Unprotected Edges of Elevated Work Surfaces

Unprotected edges include roof edges, roof/floor openings, structural steel edges, and leading edges. They are common to construction sites, so it is not surprising that one of the most frequently cited OSHA violations involving roofing and fall protection is unprotected sides and edges. Falls to a lower level are the major cause of fatalities in construction.

A leading edge is the edge of a floor, roof, or formwork for a floor or other walking or working surface (such as the deck), which changes location as additional floor, roof, decking, or formwork sections are placed, formed, or constructed. A leading edge is considered an "unprotected side and edge" when it is not actively and continuously under construction.

Each worker constructing a leading edge 6 feet or more above a lower level must be protected by guardrail systems, safety net systems, or personal fall arrest systems. The only exception is when the employer can demonstrate that it is infeasible or creates a greater hazard to use these systems. In that case, the employer must develop and implement a fall protection plan (discussed later in the course).

To be clear, workers must be protected by guardrail systems, safety net systems, or personal fall arrest systems—even if they are not engaged in leading edge work—if they are on a walking or working surface that is 6 feet or more above a level where leading edges are under construction.
