Praktijkvoorbeelden van blootstellingsscenario's
ECHA has developed an illustrative example of exposure scenarios (ES) to help suppliers generate exposure scenarios for their customers. 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 illustrative example ES was generated using ECHA's tool for developing chemical safety assessments (CHESAR), which also generates exposure scenarios for communication. The example includes the following elements:
- Part 1: An Introductory Note
gives an overview of the format for the ESs to be annexed to the safety data sheet (SDS), advice regarding the selection of standard phrases and how this was done in the illustrative example. It also includes general points to consider when preparing such exposure scenarios.
- Part 2: An example of Exposure Scenarios
is an illustrative example of exposure scenarios to be annexed to the safety data sheet. It exemplifies how the information contained in the exposure scenarios developed for a chemical safety report can be extracted effectively and communicated in the ES annexed to SDS. This example is derived from the "Illustrative Example of Chemical Safety Report" published on ECHA website for a hypothetical substance (the so-called "ECHA substance").
- Part 3: Chesar 2.3 substance file
This file is the Chesar 2.3 file from which the exposure scenarios in the example have been generated. Chesar is ECHA's tool for developing chemical safety assessments, and was used to prepare the illustrative example CSR and the exposure scenarios for communication.
Other practical examples
This is an illustrative example of an exposure scenario for the chemical safety report. It shows how the article service life can be assessed and how meaningful exposure scenarios can be generated from the assessment for a hypothetical substance. Factors to consider within such an assessment are explained. The exposure scenario for the chemical safety report has been generated with ECHA's Chemical Safety Assessment and Reporting tool, Chesar (version 2.3).
The files below show examples of ES in different sectors. These examples do not follow current practice in terms of format or use of standard phrases. They are currently under review and may be updated.
