What does a signal word on a chemical label indicate?

A signal word on a chemical label indicates the potential severity of a hazard associated with the chemical. It serves to alert users to the level of danger presented by the material. For instance, signal words such as "Danger" or "Warning" are used to categorize the seriousness of health and physical hazards linked to the substance. "Danger" typically signifies a more severe hazard, while "Warning" indicates a lesser degree of hazard.

This system is part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), which aims to enhance safety by standardizing the way chemicals are classified and how information is communicated to users. Understanding the meaning of signal words is crucial for assessing risks and implementing appropriate safety measures when handling hazardous materials.

The other choices do not accurately represent the function of signal words. They may relate to other aspects of chemical safety and management, such as storage requirements or the origin of the chemical, but they do not pertain to the core purpose of signal words in hazard communication.
