“Unlocking the Secrets of the GHS: A Breakdown of Essential Components”



Safety Data Sheet (SDS): This is the major source for spreading details regarding a chemical product’s risks. An SDS must contain the minimal amount of information required by the GHS & have 16 sections in a specific order.

Labels: Labels are a vital component of hazard communication & help to distinguish between substances and their dangers. The GHS mandates that specific information, such as the chemical identity, danger statements, signal words, and symbols, appear on the label of a chemical product. In the event that your regulatory authority requires them, cautionary remarks can also be necessary.

Hazard Group: The GHS categorises hazards into three main groups: environmental, physical, and health-related. This makes it simpler to comprehend & respond to a chemical product’s threats by categorising them.

Class: The various kinds of risks that a chemical product may present are classed. For instance, one of the classes under the physical hazards category is Gases Under Pressure.

Category: The subdivisions of classes are described by categories. Self-Reactive Chemicals, for instance, have 7 classifications. The chemicals that are assigned to each group are determined by certain rules or criteria. Numbers (or letters) are given to categories, with category 1 (or A) as the most hazardous.

Hazard Statement: A common statement is used to express the risk for each category within a class. For instance, the danger statement for substances that fit the description for the class Self-heating substances & mixtures, Category 1, is Self-heating; may ignite. This warning is stated both on the label & the SDS.

Precautionary Statement: These are standardised statements that outline the actions that should be followed to reduce or eliminate the negative consequences of exposure to, or those brought on by inappropriate handling or storage of a hazardous product.

Signal Word: The GHS utilises the signal phrases “Danger” & “Warning” to convey the level of hazard. These signal words, which are predetermined by the categorization system, are utilised on both the label & the SDS. For instance, the signal word for Category 1 Self-heating substances & mixtures is Danger, whereas Category 2’s less hazardous designation is Warning. In certain categories, no signal word is employed.

Pictogram: Pictograms are images that appear on a chemical product’s label & SDS. They assist in promptly identifying the risks connected to the product. Not all categories are represented by a pictogram.


This map gives a general overview of the GHS’s essential elements & how they interact to convey information about the dangers of chemical goods. The GHS contributes to ensuring that workers, customers, & others can comprehend & react to the dangers connected with these items, regardless of where they are used or who is using them, by regulating the way that this information is communicated.
