Which color indicates mandatory PPE signs?

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

Answer: (A)

Blue is used for mandatory PPE signs because blue conveys actions that must be taken. PPE signs show you the required equipment, and the blue background with a white pictogram makes it clear that you must wear that gear to stay protected. Yellow warns of hazards, green marks safe conditions or exits, and red signals prohibitions or fire equipment. So the color indicating mandatory PPE signs is blue.
