What shape is a pictogram on a chemical label?

The pictogram on a chemical label is represented as a square or diamond shape. This shape is specifically designed to convey information about the hazards associated with the chemical. The use of standardized shapes makes it easier for workers to quickly identify the type of hazard they may encounter.

The square shape used for pictograms is part of OSHA’s Globally Harmonized System (GHS) for classifying and communicating chemical hazards, ensuring consistency around the world. Each pictogram contains a symbol that reflects a particular hazard category, such as flammability, toxicity, or health risks, allowing for efficient communication in the workplace about the substances being handled.
