What type of lighting is required for outdoor stairs in commercial buildings?

Adequate lighting to ensure visibility and safety is essential for outdoor stairs in commercial buildings to prevent accidents and provide a safe environment for users. The building code mandates that stairways, especially those that are outdoors and potentially less visible, are well-lit to avoid slips, trips, and falls.

Proper illumination helps users see the step edges clearly and gauge depth appropriately, especially in low-light conditions or inclement weather. This requirement is in place to enhance safety and ensure that all individuals, regardless of their physical abilities, can navigate the stairs without risk.

Other options do not meet the safety criteria established by building codes. For example, the absence of lighting would significantly increase the risk of accidents. Similarly, dim lighting does not provide the necessary visibility required for safe navigation, and relying solely on motion-sensor lights might lead to situations where the area remains unlit if no movement is detected, compromising safety.
