Final answer:
In the GHS system, 'Danger' represents a higher hazard level than 'Warning.' 'Danger' is used for severe hazards, while 'Warning' is for less severe hazards.
Step-by-step explanation:
In the Global Harmonized System (GHS) of classification and labeling of chemicals, there are two signal words used to indicate the level of hazard associated with a substance: Danger and Warning. Danger represents the higher hazard level and is used for more severe hazards, while Warning indicates a less severe level of hazard. It's important to recognize these words and the associated hazard signs, such as the radioactive danger symbol, to ensure safety and proper handling of chemicals.
