Which symbol on waste labels instantly identifies the kind of hazard the chemical possesses?

• A. Signal word
• B. Pictogram
• C. Precautionary statement
• D. Hazard statement

Answer: (B)

Pictograms are the symbols on waste labels that instantly identify the hazard type by using a standardized graphic for each hazard class. They’re designed to be quickly recognized and understood across languages, so you can tell at a glance whether a chemical is flammable, toxic, corrosive, or has another hazard. The other label elements are text-based and don’t convey hazard category visually: a signal word shows how severe the hazard is, precautionary statements outline safety steps, and hazard statements describe the hazard in words. For example, a flame pictogram signals flammability, while a skull-and-crossbones pictogram indicates acute toxicity.
