Pictogram (GHS)
A symbol in a red diamond on a chemical label that shows the type of hazard. OSHA designates eight.
Definition, in the source's words
29 CFR 1910.1200(c)(opens ecfr.gov in a new tab)“Pictogram means a composition that may include a symbol plus other graphic elements, such as a border, background pattern, or color, that is intended to convey specific information about the hazards of a chemical. Eight pictograms are designated under this standard for application to a hazard category.”
What it means
The eight are: health hazard, flame, exclamation mark, gas cylinder, corrosion, exploding bomb, flame over circle, and skull and crossbones. Each is a black symbol on a white background in a red diamond-shaped frame. The GHS environment pictogram isn't required under OSHA's standard.
Example
A drum of acetone carries the flame pictogram (flammable liquid) and the exclamation mark (eye irritation). Flame over circle would mean an oxidizer instead, a common exam distinction.
