This document discusses control banding, an approach for managing chemical exposure risks. It provides: 1) An overview of the origins and development of control banding, including the COSHH Essentials model and tools like Stoffenmanager and Advanced REACH Tool. 2) Evidence that validation studies have found control banding tools can reliably predict exposures when used correctly, but training is needed for effective implementation. 3) Suggestions that control banding tools could be improved by more strongly encouraging continuous improvement through a "Kaizen" approach, providing better guidance to "nudge" protective actions, and integrating exposure measurement data.
