The Globally Harmonized System for Hazard Communication (GHS) is a set of standards for the labeling of chemical products and identifying the hazards associated with them. GHS was adopted by the United Nations as a universal system to promote the safe transportation, use and storage of hazardous materials. In 2009, the Occupational Health and Safety Administration proposed aligning the Hazard Communication Standard with GHS standards.
One of the key changes that came with the adoption of GHS was the introduction of the hazard pictograms. These pictograms are used to symbolize the hazards associated with a particular product so that workers all over the world, no matter what language they speak, can understand the dangers of the materials they are handling. There are nine GHS pictograms; each one and their meanings are listed below.
