Use scenarios
A use scenario describes the conditions under which a substance or mixture is used.
A use scenario can be used for different substances (in mixtures) with an identical life cycle. A plasticizer and a pigment used in plastics would have the same life cycle. In contrast a solvent and a pigment in a paint require two different use scenarios, since the solvent evaporates during use and the pigment remains on the painted object.
You can only link a substance to one use scenario for an assessment, e.g. “Solvent in paints”. If you want to assess the substance in a further use, e.g. coolant in a closed circuit", it is best to duplicate the substance, adjust its name and select the other scenario. Alternatively, you could also change the link to the use scenario, but you cannot add a second one. The link with the first scenario will then be lost. In both cases, please make sure to also change use-specific parameters under the menu item "Exposure potential".
If you assess the exposure of a mixture, you must link all the substances contained in it to the corresponding use scenarios. Since substances behave differently in a mixture (see above pigment vs. solvent), the use scenarios of different substances in a mixture can differ.
Make the life cycle clear to yourself and choose a clear name for the scenario, e.g. 'solvents in paints and adhesives' or 'pigments used in products'.
First select which life cycle steps are relevant and then define the conditions that occur at these stages.
