Hazmat containers must be labeled with what information?

• A. Volume
• B. Owner
• C. Date
• D. Appropriate warnings

Answer: (D)

Labels on hazmat containers are there to communicate hazards and the precautions that must be taken. The information should convey what the material is dangerous for (flammable, toxic, corrosive, reactive, etc.) and outline the necessary handling instructions, PPE, and basic emergency actions if a spill or exposure occurs. This guidance helps anyone who handles, stores, or responds to incidents to assess risk quickly and act safely. Details like volume, owner, or date may be relevant administratively or for inventory, but they do not provide the essential hazard information and safety instructions needed in day-to-day operations and emergencies.
