What is BS EN 689 about?

BS EN 689 is an international standard that covers the measurement of exposure by inhalation to chemical agents. BS EN 689 discusses workplace exposure in compliance with occupational exposure limit values. It specifies a strategy to perform representative measurements of exposure by inhalation to chemical agents in order to demonstrate compliance with occupational exposure limit values (OELVs). To assess the exposure of workers to chemicals and to state with certainty that it does not exceed the occupational exposure limit values (OELVs) (short-term or long-term) would require measurement of the exposure of every worker for every working day. Unfortunately, while this approach is possible for some agents such as ionizing radiation, it is not feasible or practical for many chemical agents due to limitations of the measurement techniques and costs.
