What does a red H&S sign mean?

What does a red H&S sign mean?

• A. Prohibition like no smoking
• B. Warning
• C. Mandatory
• D. Information

Answer: (A)

Red signs indicate prohibited actions. In health and safety signage, the color red is used to signal that you must not do something in that area—preventing dangerous situations by making the restriction instantly obvious, even from a distance. A common example is no smoking, where the cigarette symbol is crossed out inside a red circle. By contrast, yellow signs warn of hazards, blue signs denote required actions, and blue/green information signs provide safety information. So the red sign is about prohibitions, not warnings, mandatory actions, or information.
