DESCRIPTION:

Figure 2 identies key components of the DBI-SALA® Ultra-Lok™ Self-Retracting Devices (SRDs). Ultra-Lok SRDs are drum

wound Wire Rope Lifelines (A) which retract into a sealed aluminum Housing (B). They can hang from anchorage by a Carabiner

attached through the Swivel Eye (C) on the top of the SRD. A Self-Locking Snap Hook (D) on the end of the Lifeline attaches to

the designated Fall Arrest connection on a Full Body Harness. A Bumper (E), protects the Wire Rope and Ferrules securing the

Snap Hook from abrasion and corrosion.

Figure 1 denes the Ultra-Lok SRD models covered by this instruction manual. The following SRD Types are available:

• Self-Retracting Device (1): Self-Retracting Devices (SRDs) are suitable for applications where the lifeline remains

generally vertical during use and possible Free Fall is limited to 2 ft (0.6 m).

• Self-Retracting Device with Rescue (2): Self-Retracting Devices with Rescue include an integral means for assisted

rescue by raising or lowering the rescue subject. RSRDs are equipped with a 3-Way Emergency Retrieval Hand Crank

(F). Some models include a Tripod Mounting Bracket (G) to mount the SRD on the leg of a Tripod for Conned Space

applications.

1.0 APPLICATIONS

1.1 PURPOSE: 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. 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. Refer to the local, state, and federal (OSHA) requirements governing occupational safety for additional

information regarding Personal Fall Protection.

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 when installing or using this equipment:

• Capacity: SRDs are for use by one person with a combined weight (clothing, tools, etc.) meeting the Capacity Range

specied in Figure 1 for your standard(s). Make sure all of the components in your system are rated to a capacity

appropriate to 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 1926.502 AND 1910.140: 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.

• 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: Properly using an SRD in overhead applications will minimize free fall distance. To prevent an increased free fall

distance, follow the instructions below:

• Never clamp, knot, or otherwise prevent the lifeline from retracting or staying taut.

• Avoid any slack in the lifeline of the SRD.

• Do not work above the level of your anchorage.

• Do not lengthen SRDs by connecting a lanyard or similar component without consulting 3M.

For product-specific information relating to free fall and fall clearance values, please refer to Table 1 of this

instruction.

• 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).

• 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 1.5 ft (0.45 m) was used for all values in Figure 4.

For falls from a standing position where the SRD is anchored directly overhead (Figure 3B), SRD Fall Arrest Systems

should have the minimum Fall Clearances specied in Table 1. Falls from a kneeling or crouching position will require

an additional 1 m (3 ft) of Fall Clearance. In a swing fall situation (Figure 3C), the total vertical fall distance will be

greater than if the user had fallen directly below the anchorage point and may require additional Fall Clearance.

Figure 4 and the accompanying table dene the Maximum Work Radius (C) for various SRD Anchorage Heights (A)

and Fall Clearances (B). The Recommended Work Zone is limited to the area located within the Maximum Work

Radius.

• 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 using this equipment where system components will be in contact with, or scrape against,

unprotected sharp edges and abrasive surfaces.

2.0 Use

2.1 FALL PROTECTION AND RESCUE PLAN: The employer must have a Fall Protection and Rescue Plan in place that meets

ANSI Z359.2 Minimum Requirements for a Comprehensive Managed Fall Protection Program. The plan should provide

guidelines and requirements for an employer’s managed fall protection program, including policies, duties and training;

fall protection procedures; eliminating and controlling fall hazards; rescue procedures; incident investigations; and

evaluating program effectiveness.

2.2 INSPECTION FREQUENCY:

SRDs shall be inspected by the authorized person1or rescuer2before each use (See Table

3). Additionally, inspections shall be conducted by a competent person3other than the user. Extreme working conditions

(harsh environment, prolonged use, etc.) may necessitate more frequent competent person inspections. The competent

person shall use the Inspection Schedule (Table 2) to determine appropriate inspection intervals.

Inspection procedures

are described in the Inspection & Maintenance Log (Table 3). Results of the Competent Person inspection should be recorded

in the Inspection and Maintenance Log or recorded with the Radio Frequency Identification (RFID) system.

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 size or shape of the mating connectors are not compatible and, without visual

conrmation, the connectors seem fully engaged.

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.

1 Authorized Person: A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard.

2 Rescuer: Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.

3 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.

3.0 Installation

3.1 PLANNING: Plan your fall protection system before starting your work. Account for all factors that may affect your safety

before, during, and after a fall. Consider all requirements and limitations dened in this manual.

3.2 ANCHORAGE: Figure 7 illustrates typical SRD anchorage connections. The anchorage (A) should be directly overhead to

minimize Free Fall and Swing Fall hazards (see Section 2). Select a rigid anchorage point capable of sustaining the static

loads dened in Section 1.4. The Swivel Eye on the SRD is equipped with a Carabiner (B). Attach the Carabiner directly to

the anchorage structure (rebar, angle iron, etc.), or a Tie-Off Adaptor (C). Some industries require a secondary Dropped

Object Anchorage (D) to prevent the SRD from dropping if the primary anchorage point fails.

3.3 HARNESS CONNECTION: A Full Body Harness is required for Fall Arrest applications. Connect the Snap Hook (A) on

the SRD Lifeline to the back Dorsal D-Ring (B) on the Full Body Harness. (see Figure 8). For situations such as ladder

climbing, it may be useful to connect to the front Sternal D-Ring. Consult the harness manufacturer’s instructions for

details regarding use of the harness connection points.

3.4 TRIPOD MOUNTING: Figure 9 illustrates installation of the Ultra-Lok Self-Retracting Device with Retrieval Hand-Crank

on a DBI-SALA Tripod. The SRD-R is mounted on a leg of the Tripod, and the Lifeline is routed through a Pulley System on

the Head of the Tripod:

1. Secure the Quick Mount Bracket on the leg of the Tripod: Assemble the Quick Mount Bracket around the Upper

Tube of the Tripod Leg. Position the Quick Mount Bracket at least 12 in (30 cm) above the Locking Pin on the Tripod

Leg and then tighten the mounting bolts to 15 ft-lbs (20 Nm). Do not overtighten the bolts.

;Never mount the Quick Mount Bracket on the Lower (Telescoping) Tube of the Tripod Leg.

2. Secure the SRD Mounting Bracket on the Quick Mount Bracket: Position the notches in the SRD Mounting

Bracket over the Rod Ends protruding from the Quick Mount Bracket and then pivot the SRD toward the Tripod Leg

until the holes in the SRD Mounting Bracket align with the holes in the Quick Mount Bracket. Insert the Mounting Pin

through the holes in the SRD Mounting Bracket and Quick Mount Bracket.

3. Route the SRD Lifeline over the Tripod Head Mount Pulleys: Remove the two Retainer Pins from the Head

Mount. Position the SRD Lifeline cable in the grooves in the two Head Mount Pulleys. Reinsert the Retainer Pins

through the Head Mount.

4.0 Operation

;First time or infrequent users should review the “Safety Information” at the beginning of this manual prior to use of

the Self-Retracting Device (SRD).

;When using this equipment and connecting subsystem(s), the employer must have a written rescue plan and the

means at hand to implement and communicate that plan to users, authorized persons, and rescuers.

4.1 BEFORE EACH USE: Before each use of this fall protection equipment carefully inspect it to assure it is in good working

condition. Check for worn or damaged parts. Ensure all bolts are present and secure. Check that the lifeline is retracting

properly by pulling out the line and allowing it to slowly retract. If there is any hesitation in retraction, the unit should be

marked as “UNUSABLE” and returned to an authorized service center for service. Inspect the lifeline for cuts, frays, burns,

crushing, and corrosion. Check locking action by pulling sharply on the line. See Section 5 for inspection details. Do not use

if inspection reveals an unsafe condition.

4.2 AFTER A FALL: Any equipment which has been subjected to the forces of arresting a fall or exhibits damage consistent

with the effect of fall arrest forces must be removed from service immediately, marked as “UNUSABLE”, and inspected and

serviced as instructed in Sections 5 and 6.

4.3 MAKING CONNECTIONS: When using a hook to make a connection, ensure roll-out cannot occur (see Figure 5). Do not

use hooks or connectors that will not completely close over the attachment object. Do not use non-locking snap hooks.

The mounting surface should meet the anchorage strength requirements stated in Section 1.4. Follow the manufacturer’s

instructions supplied with each system component.

4.4 OPERATION: Inspect the SRD as described in Section 5.0. Connect the SRD to a suitable anchorage or anchorage

connector as previously described. Connect the Self-Locking Snap Hook on the end of the lifeline to the Dorsal D-Ring

on the Full Body Harness (see Figure 10). Ensure connections are compatible in size, shape, and strength. Ensure hook is

fully closed and locked. Once attached, the worker is free to move about within the recommended working area at normal

speeds. When working with an SRD, always allow the lifeline to recoil back into the device under control. A tag line may

be required to extend or retract the lifeline during connection and disconnection operations. A tag line can be used to

prevent uncontrolled retraction of the lifeline into the SRD. Depending on the work site environment and conditions, it

may be necessary to restrain the free end of the tag line to prevent interference and entanglement with equipment or

machinery.

4.5 RETRIEVAL OPERATION: Figure 10 illustrates operation of the Integral Rescue Hand Crank on the Ultra-Lok Retrieval

SRD-R. Do not attempt to operate Retrieval with the lifeline fully retracted. To activate Retrieval mode and use the Rescue

Hand Crank:

1. Loosen the Locking Thumb Screw to release the Crank Arm.

2. Rotate the Retrieval Handle up from the SRD Body 90°.

3. Pull and hold the Shift Knob in the unlocked position.

4. Push the Crank Arm in and release the Shift Knob to engage. If needed, rotate the Crank Arm clockwise to help

engage the gear.

5. Raise and lower the Lifeline as illustrated in Figure 10:

A. To Raise: Rotate the Crank Arm clockwise.

B. To Lower: Rotate the Crank Arm counterclockwise. After fall arrest; crank the Crank Arm clockwise slightly first

to release the Fall Arrest Brake, then crank the Crank Arm counterclockwise.

;The Integral Rescue Hand Crank on 3-Way Emergency Retrieval SRD-R models is for rescue purposes only and

should not be used for work positioning or material lifting/lowering.

;DBI-SALA SRD-Rs do not incorporate an Overload Clutch to limit the force exerted on the drive components and

attached person. Avoid line slack while in Retrieval mode. Also, monitor the individual during retrieval to ensure they

are not subjected to excessive force from continued lifting after entanglement on an obstruction.

;A minimum load of 75 lbs (33.9 kg) is required to lower or pay out the Lifeline. A force of 30 lbs (0.13 kN) is

required to operate the Retrieval system when loaded to capacity.

;Stop cranking when the Lifeline is fully extended or retracted. Continued cranking can damage components.

4.6 RETRIEVAL DISENGAGEMENT: To disengage Retrieval mode:

;When Retrieval mode is disengaged, any extended Lifeline will retract into the SRD. To avoid possible injury, retract

the Lifeline prior to disengagement or hold onto the Lifeline.

1. Remove any load from the Lifeline.

2. Pull and hold the Shift Knob in the unlocked position.

3. Pull the Crank Arm out to disengage and then release the Shift Knob.

4. Pull out and rotate the Retrieval Handle down toward the SRD Body to stowed position.

5.0 Inspection

5.1 RFID TAG: The Self-Retracting Device includes a Radio Frequency Identication (RFID) tag (see Figure 11). The RFID

tag (A) can be used in conjunction with the handheld reading device and web based portal to simplify inspection and

inventory control and provide records for your fall protection equipment. For details, contact a 3M Customer Service

representative (see back cover). Follow the instructions provided with your handheld reader, or on the web portal, to

transfer your data to your web log.

5.2 INSPECTION FREQUENCY: The Ultra-Lok Self-Retracting Device must be inspected at the intervals dened in Section 2

(Inspection Frequency). Inspection procedures are described in the “Inspection & Maintenance Log” (Table 3).

5.3 UNSAFE OR DEFECTIVE CONDITIONS: If inspection reveals an unsafe, defective condition, remove the

Self-Retracting Device from service immediately, mark as “UNUSABLE”, and perform a Competent Person inspection to

determine service options.

5.4 PRODUCT LIFE: The functional life of DBI-SALA Self-Retracting Devices is determined by work conditions and

maintenance. As long as the product passes inspection criteria, it may remain in service.

6.0 Maintenance, Service, and Storage

6.1 CLEANING: Cleaning procedures for the Self-Retracting Device are as follows:

• Periodically clean the exterior of the SRD using water and a mild soap solution. Position the SRD so excess water can

drain out. Clean labels as required.

• Clean lifeline with water and mild soap solution. Rinse and thoroughly air dry. Do not force dry with heat. An

excessive buildup of dirt, paint, etc., may prevent the lifeline from fully retracting back into the housing causing a

potential free fall hazard. Replace lifeline if excessive buildup is present.

6.2 SERVICE: Additional service, determined from the Competent Person inspection, must be completed by an authorized

service center. Do not attempt to disassemble the SRD or lubricate any parts.

6.3 STORAGE AND TRANSPORT: Store and transport the SRD in a cool, dry, clean environment out of direct sunlight. Avoid

areas where chemical vapors may exist. Thoroughly inspect the SRD after any period of extended storage.

7.0 Labels

SRD

(Figure 12)

Inspect for loose bolts and bent or damaged parts.

Inspect Housing (A) for distortion, cracks, or other damage.

Inspect the Swivel Eye (B) for distortion, cracks, or other damage. The Swivel Eye should be attached

securely to the SRD, but should pivot freely.

The Lifeline (C) should pull out and retract fully without hesitation or creating a slack line condition.

Ensure device locks up when lifeline is jerked sharply. Lockup should be positive with no slipping.

NOTE: SRDs with RSQ should be in Fall Arrest Mode for this test.

The labels must be present and fully legible (see “Labels”).

Look for signs of corrosion on the entire unit.

Swivel Snap Hook &

Impact Indicator

(Figure 13)

Inspect the Swivel Snap Hook for signs of damage, corrosion, and working condition. Swivel should

rotate freely. Inspect the Impact Indicator. If the Red Band is displayed (Indicated Mode), impact

loading has occurred and the SRD must be removed from service and inspected. Do not attempt to

reset the Impact Indicator. Return the SRD to an authorized service center for resetting. NOTE: The

Swivel will not turn freely when the Impact Indicator is in Indicated Mode.

Wire Rope Lifeline

(Figure 14)

Inspect wire rope for cuts, kinks (A), broken wires (B), bird-caging (C), welding splatter (D),

corrosion, chemical contact areas, or severely abraded areas. Slide the cable bumper up and inspect

ferrules for cracks or damage and inspect the wire rope for corrosion and broken wires. Replace the

wire rope assembly if there are six or more randomly distributed broken wires in one lay, or three or

more broken wires in one strand in one lay. A “lay” of wire rope is the length of wire rope it takes for

a strand (the larger groups of wires) to complete one revolution or twist along the rope. Replace the

wire rope assembly if there are any broken wires within 1 inch (25 mm) of the ferrules.

Reserve Lifeline

(Figure 15)

Inspect the Reserve Lifeline payout. If a fall has been arrested with most of the lifeline out, the

Reserve Lifeline may have been deployed. Pull the lifeline out of the SRD until it stops. If the Button

Stop (A) pulls out and is visible, the Reserve Lifeline is spent and the lifeline should be replaced.

Retrieval Integral

Rescue Hand Crank

(Figure 16)

Inspect the Crank Arm (A) for distortion or other damage. Ensure that the Retrieval Handle (B) can be

folded out and secured in the cranking position.

Ensure the Retrieval Shift Knob (C) can be pulled out to the unlocked position and then released,

locking the Crank Arm in both the engaged and disengaged positions.

Test the retrieval feature for proper operation by raising and lowering a test weight of at least 75 lbs

(34 kg). When the Retrieval Handle is released, the weight should not move and the Retrieval Handle

should remain in position (no movement). A ‘clicking’ sound should be audible when raising the load.
