Which description correctly defines a personal fall arrest system?

• A. It consists of an anchorage, connectors, and body harness only.
• B. It consists of a harness and rope only.
• C. It consists of an anchorage, connectors, and body harness, and may include a lanyard/deceleration device, lifeline, or combination thereof.
• D. It is any protective equipment worn while climbing.

Answer: (C)

A personal fall arrest system is a setup designed to stop a fall and limit injury, and it must include an anchorage point, connectors, and a body harness. It may also include a lanyard or deceleration device, a lifeline, or a combination of these to link the harness to the anchor and to arrest the fall. This combination of components is what defines a fall arrest system, with optional parts added to control fall distance and absorption of impact. The other descriptions leave out essential elements or are too vague: one omits the critical devices that actually arrest the fall, another misses the anchor or connectors, and a general statement about protective equipment isn’t specific to a fall-arrest system.
