1.0 PRODUCT APPLICATION
1.1 PURPOSE: Full body harnesses provide users with the means to connect to Fall Protection systems. The attachment
elements of the full body harness serve as connection points for the connecting subsystem, which secures the user
to an anchorage point. Full body harnesses may be used for a variety of Fall Protection systems. System application
is determined by the make of your full body harness and the attachment elements present on your harness. See the
“Product Overview” and Figure 2 for a full list of Fall Protection applications available for your full body harness model.
1.2 STANDARDS: Your product conforms to the national or regional standards identied on the front cover of these
instructions. If this product is resold outside the original country of destination, the re-seller must provide these
instructions in the language of the country in which the product will be used.
;For more information on certication or conformance requirements, refer to the applicable standards and
regulations listed for your product (e.g. the ANSI/ASSP Z359 Fall Protection codes).
1.3 TRAINING: This equipment must be installed and used by persons trained in its correct application. These instructions
are to be used as part of an employee training program as required by national, regional, or local standards. It is the
responsibility of the users and installers of this equipment to ensure they are familiar with these instructions, trained in
the correct care and use of this equipment, and are aware of the operating characteristics, application limitations, and
consequences of improper use of this equipment.
1.4 RESCUE PLAN: When using this equipment and connecting subsystems, the employer must have a written rescue plan
and the means to implement and communicate that plan to users, authorized persons, and rescuers. A trained, on-
site rescue team is recommended. Team members should be provided with the equipment and techniques necessary
to perform a successful rescue. Training should be provided on a periodic basis to ensure rescuer prociency. Rescuers
should be provided with these instructions. There should be visual contact or means of communication with the person
being rescued at all times during the rescue process.
2.0 SYSTEM REQUIREMENTS
2.1 CAPACITY: The user capacity of a complete Fall Protection system is limited by its lowest-rated maximum capacity
component. For example, if your connecting subsystem has a capacity that is less than your harness, you must comply
with the capacity requirements of your connecting subsystem. See the manufacturer instructions for each component of
your system for capacity requirements.
2.2 CONNECTING SUBSYSTEMS: Connecting subsystems (self-retracting devices, energy-absorbing lanyards, lifeline
subsystems, etc.) must be suitable for your application. Refer to the subsystem manufacturer instructions for additional
information.
2.3 ENVIRONMENTAL HAZARDS: Use of this equipment in areas with environmental hazards may require additional
precautions to prevent injury to the user or damage to the equipment. Hazards may include, but are not limited to: high
heat, chemicals, corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp
edges, or overhead materials that may fall and contact the user or equipment. Contact 3M Technical Services for further
clarication.
2.4 EXTENDED SUSPENSION: A full body harness should not be used in extended suspension applications. Extended
suspension can cause suspension trauma. If the user is going to be suspended for an extended length of time, it is
recommended that some form of seat support be used. 3M recommends a seat board, suspension work seat, seat sling,
or a boatswain chair. Contact 3M Technical Services for more information.
2.5 COMPONENT COMPATIBILITY: 3M equipment is designed for use with 3M equipment. Use with non-3M equipment
must be approved by a Competent Person. Substitutions made with non-approved equipment may jeopardize equipment
compatibility and may affect the safety and reliability of your Fall Protection system. Read and follow all instructions and
warnings for all equipment prior to use.
2.6 CONNECTOR COMPATIBILITY: Connectors are compatible with connecting elements when the size and shape of either
component does not cause the connector to inadvertently open, regardless of orientation. Connectors must comply with
applicable standards. Connectors must be fully closed and locked during use.
3M Connectors (snap hooks and carabiners) are designed to be used only as specied in each instruction manual. Ensure
connectors are compatible with the system components to which they are connected. Do not use equipment that is non-
compatible. Use of non-compatible components may cause the connector to unintentionally disengage (see Figure 3). If
the connecting element to which a connector attaches is undersized or irregular in shape, a situation could occur where
the connecting element applies a force to the gate of the connector (A). This force could then cause the gate to open (B),
disengaging the connector from the connecting element (C).

9
2.8 MAKING CONNECTIONS: All connections must be compatible in size, shape, and strength. See Figure 4 for examples of
inappropriate connections. Do not attach snap hooks and carabiners:
A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate. Large-throat snap hooks should not be connected to standard-
size D-Rings or other connecting elements, unless the snap hook has a gate strength of 16 kN (3,600 lbf) or greater.
C. In a false engagement, where size or shape of the connector or connecting element is not compatible and, without
visual conrmation, would seem to be fully engaged.
D. To each other.
E. Directly to webbing or rope lanyard or tie-back material, unless the instruction manuals for both the lanyard and
connector specically allow such a connection.
F. To any object whose size or shape does not allow the connector to fully close and lock, or that could cause connector
roll-out.
G. In a manner that does not allow the connector to align properly while under load.
2.8 LANYARD PARKING ATTACHMENT: Figure 5 illustrates lanyard parking. The lanyard parking attachment is for
attaching the free end of a lanyard or harness-mounted Self-Retracting Device when not connected to an anchorage
connection point for purposes of Fall Protection. Lanyard parking attachments must never be used as a Fall Protection
attachment element on the harness for connecting a lanyard or Self-Retracting Device (A).
When not connected to an anchorage connection point, an unconnected lanyard leg must be properly parked on the
Harness (B) or secured in the user’s hands as in 100-percent tie-off applications (C). Free-hanging Lanyard Legs (D) can
trip the user or catch on surrounding objects resulting in a fall.

3.0 INSTALLATION
3.1 OVERVIEW: Full body harnesses are to be used as part of a Fall Protection system. Ensure each component of your Fall
Protection system is installed per the manufacturer instructions.
3.2 PLANNING: Plan your Fall Protection system before installation. Account for all factors that may affect your safety
before, during, and after a fall. Consider all requirements and limitations specied in these instructions.
A. ANCHORAGE: Select an anchorage capable of sustaining the static load requirements of the intended Fall Protection
application. See the manufacturer instructions for each component of your Fall Protection system for more information.
The anchorage location should address all requirements specied in these instructions.
B. SHARP EDGES: Avoid working where system components may be in contact with, or scrape against, unprotected
sharp edges and abrasive surfaces. All sharp edges and abrasive surfaces should be covered with protective material.
C. CONNECTING SUBSYSTEMS: Connecting subsystems used with the harness must be suitable for your system
application. See the Product Overview and Figure 2 for more information, as well as the manufacturer instructions for
your connecting subsystem.
D. HARNESS STRETCH: Some amount of harness stretch should be expected when using this product as part of a
Fall Arrest system during fall arrest. See “Table 1 – Product Specications” for how much harness stretch should
be expected when using this product. Harness stretch should be added to all fall clearance requirements for your
system, unless it is already accounted for by the connecting subsystem or another component. See the manufacturer
instructions of your connecting subsystem for more information on fall clearance requirements.
;Maximum harness stretch is determined by the applicable standard or regulation.
E. D-RING EXTENSIONS: When used, D-ring extensions increase fall clearance requirements by increasing the amount
of free fall present in the Fall Arrest system. The length of the D-ring extension must be added to all fall clearance
requirements as part of the system’s free fall value. If there is an upper limit for free fall within the system, then
system use must be adjusted to remain below that limit. See Table 1 for the length of your D-ring extension. See
the manufacturer instructions of your connecting subsystem for more information on free fall and fall clearance
requirements.
;Never use D-ring extensions in leading edge applications.
3.3 FASTENING BUCKLES: 3M Harnesses are equipped with a variety of Buckles for fastening and adjusting Leg Straps
and Chest Straps. See Figure 1 for the buckle types present on your harness. Figure 6 illustrates operation of each of the

3.7 INSTALLING A HARNESS-MOUNTED SRD: Harness-mounted SRDs are secured directly to harnesses by means of a
harness interface. Harness interfaces are a type of connector specially designed for this purpose. In general, there are
two types of harness interface: straight-pin and carabiner. Instructions for each style are provided below.
;Instructions may vary per harness interface model. For more information on how to use your harness interface, see
the manufacturer instructions for the harness interface or for the product it was provided with.
;Do not remove the backplate from the harness when installing a harness-mounted SRD.
A. STRAIGHT-PIN INTERFACE: Straight-pin harness interfaces include a locking pin for securing to the harness.
Straight-pin interfaces may be used with Single-SRD or Twin-SRD formats, depending on the harness interface used.
See Figure 11 for reference.
1. Press both Locking Buttons (A) on the front of your harness interface to open. With the Locking Buttons held
down, remove the Locking Pin (B) from the harness interface.
2. Thread the Locking Pin (B) behind both Harness Straps (C), capturing the straps as you reinsert the pin into the
harness interface. An audible click should be heard when the Locking Pins are reengaged.
3. Verify that the harness interface is secure and that both Harness Straps (C) are captured by the harness interface.
B. CARABINER INTERFACE: Carabiner interfaces are carabiners that function as harness interfaces. Carabiner
interfaces may be used with Single-SRD or Twin-SRD formats, although methods will vary slightly. See Figure 12 for
reference, which shows how to install the carabiner interface using a Twin-SRD format.
1. Open the Gate (A) of the carabiner interface. Slide the SRD (C) over the open Arm (B) of the carabiner. Then,
slide the SRD to the opposite side of the carabiner.
2. Hold the Gate (A) of the carabiner interface open, then slide the open Arm (B) behind and around both Harness
Straps (D), capturing the straps within the carabiner interface.
3. Thread the second SRD (E) onto the open Arm (B) of the carabiner interface. Then, release the Gate to close and
secure the carabiner interface.
4. Verify that the carabiner interface is secure and that both Harness Straps (D) are captured by the interface.
;For Single-SRD formats, only one SRD should be attached to the carabiner interface. In this format, the
carabiner interface may be secured as outlined above, or directly to your Dorsal D-ring instead. If securing to your
Dorsal D-ring, do not capture the harness straps.
Certain harness models covered in these instructions include additional features for securing harness-mounted SRDs. See
below for how these features should be used:
• INTERFACE LOOP: The Interface Loop (X) is part of the backplate for certain harness models. The Interface Loop
serves as a secure connection point for harness interfaces behind the harness straps. See Figure 13 for reference. To
connect to the Interface Loop, the user should route their harness interface or its locking pin through the Interface
Loop as part of capturing the harness straps.
3.8 DEPLOYING THE SUSPENSION TRAUMA STRAPS: Figure 14 illustrates deployment of the Suspension Trauma Straps.
In the event of a fall, the Suspension Trauma Straps should be used by the fallen worker to alleviate suspension trauma.
To deploy the Suspension Trauma Straps on your harness:
1. Locate the Suspension Trauma Straps (A) on your harness. The Suspension Trauma Straps should be located in a
zipped container on your front, near the two intersection points of the leg straps.
2. Deploy the Suspension Trauma Straps by opening the zipped compartments located on the containers’ sides. Guide
the Straps (B) out from within each container to a length long enough for you to stand upon. Bring the two Straps
together and secure them to each other by means of the Strap Hook (C).
3. Extend the connected Straps as necessary to create a length of webbing for you to stand upon. Press your heels upon
either side of the connection point and stand up straight. This should transfer a signicant amount of weight to the
user’s feet, diminishing the likelihood of suspension trauma.
3.9 REMOVING THE BACK AND SHOULDER PAD: The Back and Shoulder Pad may be removed from the harness for
cleaning or adjustment. The Back and Shoulder Pad of the harness is secured to the Harness by Velcro straps along each
leg of the harness. See Figure 15 for reference. To remove the Back and Shoulder Pad:
1. Disconnect the Velcro straps located at Positions X, Y, and Z along each leg of the harness. To remove, rst
disconnect the Top Strap (A) and then pull away the Bottom Strap (B).
2. After this is done, the Back and Shoulder Pad may be removed from the full body harness. To reattach the Back and
Shoulder Pad, simply follow the procedure in reverse.
3.10 REMOVING THE LEG PADS: The Leg Pads may be removed from the Harness for cleaning or adjustment. The Leg Pads
of the Harness are secured to the Harness by hook and loop straps along each leg of the Harness. See Figure 16 for
reference. To remove the Leg Pads:
1. Disconnect the hook and loop straps of the Leg Pad (X). To remove, rst disconnect the Top Strap (A) and then pull
away the Bottom Strap (B).
2. After this is done, the Leg Pad may be removed from the Full Body Harness. Repeat these steps to remove the other
Leg Pad, or follow the procedure in reverse to reattach the Leg Pad.
3.11 SECURING LANYARDS WITH LOOP ENDS: Some lanyards are designed to choke onto a web loop to provide a
compatible connection. Lanyards may be sewn directly to the web loop forming a permanent connection. Do not make
multiple connections onto one web loop, unless choking two lanyards onto a properly sized web loop. See Figure 9 for

15
reference. To choke a lanyard onto a web loop:
1. Insert the lanyard web loop through the web loop or D-Ring on the harness.
2. Insert the appropriate end of the lanyard through the lanyard web loop.
3. Pull the lanyard through the connecting web loop to secure.
3.12 CONNECTING SYSTEM COMPONENTS: After donning the harness, the user may connect to their Fall Protection
System. Observe all requirements as specied in these instructions and any manufacturer’s instructions included with the
