Which element is commonly standardized across safety signs to aid recognition worldwide?

• A. Language
• B. Color scheme
• C. Sound effects
• D. Power requirements

Answer: (B)

Colors are standardized on safety signs so they convey meaning instantly across languages and regions. The color scheme acts as a universal cue: red signals prohibition or danger, yellow warns of caution, blue indicates mandatory action, and green marks safety or exit routes. This global color coding helps people recognize the type of hazard or instruction even if they don’t understand the words or symbols. Language varies by country, and sound effects or power requirements aren’t part of a visual warning system, so they don’t provide the same universal recognition.
