The 9 Hazard Communication Standard pictograms

In 2012, OSHA revised its hazard communication standard (29 CFR 1910.1200) to align with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) standards for classifying and communicating chemical hazard information.

The changes include new required pictograms for chemical labels. Each pictogram consists of a symbol on a white background framed within a red border and represents a distinct hazard(s).

Here's a look at the nine pictograms.
