Which area requires a minimum of 20 foot candles for adequate lighting?

Toilet facilities require a minimum of 20 foot candles for adequate lighting primarily because these spaces need to ensure safety, hygiene, and user comfort. Proper lighting in toilet facilities promotes better visibility, allowing individuals to navigate safely and use the amenities without risk of injury. Additionally, good lighting in such areas is critical for activities that require careful attention to detail, such as personal grooming and ensuring hygiene standards are met.

In contrast, while clinical offices, utility rooms, and medicine cabinets also require appropriate lighting for their respective uses, the specific demand for 20 foot candles is distinctly outlined for toilet facilities due to their public access and functions. Each of those other areas may have varying lighting requirements based on their purpose but do not universally stipulate this specific foot candle level as crucial for overall safety and functionality.
