• Description:
  Worker exposure to silica (7631869) and crystalline alpha-quartz (14808607) particulates, hydrogen-fluoride (7664393), nitrogen- dioxide (10102440), nitric-oxide (10102439), arsenic (7440382), trichlorotrifluoroethane (76131) and isopropanol (67630) were surveyed at Monsanto Commercial Products Company (SIC-2833) in St. Peters, Missouri, from April 10 to 12, 1979. The survey was part of a study of developing energy technologies. A walk-through survey had been conducted on September 1, 1978. Over a 1000 workers were employed, half of whom were female. Pre-employment and periodic medical examinations were conducted. Industrial hygienists were available locally and at corporate headquarters. The medical program was limited to general industrial health. Analysis of personal and area samples indicated concentrations of particulates, hydrogen-fluoride, and nitric-oxide of 0.02 to 0.52, 0.01 to 3.45, and 0.09 to 0.17 milligrams per cubic meter (mg/CuM), respectively. Concentrations of arsenic ranged from 11.3 to a short-term peak of 87.3 micrograms per cubic meter. The authors conclude that personal exposures were well below applicable standards. They recommend improvement of the ventilation system and collection of periodic wipe samples in the diode production area. [Description provided by NIOSH]
