Industrial hygiene walk-through survey report on organophosphorus exposures at Chevron Chemical, Belle Chase, LA.
NIOSH 1979 Jul; :1-6
Worker exposures to tricresyl-phosphate (1330785) (TCP) were determined at Chevron Chemical (SIC-2819) in Belle Chase, Louisiana, on March 29, 1979. The company was under consideration for inclusion in a NIOSH study of the health effects of occupational organophosphorus exposure. Approximately 30 of the employees at the facility were assigned to the production areas with the greatest potential for TCP exposure. The company had a formal safety and industrial hygiene program. Medical services were furnished by a resident physician and by workers trained in first aid. Personnel records provided demographic information, department assignments, and accident reports. Air samples collected near the loading and unloading station for tank rail cars, at the circular manifold, and at the barrel filling operation contained less than 0.8 milligrams per cubic meter of TCP. The author concludes that since all TCP exposures at this facility are minimal, it should not be included in the NIOSH survey.
