Final answer:
Hazard statements describe the hazards of a chemical, while precautionary statements provide guidance on handling and exposure measures.
Step-by-step explanation:
When it comes to the Global Harmonized System (GHS) classification of chemicals, there is a difference between hazard statements and precautionary statements.
Hazard statements are standardized phrases that describe the nature of the hazards posed by a chemical. These statements provide information about the physical, health, and environmental hazards associated with the chemical. For example, a hazard statement might indicate that a chemical is flammable or toxic.
Precautionary statements are also standardized phrases, but they focus on measures to be taken to minimize or prevent adverse effects from exposure to a chemical. These statements provide guidance on how to handle, use, store, and dispose of the chemical safely. They also include information about personal protective equipment that should be used and first aid measures to be taken in case of exposure.
