What are vertical barriers along the unprotected sides and edges of stairways used to prevent employees from falling to lower levels?

Vertical barriers along the unprotected sides and edges of stairways, often referred to as guardrails or safety barriers, are designed to prevent employees from falling to lower levels. These barriers help create a physical boundary that enhances safety by reducing the risk of accidental falls, especially in high-traffic areas. Additionally, they serve as a visual cue for workers to remain aware of their surroundings and the potential hazards associated with stairways. Proper installation and maintenance of these barriers are crucial for ensuring their effectiveness.
