Emergency lighting shall provide ____ footcandles of illumination for a minimum of ___ hour(s).

Emergency lighting is a critical safety feature designed to ensure visibility during power outages or emergencies. According to the National Fire Protection Association (NFPA) and standards established by the Life Safety Code, emergency lighting should provide a minimum level of illumination to ensure the safe evacuation of occupants.

In this case, the requirement specifies that emergency lighting must deliver at least 1 footcandle of illumination. This level is deemed sufficient to allow individuals to navigate safely out of a building during an emergency situation. Additionally, the duration of illumination is specified to be a minimum of 1.5 hours, which ensures that lights remain operational long enough for most evacuation scenarios.

This particular choice aligns with the recognized standards for emergency lighting in various building codes and regulations, indicating a commitment to the safety and well-being of building occupants during emergencies.
