What are placards?

• A. Labels with weights
• B. Hazardous signs and symbols
• C. Color codes only
• D. Emergency contact numbers

Answer: (B)

Placards are hazard signs and symbols posted on containers, vehicles, or storage areas to show the kind of danger inside. They use pictograms that represent the hazard class (like explosive, flammable, or toxic) and often include color and other markings, so anyone handling or responding to an incident can quickly identify the risk and take appropriate precautions. They’re not just weights on a label, nor are they limited to color codes or emergency contact numbers—placards focus on communicating the type of hazard.
