Which statement about container labeling is true?

• A. All containers must be properly labeled with waterproof labels listing substance name, trade name, manufacturer, hazards, and date
• B. Only the substance name
• C. The color and shape of the container
• D. Labels are optional

Answer: (A)

Labels on containers provide the essential information needed for safe handling, storage, and regulatory compliance. The statement that all containers must be properly labeled with waterproof labels listing the substance name, trade name, manufacturer, hazards, and date is the best because it gives a complete, actionable picture: the substance inside, any alternate name used in documentation, who produced it for source or recalls, the specific hazards to guide PPE and procedures, and the date to manage shelf life or opening history. Waterproof labels stay legible in moist or challenging environments, so the information remains available during spills or routine use. Without this full labeling, you risk misidentification, wrong safety measures, improper storage, or failing to meet safety regulations. Relying only on the substance name omits critical details like hazards and handling implications. Assuming the container’s color or shape reliably indicates its contents is not safe, since appearances can be misleading and many materials share similar packaging. Labeling being optional would remove a key safety barrier and is not consistent with proper safety practices.
