What information must a chemical label include in a lab?

• A. The color of the container.
• B. Identity, hazard pictograms, signal word, hazard statements, precautionary statements, supplier, and date opened.
• C. Only the chemical name.
• D. The storage location.

Answer: (B)

Labels must convey essential safety and identification information so anyone handling the substance knows what it is and how to stay safe. The identity tells you exactly which chemical you’re dealing with, while hazard pictograms provide quick visual warnings about the types of hazards. The signal word (such as Danger or Warning) communicates the overall level of risk at a glance, and hazard statements describe the specific dangers the chemical poses. Precautionary statements guide you on how to prevent harm and what to do if exposure occurs. Supplier information links you to the source and safety resources, and the date opened helps track how long the container has been in use, which can affect stability, reactivity, or compatibility. This combination ensures you recognize hazards quickly, handle the material properly, and respond effectively in spills or exposures. The color of the container or merely knowing the chemical name does not provide the complete hazard and safety guidance, and storing location is not part of the required labeling information.
