3.0 HARNESS USE
3.1 BEFORE EACH USE: Verify that your work area and Personal Fall Arrest System (PFAS) meet all criteria defined in
Section 2. Verify that a formal Rescue is in place. Inspect the Harness per the 'User' inspection points defined in the
"Inspection and Maintenance Log". If inspection reveals an unsafe or defective condition, remove the system from service
immediately. See Section 5 for inspection details. Do not use if inspection reveals an unsafe condition.
3.2 PLAN: Consider all factors that will affect your safety during use of this equipment. The following list gives important
points to consider when planning your system:
• Anchorage: Select an anchorage capable of sustaining the Static Load requirements of the intended fall protection
application (see Section 1.1). The anchorage location should address Free Fall, Fall Clearance, Swing Fall, and
Environmental limitations described in Section 1.4.
• Sharp Edges: Avoid working where system components may be in contact with, or abrade against, unprotected
sharp edges.
• After A Fall: If the Harness is subjected to the forces of arresting a fall or exhibits damage consistent with the effect
of fall arrest forces, it must be removed from service immediately. Clearly mark the Harness "DO NOT USE" and then
either destroy the Harness or contact 3M regarding replacement. See Section 4 and 5 for more information.
• Rescue: The employer must have a written, formal rescue plan when using this equipment. The employer must have
the ability to perform a rescue quickly and safely.
• Rescue Harness: Rescue Harnesses are intended to be worn during normal work activities. Before using rescue
attachment elements for the first time, the user should carry out a suspension test in safe conditions to ensure the
harness is sized and fitted for optimal comfort during suspension.
3.3 BUCKLES: Full Body Harnesses can be equipped with Duo-Lok™ Quick Connect Buckles for fastening and adjusting Leg
Straps and Chest Straps. Harness Body Belts have a Tongue Buckle. See Figure 1 for the buckle types on your Harness.
Figure 9 illustrates operation of each of the following buckles:
1. Duo-Lok™ Quick Connect Buckles:
A. To fasten the Duo-Lok Quick Connect Buckle, insert the Tab into the Receptor until a click is heard.
B. To adjust the attached Web Strap: Rotate the Webbing Lock to the Unlocked position
forward or backward through the Buckle Slot to tighten or loosen. After adjustment, rotate the Webbing Lock to
the Locked position.
;
The Webbing Lock does not lock or unlock engagement or disengagement of the buckle end. It only prevents or allows
passage of the excess Web Strap through the Buckle Slot.
C. To release the Duo-Lok Quick Connect Buckle: Squeeze the Lock Levers on each side of the Receptor. Pull the Tab
out of the Receptor.
2. Tongue Buckles: Fasten and adjust Tongue Buckles by passing the Tongue through the Buckle Frame and inserting
the Prong through the desired Grommet in the Tongue.
3.4 ADJUSTMENTS: Harnesses can be equipped with a pair of Revolver™ Torso Adjusters for adjusting the Shoulder Straps.
Figure 10 illustrates adjustment of the Revolver Torso Adjusters:
1. Revolver™ Torso Adjusters: To adjust the Shoulder Straps with the Revolver Torso Adjusters:
A. Rotate the Revolver Ratchet Knobs as illustrated in Figure 10 to tighten the Shoulder Straps.
B. Pull out and rotate the Revolver Ratchet Knobs as illustrated in Figure 10 to loosen the Shoulder Straps.
3.5 EASY-LINK™ ATTACHMENTS: Full Body Harnesses are equipped with a patented Easy-Link™ System that integrates
the Dorsal D-Ring with attachment elements for Harness-Mounted Self-Retracting Devices (SRDs). Figure 11 illustrates
attachment of the following 3M and Protecta Self-Retracting Devices: (A) 3M Nano-Lok™ Edge SRDs, (B) 3M Twin
Nano-Lok™ SRDs, (C) 3M Single Nano-Lok™ SRDs, (D) Protecta Twin Rebel™ SRDs, (E) 3M Twin Talon™ SRD. Other
manufactured SRDs can also be mounted on the Delta Harness in similar fashion. See the SRD manufacturer instructions
for requirements and installation instructions specific to the SRD.
;
Contact 3M with any questions or concerns regarding compatibility of your SRD with the Easy-Link System.
3.6 PUTTING ON AND FITTING THE FULL BODY HARNESS: Figure 14 illustrates putting on and fitting of the
Full Body Harness. Prior to each use, inspect the harness using the checklist on the "Inspection and Maintenance Log". To
put on and fit the harness:
;
Procedures for buckling and adjusting the straps on the Delta Harness will vary with the harness model. See Sections 3.3 thru 3.4
and Figures 9 thru 10 for details.
1. Lift up and hold the harness by the back Dorsal D-Ring. Ensure the straps are not twisted.
2. Grasp the Shoulder Straps and slip the harness onto one arm. The Dorsal D-Ring will be located on your back. Ensure
that the straps are not tangled and hang freely. Slip your free arm into the harness and position the Shoulder Straps
on top of your shoulders. The Chest Strap and Chest Buckle will be positioned on the front side when worn properly.
3. Reach between your legs and grasp the Leg Strap on your right side. Bring the strap up between your legs; buckle to
the mating receptor on you right hip, and adjust the Leg Strap for a snug, comfortable fit. When properly adjusted,
tuck the loose end of the Leg Strap under the Strap Keeper.
