Exit signs are essential safety features found in buildings, indicating the nearest exit in case of an emergency. They are typically illuminated and marked with the word "EXIT" in bold letters, making them easily visible even in low-light conditions. These signs help guide people to safety during situations like fires or power outages. In many countries, regulations require exit signs to be placed in specific locations, ensuring they are accessible and clearly visible. The design and placement of exit signs are crucial for effective evacuation, as they help prevent confusion and panic during emergencies.
