Abstract

Selecting the best sampling method for respirable crystalline silica (RCS) exposure always is a debate among industrial hygiene. The dispute is always focusing on the diversity between direct and indirect method which may contribute to uncertainty in final result. The objective of this research is to define applicability of direct and indirect method in determination of RSC exposure in Malaysia. Beside, this research aims to establish performance characteristic for both methods. Parallel 8 H exposure sampling was performed among 34 workers at six granite quarries located in Kuala Lumpur and Selangor. The research focused on performance characteristic and differences between both data. Results indicate that there are no much differences between both methods in term of quality control and quality assurance performance. Besides that, inferential statistic on correlation and difference test showed there is no significant different on personal exposure data between both methods. Both methods are reliable and accurate to be used for RCS exposure measurement in granite quarry environment
