Which of the following is a common type of fall protection used in rigging?

Harness and lanyard systems are a common type of fall protection used in rigging because they provide a secure means of connecting a worker to an anchorage point. The harness fits around the body, distributing fall forces across the body more evenly, which minimizes the risk of injury in the event of a fall. The lanyard connects the harness to an anchoring point and often includes features such as shock absorbers to reduce the impact of a fall.

The effectiveness of harness and lanyard systems in preventing falls makes them a standard choice in various rigging operations, especially where the risk of falling from heights is significant. This system allows for more mobility and flexibility, enabling workers to perform their tasks while remaining securely attached and protected from falls.

In contrast, while guard rails, protective helmets, and safety nets also contribute to the safety of workers on job sites, they are not as directly associated with providing personal fall restraint or prevention in the same manner as harness and lanyard systems. Guard rails serve as passive fall protection barriers, while safety nets are primarily used to catch individuals who might fall, and helmets protect against head injuries rather than preventing falls themselves.
