Development of a globally harmonized system for hazard communication

Area of Science:

• Environmental Science
• Occupational Health
• Chemical Safety

Background:

• An international mandate from the 1992 United Nations Conference on the Environment and Development (UNCED) initiated the development of a unified hazard communication system.
• The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) emerged from extensive international collaboration.
• Existing chemical hazard communication methods varied significantly across nations, necessitating a standardized global approach.

Purpose of the Study:

• To describe the development process of the Globally Harmonized System (GHS).
• To outline the core components and objectives of the GHS.
• To discuss strategies for promoting the global implementation of the GHS.

Main Methods:

• International collaboration and consensus-building among numerous countries and organizations.
• Development of standardized criteria for classifying chemical hazards.
• Creation of uniform elements for hazard communication, including labels and safety data sheets.

Main Results:

• A common and coherent system for defining, classifying, and communicating chemical hazards has been established.
• The GHS provides a framework for consistent hazard information for diverse audiences.
• The system is designed to support national programs for the sound management of chemicals.

Conclusions:

• The GHS represents a significant advancement in global chemical safety and hazard communication.
• Its adoption by the United Nations and subsequent availability for national implementation are anticipated.
• The GHS is poised to enhance chemical management and safety worldwide.
