Which color in TBI Thor is used to indicate caution?

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

Answer: (A)

Color-coding on TBI Thor uses a simple risk scale to communicate how much caution you should exercise. Yellow signals caution: hazards may be present, so you should slow down, scan carefully, and proceed deliberately with heightened awareness. It indicates you need to verify actions and safety steps rather than rushing or stopping outright. Green means conditions are safe to proceed normally, orange points to a higher level of risk requiring increased vigilance and preparation, and red denotes immediate danger requiring decisive action or withdrawal. So Yellow is the best choice because it conveys the need for careful consideration without the immediacy of stopping or the urgency of a higher warning.
