Which statement correctly identifies the color used to indicate mandatory actions on safety signs?

• A. Red indicates danger.
• B. Blue indicates mandatory actions.
• C. Green indicates safety.
• D. Yellow indicates caution.

Answer: (B)

Safety signs use color to convey action you must take. Blue is reserved for mandatory actions, meaning you are required to do something—for example, wear PPE or perform a specific procedure. This color cue helps you act quickly and correctly in safety-critical situations. Red signals danger or prohibition, not a required action. Green marks safety or exit routes, not what you must do. Yellow indicates caution or warning. So identifying blue as indicating mandatory actions is the correct interpretation.
