Work Restraint Using Dorsal Attachment Explained

Work restraint systems are designed to prevent falls but how they’re set up makes all the difference.

In some situations, using a dorsal (rear) attachment point can provide a practical solution. However, it requires careful control of slack, positioning, and anchor selection to ensure the system works as intended.

In this video, we break down how dorsal attachment restraint works and what to consider when applying it on site.

The core principle of work restraint remains the same, regardless of the attachment point:

You should never be able to reach a position where a fall can occur.

When using a dorsal attachment:

• The system must still prevent access to the edge
• The user must remain under control at all times
• Slack must be actively managed

Unlike fall arrest systems, restraint relies on positioning and restriction, not stopping a fall after it happens.

This makes correct setup critical.

Practical Steps / Key Takeaways

When using work restraint from a dorsal attachment:

• Ensure the anchor point is suitable and prevents access to the edge
• Use an extension strop if needed to improve control and usability
• Keep the system under tension — avoid slack at all times
• Adjust the system as you move to maintain safe positioning
• Be aware of multiple edges or corner risks
• Ensure the anchor cannot move or slide into a dangerous position
• Always work in a way that prevents reaching a fall position

A key risk is allowing slack into the system, which can unintentionally introduce fall potential.

Dorsal attachment in restraint isn’t always the first choice but in the right situation, it can be effective.

The decision should always come back to:

• The task being carried out
• The available anchor points
• The working environment

We often see restraint systems set up without fully considering how the user will move and work within that system.

This is where risk is introduced.

At REAX, we focus on real-world application, not just what works in theory, but what works safely and practically on site.

That includes understanding when different attachment points are appropriate, and how to manage them correctly.
