CHEmical Safety Assessment and Reporting tool

What is Chesar?

Chesar is an application developed by the European Chemicals Agency (ECHA) to help companies carry out their chemical safety assessments (CSAs) and prepare their chemical safety reports (CSRs) and exposure scenarios (ES) for communication in the supply chain.

Chesar enables registrants to carry out their safety assessments in a structured, harmonised and efficient way. This includes the importing of substance-related data directly from IUCLID, describing the uses of the substance, identifying risk management measures if needed, carrying out exposure estimates and demonstrating control of risks. Based on this, Chesar automatically generates the CSR and exposure scenarios for communication in an electronic exchange format and as a text document. It also facilitates the re-use (or update) of assessment elements generated in a single Chesar instance or imported from external sources.
