The main objective of this monitoring protocol is to provide a harmonized methodology to measure exposure to respirable crystalline silica (RCS) of workers employed at member companies of the NEPSI signatories.

This common basic methodology aims to help those sectors who do not have a standardized monitoring methodology in place and enable these sectors to collect RCS exposure data in a harmonized and representative way. Guidance is provided on measurement strategy, appropriate sampling and analytical methods, and data management.
