Is personal fall arrest system a fall prevention system?

A personal fall arrest system (PFAS) is not a fall prevention system; rather, it is designed to stop a person from falling after a fall has occurred. PFAS typically includes components like harnesses, lanyards, and anchorage points that work together to catch an individual and minimize the impact of a fall. In contrast, fall prevention systems aim to eliminate fall hazards and prevent falls from occurring in the first place, such as guardrails or safety nets.
