• Description:
  A study was conducted examining levels of exposure of refractory ceramic fiber workers to ceramic fibers. Dust zones were identified during a walk through survey, based on similar work tasks, materials, types of process and control technology, and identifiable group of workers. Time weighted average (TWA) exposures of randomly selected workers were calculated in different dust zones (fiber production, vacuum processes, and other) and during different workshifts at five facilities. Sampling was conducted by facility personnel for at least 360 minutes on each occasion. TWA exposures ranged from the limit of detection to 2.0 fibers/centimeter. Dust levels were not significantly variable across shifts using the entire data set. When analyzed by facility, geometric mean TWAs were significantly different between the first and third shifts at one facility. This finding could not be explained on the basis of job activities. The authors conclude that these findings support the use of a single exposure estimate for each dust zone group in each facility studied regardless of the shift worked.
