How many signal words are used in the GHS labeling system?

The Global Harmonization System (GHS) for labeling chemicals employs two signal words: "Warning" and "Danger." These signal words play a critical role in communicating the level of hazard associated with a chemical substance. "Danger" indicates a more severe level of hazard, while "Warning" denotes a less severe hazard. The use of these two signal words helps ensure that individuals handling chemicals can quickly assess the potential risks and take appropriate precautions, ultimately promoting safety in various environments, especially in workplaces dealing with hazardous materials.

Other options suggest one, three, or four signal words, which misrepresent the established guidelines of the GHS system. Understanding the significance of these two signal words is essential for ensuring effective hazard communication and safety practices.
