"علامت خروج" refers to the "exit sign" used in buildings to indicate the way out in case of emergencies. These signs are typically illuminated and strategically placed to ensure visibility, guiding people safely to exits during situations like fires or evacuations. In many countries, including ایران, the design and placement of exit signs are regulated by safety codes to enhance public safety. The signs often feature a green or red background with clear symbols or text, making them easily recognizable even in low-light conditions.
