What symbol represents a health hazard in the GHS system?

The symbol that represents a health hazard in the Globally Harmonized System (GHS) is characterized by a silhouette of a person with a star symbol. This icon indicates that the substance can cause serious health risks, including carcinogenicity, respiratory sensitization, reproductive toxicity, and other health-related dangers. It is crucial for communication regarding hazardous materials, as it alerts users to potential long-term health effects from exposure to the chemical in question.

In contrast, the other symbols represent different types of risks: the flame symbol denotes flammable substances, the skull and crossbones indicate acute toxicity, and the water droplet is used to signify environmental hazards. Each of these symbols conveys warnings about specific dangers, reinforcing the importance of understanding the GHS classification system to ensure proper handling and safety measures in the presence of hazardous materials.
