfur compounds are being added to the steel.

Concerns were specifically expressed about the handling and burning of refuse derived fuel (RDF), asbestos (1332214) insulation, coal dust, fly ash, hot working environments, polychlorinated-biphenyl (1336363) (PCB) present in grounding transformers, and on site chemical usage and storage. RDF was composed primarily of the shredded combustible part of municipal solid waste. A survey of the facility indicated that potential hazards did exist from noise, heat, asbestos, coal dust, and crystalline silica (14808607). The only documented case of over exposure was to coal dust in the coal yard. Metal exposure was very low or non detectable. The author concludes that hazards existed due to heat levels, noise, potential asbestos exposure, and elevated coal dust and silica exposures. The author recommends work schedule modifications to reduce heat stress, improved storage methods for chemicals, improvements in the respiratory protection program, a hearing conservation program, monitoring workers for trace metal exposures, asbestos cleanup or monitoring, employee education regarding possible hazards, and medical surveillance.

(SIC-3565, SIC-3321), Westfield, Massachusetts, due to concern over symptoms of breathing difficulties experienced by workers. Workers at the foundry were involved in coremaking, mold making, casting, shake out, and knockout operations. Possible exposures to carbon-monoxide (630080) (CO), respirable free silica (14808607), dimethylethylamine (75649) (DMEA), and acrolein (107028) were determined. Acrolein was not detected. CO levels ranged from 10.4mg/m3. The respirable free silica ranged up to 0.54mg/m3. Pulmonary function tests and x-rays showed no evidence of silicotic lung disease. The authors conclude that a health hazard existed due to worker exposures to respirable free silica, DMEA and CO. The authors recommend measures to reduce worker exposures, including a mandatory personal protective equipment policy, administrative and engineering controls for CO, improvements in ventilation, and periodic medical examinations.

This foundry was engaged in the manufacture of a variety of aluminum automotive and commercial mold castings. Work practices and conditions of exposure were observed during a walk through survey. Employee medical interviews were conducted, and medical records were reviewed. OSHA air monitoring data were reviewed. Transient symptoms of upper respiratory irritation were reported by molders; these were related to the use of spray release compounds. Sawmen and hot inspectors did not report respiratory symptoms. No objective evidence was found of chronic respiratory illness or metal fume fever in this study population. Heat intolerance was reported by two molders. Air monitoring data indicated no overexposures. The authors conclude that no evidence of chronic respiratory illness could be documented, although acute respiratory irritation appeared common. The authors recommend that proper work practices be followed and all appropriate protective equipment be worn by the employees. Period checks of the ventilation controls are suggested.

This facility was engaged in the wet milling of corn and production of food products such as fructose, corn oil, corn germ and corn starch. Overexposure to epichlorohydrin (106898) was deemed unlikely. However, respiratory protection and protective gloves should be worn when working around this substance. Acid exposures occurred only in refining areas. Sulfuric-acid (7664939) and phosphoric-acid (7664382) exposures were of concern due to the high concentrations used. Sulfur-dioxide (7446095) exceeded the NIOSH evaluation criteria of 1.3mg/m3 in 11 of 13 general room air samples. One worker out of seven monitored for total particulate and free crystalline silica (14808607) was overexposed to quartz. The author concludes that a health hazard existed from exposures to crystalline silica, epichlorohydrin, sulfuric-acid, and sulfur- dioxide. Although five cases of multiple sclerosis were noted among current and former workers, there had been no known occupational etiology for this disease and no known connection between the disease and chemicals or working conditions at this site. The author recommends that engineering controls and respiratory protection should be used to reduce exposures.

Specific concern had been expressed regarding exposures to silica (7631869), coke, and asbestos (1332214). Of 108 persons participating in the study, 91 had worked at the elemental phosphorus facility (EP). Small, irregular interstitial pulmonary opacities were noted in two participants, and two others had pleural plaque. Of 88 participants who had ten or more years in the phosphate industry, the 36 workers with ten or more years in the EP facility were no more likely to have chronic cough, shortness of breath, abnormal lung sounds on physical examination, pulmonary function impairment, or x-ray signs of fibrogenic dust exposure than those with less than 10 years exposure. Those working longer than 10 years in the EP facility had numerically higher prevalence of chronic bronchitis and chronic wheeze, but the differences were not statistically significant. The author concludes that no association between health and time at the EP facility could be discerned from the available data, although it is possible that the study participants were not representative of all former facility workers.

Simplot Company (SIC-2874), Pocatello, Idaho, concerning exposures to acid mists, ammonia (7664417), fluorides, nitrogen- dioxide (10102440) (NO2), free silica (7631869), and sulfur-dioxide (7446095) (SO2). There were about 600 workers at the facility. A medical and occupational history questionnaire completed by 74 men indicated that 30 percent had eye or upper respiratory complaints at least 1 to 2 days/week, and 17 percent had such complaints on most days. No relationship was found between chronic cough, chronic bronchitis or shortness of breath and length of employment. Chest x- rays of 40 workers did not reveal signs of pneumoconiosis. Some samples for ammonia, hydrogen-fluoride (7664393), phosphoric-acid (7664382), sulfuric-acid (7664939), and SO2 exceeded the respective NIOSH recommended exposure limits (REL). The REL for free silica was also exceeded, but exposed workers wore respirators. The authors conclude that workers are overexposed to ammonia, hydrogen- fluoride, phosphoric-acid, sulfuric-acid, silica, and SO2. The authors recommend that exposures to hazardous vapors, acid mists and particulates be reduced through application of engineering controls, respiratory protection, and monitoring. Medical evaluations should be conducted for workers using respirators and workers exposed to silica.

Concern was voiced over silica (7631869) dust exposures for highway drill crews during overburden drilling. To reduce operator exposure during this process an enclosed cab was provided for the operator, a rubber skirt was suspended from the deck of the drill to contain the dust, and a collection system conveyed the dust to the ground away from the operator. Respiratory protection was also provided. In hot weather, windows of the cab were left open and respiratory protective devices were seldom used. Quartz (14808607) was the only form of crystalline silica identified. Personal breathing zone samples indicated a time weighted average respirable 8 hour dust exposure of 0.8mg/m3 which exceeded the NIOSH recommended standard of 0.05mg/m3. The mass of airborne dust particles that were 10 micrometer in aerodynamic diameter and below were approximately 69 percent inside the cab and 45 percent outside the cab. The cab did afford about a 76 percent reduction in respirable dust exposure for the operator. The author concludes that a respiratory health hazard did exist for the drill crew. Engineering controls instituted after this survey resulted in reduction in dust levels.
