(SIC-3291) facility in Alliance, Ohio. Sancap Abrasives manufactured coated abrasives (sand paper), and had previously discontinued use of abrasives containing silica. The survey found 8 hour time weighted average (TWA) exposures of respirable particulate concentrations for 20 samples ranging from 0.09 to 0.79mg/m3. Total particulate concentrations ranged from 0.29 to 4.58mg/m3. Results of 20 personal air samples for aluminum (7429905) concentrations ranged from less than detectable to 0.02mg/m3. The amounts of free silica in all personal air samples were below the limit of detection. The amounts of quartz (14808607) and cristobalite (14464461) in two bulk samples of aluminum-oxide were also below the detection limits. No neurotoxic agents were identified at the facility. The authors conclude that silica exposures were not sufficient to pose a serious risk of silicosis. Annual medical examinations were recommended for all workers working in the coated abrasives division for a total of at least 10 years when silica was used.

Exposure levels detected for 1,1,1-trichloroethane (71556) ranged from 0.32 to 0.63 parts per million (ppm); vinylidene-chloride (75354), not detectable; formaldehyde (50000), below detectable levels; hexamethylenetetramine (100970), detected in only one of five samples at a concentration of 0.044ppm; ammonia (7664417) from 2 to 35ppm; phenol (108952), below the limit of detection; carbon- monoxide (630080), less than 1 to 4ppm; total particulates from 2.26 to 13.78mg/m3; asbestos (1332214), no detectable levels; and toluene- diisocyanate (584849) from nondetectable to 0.0036ppm. The author concludes that there was a potential for overexposure to nuisance particulate in one area of the facility. The author recommends that increased emphasis be placed on reducing dust exposures through proper work practices and engineering controls. Local exhaust ventilation should be completed in the Hot Oil Press Department. Further study is suggested to pinpoint the source of the toluene- diisocyanate in the coating department. Immediate reporting of all incidences of dermatitis or other health problems is encouraged.

Sixteen breathing zone and general room air samples were collected with lead concentrations ranging from not detectable to 0.08mg/m3. Three of these readings exceeded the evaluation criteria of action level for lead. Methylene-chloride (75092) was found in small quantities in 13 of 14 air samples. The highest level of methylene-chloride detected was 15.7mg/m3. No workers from the grinding room showed blood lead levels above 40 micrograms/deciliter. No evidence of lead toxicity was noted in workers from the blood samples or from discussions held with the workers. The author concludes that a potential health hazard from lead existed at the time of the evaluation. The author recommends that care be taken to reduce lead exposure in the grinding room. No dry grinding or polishing of the leaded glass should be permitted. The down draft ventilation in the grinding stations should be maintained, cleaned, and balanced so that each work station has sufficient capture velocity.

The terminals belonged to the Jones Truck Lines, the P.J. Hamill Transfer Company, and the Overnight Transportation Company. During the 1970s these terminals were sprayed with waste oil for dust control. A self selected group of workers participated in a medical survey and provided information regarding employment and TCDD exposure history. A significant association was noted between symptoms of numbness in hands and feet, pins and needles in the extremities, insomnia and feelings of depression, and possible exposure to TCDD. One case of porphyria cutanea tarda and one of dermatofibrosarcoma were reported. The patient with porphyria cutanea tarda later developed a pelvic angiosarcoma, probably of soft tissue origin. Environmental samples taken at Jones Truck Lines revealed a dioxin concentration of about 18.7 parts per billion on the rafters inside the terminal. Dioxin was present in two surface soil samples taken near an entrance gate. The authors conclude that no definite association between TCDD exposure and symptoms or medical problems can be established. The authors recommended that measures be taken to control or eliminate possible exposures at the terminals; action was taken based on these recommendations.

Crystalline silica (7631869) concentrations in the breathing zone of sand molders, core makers, sand mixers, and core knockout personnel ranged from 52 to 238 micrograms/cubic meter (microg/m3). Formaldehyde (50000) levels of 0.11 to 0.42mg/m3 were found in the breathing zones of coremakers, metal pourers and core knockout personnel, contributing to eye and upper respiratory tract irritation. Triethylamine (121448) was found at levels of 0.4 to 38mg/m3 in the breathing zone of coremakers, increasing respiratory distress. No excess levels were found of aluminum, magnesium, beryllium, inorganic fluorides, barium, methylene-bisphenyl-isocyanate, 1,1,1-trichloroethane, ethyl- alcohol, or ozone. The authors conclude that workers were exposed to potentially toxic concentrations of crystalline silica and formaldehyde. Workers were also experiencing eye and respiratory irritant exposures. The authors recommend the institution of an effective medical and environmental monitoring program, control of free silica dust exposure through engineering methods, medical examinations for workers with possible exposure to silica, and fit testing respirators.

Exposures occurred during the manufacturing of diamond studded and diamond impregnated cutting tools. Employees registered complaints of gastrointestinal, neurological, cardiovascular, and respiratory problems along with skin rashes and a metallic taste in their mouths. Four of the 37 air samples collected showed cobalt (7440484) levels exceeding the 0.1mg/m3 limit established by OSHA. Most of the handling of loose cobalt containing powders occurred in the production areas. Six samples revealed the presence of nickel (7440020), three of which exceeded the 0.015mg/m3 NIOSH recommended limit. Excessive graphite (7782425) levels were detected in the carbon room with two of three personal exposure samples registering above 10mg/m3. A questionnaire, preshift and postshift pulmonary function tests, and chest x-rays were administered to workers. No evidence of hard metal disease or mixed dust pneumoconiosis was found. The authors conclude that there is a hazard from exposure to cobalt, nickel, and graphite dust. The authors recommend measures to reduce and monitor worker exposures to cobalt and to establish a medical monitoring program for all cobalt exposed workers.

(1986) (revised), National Starch, Indianapolis, Indiana. (Click to open report) A request for an investigation of pulmonary and cardiovascular disease was received from the National Starch and Chemical Corporation (SIC-2046), Indianapolis, Indiana. In a survey in March 1985, concentrations of hydrochloric-acid (7647010), sulfuric-acid (7664939), sodium-hydroxide (7646697), propylene-oxide (75569), and total and respirable starch dust were all below acceptable limits.

In a survey in March 1985, concentrations of hydrochloric-acid (7647010), sulfuric-acid (7664939), sodium-hydroxide (7646697), propylene-oxide (75569), and total and respirable starch dust were all below acceptable limits. In the Wet Mill, samples were taken of sulfur-dioxide (7446095) (SO2) which indicated exposure levels ranging from 1.7 to 2.4 parts per million, in excess of the NIOSH recommended exposure limit (REL) of 0.5ppm. Personal area breathing samples for SO2 showed levels of 1.8 to 2.5ppm in October 1985. Upper respiratory irritation occurred in some employees, presumably due to SO2 exposure. The authors conclude that workers at this facility were exposed to sulfur-dioxide concentrations in excess of the NIOSH REL. Recommendations by the authors include installation of effective engineering controls, improved employee work practices, and the use of respiratory protection to decrease SO2 exposure to within acceptable levels. Airborne concentrations of starch should be controlled through proper maintenance of equipment and good housekeeping practices. Comprehensive, annual medical examinations are recommended for all employees exposed to S02.

Sugar processing operations involved approximately 375 workers, and maintenance included about 175 of these workers. During beet processing, personal breathing zone and general air samples were collected and analyzed for several chemicals and total and respirable particulates of various dusts. Welding fumes were analyzed by inductively coupled plasma/atomic emission spectroscopy of personal filter samples. The following exposures were considered excessive by the most stringent criteria: lime kiln helper to total particulates (9.6 and 11.2mg/m3), Weibul storage bin housekeeper to sugar dust (13.4mg/m3), diffuser operator and charger to formaldehyde (50000) (0.05 to 0.09mg/m3), and welders and cutters to total welding fumes (2.3 to 84mg/m3) and specific metals, particularly hexavalent chromium (18540299) (0.003 to air and settled dust samples contained crystalline silica (14808607), representing a potential hazard. Recommendations include improved particulate containment and ventilation, use of respirators where appropriate, and formaldehyde replacement.

Sugar processing operations involved approximately 370 workers, and welding potentially exposed ten to 15 workers. Personal and general air samples were collected and analyzed for several chemicals, total and respirable dusts, and metals and welding fumes. Methods included gravimetric analysis, chromatography, spectroscopy, and X-ray diffraction. Exposures in excess of the most stringent criteria were found for calcium-oxide (1305788), coal dust, crystalline silica (14808607), sugar dust, and formaldehyde (50000). Areas of greatest exposure included lime kiln operation, coal handling, and storage bin housekeeping. The latter was only an area of potential exposure, since workers wore dust respirators. Detectable formaldehyde levels in general air represented a possible carcinogenic risk. Presence of silica in bulk samples presented a potential risk of silicosis. Exposures to total welding fumes and metals exceeded stringent criteria in two thirds of samples. Potential cancer risks included hexavalent chromium (18540299) and nickel (7440020). Recommendations include use of respiratory protection, dust and fume containment, and formaldehyde replacement.

Beet processing involved 680 workers, and welding exposed a potential ten to 15 workers to metal fumes. Personal and general air samples were analyzed for chemicals and total and respirable dusts, and total welding fumes and metals were analyzed from personal samples. Analytical methods included chromatography, spectroscopy, X-ray diffraction, and gravimetry. Exposures in excess of the most stringent criteria were found for calcium-oxide (1305788) and calcium-carbonate (471341) in lime kiln workers, sugar dust in sugar bin workers, insoluble hexavalent chromium (18540299) and nickel (7440020) during welding, total welding fumes in one case, and nickel during a metal coating spray process. Quartz (14808607) was found in several settled dust samples and high volume air samples. Nickel and chromium exposures presented potential cancer risks. The authors conclude that workers were overexposed to calcium-oxide, calcium-carbonate, sugar dust, total welding fumes, hexavalent chromium and nickel at this facility. Recommendations include particulate containment, ventilation, and respiratory protection where appropriate.
