Biomedical waste bag color is?

• A. Red with biohazard symbol
• B. Blue with wave symbol
• C. Yellow with biohazard symbol
• D. Green with medical cross

Answer: (A)

Color-coding and labeling biomedical waste bags communicates danger and guides safe handling. The red bag with the biohazard symbol is the standard indicator for infectious or regulated medical waste. This tells staff that the contents are contaminated with blood or other potentially infectious materials and must be handled, stored, and disposed of through approved medical-waste channels, not with regular trash. The bold red color and the biohazard icon provide immediate recognition, reducing the risk of exposure for others and ensuring compliance with disposal rules. Other colors may be used for different waste streams in some settings, but they do not universally signify infectious waste like red with the biohazard symbol does.
