How often must exit signs operate?

1. Only during business hours.

2. 24 hours a day, every day.

3. Only during emergencies.

4. Weekdays only.

The correct answer is: 24 hours a day, every day.

Exit signs must operate 24 hours a day, every day, to ensure consistent visibility and accessibility in emergencies. They are critical safety features that guide occupants to safety during a fire, power outage, or another emergency situation, regardless of the time or day. Having these signs illuminated continuously enhances the chances of occupants being able to locate exits quickly, thus minimizing risks during critical situations. Regular operation ensures that the exit signs are always functional and visible, and it helps to comply with safety regulations and building codes that mandate permanent illumination of exit signs. The other options suggest limitations on when exit signs need to function, which is insufficient for ensuring safety in all scenarios. Businesses and facilities that rely on only illuminated exit signs during specific hours or only during emergencies may create hazardous environments where occupants cannot easily navigate to safety when needed most.
