Globally Harmonised System of Classification and Labelling of Chemicals

The Globally Harmonised System (GHS) is a UN-developed international framework for standardizing chemical hazard classification and communication. Its core purpose is to define health, physical, and environmental hazards of chemicals and to convey this information through standardized labels and Safety Data Sheets (SDS). Unlike general risk management frameworks like ISO 31000, GHS focuses specifically on hazard identification and communication. It provides the foundational, consistent data necessary for risk assessment within broader systems, such as an ISO 45001 occupational health and safety management system. It is implemented through national regulations, like OSHA's Hazard Communication Standard in the US.

GHS application in ERM involves three key steps. First, Inventory and Classification: companies must identify all chemicals and classify their hazards according to GHS criteria, typically using supplier SDS. Second, Hazard Communication: based on classification, compliant labels with pictograms and signal words are created and affixed to containers, and updated SDS are made accessible. Third, Risk Assessment Integration: GHS hazard data is fed into the corporate risk assessment process (per ISO 31000). For instance, a chemical classified as a GHS Category 1 carcinogen triggers a high-risk rating, mandating stricter controls. A global chemical company reduced workplace chemical exposure incidents by 20% after integrating GHS into their ISO 45001 system.

Enterprises face three main challenges with GHS. 1) Regulatory Divergence: While GHS is global, national implementations (e.g., in the US, EU, Taiwan) have minor differences, creating compliance complexity for exporters. 2) Supply Chain Data Inconsistency: The accuracy of a company's GHS compliance depends on the quality of supplier SDS, which can be outdated or incorrect. 3) Lack of In-house Expertise: Small and medium-sized enterprises often lack the toxicological expertise to interpret complex chemical data correctly. Solutions include using compliance software to manage multi-jurisdictional requirements, establishing a supplier SDS verification program, and engaging external consultants for expert guidance. A prioritized rollout focusing on high-hazard chemicals is recommended.
