How to Properly Don and Adjust a Harness

Introduction to Donning a Harness

After completing the pre-use inspection of your harness, the next step is to don the harness correctly. This process involves putting the harness on the individual and adjusting it to ensure a secure and comfortable fit. Below, we will demonstrate the proper technique for donning and adjusting a harness.

Steps to Don a Harness

1. Opening and Initial Fit

Start by opening the harness fully. It is helpful to use a buddy system for this process. Ask your assistant to:

• Feed their arms through the harness loops.
• Turn around to face you for further adjustments.

Begin by fastening the harness from the top and work your way down. Ensure that all parts of the harness are connected, starting with the chest strap.

2. Adjusting the Waist and Leg Straps

Next, adjust the waist belt without tightening it yet. This will be done after the leg straps are properly adjusted.

For the leg straps, thread them through the legs and adjust them to fit snugly. Here are some key points to consider:

• Ensure the D-shaped fasteners are correctly positioned: the alteration strap should be on the outside for easier adjustment.
• Tighten the leg straps so you can slide your hands between the straps and your thighs without being able to move them away.

Adjust the straps by creating a loop at the top of the buckle and pulling the inside strap up, followed by tightening the outside strap to remove slack.

3. Positioning the Sternal Fall Arrest

The sternal fall arrest (front strap) should be positioned on the sternum, the central bone of the chest. Adjust the straps to pull this component up to the correct height, ensuring it is even on both sides.

4. Adjusting the Waistband

Fasten the waistband to ensure a comfortable fit around the waist. Use the plastic pieces on the belt to keep the buckle in place and prevent slack. Adjust until the waistband is secure and comfortable.

5. Checking Shoulder Fit

To check the fit on the shoulders, place two fingers under the shoulder straps. The harness should fit snugly if your fingers slide in without much resistance. A maximum of two fingers should fit comfortably; any more indicates the harness is too loose.

6. Inspecting the Dorsal Fall Arrest

Finally, check the dorsal fall arrest (back plate). It should be positioned between the shoulder blades to keep the body as vertical as possible in the event of a fall.

Conclusion

By following these steps, you can ensure that the harness is donned and adjusted correctly for maximum safety and comfort. Proper adjustment is crucial for the effectiveness of the harness during work at height.
