Abstract: Spotters and samplers around the drill rigs can be exposed to high dust concentrations. In this study it was found that individuals were exposed to as much as 14.2 mg/m 3 , which exceeds the OEL (Occupational Exposure Level) of 10 mg/m 3 . The work on which this paper is based included an extensive literature study, as well as field investigations. Number of additional dust suppression interventions was identified. These improvements, listed below, will assist in reducing dust concentrations arou…
