South Korea Proposes Full Revision of the “Detailed Handling Standards for Hazardous Chemicals”

On July 6, 2025, South Korea proposed a full revision of the “Detailed Handling Standards for Hazardous Chemicals” to align with recent amendments to the Chemical Substances Control Act and the Act on the Registration and Evaluation of Chemicals (K-REACH). These legislative changes shift the management system for toxic substance from a uniform to a differentiated framework based on chemical hazard levels. Consequently, the handling standards for hazardous substances need to be updated to reflect this new approach. 

Key Highlights of the Proposed Changes 

A. Updated Objective (Article 1 Draft) 

This regulation aims to establish specific handling guidelines and best practices for hazardous chemicals, as defined under Article 13 of the Chemical Substances Control Act and Rule 8, Annex 1 of its enforcement ordinance. 

B. New Definitions Introduced (Article 2 Draft) 

New terms are defined to clarify the scope of the regulation: 

• General Standards: Basic safety protocols that all handlers must follow, regardless of the substance’s hazard classification. 

• Substance-Specific Standards: Detailed handling requirements tailored to each hazardous chemical. 

• Core Handling Requirements: Mandatory safety measures based on a substance’s known risks. 

• Recommended Practices: Informational guidelines to support the safe handling of substances on-site. 

C. General Safety Requirements Established (Article 3 Draft) 

All handlers of hazardous substances must adhere to the following protocols: 

1. Fully understand the safety information before use. 

2. Wear the appropriate personal protective equipment (PPE). 

3. Avoid eating, drinking, or smoking near hazardous materials. 

4. Prevent environmental discharge through proper containment and disposal. 

5. Inform nearby personnel of potential dangers in case of spills or accidents. 

6. Dispose of any spilled or leaked chemicals in accordance with legal standards. 

Additionally, employers are responsible for ensuring immediate medical evaluation for workers suspected of exposure to hazardous substances. 

D. New Recommendations by Substance (Annex 1) 

A new annex provides guidance tailored to individual chemicals, supporting safer site-level management. 

E. Updated Hazardous Chemicals List 

The list of regulated substances has been revised and now includes new annotations for clarity and ease of use. 

F. Operational Improvements 

Minor amendments have been made to enhance the regulation’s usability and enforceability. 

Public Comments Invited 

Organizations, associations, or individuals who wish to provide feedback on the draft revision must submit their comments to the Chemical Safety Agency by July 27, 2025. Submissions should include relevant contact details and clear feedback on the proposed changes.
