The EMKG-Expo-Tool 2.0 is a first tier IT-tool to estimate the inhalation exposure at the workplace to fulfil the obligations arising from REACH. The tool uses a control banding approach, based on the "Easy-to-use workplace control scheme for hazardous substances (EMKG)". Requiring only three input parameters, the tool's simple structure enables the user to distinguish quickly between critical and non-critical workplace situations. The tool offers a simplified approach to evaluate worker exposure and identify RMMs requiring a small number of input parameters. Thus the tool is easy to use and still allows quantitative exposure estimations.
