Final answer:
Ammonium Nitrate is associated with an exclamation mark hazard class due to its potential for rapid combustion, while Sodium Hydroxide is corrosive, and Hydrogen Peroxide is an irritant. Sodium Chloride is non-hazardous.
Step-by-step explanation:
Among the examples given, Ammonium Nitrate would be classified with an exclamation mark hazard due to its ability to rapidly combust upon contact with other materials, making it a significant hazard. Sodium Hydroxide, also known as Caustic Soda, falls into the category of corrosive as it is a skin irritant that can cause severe burns. Hydrogen Peroxide is labeled as an irritant because it can cause irritation to the skin and eyes. Lastly, Sodium Chloride, commonly known as salt, is non-hazardous and safe for handling due to the stable nature of the ionic compound formed by sodium and chlorine.
