What is the minimum illumination in foot-candles for the indoor corridors of construction areas?

The correct minimum illumination level for indoor corridors of construction areas is five foot-candles. This requirement is established to ensure that workers have sufficient lighting to navigate safely and effectively in potentially hazardous environments. Adequate lighting is critical in construction areas where visibility can be compromised due to various factors such as clutter, equipment, and other site-related obstacles.

Having a minimum of five foot-candles in corridors helps to reduce the risk of accidents by allowing workers to see their surroundings clearly, identify hazards, and move around safely, especially in areas where tools, materials, and moving machinery may pose additional risks. This standard is part of OSHA regulations aimed at maintaining safety on construction sites, highlighting the importance of proper illumination in maintaining a safe working environment.
