When shipping hazardous materials, what must be on the container?

• A. A four inch diamond shaped hazardous material label
• B. A circular safety sticker
• C. A blue stripe along the container
• D. No labeling is required

Answer: (A)

Hazardous materials must be clearly labeled so anyone handling or responding to an incident can recognize the danger quickly. The container needs a four-inch diamond-shaped hazard label that identifies the hazard class. This standardized label is designed for easy visibility and tells responders what type of hazard is inside (for example, flammable, toxic, corrosive). The other options don’t provide the required, standardized hazard information and would not meet regulations.
