What are the most common elements of a personal fall arrest system?

The correct choice identifies the components that are essential to a personal fall arrest system, which is specifically designed to protect workers who are at risk of falling from heights.

A personal fall arrest system includes a harness that fits securely to the body, allowing for safe attachment to other components and providing support during a fall. The lanyard connects the harness to an anchorage point, acting as a flexible line that can absorb the energy of a fall. The D Ring is the connection point on the harness to which the lanyard or other components secure, ensuring a direct tether to the fall protection system. Finally, the anchorage point is a stable point that supports the system, which might be a beam, truss, or another sturdy structure. Together, these elements work in unison to minimize the risk of injury in case of a fall, making it critical in construction and other industries where working from heights is routine.

In contrast, the other options describe safety gear and equipment that are important for overall personal safety in various situations but do not specifically pertain to the mechanics of fall arrest systems. They may enhance safety in different ways, like protecting from head injuries or ensuring visibility, but they do not function cohesively as a fall protection mechanism as outlined
