Which color is commonly used to designate the cold zone in barrier tape?

• A. Yellow
• B. Blue
• C. Green
• D. White

Answer: (A)

Color coding in barrier tape helps quickly communicate safety boundaries at an incident scene. The cold zone is the outer, non-hazard area where activities like staging, command post setup, and support work occur, away from the actual danger. Yellow tape is used to signal caution and to delineate that outer boundary, making it the best match for marking the cold zone. The other colors are typically reserved for different roles or zones (depending on the system), so they don’t consistently designate the cold zone in this convention.
