What information must hazard placards and labels convey, and what does a Class 3 label indicate?

• A. They communicate hazard class, potential risks, and handling requirements; Class 3 indicates flammable liquids.
• B. They indicate shipping origin only.
• C. They indicate the color of the container.
• D. They communicate the shipper’s logo.

Answer: (A)

Hazard placards and labels are meant to communicate essential safety information for anyone handling or responding to a shipment. They convey the hazard class, the specific risks associated with the material, and the handling and safety precautions that must be followed to prevent accidents. The Class 3 label denotes flammable liquids, signaling that the material can ignite easily and requires measures to prevent ignition, such as avoiding open flames, ensuring proper ventilation, and using appropriate containment and storage practices. This labeling helps workers and responders choose the right PPE, fire-fighting approaches, and emergency procedures. The other options don’t fit because shipping origin, container color, or logos don’t communicate the danger or the required safety actions.
