What Must Be Printed on a Hazard Placard and NOT on a Hazard Label?

• A. The Printing ID #
• B. The Material Name
• C. The Shipping Destination
• D. The Quantity

Answer: (A)

The key idea is that placards are meant to identify the material to emergency responders from a distance, so they carry a universal four-digit identification number (the UN/NA ID). This ID lets responders look up the exact substance in the Emergency Response Guidebook and know what actions to take. Hazard placards include the hazard symbol, class, and that ID number, making it easy to recognize the material quickly. Hazard labels, by contrast, are smaller signs on individual packages and focus on the hazard class and packaging details rather than providing the precise material identity. They don’t standardly include the UN identification number, and information like the shipping destination or the quantity isn’t part of what a label communicates. So the element that must be printed on a hazard placard and not on a hazard label is the four-digit identification number—the Printing ID.
