DEFINITION
An exposure assessment is a regulatory procedure under REACH that systematically determines the nature, duration, and level of exposure of workers, consumers, and the environment to a chemical substance for all identified uses. It forms the basis for deriving appropriate risk management measures and is an integral component of the chemical safety assessment.
DeclarationExposure Assessment
The exposure assessment is a central component of the chemical safety assessment under REACH and systematically determines how workers, consumers and the environment are exposed to a chemical substance. It comprises the analysis of emission sources, exposure pathways and exposure levels for all identified uses of a substance.
During execution, both technical and organisational protective measures as well as the effectiveness of personal protective equipment are evaluated. The results of the exposure assessment flow directly into exposure scenarios, which companies must provide within the supply chain as annexes to the Safety Data Sheet (SDS).
In practice, this means: Utilise validated exposure models and robust measurement data, document all assumptions transparently, and regularly verify that actual conditions of use remain covered by your assessment. Ensure consistency between the Chemical Safety Report (CSR), the Safety Data Sheet, and internal occupational health and safety documentation to meet compliance requirements and effectively manage risks.
Key Points
- Central component of the chemical safety assessment under REACH
- Exposure scenarios describe safe conditions of use for workers, consumers, and the environment
- Mandatory component for supply chain communication via safety data sheets
- Takes into account technical control measures, organisational measures, and personal protective equipment
- Requires regular review and updating in the event of changes to the conditions of use
