Industrial Hygiene Survey Report No. IWS-143-12, Olin Corporation, Moundsville, West Virginia.
NIOSH 1984 Mar:18 pages
An industrial hygiene survey at the Olin Corporation (SIC-2869), Moundsville, West Virginia was conducted in August 1983 to determine if a health hazard existed from 4,4'-methylenedianiline (101779) (MDA). The facility employed 300 workers, most of whom were middle aged. Environmental and breathing zone samples were analyzed for MDA. Dermal samples were also analyzed for MDA. Ventilation measurements were made. All air, environmental, and dermal samples showed MDA exposures to be less than the American Conference of Governmental Industrial Hygienists (ACGIH) recommended standard of were probably low due to problems with sample loss in the analytical method for MDA. The analytical results for the other samples were considered to be reliable. Air velocity measurements showed ventilation rates in several locations, especially the drumming operation, to be less than the 100 feet per minute recommended by ACGIH. The author concludes that dermal contact with MDA probably affected only six employees. Recommendations include improved exhaust ventilation and the use of personal protective equipment.
