The aim of this study is to determine exposure levels as well as compliance status on respirable dust and respirable crystalline silica (RCS)-quartz exposure among crusher operators at Malaysian quarries. The exposure level at each crushing process was compared. Monitoring was performed among 70 crusher operators at nine quarries. Eight hours long-term personal samples were collected according to the National Institute of Occupational Safety and Health (NIOSH) Manual Analytical Method (NMAM) 0600 for respirable dust and NMAM 7500 for respirable crystalline silica (RCS-quartz).
