What does a blue H&S sign mean?

• A. warning/hazard
• B. mandatory safety signs like PPE
• C. safety instructions like emergency exits or first aid
• D. prohibition signs

Answer: (B)

Blue signs in health and safety communicate that a specific action is mandatory. They tell you what you must do to stay safe, such as wearing PPE like safety glasses, hearing protection, or a hard hat. The blue circular format signals a required procedure or protective measure you are obliged to follow. By contrast, warning signs are yellow and alert you to potential hazards, safety instructions like emergency exits or first aid signs are green and point to locations or procedures, and prohibition signs are red and show what you are not allowed to do. So the blue sign best fits the idea of a required action you must take.
