What elements are typically included on a hazard communication label?

• A. The chemical's price.
• B. The building address and phone number.
• C. The color of the label only.
• D. Pictograms, hazard statements, and precautionary statements.

Answer: (D)

Hazard communication labeling aims to quickly convey what could go wrong and how to prevent harm. The essential elements are pictograms, hazard statements, and precautionary statements. Pictograms use standardized symbols to show the type of hazard at a glance (flammable, toxic, corrosive, etc.). Hazard statements describe the specific risks in words (for example, “Causes skin irritation” or “May cause respiratory irritation”). Precautionary statements tell you what to do to prevent harm or lessen consequences (such as wearing protective gear, washing hands after handling, or storing away from heat). Together, these give a clear, actionable safety message on the label.

The other options don’t fit because they don’t convey hazard information: price is irrelevant to safety hazards; a building address and phone number aren’t hazard details; color alone doesn’t communicate the specific hazards or required precautions.
