Which bulk marking may be required for elevated temperature materials?

• A. The Word "HOT"
• B. The Word "COLD"
• C. Marine Pollutant Mark
• D. Owner's Name

Answer: (A)

The essential idea is hazard communication for materials shipped at a temperature that can cause burns. When a bulk shipment is elevated in temperature, a clear warning must be shown so handlers know to take precautions. The word HOT is used to indicate that the contents are hot and could burn skin or cause other heat-related hazards, so cooling or careful handling is required. This marking helps prevent injuries by immediately signaling heat risk to anyone touching or moving the container.

The other marks don’t convey this specific thermal hazard. "COLD" isn’t a standard hazmat mark for elevated temperatures, Marine Pollutant Mark relates to environmental risk, and the Owner's Name doesn’t communicate any hazard or handling instruction.
