Which of the following best describes a restraint system?

A restraint system is designed specifically to prevent a worker from reaching a fall hazard. This means that such a system keeps the worker at a safe distance from edges or areas where a fall could occur, thereby helping to mitigate the risk of falling while working at heights. In this context, the primary role of a restraint system is to inhibit access to hazardous areas rather than to stop a fall that has already taken place, which is the function of a fall arrest system.

The other options address different aspects of safety, but they do not accurately define a restraint system. For instance, while enabling workers to reach their work area safely might be a necessary feature of general safety equipment, it doesn’t specifically relate to preventing access to fall hazards. Similarly, arresting a fall pertains to fall arrest systems instead, which deploy once a fall event has begun. Lastly, stating that a restraint system is for emergency situations overlooks the essential role it plays in proactive fall prevention during regular work conditions.
