HHE Report No. HETA-85-441-1765, New Boston Coke Corporation, New Boston, Ohio.
NIOSH 1986 Dec:8 pages
In response to a request from the Industrial Commission of Ohio, worker complaints of skin disease at the New Boston Coke Corporation (SIC-3312), New Boston, Ohio were investigated. The request was based on seven reports of dermatitis thought to be associated with steam exposure during coke (65996772) quenching. A maximum of approximately 48 workers were potentially exposed. Process materials, soaps, and skin cleansers used in the facility were evaluated qualitatively, and quench water was analyzed for pH and contaminants and was patch tested on rabbits. Medical examinations and review of records of the seven affected individuals were performed. Quench water had a pH of 8.85 and contained phenol (108952), ammonia (7664417), calcium-oxide (1305788), and suspended particulates (82 percent organic compounds); no irritant threshold levels were found for these compounds. Skin tests in rabbits showed a minimal irritant capacity for quench water. Medical records did not reveal the origin of dermatitis. Active skin lesions were characterized as nummular eczema or atopic dermatitis, which were not thought to be of occupational origin. The author concludes that coke quenching steam does not pose a skin hazard, but certain work activities may aggravate existing skin conditions. Recommendations include elimination of abrasive cleansing agents, use of skin moisturizers after washing, and prompt medical evaluation of skin complaints.
