The workforce included 63 production workers and 33 administrative personnel. Employee exposures to metals and dusts, including 28 elements of toxicological importance, were evaluated during an industrial hygiene survey involving personal and general air sampling. Each of the 11 air samples showed aluminum (7429905), molybdenum (7439987), and nickel, while some showed calcium (7440702), cobalt (7440484), copper (7440508), iron (7439896), magnesium (7439954), and zinc (7440666). The only metal exceeding NIOSH Recommended Exposure Limit (REL) was nickel, ranging from below the American Conference of Governmental Industrial Hygienists threshold limit value of 10mg/m3 for nuisance dusts, ranging from these as nuisance dusts and further reduction in amounts should be made. The author recommends that care be taken to ensure good working order of mullers to prevent leaks. Generation of nickel dusts in impregnation area should be better controlled. A regular housekeeping schedule should be started for vacuum removal of accumulated dust from work areas. Appropriate respirators should be worn in muller room and impregnation and product load out areas.

(1987) Artistic Awards, Colorado Springs, Colorado. (Click to open report) In response to a request from Artistic Awards Co. (SIC-3499), Colorado Springs, Colorado, a study was made of possible exposure to lead (7439921) during lead medallion production. An elevated blood lead level had been found in one worker with symptoms of weakness and fatigue. Personal breathing zone air samples obtained from the areas of casting and engraving showed levels of 7.3 to 8.0 micrograms/cubic meter (microg/m3).

(SIC-3499), Colorado Springs, Colorado, a study was made of possible exposure to lead (7439921) during lead medallion production. An elevated blood lead level had been found in one worker with symptoms of weakness and fatigue. Personal breathing zone air samples obtained from the areas of casting and engraving showed levels of 7.3 to 8.0 micrograms/cubic meter (microg/m3). Samples collected during grinding and buffing of lead medallions indicated lead concentration in the breathing zone of 1300 to 1900microg/m3. Each of four grinding and buffing stations was fitted with a well enclosed ventilation hood. At one station, the ductwork was clogged with buffing wheel material and ducts at the other three stations were disconnected inside the cabinets. Excessive levels of lead in the air resulted from a lack of local exhaust ventilation in this area. Workers in this room wore half face respirators; however, the respirator which was worn by the worker who had the elevated blood lead level failed to pass a fit test. After improvements had been made, the ventilation system was observed to be very effective. Lead exposures during buffing and grinding operations had been reduced to below the limit of detection, 6microg/m3. The author concludes that one worker has been overexposed to lead due to a poorly fitted respirator, and possibly to ingestion of lead deposited on food or drinks.

F. Goodrich tire manufacturing facility (SIC-3011) located in Woodburn, Indiana. Excesses were reported in the milling and tuber areas of the facility. Company medical records, death certificates, and medical records from private physicians or hospitals were used to obtain data. Five cases of lung cancer and one of leukemia were confirmed. Analysis revealed a ten fold increase in lung cancer incidence over the expected number. In a survey made 5 years previously, breathing zone samples were taken for nitrosamines, for which NIOSH recommends keeping exposure as low as possible. Exposures to N-nitrosomorpholine (59892) ranged from 0.5 to 1.8 micrograms per cubic meter (microg/m3) and exposures to N- nitrosodimethylamine (62759) ranged up to 0.09microg/m3. Exposures to benzene (71432) in 1975 ranged from 0.5 to 11.9 parts per million. Measurements taken since 1980 showed significantly lower levels. Also, prior to 1979, talc (14807966) was used at this facility, suggesting possible exposure to asbestos (1332214). The authors conclude that based on lung cancer latency, there is evidence of exposure to an etiologic agent in the milling and tuber area of this company. It is recommended that exposures to various contaminants be kept under control and that a medical surveillance program be implemented.

These employees were exposed to soybean dusts as raw dust, cleaner dust, extracted dust, or mixed dust. For 34 workers, the range of total raw dust exposure was 0.16 to 22.6mg/m3. One employee performing a cleanup operation in the head house was exposed to nuisance dust at 14.7mg/m3, near the Occupational Safety and Health Administration permissible exposure limit of 15mg/m3. Another worker was exposed to 22.6mg/m3 during a similar operation. At the time of study, use of personal respiratory protective equipment was by worker discretion. For workers exposed to raw dust, respirable dust ranged from 0.02 to 1.02mg/m3, with employees in the bean barge cleanup area and head house utility workers having the highest exposures. Exposures to cleaner soybean dust ranged from 0.18 to 0.72mg/m3. A high prevalence of lower respiratory symptoms was found, correlating with dust exposure, particularly raw soybean dust. Occupational asthma could not be confirmed or ruled out. It is recommended that engineering controls be installed in soybean receiving and shipping areas. Local exhaust ventilation and enclosing of specific areas are also highlighted. The authors recommend that use of respiratory protective gear be more actively pursued.

No exposure to butyl-cellosolve was detected among liquid coaters and no epichlorohydrin was detected in the process area air samples. No exposure to nickel or chromium was detected among mechanical grinding spirallers. One laser spiraller was exposed to 8 micrograms/cubic meter (microg/m3) of nickel and 8microg/m3 chromium. Trace amounts of nickel were noted in the breathing zones of one plating lab worker and one calibrator. Total particulate exposures ranged from 0.1 to 0.9mg/m3. The author concludes that there were no known overexposures to contaminants at this facility. The author recommends that the exhaust ducts and fan be checked to find the cause for decreased mixing room ventilation system performance noted at the time of the study. Mixing room workers should ensure that all materials are handled as closely as possible to the local exhaust hoods. Standard written operation procedures for use of respirators should be developed.

The production facility formulates about 400 specialty chemical products for institutional and industrial applications. Personal sampling results included the following: sodium-hydroxide (1310732) dust, from nondetectable to 0.63mg/m3; hydrochloric-acid (7647010), nondetectable to 0.05mg/m3; phosphoric- acid (7664382), nondetectable; methylene-chloride (75092), 6.6 to 380mg/m3; and toluene (108883) 0.6 to 45mg/m3. Full shift noise exposures ranged from 78 to 88 decibels-A (dB-A) with a mean of 82dB- A time weighted average. Noise exposures over the NIOSH recommended exposure limit of 85dB-A existed for 5 workers. The author concludes that a health hazard existed from exposures to methylene- chloride. Individual noise exposures at or in excess of the OSHA permissible exposure limit were possible. The author recommends substituting a less toxic chemical for methylene-chloride and improving ventilation conditions. The use of personal protective equipment should be upgraded and the reuse of gloves stopped. The development of a hearing conservation program is suggested.

(1987) Eccles Saw and Tool Company, Cincinnati, Ohio. (Click to open report) In response to an employee request, an evaluation was made of metal dust exposures from the process of sharpening saw blades and tools at the the Eccles Saw and Tool Company (SIC-3541), Cincinnati, Ohio. In two personal air samples, the following concentrations were determined: cobalt (7440484), 26 and 63 micrograms/cubic meter (microg/m3); tungsten (7440337), 365 and 925microg/m3; nickel (7440020), 3.9 and 9.3microg/m3; cadmium (7440439), less than 2microg/m3; and silver (7440224), less than 2m...

In two personal air samples, the following concentrations were determined: cobalt (7440484), 26 and 63 micrograms/cubic meter (microg/m3); tungsten (7440337), 365 and 925microg/m3; nickel (7440020), 3.9 and 9.3microg/m3; cadmium (7440439), less than 2microg/m3; and silver (7440224), less than 2microg/m3. Air containing cobalt at 30microg/m3 and nickel at 7microg/m3 was being discharged back into the workspace from the recirculated local exhaust ventilation air. A medical evaluation was performed on three workers; all three reported coughing four to six times a day, four or more days per week, with occasional episodes of wheezing. Two of these employees were grinders, having been working at this company for 15 and 85 months, while the other was a truck driver, who spent about 3 hours per day in the shop, but did no grinding. Appreciably higher cobalt levels were noted in the urine of a worker exposed to cobalt at 63microg/m3 than in office workers. The authors conclude that at least one worker was exposed to an excessive cobalt concentration. The authors recommend general improvements in the housekeeping practices in the grinding shop, modification of the present local exhaust ventilation system, preplacement and periodic medical examinations of employees, and limiting exposure to cobalt.

Several surface samples revealed chrysotile (12001295) and amosite (12172735) fibers which indicated a history of past airborne asbestos at the site. Of the various air samples taken, only one showed airborne asbestos fibers to be present. This sample contained 0.005 fibers per cubic centimeter (NIOSH guideline, 0.01 fibers per cubic centimeter). Asbestos containing fireproofing (1 to 7 percent chrysotile) was present in the building and was friable, had some water damage, was exposed in the return air plenum, and could be reached through ceiling tiles. The author concludes that a potential health hazard exists. It is recommended that the material be safely removed by a reliable contractor skilled in asbestos abatement. Interim precautionary measures are suggested to allow for building use until the asbestos is completely removed. These include isolating the fireproofing from the supply air source, using only wet janitorial techniques to prevent redispersion of settled dusts, establishing a monitoring system for the facility, designing maintenance procedures which minimize the potential for asbestos exposure, and educating employees as to the nature of the hazard.

Over half of all workers (about 70) reported watery itchy eyes, sneezing, or runny stuffy noses. Symptoms of skin rashes, cough, chest tightness, and shortness of breath were also reported throughout the facility. Dust concentrations were highest in the composition area, where all workers experienced irritation of eyes, nose, and throat, and a few developed occupational asthma confirmed by company physicians. Workers were exposed to several vitamin products which were irritating to eyes and nasal and respiratory mucosa because of acidity. Some workers became hypersensitive to dusts due to protein and polysaccharide contents. Most samples showed total and respirable dust measurements well below Occupational Safety and Health Administration permissible exposure limits for nuisance dusts. However, these are not common nuisance dust components. The authors suggest that the limits provide little protection for average workers exposed to such dusts. Asbestos sampling revealed potential hazard from falling insulation. Recommendations pertaining to local exhaust hoods, amended work practices, use of personal dust respirators, avoidance of skin contact, and proper ceiling insulation are offered.

No nitrosamines were detected. Cobalt levels were nondetectable to 26.8 micrograms/cubic meter (microg/m3) (American Conference of Governmental Industrial Hygienists Threshold Limit Value, 50microg/m3). Tungsten levels were nondetectable to 0.41mg/m3 (NIOSH Recommended Exposure Limit, 5mg/m3). Medical survey of 35 workers showed respiratory symptoms associated with length of employment and smoking status. Symptoms did not correlate with exposure category. Personal air samples were taken for cobalt for ten workers giving urine samples pre and post shift. All had increased urine cobalt levels over shift. There was no correlation between total airborne and urine cobalt levels, but there was a significant association for post shift urinary and respirable cobalt. The authors recommend that air sampling for tungsten- carbide and cobalt be continued. Good housekeeping and personal hygiene practices should be instituted and maintained. Change to a safer cutting fluid is recommended along with a medical surveillance program and careful follow up of employees with persistent symptoms of cough, chest tightness, shortness of breath, or wheezing.
