Which of the following best describes labeling of biohazards involving materials such as hypodermic needles and bloodstained clothing?

• A. Hypodermic Needles
• B. Bloodstained Clothing
• C. A and B
• D. Gunshot Residue

Answer: (C)

Labeling of biohazards is about warning that an item may contain infectious material. Hypodermic needles and bloodstained clothing both can carry bloodborne pathogens, so they should be labeled as biohazards to alert responders and ensure proper handling, PPE, and disposal. Gunshot residue, meanwhile, is a chemical residue rather than a biological contaminant, so it isn’t classified as a biohazard in the same way. Therefore, marking both needles and bloodstained clothing as biohazards best reflects the potential biological risk.
