Which symbol is used on containers that may hold infectious materials?

• A. Biohazard symbol
• B. Radiation symbol
• C. Poison symbol
• D. Safety symbol

Answer: (A)

The main idea here is recognizing the warning symbol for biological hazards. Containers that may hold infectious materials are labeled with the biohazard symbol to alert anyone handling them to exercise precautions and use appropriate containment, PPE, and proper disposal procedures. This symbol is specifically designed to indicate biological risk such as blood, body fluids, cultures, or other materials that could spread disease.

The radiation symbol warns about radioactive hazards, not infectious material. The poison symbol indicates chemical toxicity, not a biological threat. A generic safety symbol is too broad to signal the specific risk of infectious materials.

So, the symbol used on containers that may hold infectious materials is the biohazard symbol.
