Emergency exit signs are crucial safety features in buildings, indicating the nearest exit in case of an emergency. These signs are typically illuminated and designed to be easily visible, even in low-light conditions. They often feature a green background with a white pictogram of a person walking towards an exit. The placement of emergency exit signs is strategic, ensuring that they are seen from various angles and distances. They are required by safety regulations in many countries, including guidelines from organizations like the Occupational Safety and Health Administration (OSHA). Properly functioning exit signs can help guide people to safety during emergencies.
