• Description:
  A survey of techniques used to control occupational exposures to various trace metals, frothing agents, and organic solvents at coal preparation sites and laboratories was conducted at the EAL Corporation (SIC-1211) in Richmond, California, Carbon County, Utah, Jefferson County, Alabama, and Washington County, Pennsylvania in 1981. The laboratories were located at Clarksburg and Wheeling, West Virginia. The coal preparation facilities relied principally on natural ventilation and work practices to control employee exposure. The laboratories used ventilation and local exhaust systems as well as work practices to reduce the concentration of contaminants. Analysis of environmental and breathing zone samples at the coal preparation facilities showed that the concentration of trace metals and frothing agents were controlled to below acceptable limits. Analyses at the laboratories showed similar results except for ethylene-dibromide (106934) (EDB). Although the measured concentrations of EDB were consistently below the OSHA limit of 20 parts per million (ppm), they were above the NIOSH standard of substituted for EDB.
