Which area requires the lowest foot-candle level?

The area that requires the lowest foot-candle level is the utility room. The primary function of a utility room is to store equipment and supplies, which generally do not require high levels of illumination to ensure safety and visibility. Unlike areas such as corridors and stairways, where higher foot-candle levels are critical for safe passage and navigation of individuals, utility rooms are often not frequented by personnel and do not serve as primary thoroughfares. This allows for a lower standard of lighting, as tasks performed in these spaces typically do not require detailed visual acuity. The lower foot-candle requirement balances the need for visibility with the practicality and efficiency of maintaining adequate lighting levels in less trafficked areas.
