What is the required foot-candle level for stairways and landings?

The required foot-candle level for stairways and landings is 20 foot-candles. Adequate lighting in these areas is crucial for safety, as stairs and landings can be high-traffic zones where individuals are likely to be moving quickly or carrying items that obstruct their view. Insufficient lighting can lead to accidents, making it imperative to maintain a minimum level of illumination.

This specific figure is established based on safety standards to ensure that individuals have clear visibility when navigating stairs and landings, reducing the risk of falls and injuries. A foot-candle measures the amount of light that falls on a surface. Therefore, the standard of 20 foot-candles reflects a balance between sufficient visibility and energy efficiency.

The other levels mentioned in the choices are either below or above this required standard, indicating that the standards set by various codes and regulations have determined 20 foot-candles as the optimal level for visibility in these critical areas. Thus, familiarity with these standards is essential for health facility administrators to ensure compliance and promote safety in their facilities.
