What is the minimum foot candle level required for illumination during occupancy?

1. 0.5 foot candle

2. 1 foot candle

3. 2 foot candle

4. 3 foot candle

The correct answer is: 1 foot candle

The minimum illumination level required during occupancy is set at 1 foot candle. This standard is established to ensure that occupants can safely navigate spaces, undertake tasks, and identify hazards effectively in a variety of environments. Adequate lighting is crucial for safety, especially in emergency situations where visibility is critical. Illuminating a space to a level of 1 foot candle allows for a balance between sufficient visibility and energy efficiency. Levels lower than this, such as 0.5 foot candle, would likely not provide enough light for occupants to see clearly, increasing the risk of accidents and making it difficult to perform everyday activities safely. Therefore, maintaining an illumination level of at least 1 foot candle is essential for ensuring both safety and functionality in occupied areas.
