- The Globally Harmonized System (GHS) provides a universal framework for the classification and labeling of hazardous chemicals.
- The primary goal of GHS is to ensure that the risks associated with hazardous chemicals are immediately recognizable to workers, regardless of their location.
- GHS labels contain essential information, including product identifiers, signal words, hazard statements, precautionary statements, and manufacturer details.
- The use of pictograms is a critical aspect of GHS labels, aiding in quick and universal recognition of hazards.
- Different countries may have different adaptations of GHS, but the core principles remain the same, ensuring uniformity.
Introduction to GHS
The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) was introduced by the United Nations in 1992 to address a longstanding issue plaguing industries worldwide – the inconsistent labeling and classification of hazardous chemicals. In the absence of standardized guidelines, workers handling these chemicals often lacked the necessary information to do so safely. This scenario was even more precarious when dealing with chemicals sourced from different countries.
The GHS aims to resolve this confusion by providing a universal system that classifies chemicals based on their hazards and provides clear, comprehensive, and recognizable labels. With more than 65 countries already implementing the system, the GHS has significantly improved safety in workplaces dealing with hazardous chemicals.
GHS: The Cornerstone of Chemical Safety
GHS is more than a set of guidelines – it’s a life-saving tool. It offers a framework for countries to develop a compliant hazard communication system that enhances workers’ safety. It standardizes the processes of classifying, labeling, and identifying hazardous chemicals. This system dramatically reduces risks associated with misunderstanding or lack of information when handling dangerous substances.
Before GHS, a company in Canada, for instance, receiving a shipment of chemicals from Germany could struggle to understand the contents of the containers due to differing labeling systems. With GHS, the same company can now immediately recognize the hazards associated with the received chemicals, preventing potential accidents and harm.
Components of a GHS Label
A GHS label comprises six vital elements designed to communicate key information about the hazardous chemical it labels.

1. Product Identifier
The product identifier is the specific name given to the hazardous chemical. This could be its chemical name, code number, or batch number. The same identifier must be used in both the GHS label and the accompanying Safety Data Sheet (SDS) under section 1.
2. GHS Signal Words
Signal words on a GHS label indicate the relative level of hazard presented by the chemical. There are only two such words: ‘Warning’ for less severe hazards and ‘Danger’ for more severe ones. Only one signal word is used on a label, with ‘Danger’ taking precedence if multiple hazards are present.
3. Hazard Statements
Hazard statements describe the nature of the chemical’s hazard. All relevant hazard statements must be present on the label. These statements can be combined for brevity and readability, but they must still accurately convey the dangers involved.
4. Precautionary Statements
Precautionary statements guide workers on the precautions necessary to minimize exposure and ensure safe handling and storage of the chemical. They cover prevention, response in case of accidents, proper storage, and safe disposal of the chemical.
5. Name, Address, and Telephone Number
This information pertains to the entity responsible for the chemical container, be it the manufacturer, distributor, or importer.
Pictograms are graphical symbols that provide a quick visual representation of the hazards associated with the chemical. GHS makes use of standardized pictograms to ensure universal recognition and understanding. Each pictogram corresponds to a specific hazard category, such as flame, health hazard, corrosive, or environmental hazard.
These six components work together to create a comprehensive and easily understandable GHS label. By including all the necessary information, the label enables workers to quickly assess the potential risks associated with a hazardous chemical and take appropriate precautions.
Global Adaptation of GHS
While the core principles of GHS remain the same across different countries, there may be slight variations in how each country implements and adapts the system. Some countries may add supplementary information or additional hazard categories to address specific local requirements. These adaptations aim to maintain the underlying principles of GHS while accommodating country-specific regulations and practices.
Despite these variations, the fundamental goal of GHS is to achieve global harmonization in the classification and labeling of hazardous chemicals. This harmonization ensures that workers worldwide can easily recognize and understand the hazards associated with the chemicals they handle, regardless of their geographical location.
The Globally Harmonized System (GHS) has revolutionized the way hazardous chemicals are classified and labeled. By providing a universal framework for hazard communication, GHS ensures that workers have access to essential information to handle chemicals safely. The standardized GHS labels with their product identifiers, signal words, hazard statements, precautionary statements, manufacturer details, and pictograms play a crucial role in improving workplace safety.
Thanks to GHS, the risks associated with hazardous chemicals are now immediately recognizable to workers across different countries. As more nations adopt and implement GHS, the global harmonization of chemical classification and labeling continues to enhance safety standards and protect workers worldwide.
