Working at height presents real risks. Whether you’re managing a construction site, maintaining a rooftop or planning long-term access for maintenance crews, the right height safety system is critical, not just for compliance, but for keeping your team safe.
Two of the most common solutions are fall arrest systems and fall restraint systems. But while the names sound similar, they operate in very different ways.
In this guide, we break down the difference, when to use each one and how to make sure your system meets Australian safety standards.
A fall arrest system is designed to protect a worker who may fall. It doesn’t prevent the fall itself—it arrests it in progress, reducing the impact and preventing serious injury.
Typical components include:
These systems are used when workers need access to areas where a fall risk is unavoidable, such as working at the edge of a roof, climbing towers or servicing equipment on an elevated platform.
Fall arrest systems require a high level of planning. Workers must be trained in rescue procedures, and the system must allow for safe deceleration and clearance distance.
A fall restraint system is a preventive approach. It stops the worker from being able to reach the fall hazard in the first place.
This is typically achieved by:
Fall restraint systems are commonly used where the work area is predictable and where it’s possible to create a controlled zone. They are generally considered safer than fall arrest systems because they eliminate the fall risk altogether.
Both fall arrest and restraint systems must comply with the AS/NZS 1891 series, specifically:
According to AS/NZS 1891.4:
Failure to maintain these systems can result in non-compliance with WorkSafe requirements and put worker safety at risk.
Choosing between fall arrest and fall restraint depends on several factors:
If you’re unsure, the best place to start is with a site-specific assessment.
At The Lifting Guys, we provide tailored fall arrest and restraint system installations across:
We design systems to meet AS/NZS standards and WorkSafe requirements, ensuring your team is protected and your site remains compliant.
Both fall arrest and fall restraint systems are critical tools in modern height safety. Knowing when and how to use them correctly can be the difference between compliance and risk, and between a safe site and a serious incident.

Do fall restraint systems need to be inspected?
Yes. According to AS/NZS 1891.4, all fall protection systems, including restraint systems, must be inspected by a competent person at least every 12 months. Some components, such as lanyards and harnesses, may require inspection every 6 months, depending on usage and environmental conditions.
Are lanyards included in fall arrest systems?
Yes. Lanyards are a key part of many fall arrest systems, especially when used with shock absorbers and anchor points.
