Exposure scenario

Explained

REACH defines an exposure scenario as the set of conditions, including operational conditions and risk management measures, that describe how a substance is manufactured or used and how exposure of humans and the environment is controlled. It comes from the chemical safety report of the registration. Where such a report is required, the relevant exposure scenarios are annexed to the safety data sheet (Art. 31(7)), which people then call an extended safety data sheet (eSDS). Downstream users check whether their use is covered. If it is not, they adapt their measures or prepare their own assessment. Formulators of mixtures carry the relevant information of the ingredients into their own sheet; ECHA guidance describes the forms this can take.
