Knowra Globally Harmonized System of Classification and Labelling of Chemicals Globally Harmonized System of Classification and Labelling of Chemicals The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is a United Nations framework for classifying chemical hazards and communicating them through standardized labels and safety data sheets.
Hazard : A property or situation with the potential to cause harm. GHS classifications identify the kinds and degrees of harm a chemical can cause.
Globally Harmonized System hazard classes : The GHS groupings of chemical hazards, including physical, health, and environmental hazards. Each class defines a distinct kind of danger that classification criteria assess.
United Nations Economic and Social Council : A principal United Nations body coordinating economic, social, and related international work. The Council endorsed the GHS and oversees its maintenance through expert committees.
OSHA Hazard Communication Standard : A United States workplace regulation requiring employers and suppliers to communicate chemical hazards. OSHA aligned major parts of its standard with GHS classification and labeling provisions.
United Nations Recommendations on the Transport of Dangerous Goods Model Regulations : United Nations model rules for transporting dangerous goods by road, rail, sea, and air. Transport regulations focus on shipment risks, while GHS covers broader chemical hazard communication.
Acute toxicity : Harmful effects caused by a substance after a single or short-term exposure. GHS assigns acute-toxicity categories using measured or estimated dose thresholds.
Globally Harmonized System hazard categories : GHS divisions within a hazard class that indicate degrees or forms of hazard. Category assignment determines the applicable signal word and hazard statements.
International Labour Organization : A United Nations agency that advances labor rights and international standards for work. The ILO contributed workplace expertise to the GHS and its implementation guidance.
CLP Regulation : European Union legislation on the classification, labelling, and packaging of substances and mixtures. The CLP Regulation implements GHS-based rules across the European Union.
European Agreement concerning the International Carriage of Dangerous Goods by Road : An international treaty governing the road transport of dangerous goods in Europe and its participating states. ADR regulates transport, a distinct setting from GHS workplace and consumer communication.
