Which component is NOT typically part of a personal fall arrest system?

A personal fall arrest system (PFAS) is designed to safely stop a person from falling during work at heights. It consists of several critical components, including a body harness, deceleration device, and anchorage.

The body harness is essential as it distributes forces over the body in the event of a fall, ensuring the worker is secured appropriately. The deceleration device plays a vital role in reducing the forces experienced during a fall, either through shock-absorbing lanyards or self-retracting lifelines. The anchorage serves as the secure connection point for the fall arrest system, designed to withstand the forces exerted during a fall.

A guardrail system, while an important fall protection measure, is not classified as a component of a personal fall arrest system. Guardrails create a physical barrier to prevent falls from elevated work surfaces but do not function in the same capacity as a PFAS. Therefore, identifying the guardrail system as not being part of a personal fall arrest system demonstrates an understanding of the distinctions between different fall protection methods in construction safety.
