The guide “Guidance on Key Considerations for the Identification and Selection of Safer Chemical Alternatives” published by OCDE in 2021 provides a general approach and criteria for the selection of alternatives, focusing on minimum assessment criteria and recommended assessment practices for four core areas of alternatives evaluations:
- determining the assessment’s scope
- comparative hazard assessment
- comparative exposure assessment
- integration of hazard and exposure results to select a safer alternative.
The guidance also includes recommendations for moving beyond the minimum criteria and assessment practices.
