Position Paper: A Model for Monitoring Exposures from Chemical Agents in NZ Workplaces (Adopting EN 689:2018)
The Council of the New Zealand Occupational Hygiene Society has agreed to adopt European Standard EN 689:2018 “Workplace exposure - Measurement of exposure by inhalation to chemical agents - Strategy for testing compliance with occupational exposure limit values” as a good practice model for monitoring chemical agents in the workplace.
EN 689:2018 deals with the measurement of exposure to chemical agents in workplace atmospheres. It covers measurement strategies for comparison of workers exposure with workplace exposure standards (WES).
The strategy in this document gives procedures for occupational hygienists to overcome problems of variability using a relatively small number of measurements with a high degree of confidence so that workers are unlikely to be exposed to levels exceeding the WES. It also covers the need for occupational hygienists to conduct a basic characterisation in order to assemble all relevant information on workplace factors and on the exposure.
