What does a fall arrest system include?

A fall arrest system is designed to safely stop a person from falling by using various components that work together to minimize the risk of injury during a fall. The correct choice highlights the essential elements of such a system: harness, anchor, connector, and deceleration device.

The harness is worn by the worker and is crucial for distributing the forces of a fall across the body. The anchor is a secure point that the system is attached to, ensuring that it is stable enough to handle the forces exerted during a fall. Connectors, which often include carabiners, link the harness to the anchor point. The deceleration device is responsible for slowing down and stopping the fall, reducing the impact on the user.

By combining these components, a fall arrest system effectively protects workers from catastrophic injuries while working at heights, as it ensures a controlled stop rather than an abrupt halt that could lead to severe injury or fatalities.

In contrast, the other options do not encompass all necessary components for a fall arrest system. For example, a simple arrangement of rope, carabiner, and helmet lacks the vital elements of an anchor and a deceleration device, which are critical for arresting a fall safely. The mention of slings and a pulley also does
