These Signs us the GHS standards to identify hazardous chemicals. The Globally Harmonized System of Classifying and Labeling Chemicals (GHS) was created to standardize chemicals according to their hazards. The purpose of GHS is to simplify chemical hazard identification, especially during shipping and transport, regardless of spoken language. This system seeks to accomplish this through a homogenized set of GHS Pictograms, GHS Labels, GHS Signs, and GHS Safety Data Sheets.
