What does a signal word on a label indicate?

A signal word on a label is crucial as it communicates the level of hazard associated with a substance. Signal words such as "Danger" or "Warning" are used to indicate the severity of the risk; "Danger" suggests a higher level of risk, while "Warning" indicates a lower level of hazard. This immediate visual cue helps individuals quickly assess the potential danger posed by the material, enabling them to take appropriate precautions.

Understanding these signal words is essential for safety in handling substances, as they guide users in determining the necessary safety measures, personal protective equipment, and emergency procedures required when working with hazardous materials. This clear and immediate communication is vital in environments such as laboratories, where handling various substances is common.
