Which waste uses a yellow bag with black stripe?

• A. Yellow bag with black stripe
• B. Yellow bag
• C. Orange bag
• D. Cytotoxic waste

Answer: (A)

Color-coding helps staff quickly identify how to handle and dispose of different wastes. A yellow bag with a black stripe is the signal for infectious clinical waste—material that may be contaminated with pathogens or body fluids and can cause infection. Because of this risk, it’s treated specially, often requiring sterilization or incineration and strict handling procedures. A plain yellow bag doesn’t carry that specific infectious warning, so it isn’t automatically designated for infectious waste. An orange bag is typically used for cytotoxic or hazardous pharmaceutical waste, which needs different precautions. Cytotoxic waste itself isn’t represented by a yellow bag with a black stripe.
