Under REACH, the EU´s chemicals legislation, manufacturers have to provide chemicals safety reports and exposure scenarios to their downstream users, as part of a safety data sheet to professional users. ECHA publishes examples of exposure scenarios for communication in the supply chain. An exposure scenario is a set of conditions that describe how a substance is manufactured or used, and the measures necessary to control exposure to humans and releases to the environment.

In the examples, the sections of an exposure scenario (ES) and content for different uses are illustrated to help industry generate clear and useful information for downstream users. It shows how a registrant can extract the relevant information from the comprehensive exposure scenarios in a CSR and communicate this effectively in exposure scenarios for the downstream user, using standard phrases. The example was generated using ECHA's tool for developing chemical safety assessments (CHESAR), which also generates exposure scenarios for communication.

ECHA is developing these activities under the CSR/ES roadmap to improve the generation and communication of exposure Scenarios.
