Placards are used to identify hazard class. Which term completes the sentence: Each hazard class has a specific __________ that identifies the material's class?

Explanation:
Placards communicate hazard class to anyone handling or responding to a spill or accident. They are the standardized signs displayed on vehicles and packages that show the material’s class through a distinctive design and color scheme, so the hazard type can be identified at a glance. This is why the term that fits is placards. Serial numbers indicate identity, storage temperature signals conditions, and the manufacturer is about who produced the item, not the hazard class.
