Hazard pictograms alert us to the presence of a hazardous chemical.  The pictograms help us to know that the chemicals we are using might cause harm to people or the environment.  The CLP hazard pictograms are very similar to those used in the old labelling system and appear in the shape of a diamond with a distinctive red border and white background.  One or more pictograms might appear on the labelling of a single chemical.
