Fall Arrest vs. Fall Restraint: What’s The Difference?

When working at heights, safety is paramount. Fall protection systems, such as fall restraint and fall arrest systems, are essential to prevent accidents and protect workers.

While these two systems may sound similar, they serve different purposes and are applied in various work environments. Understanding the difference between fall arrest and fall restraint can help in choosing the right protection for any job.

In workplaces where employees work above ground level, fall protection is a regulatory and practical necessity. Two primary systems in use are fall arrest and fall restraint. Both use harnesses, anchors, and other safety gear, but their applications and objectives differ significantly.

What is Fall Arrest?

Fall arrest is a safety system designed to stop a fall that is already in progress. This system is crucial when workers need to operate in areas where a fall hazard is present, and it may be unavoidable to access edges or unguarded spaces. Fall arrest systems include harnesses, lanyards, and anchor points that work together to catch a worker in the event of a fall, reducing the impact force and preventing contact with a lower level.

Key Components of Fall Arrest Systems:

  1. Full-body harness: Distributes the force of the fall across the body.
  2. Shock-absorbing lanyard or self-retracting lifeline: Reduces the sudden stop impact.
  3. Anchor point: Provides a secure attachment that can withstand fall forces.

In practice, fall arrest systems are intended as a last line of defense. They activate only if a fall occurs, which makes them essential in areas where workers must access unprotected edges or elevated workspaces. However, since these systems activate mid-fall, they require careful setup and regular inspection to ensure they perform correctly when needed.

What is Fall Restraint?

Fall restraint, on the other hand, prevents a fall from happening in the first place. It is a proactive system that restricts the worker’s movement, keeping them from reaching the edge or hazardous zone. Fall restraint systems are ideal when it is possible to limit access to areas with fall risks, such as rooftops or platforms with unprotected edges.

Key Components of Fall Restraint Systems:

  1. Full-body harness or belt: Provides a secure attachment point.
  2. Fixed-length lanyard: Keeps the worker at a safe distance from fall hazards.
  3. Anchor point: Acts as a stable connection point for the lanyard.

By keeping the worker within a designated area, fall restraint effectively removes the risk of a fall, making it preferable in situations where it can be practically applied. However, it does require a suitable setup where the movement can be adequately controlled within safe boundaries.

When to Choose Fall Arrest vs. Fall Restraint

Choosing between fall arrest and fall restraint systems depends on the work environment and the specific fall hazards involved. Fall restraint is the preferred option when feasible, as it prevents a fall rather than reacting to it. However, if the job requires workers to access areas where a fall cannot be avoided, fall arrest becomes essential.

For instance, roof maintenance on a building with no guardrails may use a fall restraint system to keep workers away from edges. In contrast, construction on open scaffolding may require fall arrest since workers may need to move closer to potential drop-offs.

Conclusion

Both fall arrest and fall restraint systems are critical for protecting workers at height, yet each serves a unique purpose. Fall arrest is reactive, catching workers during a fall, while fall restraint is preventative, keeping workers away from hazardous areas. Employers must evaluate their work environments to select the best system for each task, prioritizing safety and compliance with regulations. Proper training, equipment inspection, and adherence to safety protocols are essential for the effectiveness of both systems.
