Safety and Health The top priority at Avient is the safety and health of our associates, and our ultimate goal is to operate injury free. In preparing competitive market data for 2023, we drew from two independent sources. The second independent source of data that we used to augment the peer proxy analysis was the Consultant’s analysis of competitive market data relating to other applicable general industries.

Avient has transitioned our Material Safety Data Sheets (MSDSs) to Safety Data Sheets (SDSs) for our manufactured products to meet the requirements of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), and CLP classification in Europe.
