To ensure safety during demolition, what is one requirement for stairwells in multistory buildings?

Ensuring safety during demolition in multistory buildings often involves maintaining clear visibility in crucial areas, and this is why illumination of stairwells is a fundamental requirement. Proper lighting plays a significant role in preventing accidents by allowing workers and emergency personnel to see the steps and handrails clearly. This visibility is crucial, especially when navigating potentially hazardous areas or in emergency situations.

Moreover, well-illuminated stairwells help guide individuals to safety and prevent slips, trips, and falls, which are common causes of injuries in construction and demolition environments. This requirement reflects a broader commitment to safety standards, as adequate lighting is a key aspect of creating a secure workplace, especially in spaces where visibility might be compromised due to the ongoing demolition work.
