Safe Work Restraint Practices at Height

Introduction: Hierarchy of Control

When working at height, the primary goal is to avoid such work whenever possible. However, if working at height is unavoidable, it is essential to follow the hierarchy of control to ensure safety. The next step after avoiding work at height is to use a work restraint system, which allows you to work close to an edge without the risk of falling.

Demonstrating Work Restraint Equipment

1. Identifying a Suitable Anchor Point

The first step is to identify a solid anchor point capable of supporting your weight. This anchor point must be secure and reliable. If the anchor point cannot directly accommodate a carabiner, use a slings to create a suitable attachment point.

2. Attaching the Sling and Carabiner

To set up the work restraint system:

• Wrap the sling around the anchor point and secure it.
• Feed the carabiner through the sling. Ensure it is a screw-gate carabiner and properly screw the gate to lock it in place.

This setup will allow us to simulate approaching an edge without the risk of falling. As our demonstration environment lacks a physical edge, we use a rope on the ground to simulate this edge.

3. Demonstrating Work Restraint

In this demonstration:

• Attach the equipment to the user (Jim) and ensure the gate on the carabiner is securely locked.
• Jim will walk towards the simulated edge (the rope) and use the restraint device by squeezing the handle to feed the rope through, allowing him to approach the edge safely.

When Jim reaches the desired position:

• If he releases the handle, the device will lock, preventing further movement.
• He must consider both the length of the lanyard and the rope when approaching the edge.

Jim can then perform his task without tension in the system. After completing the work, he will squeeze the handle to return along the rope away from the edge. Finally, he will move away from the edge and stow the equipment properly.

4. Additional Considerations

Depending on the specific task, it might be more advantageous to attach the work restraint equipment to your back fall arrest point rather than the front. This adjustment can offer greater freedom of movement while working.

Conclusion

By following these procedures, you can safely use work restraint systems and effectively manage risks associated with working at height.
