SAFETY INFORMATION
Please read, understand, and follow all safety information contained in these instructions prior to the use of this Self-Retracting
Device (SRD). FAILURE TO DO SO COULD RESULT IN SERIOUS INJURY OR DEATH.
These instructions must be provided to the user of this equipment. Retain these instructions for future reference.
Intended Use:
This Self-Retracting Device is intended for use as part of a complete personal fall protection system.
Use in any other application including, but not limited to, material handling, recreational or sports related activities, or other activities not
described in the User Instructions, is not approved by 3M and could result in serious injury or death.
This device is only to be used by trained users in workplace applications.
!WARNING
This Self-Retracting Device is part of a personal fall protection system. It is expected that all users be fully trained in the safe installation and
operation of their personal fall protection system. Misuse of this device could result in serious injury or death. For proper selection,
operation, installation, maintenance, and service, refer to these User Instructions including all manufacturer recommendations, see your
supervisor, or contact 3M Technical Services.
• To reduce the risks associated with working with an SRD which, if not avoided, could result in serious injury or death:
- Before each use, inspect the SRD and check for proper locking and retraction.
- If inspection reveals an unsafe or defective condition, remove the device from service and repair or replace according to the User
Instructions.
- If the SRD has been subjected to fall arrest or impact force, immediately remove the SRD from service and label the device ‘UNUSABLE’.
- Ensure the lifeline is kept free from any and all obstructions including, but not limited to; entanglement with moving machinery or
equipment (e.g., the top drive of oil rigs), other workers, yourself, surrounding objects, or impact from overhead objects that could fall
onto the lifeline or the worker.
- Never allow slack in the lifeline. Do not tie or knot the lifeline.
- Attach the unused leg(s) of the Harness Mounted SRD to the parking attachment(s) of the harness if equipped.
- Do not use in applications that have an obstructed fall path. Working on slowly shifting material, such as sand or grain, or within conned
or cramped spaces, may not allow the worker to reach sufcient speed to cause the SRD to lock. A clear path is required to assure
positive locking of the SRD.
- Avoid sudden or quick movements during normal work operation. This may cause the device to lock up.
- Ensure that fall protection systems/subsystems assembled from components made by different manufacturers are compatible and meet
the requirements of applicable standards, including the ANSI Z359 or other applicable fall protection codes, standards, or requirements.
Always consult a Competent and/or Qualied Person before using these systems.
• To reduce the risks associated with working at height which, if not avoided, could result in serious injury or death:
- Ensure your health and physical condition allow you to safely withstand all of the forces associated with working at height. Consult with
your doctor if you have any questions regarding your ability to use this equipment.
- Never exceed allowable capacity of your fall protection equipment.
- Never exceed maximum free fall distance of your fall protection equipment.
- Do not use any fall protection equipment that fails pre-use or other scheduled inspections, or if you have concerns about the use or
suitability of the equipment for your application. Contact 3M Technical Services with any questions.
- Some subsystem and component combinations may interfere with the operation of this equipment. Only use compatible connections.
Consult 3M prior to using this equipment in combination with components or subsystems other than those described in the User
Instructions.
- Use extra precautions when working around moving machinery (e.g. top drive of oil rigs) electrical hazards, extreme temperatures,

1.0 APPLICATIONS
1.1 PURPOSE: 3M Self-Retracting Devices (SRDs) are designed to be a component in a personal fall arrest system (PFAS). Figure 1 illustrates
SRDs covered by this instruction manual and their typical applications. They may be used in most situations where a combination of worker
mobility and fall protection is required (i.e. inspection work, general construction, maintenance work, oil production, conned space work,
etc.).
1.2 STANDARDS: Your SRD conforms to the national or regional standard(s) identied on the front cover of these instructions.
1.3 TRAINING: This equipment is intended to be used by persons trained in its correct application and use. It is the responsibility of the user to assure
they are familiar with these instructions and are trained in the correct care and use of this equipment. Users must also be aware of the operating
characteristics, application limits, and the consequences of improper use.
1.4 LIMITATIONS: Always consider the following limitations and requirements when installing or using this equipment:
• Capacity: This SRD has been compliance tested for use by one person with a combined weight (clothing, tools, etc.) from 130 lbs (59
kg) to 310 lbs (140 kg).1Make sure all of the components in your system are rated to a capacity appropriate for your application.
• Anchorage: Anchorages selected for fall arrest systems shall have a strength capable of sustaining static loads applied in the
directions permitted by the system of at least:
1. 5,000 lbs. (22.2 kN) for non-certified anchorages, or
2. Two times the maximum arresting force for certified anchorages.
When more than one fall arrest system is attached to an anchorage, the strengths set forth in (1) and (2) above shall
be multiplied by the number of systems attached to the anchorage.
;From OSHA 1926.500 and 1910.66: Anchorages used for attachment of personal fall arrest systems shall be independent of any
anchorage being used to support or suspend platforms, and capable of supporting at least 5,000 lbs. per user attached, or be designed,
installed, and used as part of a complete personal fall arrest systems which maintains a safety factor of at least two, and is under the
supervision of a qualied person. In Canada, refer to local regulations where applicable.
• Locking Speed: Situations which do not allow for an unobstructed fall path should be avoided. Working in confined or cramped
spaces may not allow the body to reach sufficient speed to cause the SRD to lock if a fall occurs. Working on slowly shifting material,
such as sand or grain,may not allow enough speed buildup to cause the SRD to lock. A clear path is required to assure positive locking
of the SRD.
• Free Fall: When used correctly, SRDs will limit the free fall distance to 2 ft. (61 cm). To avoid increased fall distances, do not work above the
anchorage level. Do not lengthen SRDs by connecting a lanyard or similar component without consulting 3M. Never clamp,
knot, or prevent the lifeline from retracting or being taut. Avoid slack line.
• Swing Falls: Swing Falls occur when the anchorage point is not directly above the point where a fall occurs. The force of striking an
object in a swing fall may cause serious injury (see Figure 3A). Minimize swing falls by working as directly below the anchorage point
as possible (Figure 3B). Working away from the anchorage point (Figure 3C) will increase the impact of a swing fall and increase the
required Fall Clearance (FC).
• Fall Clearance: Figure 3B illustrates Fall Clearance Calculation. Fall Clearance (FC) is the sum of Free Fall (FF), Deceleration Distance (DD)
and a Safety Factor (SF): FC = FF +DD + SF. D-Ring Slide and Harness Stretch are included in the Safety Factor. Fall Clearance values have
been calculated and are charted in Figure 4. A Safety Factor of .45m (1.5 ft) was used for all values in Figure 4.
Figure 4 illustrates Fall Clearance (FC) based on the Horizontal (H) and Vertical (V) distance between the dorsal SRD connection and
the anchorage point. Each horizontal grid line on the chart(s) represents vertical distance from the anchorage point. Each vertical grid
line represents horizontal distance from the anchorage point. The Fall Clearance value (FC) is determined by the zone (parabolic lines)
in which the Horizontal (H) and Vertical (V) grid lines intersect. The example in Figure 4 shows how to determine the required Fall
Clearance value (FC) for the stated Vertical (V) and Horizontal (H) distances.
;Variable Anchor Points: Fall Clearances in Figure 4 are based on a rigid, stationary anchor point. If anchoring to a Horizontal
Lifeline (HLL) or anchor point that can move, slide, or deform during a fall, the Fall Clearance values from Figure 4 will not
apply. Refer to the instructions for the HLL or anchor for additional details regarding required fall clearances, deections, and/or
deformation.
;Kneeling or Crouching: The Clearance Charts in Figure 4 assume the worker is in a standing position, with the SRD anchored
above the dorsal D-ring. If the worker will be kneeling or crouching, an additional 0.9 m (3 ft) of Fall Clearance is required.
;Never Anchor below the feet: Never connect to an anchorage point below your feet.
• Hazards: Use of this equipment in areas where surrounding hazards exist may require additional precautions to reduce the possibility of injury
to the user or damage to the equipment. Hazards may include, but are not limited to: high heat, caustic chemicals, corrosive environments, high
voltage power lines, explosive or toxic gases, moving machinery, or overhead materials that may fall and contact the user or fall arrest system. Avoid
working where your lifeline may cross or tangle with that of another worker. Avoid working where an object may fall and strike the lifeline; resulting
in loss of balance or damage to the lifeline. Do not allow the lifeline to pass under arms or between legs.
• Sharp Edges: Avoid working where the lifeline will be in contact with or abrade against unprotected sharp edges.
Where contact with a
sharp edge is unavoidable, cover the edge with a protective material.
1 Capacity: 130 lbs -310 lbs (59 kg- 140 kg) is the capacity range required by standard CSA Z259.2.2-17. Some 3M SRDs are tested to a 420 lbs (191 kg) capacity. See
Figure 1 for the SRD models covered by this instruction and their capacities.

2.0 USE
2.1 RESCUE PLAN: When using this equipment, the employer must have a rescue plan and the means at hand to implement it and
communicate that plan to users, authorized persons, and rescuers.
2.2 INSPECTION FREQUENCY: Per the Inspection Schedule (Table 2), SRDs must be inspected by a worker1before each use. SRDs must be
inspected by a Competent Person2at intervals determined from the Inspection Schedule. See the Inspection and Maintenance Log (Table 3)
for inspections procedures.
Repairable SRDs must be submitted to a 3M Authorized Service Agent for Revalidation Inspection at intervals determined from the
Inspection Schedule (Table 2).
The Authorized Service Agent will record their findings and label the product with the next annual service date.
Results of the Authorized Service Agent or Competent Person inspection should be recorded in the “Inspection and Maintenance Log” at the
back of these instructions or recorded with the Radio Frequency Identification (RFID) system (see Section 5).
2.3 NORMAL OPERATIONS: Normal operation will allow the lifeline to extend and retract with no hesitation or slack as the worker moves at
normal speeds. If a fall occurs, a speed sensing brake system will activate, stopping the fall and absorbing much of the energy created.
Sudden or quick movements should be avoided during normal work operation, as this may cause the SRD to lock up. For falls which occur
near the end of the lifeline travel, a reserve lifeline system or Energy Absorber has been incorporated to reduce the fall arrest forces.
2.4 BODY SUPPORT: A Full Body Harness must be used with the Self-Retracting Device. The harness connection point must be above the user’s
center of gravity. A body belt is not authorized for use with the Self-Retracting Device. If a fall occurs when using a body belt it may cause
unintentional release or physical trauma from improper body support.
2.5 COMPATIBILITY OF COMPONENTS: Unless otherwise noted, 3M equipment is designed for use with 3M approved components and subsystems
only. Substitutions or replacements made with non approved components or subsystems may jeopardize compatibility of equipment and may
affect safety and reliability of the complete system.
2.6 COMPATIBILITY OF CONNECTORS: Connectors are considered to be compatible with connecting elements when they have been
designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to inadvertently open regardless
of how they become oriented. Contact 3M if you have any questions about compatibility. Connectors (hooks, carabiners, and D-rings) must
be capable of supporting at least 5,000 lbs. (22.2 kN). Connectors must be compatible with the anchorage or other system components.
Do not use equipment that is not compatible. Non-compatible connectors may unintentionally disengage (see Figure 5). Connectors must
be compatible in size, shape, and strength. Self-locking snap hooks and carabiners are required. If the connecting element to which a snap
hook or carabiner attaches is undersized or irregular in shape, a situation could occur where the connecting element applies a force to the
gate of the snap hook or carabiner (A). This force may cause the gate to open (B), allowing the snap hook or carabiner to disengage from
the connecting point (C).
2.7 MAKING CONNECTIONS: Snap hooks and carabiners used with this equipment must be self-locking. Ensure all connections are
compatible in size, shape and strength. Do not use equipment that is not compatible. Ensure all connectors are fully closed and locked. 3M
connectors (snap hooks and carabiners) are designed to be used only as specied in each product’s user’s instructions. See Figure 6 for
examples of inappropriate connections. Do not connect 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 similar
objects which will result in a load on the gate if the hook or D-ring twists or rotates, unless the snap hook is equipped with a 3,600 lb (16 kN) gate.
C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor, and without visual
conrmation seems to be fully engaged to the anchor point.
D. To each other.
E. Directly to webbing or rope lanyard or tie-back (unless the manufacturer’s instructions for both the lanyard and connector specically
allows such a connection).
F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and lock, or that roll-out could occur.
G. In a manner that does not allow the connector to align properly while under load.

life and inspection requirements as provided in the manufacturer’s instructions.
1 Worker: Any person who is protected from falling by an active and/or passive fall-protection system, or in the case of a fall-arrest system, any person who might fall
while attached to the system.
2 Competent Person: An individual designated by the employer to be responsible for the immediate supervision, implementation, and monitoring of the employer’s
managed fall protection program who, through training and knowledge, is capable of identifying, evaluating, and addressing existing and potential fall hazards, and
who has the employer’s authority to take prompt corrective action with regard to such hazards

2.8 SELF-RETRACTING DEVICES WITH LEADING EDGE (SRD-LE): The SRDs covered by this instruction manual include
Self-Retracting Devices with Leading Edge capabilities (SRD-LEs). See Figure 1 for specic SRD-LE models. SRD-LEs were
tested for horizontal use and falls over a steel edge without burrs. SRD-LEs may be used in situations where a fall may
occur over steel edges, such as found on steel shapes or metal sheeting.
Leading Edge Precautions: Observe the following precautions when using SRD-LEs:
• Users over 310 lbs (140 kg) must not use this device in Leading Edge applications.
• The allowable angle of redirection of the lifeline portion of the SRD-LE at the edge over which a fall might occur
(measured between the two sides formed by the redirected lifeline) shall be at least 90 degrees (see Figure 7).
• The anchor point shall be situated at the same height as the edge at which a fall might occur or above the edge.
Anchor points below the edge are dangerous because they cause the lifeline to redirect at an angle sharper than 90
degrees (see Figure 7).
• Consult Section 1 for limitations to the allowable work area relative to the anchorage point, including factors such
as swing fall and abrasion on the line at the edge and the use of a single anchor point versus anchors that allow
horizontal movement (e.g., Horizontal Lifeline or Horizontal Rail).
• SRD-LEs may be used with a Horizontal Lifeline or Horizontal Rail only as instructed in the product instructions for the
Horizontal Lifeline or Horizontal Rail.
• Do not work on the far side of an opening opposite the SRD-LE anchorage point.
• In the event of a fall over the edge, special rescue measures may be required.
• When planning your Leading Edge application, be sure work area parameters are within the Minimum Setback
Distance, Maximum Free Fall Distance, and Minimum Fall Clearance Required when Falling Over an Edge as indicated
on the SRD-LE labeling.
• For straight line connections, the WrapBack SRD should only be attached to a rigid anchor point if used in a Leading
Edge application.
Leading Edge Fall Clearance Calculation: The Minimum Fall Clearance Required when Falling Over an Edge can be
calculated based on the Setback Distance and Distance Along the Edge of your Leading Edge application (see Figure 8). To
calculate Fall Clearance from the table in Figure 8:
1. Select the value closest to your Setback Distance (A) in the left-side row headings.
2. Select the value closest to your working Distance Along the Edge (B) from the top column headings. Shaded areas
with no values indicate the Distance Along the Edge is outside of the safe Work Radius for your selected Setback
Distance.
3. The Clearance Required when Falling Over an Edge (C) will be the value listed at the intersection of the row selected
in Step 1 and the column selected in Step 2.
;Ensure Anchor Height (D) meets the minimum distance stated for the user capacity.
4. Repeat the previous steps for every edge over which the worker could potentially fall to determine safe placement of
anchorage and allowable Work Radius.
CSA Z259.2.2-17 Deployment Calculation:
;Deployment: Deployment is equal to the Deployment Factor (Dm) times Free Fall Distance (h) for a Maximum
Worker Mass (kg) or deployment based on the results of Dynamic Testing specied in CSA Z259.17, Clause 7.2,
whichever is greater.
• Deployment Factor for a 141 kg mass (D141) = 1.1
• When SRD is anchored overhead Maximum Deployment Distance = 1.07 m (3.5 ft)
• When SRD is anchored so free fall is possible, Maximum Deployment Distance = 2.1 m (7 ft)
