The Globally Harmonized System of Classification and Labelling of Chemicals (GHS), provides harmonised hazard communication elements, such as labels and safety data sheets, and addresses the classification of chemicals by hazard type. The building blocks of the GHS are the hazard classes or categories according to the type of hazard, i.e. physical, health and environmental etc.
GHS labels shall include the following elements:
1. Signal Words
These signal words indicate the severity level of the hazard. On the other hand, as of now, there are 2 signal words i.e. “Danger” for more severe while “Warning” for less severe hazards.
2. Pictograms
Standard symbols that may carry information concerning specific chemical hazards. Currently there are 9 pictograms used to represent physical, health, and environmental hazards in the GHS.
3. Supplier Identification
This includes the name, address, and telephone number of the manufacturer or supplier of the chemical.
4. Precautionary Statements
Phrases that describe recommended measures to minimize or prevent adverse effects resulting from exposure to a hazardous product, or improper storage or handling.
5. Hazard Statements
Standardized statements assigned to a hazard class and category that describe the nature of the hazards of a chemical. Examples include “Highly flammable liquid and vapour”, “Causes skin irritation”, etc.
An example of a GHS label is shown below:
6. Product Identifier
The name or number identifying a hazardous product on the label or in the SDS. It is useful to refer to the actual chemical or mixture quickly.
7. Supplemental Information
Any information that may be an added supplement and is not required by GHS from the supplier but provides any instructions for use or any other relevant information.
These guidelines will thus ensure the safe handling, transportation, and utilization of hazardous chemicals, therefore protecting workers and the environment.
To assist companies in adhering to these GHS guidelines, a chemical regulatory compliance portal can streamline compliance by providing easy access to updated regulations, safety data sheet templates, and other GHS requirements. Such portals serve as centralized resources that help manufacturers ensure their labels, hazard classifications, and precautionary measures align with GHS standards, thus promoting the safe management of chemicals across various regions.
