What type of exit sign is typically required in buildings?

Illuminated exit signs are typically required in buildings to ensure visibility and safety during an emergency. These signs are designed to be easily seen from a distance and under various lighting conditions, including low-light or smoke-filled environments. The illumination helps prevent confusion and guides occupants toward the nearest exit efficiently when they may need to evacuate quickly.

In many building codes and safety regulations, illuminated exit signs are mandated to provide consistent and reliable visibility. They often feature a green or red glow and may operate on a battery backup system to ensure functionality even during power outages. The use of illuminated exit signs plays a crucial role in maintaining a safe environment, particularly in commercial and public buildings where large crowds may gather.

Other types of exit signs, such as non-illuminated, temporary, or directional signs, do not provide the same level of visibility or reliability required in emergency situations, making illuminated signs a vital component in fire safety planning and compliance.
