Which statement about GHS signal words is true?

• A. Danger and Warning signal words indicate the level of hazard severity on GHS labels.
• B. Danger and Warning indicate no hazard level.
• C. Only Danger is used on all safety labels.
• D. Signal words are not used on safety labels.

Answer: (A)

Signal words on GHS labels convey hazard severity. The two options, Danger and Warning, are used to communicate how serious a hazard is: Danger for more severe hazards, and Warning for less severe ones. This helps someone quickly judge the level of risk and the precautions needed, alongside pictograms and hazard statements that describe the specific danger. For example, a highly toxic substance might use Danger, while a mild irritant might use Warning. The statement is true because both signal words are intentionally used to indicate how severe the hazard is on the label. The other choices don’t fit: signal words do indicate hazard level, not none; both Danger and Warning are used—not just Danger on all labels; and signal words are indeed used on safety labels.
