Fall protection
When workers are exposed to fall hazards while working at elevations of more than five feet, or over water, fall protection is required. Typically, guardrails or other barriers are used to protect workers. In situations where guardrails are not practical, or when working from two-point suspended scaffolding, personal fall arrest systems (PFAS) (such as safety harnesses, lifelines, lanyards) are required. In some situations, positioning device systems such as restraint (tether) lines or aerial lifts are used to provide protection from falling off an unguarded edge.
