Studying respirable silica exposures among brick workers in Nepal, we found that ≈11% of samples (25/232) had pump flow rates that drifted beyond ± 5% when post-calibrated. Flow rate directly influences particle sizing when using pre-separators. Sample duration, measured respirable dust concentration, person calibrated, calibrator, and participant job category were examined as possible factors. Samples were collected following NIOSH Method 0600. Understanding this may save time and costs when conducting personal sampling.
