## What is an Extended Safety Data Sheet (eSDS)?

An **Extended Safety Data Sheet (eSDS)** is a Safety Data Sheet that goes beyond the standard format by including one or more **Exposure Scenarios (ES)**. Each Exposure Scenario details how a substance can be safely used — defining the **Operational Conditions (OC)** and **Risk Management Measures (RMM)** that ensure risks remain controlled.

Under EU REACH and similar frameworks, eSDS EU REACH service ensures that extended Safety Data Sheets (eSDSs) are developed and provided for substances requiring a Chemical Safety Assessment (CSA). These eSDSs serve as a key communication tool between manufacturers, importers, and downstream users, enabling safe handling, use, and disposal of chemicals throughout the supply chain

## Why is an eSDS Important?

In today’s regulatory landscape, ensuring compliance and safety transparency is not optional — it’s essential.

An eSDS helps organizations to:

- **Comply with** [**REACH regulations**](https://www.freyrsolutions.com/chemicals/global-reach-regulatory-compliance) that mandate inclusion of exposure scenarios for hazardous substances.
- **Communicate safe use information** effectively to downstream users, enabling them to verify that their operational conditions are covered
- **Manage risk proactively**, implementing appropriate OCs and RMMs to keep exposure below DNEL/PNEC thresholds.
- **Be audit-ready**, with harmonized documentation linking SDSs, REACH exposure scenario, Chemical Safety Reports (CSR), and IUCLID data.
