Which symbol indicates a toxic or poisonous chemical may be present?

• A. Biohazard symbol identifies a container for potentially infectious materials
• B. Radiation symbol warns about the presence of radioactive materials
• C. Poison symbol indicates a toxic or poisonous chemical may be present
• D. Cleaning agents are chemical compounds which remove deposits

Answer: (C)

Recognizing hazard symbols is essential for chemical safety. The poison symbol is used to warn that a substance is toxic or poisonous and can cause harm if it is inhaled, ingested, or absorbed through the skin. When you see this symbol, treat the material with caution: read the label and the safety data sheet, wear appropriate protective equipment such as gloves and goggles, work in a well-ventilated area, and store and dispose of the chemical according to the guidelines. In medical settings, you may encounter toxic cleaners, solvents, or reagents, so always assume potential toxicity and follow established safety procedures.

The biohazard symbol points to potentially infectious materials, the radiation symbol indicates radioactive materials, and the option about cleaning agents describes a category rather than a hazard symbol.
