Which color indicates a biosafety hazard or sharps container?

• A. Red
• B. Fluorescent orange
• C. Yellow
• D. Green

Answer: (B)

Color coding in safety labeling is used to quickly identify hazards and disposal streams. Fluorescent orange is chosen for biosafety hazards and sharps containers because it's highly visible and universally recognized as a warning for dangerous, puncture-prone waste. This makes it clear that items like needles and blades belong in puncture-resistant sharps containers and that the area and containers require careful handling and proper labeling. While other colors also mark different waste types in various facilities, the distinct orange shade is the standard cue for sharps and biosafety hazard waste.
