Hazard Communication Standard: Pictograms

As of June 1, 2015, the Hazard Communication Standard (HCS) will require pictograms on labels to alert users of the chemical hazards to which they may be exposed. Each pictogram consists of a symbol on a white background framed within a red border and represents a distinct hazard(s). The pictogram on the label is determined by the chemical hazard classification.

What are pictograms?

Generally speaking, a pictogram is a symbol or picture which represents a word or idea. We see pictograms everyday in signs and labels. We are all familiar with the “No Smoking” pictogram posted in public buildings. and the “No diving” signs painted on the decks of swimming pools. The Department of Transportation (DOT) routinely requires labels with pictograms for vehicles carrying hazardous materials.
