How many foot candles should be provided in stairways and landings?

The standard for foot candles in stairways and landings is established to ensure adequate lighting for safety and visibility. A foot candle measures illumination and indicates how much light is emitted on a surface. Providing 20 foot candles in stairways and landings helps prevent accidents and enhances the safety of residents and visitors, allowing for clear visibility of steps and changes in elevation.

Adequate lighting in these areas is crucial because stairways can be hazardous, especially for individuals with mobility concerns. The recommended level of 20 foot candles balances sufficient visibility without excessive brightness that might cause glare or discomfort. This standard aligns with guidelines from various health and safety authorities, which are aimed at maintaining safe environments in healthcare and residential facilities.
