TCFP Plans Examiner Practice Test

Illumination of exits must be continuous during occupancy and floors must be illuminated at not less than what foot candle measure?

1. 1 Foot Candle

2. 0.5 Foot Candle

3. 2 Foot Candle

4. 3 Foot Candle

The correct answer is: 1 Foot Candle

Illumination of exits is critical for ensuring safety during emergencies, as it helps guide occupants to safety. According to safety standards, such as those provided by the National Fire Protection Association (NFPA), the minimum illumination level for exit paths is set to ensure visibility without causing glare or disorientation. The requisite illumination level of 1 foot candle provides a balance that helps occupants navigate safely without overwhelming their vision. This standard is sufficient to ensure that signs, stairs, and other exit features are easily visible, contributing to more effective evacuation procedures. Other measures, such as 0.5 foot candle, may not provide enough illumination for clear visibility particularly in high-stress situations like evacuations. Hence, while 1 foot candle is the correct standard, lower levels would compromise safety during occupancy.
