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.
Target Organ Toxicity
Emits Flammable Gas
Irritant (skin and eye)
Respiratory Tract Irritant
Hazardous to Ozone Layer (Non-Mandatory)
Gases Under Pressure
Corrosive to Metals
Flame Over Circle
Skull and Crossbones
Acute Toxicity (fatal or toxic)
