What is the requirement for foot candles in a janitor's closet?

In the context of lighting requirements for specific spaces within buildings, the standard for foot candles in a janitor’s closet is 15 foot candles. This standard is set to ensure that cleaning staff have adequate illumination to perform their duties safely and effectively. Adequate lighting in a janitor's closet is essential, as these spaces often contain cleaning supplies and equipment that workers need to access frequently.

While some areas may require more or less illumination depending on their use, the specified 15 foot candles for a janitor's closet balances safety and functionality. This requirement helps prevent accidents and allows staff to identify hazards or properly manage cleaning supplies.

The other choices reflect levels that do not align with established standards for janitorial spaces, either providing too much light, which may not be necessary, or too little, which could pose safety risks.
