What color sign indicates that supplies are not in use?

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

Answer: (B)

The correct choice indicates that yellow signs are generally used to convey a message of caution and awareness. In the context of supplies not being in use, a yellow sign signals individuals to be aware that although items are present, they are not actively in use or may require attention before being utilized. This color helps maintain a clear communication of status, ensuring that staff can recognize which supplies need to be handled carefully or are temporarily inactive. Understanding the role of color in signage is crucial in environments like plasma donation centers, where clear communication can affect safety and operational efficiency. Yellow, by being less alarming than red yet still eye-catching, serves as an effective warning or status indication without suggesting immediate danger. This distinguishes it from colors like red, which typically signals emergencies or stop, or green, which often indicates go or safe conditions.
