Emergency signs are visual indicators that communicate important information about potential dangers or urgent situations. These signs often use bright colors, symbols, and clear text to ensure they are easily recognizable. Common examples include fire exit signs, hazard warnings, and first aid symbols. They help guide people to safety and inform them about necessary actions during emergencies. In many places, emergency signs are standardized to ensure consistency and understanding across different regions and languages. For instance, the International Organization for Standardization (ISO) sets guidelines for safety signs, making it easier for individuals to respond appropriately in emergencies, regardless of their background or location.
