more information on system applications.
1.2 StanDarDS: This instruction manual applies to the harness models listed in Table 1. Harness models are grouped
in Table 1 per the status of their NFPA certification. For more information on the NFPA standard, refer to the life safety
harness information found in NFPA 1500 ("Standard on Fire Department Safety and Health Program") and NFPA 1983

all straps are not twisted.
2. With the front of the harness facing forward, step through the right side of the harness with your right leg. Then, step
through the left side of the harness with your left leg. Grasp the right shoulder strap and place it on the top of your
right shoulder. Ensure that the straps are not tangled and hang freely.
3. Grasp the left shoulder strap and place it over your left shoulder. The two D-rings will be positioned on the front of your
body if the harness has been donned properly.
4. Grasp the tab of the buckle located at the bottom of the strap that you placed over your left shoulder. Insert the tab
into the receptor of the quick connect buckle on the left side of the harness. You will hear a click when the tab engages

from the waist strap and the strap is comfortably tight around your waist. Insert strap ends into the waist strap keeper
loops on the right and left sides of the harness.
