What does the signal word on a label indicate?

The signal word on a label is an important part of communicating the level of hazard associated with a chemical. It serves to immediately alert users to the severity of the risks involved. The two signal words used in labeling are "danger" and "warning." "Danger" is used for more severe hazards, while "warning" indicates a less severe hazard.

This classification helps ensure that individuals working with the chemical are aware of the potential dangers and can take appropriate precautions. Signal words are a fundamental aspect of the Hazard Communication Standard (HCS) set forth by OSHA, as they enhance safety by providing clear, understandable information to anyone who may handle or be exposed to hazardous substances.

Other options do not accurately reflect the purpose of the signal word. For example, while a red diamond may be used in some labeling systems, it is not specifically indicative of the signal word. Similarly, while chemical labels include descriptions of use and storage, this information is separate from the signal word itself. Thus, the primary purpose of the signal word is to convey the degree of risk posed by the chemical.
