Workers frequently complained of allergic and flu or cold like symptoms such as runny nose, congestion of the nose, throat and lungs, fever, and eye irritation by the end of the show. Measured levels of respirable and total dust, silica (14808607), and carbon-monoxide (630080) were below the recommended criteria levels. Biological activity such as ergosterol, spore count, and endotoxin levels were higher on the first floor of the Hall of Education and in the Stadium Hall, both areas where high numbers of animals were housed. Spore counts and ergosterol levels were consistent with the levels found in other studies where adverse health effects had occurred. Throughout the Hall of Education, the carbon-dioxide (124389) levels were well above the 1,000 parts per million (ppm) level. These levels averaged 2,000ppm and ranged up to 4,300ppm. The need for outside air ventilation throughout the complex was noted. Consistently high readings for carbon-dioxide were also observed in the promenade area around the Coliseum. The authors suggest that the ventilation system in the Event Center be adjusted to introduce outside air for dilution prior to a certain preset time.

Workers were concerned about exposures to alumino-silicate fiber insulation which lined the interior of the industrial furnaces. A total of 16 time weighted average personal breathing zone and work area samples were collected and analyzed for total and respirable particulates. Respirable quartz (14808607) was detected in one refractory ceramic fiber (RCF) removal sample, below the minimum quantifiable concentration. No cristobalite was detected in any of the samples. The ten time weighted average area total particulate samples from Heat Treatment Plant Number One and RCF removal operations ranged from 0.10 to 0.52mg/m3. No quartz or cristobalite was detected in any of these samples. It was recommended that workers handling RCF should wear specific levels of respiratory protection and that company officials should monitor RCF concentrations regularly to characterize the task specific exposures to RCF. Such information will assist the company in determining the appropriate level of respiratory protection for specific tasks.

Employees were concerned about exposure to contaminants during collection and blending of coal-tar sludge with coal. The facility employed 400 workers and produced about 1,000,000 tons of coke annually at full capacity. A questionnaire was administered and measurements were taken of 1-hydroxypyrene (5315797) (1-HP), as an indicator of polycyclic aromatic hydrocarbon exposure. Samples were taken from 18 of 22 workers in the coal handling area. Testing revealed exposures to coal-tar-pitch volatiles, polynuclear aromatic hydrocarbons, and potentially benzene (71432), which exceeded the recommended exposure levels during the processing of coal-tar sludge. Improper use of personal protective equipment was also noted. Urine 1-HP levels indicated excessive exposures to pyrene (129000). The authors conclude that a health hazard existed due to exposure to contaminants. There was a potential for skin contact with coal-tar sludge. The authors recommend specific measures to reduce the hazardous exposures to the workers at this site.

The owner (and employee) voiced concern about optical radiation, crystalline silica (14808607), metals, volatile organic compounds, and decomposition products which were generated during the production of handmade decorative glass items. Personal breathing zone and area air samples were collected during the major steps in producing glass artwork. Levels of radiant energy were also measured. All of the exposures measured were significantly below any pertinent occupational limits. There was no detectable crystalline silica in either the air or bulk samples collected. Ultraviolet and visible radiation exposures were not in excess of the applicable standards, but it was possible to be exposed to excessive infrared levels when working with the kiln or glory hole equipment. The author concludes that a health hazard did not exist at the time of the survey. The authors recommend that eye protection be used because of exposure to particulate matter and optical radiation.

The company employed about 20 workers in the surface preparation and painting of steel plate water tanks at sites throughout the country. Environmental sampling was perform at two sites in Pennsylvania. Workers were noted to be overexposed to crystalline silica (14808607) during tank interior sandblasting and shoveling operations at the Pike County site. Airborne concentrations of respirable silica during blasting exceeded the recommended exposure limit (REL) from NIOSH by a factor of 300 to 540. An abrasive blasting hood with an assigned protection factor (APF) of only 25 was used. During sand shoveling operations the REL was exceeded by a factor of 94 while the respirator with an APF of only 10 was used. Deficiencies were noted in the respiratory protection and hearing conservation programs at the site. Eleven of the 13 employees at these sites participated in the medical evaluation. Three had abnormal spirometry test results, and an obstructive pattern of abnormalities. The authors conclude that a health hazard existed at the time of the survey due to exposure to respirable crystalline silica. The authors recommend that effective respiratory protection, hearing conservation, and medical surveillance programs be implemented, and a less toxic abrasive blasting material be used.

Complaints received included gastrointestinal disturbances, sore throats, fatigue, headaches, eye irritation, and coughing among those working in the belt press room. Personal breathing zone samples for total particulate ranged from 0.03 to 0.28mg/m3. Measurements also indicated a range of 2.50 to 6.82 endotoxin units per cubic meter of air. Sludge samples containing 40% solids had the highest concentrations and largest variety of volatile organic compounds. Analysis indicated that the belt room workers were exposed to hydrogen-sulfide (7783064) at concentrations which exceeded the NIOSH 10 minute ceiling of 10 parts per million (ppm) in eight of 13 breathing zone samples; three also exceeded the OSHA limit of 20ppm. The author concludes that workers were overexposed to hydrogen-sulfide. The author recommends that continuous monitoring be provided for employees in or around the belt press room to evaluate hydrogen-sulfide exposure levels. Engineering controls should be used to reduce hydrogen-sulfide levels. Until the improvements are made, workers should use respiratory protection.

Concern had also be expressed regarding potential exposures to crystalline silica (14808607) and asbestos (1332214). MBL-USA manufactured a wide variety of belts for both original equipment and service parts in the industrial and automotive markets. Approximately 210 workers were employed on site at the time of this study. Personal breathing zone and general area air samples were collected. Levels of nitrosodiethylamine (55185) (NDEA) in the Ring and Press Curing areas ranged up to 0.55 micrograms per cubic meter. A personal breathing zone air sample collected on the powder applicator contained 0.13mg/m3 respirable particulates, well below the OSHA permissible exposure limit of 5mg/m3. The bulk powder used to coat the belts was not found to contain asbestos or crystalline silica. The author concludes that no health hazards were documented. The author recommends that improvements be made in the effectiveness of the canopy hood ventilation systems in the Cure Press area, and that the personal protective equipment used in the Banbury area be improved.

Six area air samples and five bulk fly ash samples were collected. Greater amounts of PCDDs/PCDFs were present on the fly ash particulates collected from the electrostatic precipitator (ESP). A total of eight personal breathing zone and nine area samples were collected for metals during cleanout operations. Levels approached or exceeded the established criteria for arsenic (7440382), cadmium (7440439), lead (7439921), and nickel (7440020). For respirable dust/silica (14808607), the highest sample concentration occurred during ESP cleanout. The NIOSH recommended exposure limit for respirable quartz of 0.05mg/m3 was exceeded in one sample. The authors conclude that a health hazard existed during cleanout operations. The authors recommend that measures be taken to reduce exposures, including providing more effective respiratory protection, instruction on confined space entry, medical surveillance programs, and the prohibition of tobacco smoking in exposure locations.

Concern was expressed regarding the exposure of press operators and millmen to N-nitroso compounds and dusts which were generated while rubber flooring was being manufactured. Of the approximately 200 workers employed by RCA, about 60 were in jobs with the potential for exposure to nitrosamines and dusts. The production workers were tested for personal breathing zone contamination, and area workplace samples were also collected for nitrosamines, respirable dusts, elemental metals, formaldehyde (50000), carbon-monoxide (630080) and sulfur- dioxide (7446095). Only N-nitrosopiperidine (100754) was detected in the samples collected, and the concentrations were low in the samples where it appeared. Respirable dust levels ranged from 0.03 to 3.17mg/m3. In an analysis of 12 work area samples, only trace quantities of metals were detected. The authors conclude that, due to the findings of this study, the mandatory use of respiratory protection by mixing and press personnel should be reviewed by company officials. The continued use of dust respirators was recommended for three areas of the facility until engineering controls could be implemented.
