What is the purpose of photoluminescent strips installed along the floor?

• A. Provide overhead lighting
• B. Act as escape path illumination
• C. Enhance cabin aesthetics
• D. Help with maintenance access

Answer: (B)

The purpose of photoluminescent strips installed along the floor is to act as escape path illumination. These strips are designed to glow in the dark, providing essential visibility in low-light or emergency situations, thereby guiding passengers and crew to the nearest exits. This is especially critical during an evacuation, where access to clear and visible escape routes can significantly enhance safety.

The design and placement of these strips ensure that passengers can easily identify the path they need to take without the aid of overhead lighting, which may not be reliable during emergencies. By providing continuous guidance in dark environments, these strips play a key role in ensuring safe egress from the aircraft.
