In the context of labels, what does the term "pictogram" refer to?

The term "pictogram" in the context of labels specifically refers to a graphical representation of a hazard symbol, designed to convey specific safety information at a glance. Pictograms are a key component of labeling systems, such as the Globally Harmonized System (GHS) of Classification and Labelling of Chemicals, and are used to communicate the nature of the hazards associated with a chemical substance or preparation.

These visual symbols are critical for ensuring that users understand the risks involved without needing to rely solely on text, which may be difficult to comprehend, especially for non-native speakers. Pictograms enhance safety by providing an immediate visual cue about the potential dangers, such as flammability, toxicity, or environmental hazards.

In contrast, the other options do not align with this concept; a decorative design or brand logo does not convey hazard information, and a barcode is primarily meant for inventory management and tracking rather than for communicating safety information.
