Environmental Health & Safety GHS Pictograms

Pictograms

The GHS aligned Hazard Communication Standard (HCS) establishes new symbols called pictograms which are required on labels and safety data sheets. Pictogram means a composition that may include a symbol plus other graphic elements, such as a border, background patter, or color, that is intended to convey specific information about the hazards of a chemical. Eight pictograms are designated under the HCS for application to a hazard category.

You may be familiar with some of the pictograms while others may be completely new to you. It is important that every WSU employee that uses hazardous chemicals be familiar with the pictograms and associated hazards listed below. Some of the pictograms are straightforward and represent only one hazard, such as the flame over circle pictogram for oxidizing chemicals. Other pictograms can represent multiple hazards, such as the health hazard pictogram for carcinogen, mutagen, reproductive toxicity, etc.

The Hazard Communication Standard establishes new symbols called pictograms, which are required on chemical labels and Safety Data Sheets (SDS). While you may be familiar with some of the pictograms, others are brand new or may be unfamiliar to some people. Some of the pictograms represent one type of chemical hazard (e.g. acute toxicity) while others represent multiple hazards (e.g. carcinogen, mutagen, reproductive toxicity, etc.).
