Work restraint systems are a type of fall prevention method designed to stop the user from reaching a fall hazard in the first place. When used correctly—and with proper training—this system physically prevents the user from moving into a position where a fall could occur.

In a typical restraint setup:

The length of the lanyard is adjusted to prevent access to edges or unprotected drop zones.

The worker remains connected to a secure anchor point at all times.

The goal is not to arrest a fall, but to stop it from ever happening.

Key components of a restraint system:

The fall hazard (e.g. an unprotected edge)

Harness – worn by the user

Anchor point – a secure fixing point to connect to

Lanyard or connection device – adjusted in length to prevent access to the hazard

Drop zone – the area the system is designed to restrict access to

Important considerations for safe work restraint:

Lanyard length
Ensure it is short enough that the user cannot reach the fall hazard. If the user can still reach the edge, then it is not true work restraint—it may become a fall arrest situation, requiring different safety measures.

Angles and Corners
Be aware of how movement around corners can unintentionally increase the lanyard’s effective reach. Users might inadvertently enter a danger zone due to slack in the system or change in angle. Always assess and control the working area.

Swing falls
Although restraint systems are designed to prevent falls, improper anchor placement (e.g. off to the side) can lead to a pendulum effect if a fall occurs unexpectedly.

Training
Proper training is essential. Users must understand how to inspect and adjust the equipment, how to assess risk areas, and how to properly connect to the system.

Work restraint systems are an effective and preferred way to prevent falls when used correctly. They form part of the "prevent" level in the Work at Height hierarchy, helping eliminate the need to rely on fall arrest systems.

Key points:

Work restraint prevents access to a fall hazard, rather than arresting a fall.

The system must be correctly set up and adjusted to be effective.

Be cautious of lanyard length, movement around corners, and anchor placement.

Training is essential for correct use and risk assessment.
