Industrial Hygiene Walk-Through Survey Report of Monsanto Commercial Products, St. Peters, Missouri.
NIOSH 1978 Oct:38 pages
Worker exposure to X-ray radiation and arsenic (7440382) were surveyed at Monsanto Commercial Products Company (SIC-2833) in St. Peters, Missouri, on September 1, 1978. The survey was part of a study of developing energy technologies. The total number of employees was about 1,200, of whom 800 were in the production area. The company had safety, industrial hygiene, and medical programs, and a safety and health supervisor. An industrial hygienist was employed at the factory and the corporate headquarters by the insurance carrier. There was also a safety director and a part time doctor was on call. Pre-employment and periodic medical examinations were conducted. Automated personnel records and payroll records were available. Employees exposed to X-rays wore thermoluminescent dosimeter rings. The average annual exposure to X- rays was 17 millirems (mrem), which was below the permissible limits of 75,000mrem. Beam and scattered alpha radiation was consistent with background levels. Concentrations of respirable dust were less than 0.1 milligrams per cubic meter. Arsenic concentration was 1.7 micrograms per cubic meter. Dust samples were below 0.1 micrograms per cubic meter of total dust. The author concludes that the health and safety program was good but deficient in experience and audit functions, and they recommend that additional arsenic exposure through skin contact, workplace air amd ambient air be evaluated.
