This facility consists of three divisions: 1) paperboard, 2) carbon and 3) research. The area of interest during this evaluation was the carbon division. Two types of carbon are made at this facility: one from ground wood pulp and the second from bituminous coal. The evaluation consisted of an environmental evaluation, medical interviews and limited chest examination. It has been determined that although airborne concentrations of airborne carbon impregnated with phosphoric-acid were excessive during the primary evaluation of 1975, they were not excessive during the second evaluation of 1976. These determinations are based on the environmental measurements made. No conclusive determinations could be made from the medical tests performed. The process of activation with phosphoric-acid was in existence at this facility for one year prior to this study.

This determination is based upon air concentration levels of total dust containing free silica up to four times the Federal Standard for blast furnace workers and up to twenty eight times the Federal Standard for larry car operators in the stockhouse as well as criteria concerning the toxic effects of free silica. It has also been determined that potentially toxic exposures did not exist on the day of evaluation to the crane operator in the stripper building from exposure to iron-oxide (1317619) fume, carbon-monoxide (630080), and free silica or to maintenance workers in the 44 inch soaking pit area from exposure to sulfur-dioxide (7446095) and carbon-monoxide. Detectable levels of carbon-monoxide, sulfur- dioxide, and iron-oxide fume were not measured while the free silica level was less than 0.4 of the Federal Standard.

The evaluation was requested by an employee representative to evaluate exposures to flaked and molten petroleum-pitch (61789604). Environmental air sampling was performed and petroleum-pitch was analyzed using gas chromatography. Medical examinations of exposed employees were also performed. It was found that workers were intermittently exposed to vapors from molten petroleum-pitch and particles of the solidified product. Chromatographic analysis of samples from the working area showed phenanthrene (85018), pyrene (129000), benzo(a)pyrene (50328), benzo(e)pyrene (192972), 1,12- benzoperylene (191242), and anthanthrene (191264). Airborne concentrations of benzene soluble material were near or below the OSHA standard of 0.2 milligrams per cubic meter. Average length of employment of the 11 workers interviewed and examined was 12.6 years. Two workers had little exposure to petroleum-pitch. Seven of the nine workers with significant exposures reported past episodes of phototoxicity including skin discomfort, redness, and peeling resembling exaggerated sunburn responses on exposed skin surfaces. Six workers also complained of eye and upper respiratory tract irritation. Incidental findings included fungus infection, actinic keratosis, and hyperkeratotic lesions on the hand. Members of the study team also experienced skin discomfort following exposure at the work site. The authors conclude that the petroleum-pitch contained known photosensitizers which produced phototoxic reactions. Recommendations are made which would decrease dust generation and worker exposure to pitch particles. Use of a sun screen product is also suggested. Repeated and prolonged phototoxic injury to the skin may increase the danger of developing more serious skin diseases.

(Click to show more)Environmental survey of the employees of a greeting card manufacturing company through medical interviews and examinations conducted in the flocking department shows that four out of six women display symptoms related either to the skin or the respiratory tract. No evidence is found of necrosis conditions among employees working with glues containing a type of Stoddard solvent, although airborne flock does result in minor mechanical irritation from the deposition of fibers on the body, particularly skin creases. A few individuals with chronic or pre-existing throat and sinus conditions are made worse by the constant deposition of flock high in oral and nasal passages. Recommendations include improvement of dust collection and housekeeping practices, discontinuance of the practice of using compressed air to blow off dust from employees' uniforms, screening out of future potential employees with sinus and throat illness, wearing of long sleeve uniforms in the flocking area, and the use of paper face masks.
