What is the primary purpose of exit signs?

The primary purpose of exit signs is to indicate where to exit, guiding occupants safely and efficiently during an emergency. These signs are strategically placed in buildings to ensure that people can swiftly identify the nearest exit, which is crucial in situations where visibility may be compromised, such as during a fire or power outage. Properly illuminated and clearly marked exit signs help reduce confusion and panic, facilitating a quicker and safer evacuation. They are essential for meeting life safety codes and regulations, ensuring that occupants know the safest routes to leave the building in the event of an emergency. This is why the answer accurately reflects the fundamental role of exit signs in fire safety and building design.
