The facility was a gray and ductile iron foundry with 55 workers on three shifts. Personal breathing zone concentrations of respirable silica (14808607) ranged from 31 to 284 micrograms per cubic meter (microg/m3) as time weighted averages (TWAs). Of the 16 nearly full shift samples taken, six exceeded the OSHA Permissible Exposure Limit of 100microg/m3. Benzene (71432S) was detected in one sample for a molder at 0.1 parts per million (ppm), equal to the NIOSH recommended limits. Formaldehyde (50000) concentrations in the area ranged from 0.012 to 0.026ppm. Carbon-monoxide (630080) concentrations ranged from 2 to 30ppm with five of the ten personal breathing zone samples exceeding the accepted levels. Phenol (108952) at 0.07 to 0.54ppm, isopropanol (67630) at 1 to 38ppm, toluene (108883) at less than 0.062 to 0.066ppm, and the metals aluminum (7429905), chromium (7440473), copper (7440508), iron (7439896), magnesium (7439954), manganese (7439965), lead (7439921), and zinc (7440666), did not exceed the recommended limits. The authors conclude that there was a hazard from respirable silica, carbon-monoxide, formaldehyde, and benzene exposures in the coremaking, molding, and shakeout areas. The authors recommend that engineering controls, an improved respiratory protection program, and improved work practices be implemented to reduce exposures.

Worker exposure to carbon-monoxide (630080), noise and paper dust were also of concern. The company was a book bindery, a three story complex employing about 115 workers in the office and 235 in the production of the books. Printing was done off site. Six varieties of hot melt glues were used in nine machines on three floors to produce 100,000 hard cover and 25,000 paperback books daily. None of the measurements taken for total airborne particulate, carbon-monoxide, 1,1,1-trichloroethane (71556) and general aldehydes exceeded the recommended limits. Exposures were above recommended limits (lowest feasible level) for acetaldehyde (75070) and formaldehyde (50000). Workers were potentially exposed to noise levels in excess of the OSHA Action Level of 85 decibels-A. Symptoms of upper respiratory irritation were noted in some of the ten employee medical records reviewed. Numerous complaints of repetitive motion trauma were seen in OSHA logs. The authors conclude that there was a potential hazard from acetaldehyde and formaldehyde exposures. The authors recommend that exposures be controlled to the lowest feasible level. Work practices and engineering controls throughout the facility should be improved.

Of particular concern was the possibility that chronic respiratory diseases were related to smoke containing biogenic silica fibers (BSF). BSF exposure was evaluated and a case/control study of mesothelioma and BSF exposure was pursued using records from the Hawaii Tumor Registry to identify subjects. Exposure to BSF was recorded for equipment operators involved in moving sugarcane into the mill. The air concentrations of inorganic fibers ranged from 1,200 to 8,350 fibers/cubic meter (f/m3). Rake operators had the highest exposure of field workers, ranging from 1,250 to 56,280f/m3. Asbestos (1332214) was detected in air samples from machinists, mechanics and operators of planting machinery with the highest concentration being 0.77f/cubic centimeter. In the medical study of 355 sugarcane workers, neither respiratory symptoms or chest X-ray abnormalities were associated with BSF exposure. The authors conclude that no association was found between occupational exposure to BSF and respiratory symptoms, X-ray signs of chronic lung disease or mesothelioma. At the time of the survey, mill workers were exposed to asbestos. The authors recommend measures to decrease the exposure to asbestos at these sites.

Workers were also concerned about possible exposures occurring during recoating of steel with a two part epoxy resin paint. Personal breathing zone air samples were collected during cutting procedures conducted with either a cutting torch or a cut off saw, and analyzed for total particulates, metals, oxides of nitrogen, aldehydes, 4,4-methylene-dianiline (101779), volatile organic compounds and carbon-monoxide (630080). Sampling for methyl- isobutyl-ketone (141797), xylene (1330207), and 2-butoxyethanol (111762) was conducted during the patch kit operations. The authors conclude that no exposures related to the epoxy resin coating or the patch kit were detected which would be of concern. Over exposures were documented to total particulates and various metals including iron (7439896), nickel (7440020), copper (7440508), titanium (7440326), and arsenic (7440382). These exposures most likely came from the reinforcing rod and the cutting wheel. The authors recommend that measures be taken to reduce these exposures while cutting either coated or uncoated steel.

(SIC- 3823), Statesville, North Carolina. The company employed 42 workers, including 17 directly involved in manufacturing temperature measurement devices for industrial applications. Processes evaluated at this site during the on site visit included tungsten inert gas welding (TIG), metal grinding, buffing and sanding, brazing and soldering, and degreasing. Observations included sporadic adherence to the use of personal protective equipment and the lack of a formal safety program. Shop vacuums were used to ventilate the grinders and tubing cutters and did not appear to effectively contain the dusts after collection. Air sampling results indicated that contaminant levels were below NIOSH recommended exposure limits. Low concentrations of metals, both fumes and dust, were detected at several workstations. The author concludes that workers were not exposed to airborne contaminants above recommended limits at the time of the survey. The shop vacuums used as local exhaust systems were not intended for this use. The author recommends specific measures to improve the level of safety and health, including ventilation and employee training.

A walk through survey, and medical and environmental evaluations were conducted at the mine and mill. Airborne particulate samples were collected and subsequently analyzed for solvent soluble portions. Six samples had concentrations of particulates ranging from 0.1 to 0.17mg/m3. Three samples of sub micron size particulates ranged from 0.20 to 0.27mg/m3. Seven full shift personal nitrogen-dioxide (10102440) samples ranged from 0.47 to 1.4 parts per million (ppm) with a mean exposure of 0.8ppm. Airborne asbestos was not detected in 15 airborne samples collected in the mill area. The prevalence of chronic cough and chronic phlegm were not significant when compared with a group of nonexposed blue collar workers. Three cases of mild restriction of lung volume were noted. Of the 47 chest X-rays taken, one employee had a median reading of 1/1. This same individual also showed moderate obstruction upon pulmonary function testing. The authors conclude that there was a potential hazard from exposure to diesel exhaust and nitrogen- dioxide. The authors recommend specific measures to reduce these occupational exposures.

A walk through survey, and medical and environmental evaluations were conducted at the mine and mill. Diesel equipment was used in the mine. Sub micron particulate exposures ranged from 0.31 to 1.32mg/m3. The most significant source of particulates was diesel exhaust. None of the 20 personal breathing zone or area air samples collected in the mill exceeded limits for asbestos. An increased prevalence of chronic cough and phlegm was reported by workers. Chronic symptoms were reported by underground workers in all smoking categories, but only by those surface workers who also smoked. More complaints of eye irritation and tearing of the eyes were noted in underground workers, consistent with diesel byproduct exposure. Pulmonary function studies indicated that four workers had mild obstructive lung disease and one had moderate obstructive lung disease. Three workers with mild restriction of lung volume were also noted. None of the 61 chest films taken was positive for pneumoconiosis. The authors conclude that a potential hazard existed from exposure to diesel exhaust. The authors recommend that occupational exposures to workplace contaminants be reduced. A follow up medical questionnaire survey should be conducted after the implementation of exposure controls.

(Click to show more)In response to a request from employees of the New York Telephone Company (SIC-3661) Central Office facility in White Plains, New York, a study was conducted on possible exposures to electromagnetic fields (EMFs) and chemicals as well as indoor air quality in response to a concern about a perceived high incidence of cancer among employees working on the third floor of the building. Air and dust samples were collected and analyzed for trace metal content, temperature, relative humidity, and carbon-dioxide levels; the presence of EMFs and ionizing radiation was evaluated as well. In addition employees were given medical evaluations. All EMF measurements were within the American Conference of Governmental Industrial Hygienists occupational exposure standards. Adequate ventilation and very low levels of chemical exposures were seen. Humidity exceeded recommended levels in several areas. Radioactive vacuum tubes had previously been in widespread use at this facility. The authors conclude that exposures to trace levels of chemical contaminants should not be in excess of occupational standards. Electrical shock potential existed. Electric and magnetic fields did not exceed occupational standards. The role of ionizing radiation from vacuum tubes previously in use must be considered in any study of cancer among telephone company central office employees.

A private physician had reported that one of his patients seemed to have severe pneumoconiosis, probably silicosis. This patient had been a railroad maintenance of way employee for the company for about 20 years as a track laborer. Environmental sampling was conducted during track maintenance activities by Timber and Surfacing Gangs at three sites. Of the 50 personal breathing zone and 21 area samples collected for respirable dust and crystalline silica, 27 of the personal and ten of the area samples equalled or exceeded the NIOSH recommended limit for respirable quartz of 0.05mg/m3. A medical survey of 32 track maintenance workers found no evidence of pneumoconiosis or adverse respiratory health effects. The overall prevalence of chronic cough was 31% and for chronic phlegm and shortness of breath, 25% each. The authors conclude that Timber and Surfacing Gang workers were being overexposed to crystalline silica. There was a potential for excessive crystalline silica exposure for track maintenance workers. The authors recommend measures to reduce exposure and for medical surveillance.

The pilot program involved testing the three methods in unoccupied buildings contaminated with deteriorated lead (7439921) based paint. A visit was made to the site to observe work practices, and conduct air, surface, and bulk sampling for lead. The three cleaning methods included dry scraping followed by broom sweeping, wet scraping followed by high efficiency particulate air (HEPA) filtered vacuuming, and wet scraping followed by HEPA vacuuming with a HEPA filtered air filtration device placed in the room to exhaust room air to the outside. Six workers cleaned 18 rooms in 1 day. Sampling for lead was conducted before, during and after cleaning. The authors conclude that workers were potentially overexposed to lead during the three methods. The wet HEPA method was the best for controlling lead exposures. Even using this method, lead exposures during cleaning reached 50 micrograms/cubic meter. The cleaning effectiveness of the three methods was not significantly different. The authors recommend that the contractor furnish workers with NIOSH approved HEPA filter respirators, protective clothing, a clean change area, handwashing facilities, and job specific hazard training.
