PRODUCT OVERVIEW

Figure 1 illustrates the 3M™ Protecta® Self-Retracting Device (SRD). Protecta SRDs are drum-wound lifelines with an inline energy absorber that retract into thermoplastic housings. Protecta SRDs are available in single- and twin-SRD models. Twin-SRD models may be used to maintain 100-percent tie-off when transferring between anchorage points.
The following SRD types are covered by this instruction:

• Self-Retracting Device (Figures 1.1, 1.2; 2.1, 2.2): Self-Retracting Devices (SRDs) are suitable for applications where the lifeline remains generally vertical during use. This type may be used for Fall Arrest or Restraint applications.

Figure 2 identifies key components of the available SRD models. In a standard SRD, the Lifeline (A) extends and retracts from within the Housing (B). The Top Connector (D) secures the SRD to its mounting point and is connected to the SRD by means of the Swivel Eye (E). The Bottom Connector (C) is secured at the end of the Lifeline. Depending on system configuration, the Bottom Connector will attach to either the designated attachment element of the user’s full body harness or to the system’s anchorage point. Energy Absorbers (F) dissipate kinetic energy and limit deceleration forces during fall arrest.
Twin-SRD models include a single Top Connector (D) to be shared between the two SRDs. These connectors are designed to interface with harnesses so that the Twin-SRD model may be worn on the user’s back.
Each product model has its own particular size and its own combination of components as listed in Figure 1. See Table 1 for more information on Component Speci

PRODUCT APPLICATION

1.1 PURPOSE: 3M Self-Retracting Devices (SRDs) are designed for use as a connecting subsystem in a Fall Protection system. Once anchored, the lifeline extends and retracts automatically as the worker moves. If a fall occurs, a sensing mechanism activates the device and arrests the fall. For more information on system applications, refer to the “Product Overview” and Table

1.2 SUPERVISION: Use of this equipment must be supervised by a Competent Person.
1.3 STANDARDS: Your product conforms to the national or regional standards identified 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 certification or conformance requirements, refer to the applicable standards and regulations listed for your product (e.g. the ANSI/ASSP Z359 Fall Protection codes).
1.4 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.
1.5 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 proficiency. 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.

SYSTEM REQUIREMENTS

2.1 ANCHORAGE: Anchorage requirements vary with the Fall Protection application. The mounting structure on which the equipment is placed must meet the Anchorage specifications defined in Table 1.
2.2 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.
2.3 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 clarification.
2.4 LIFELINE HAZARDS: Ensure the lifeline is kept free from all hazards including, but not limited to: entanglement with users, other workers, moving machinery, other surrounding objects, or impact from overhead objects that could fall onto the lifeline or users.
2.5 FALL PATH AND SRD LOCKING SPEED: Do not use in applications that have an obstructed fall path. A clear path is required to lock the SRD. Working on slowly shifting materials (e.g. sand or grain), or within limited spaces, may not allow the worker to reach sufficient speed to lock the SRD.
2.6 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.
2.7 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 specified in each instruction manual. Ensure connectors are compatible with the system components to which they are connected. Do not use equipment that is noncompatible. 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).

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 connectors:
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 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 confirmation, would seem to be fully engaged.
D. To each other.
E. Directly to harness webbing, lanyard leg material, or tie-back material unless such a connection is explicitly allowed for by the manufacturer instructions.
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.

INSTALLATION

3.1 OVERVIEW: Installing this product requires effective planning and knowledge of fall clearance requirements. In the event of a fall, there must be enough fall clearance present to safely arrest the user.
3.2 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 specified in these instructions.
A. 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.

Only SRD-LEs may be used for applications with unprotected sharp edges or abrasive surfaces.

3.3 FALL CLEARANCE: It is critical that the user is aware of fall clearance and its requirements before using this product.
A. DEFINITION: Fall clearance is the measure of distance between a user and the next obstruction below them. Before use of this product, the user should determine how much fall clearance is required to prevent them from striking an obstruction should they fall.
A user’s Required Fall Clearance (FC) is the sum of Free Fall (FF), Deceleration Distance (DD), Harness Stretch (HS), and a Safety Factor (SF). See Figure 5.1 for reference.

• Free Fall (FF) is the distance the user travels before activation of the deceleration device.
• Deceleration Distance (DD) is the distance the user falls measured from activation of the deceleration device until stopping.
• Harness Stretch (HS) is the amount of slack extending from the user’s harness when the user is suspended by their harness attachment element.
• Safety Factor (SF) is a set amount of distance added to fall clearance to ensure user safety.
  There may be additional factors affecting Required Fall Clearance within your Fall Arrest system, such as D-ring extension length and anchorage deflection. For coverage of these factors, and others not outlined above, refer to the manufacturer instructions for each component of your Fall Arrest system. Additional factors, when provided, should be added to the fall clearance values in this instruction.

B. MINIMIZING REQUIREMENTS: The user should always position their Fall Arrest system to minimize fall potential and potential fall distance. To keep fall clearance requirements to a minimum, it is recommended that the user work as directly below their anchorage point as possible.

• ANCHORAGE HEIGHT: The Required Fall Clearance (FC) for a user increases as Anchorage Height (A) decreases. The user experiences a greater amount of free fall when connected to an anchorage point below them, since the user will have to travel that much farther should they fall. See Figure 5.2 for reference.
• SWING FALLS: The Required Fall Clearance (FC) for a user increases as User Work Radius (W) increases. Swing falls occur when the anchorage point is not directly above the user when a fall occurs. See Figure 5.3 for reference.

Figure 5 – Fall Clearance Requirements

FALL CLEARANCE CHARTS

Required Fall Clearance has been provided within the charts below. To determine Required Fall Clearance:

1. Locate your first connector (1). Measure the Anchorage Height (A) and Maximum Work Radius (W) of your connector, relative to the height of your D-ring. Place your first connector in the chart where these intersect.
2. Locate your second connector (2). Use the same method from Step 1 to place your second connector in the chart.
3. Find your Required Fall Clearance (FC). Locate the chart “wing” each connector falls into, then locate the corresponding fall clearance in the table to the right. The fall clearance table is divided into columns, depending on capacity. Select the value within the column matching your total user capacity (including clothing, tools, etc.).

If your connectors are in different wings, you must use the greater fall clearance requirement between them.

A Safety Factor of 1.0 m (3.28 ft.) and a user height of 1.8 m (6 ft. 0 in.) were used for all values listed. Kneeling or crouching will reduce the position of the user above the platform and will require an additional 1.0 m (3 ft. 3 in.) of fall clearance.
Required Fall Clearance is calculated with the assumption that each leg of the SRD is extended a minimal distance behind the user, from wherever they may be positioned in the chart. The assumption of minimum setback distance ensures the user has enough fall clearance regardless of their actual setback distance.
Never secure your connector within chart areas marked by cross hatching or crossed-out table cells.

3.5 CONNECTING TO ANCHORAGE : Figure 6 illustrates typical SRD anchorage connections. The Anchorage (A) should be directly overhead to minimize free fall and swing fall hazards (see Section 3.3.B). Select an anchorage capable of sustaining the static loads defined in Table 1. Depending on system and product configuration, the SRD may be mounted on the anchorage point or on the user’s full body harness.
Large-throat snap hooks must never be secured to D-rings or other connecting elements unless they have a gate strength of 16 kN (3,600 lbf) or greater.
A. ANCHORAGE MOUNTING: Single-SRD models may be mounted on anchorage points as long as they are installed properly and have the right connectors for securing on an anchorage point. The top connector must be a carabiner, snap hook, or rebar hook. To secure an SRD overhead, first secure the Top Connector (B) to the anchorage point.
Then, secure the Bottom Connector (C) directly to the dorsal D-ring (D) of your harness.
B. HARNESS MOUNTING: Harness-mounted SRDs are secured to the full body harness directly by their Harness Interface (E). The user then secures to anchorage connection points using their Bottom Connectors (C). Twin-SRD models enable the user to maintain 100-percent tie-off when transferring between anchorage points.
Always ensure that you are appropriately securing and anchoring your SRD. Some SRD models may have anchorage height restrictions. See the fall clearance charts for more information on these restrictions, if present.

3.6 INSTALLING A HARNESS-MOUNTED SELF-RETRACTING DEVICE: Single- and Twin-SRD models with harness web interfaces as their top connector may be installed directly onto the user’s full body harness. This format enables easier transportation of the SRD and ensures that the SRD is within reach when moving between anchorage points. The methods for mounting an SRD on a harness vary with SRD model and the interface provided.
Harness interfaces may also be used in coordination with specific features of full body harnesses to secure the Single- or Twin-SRD to the harness. Examples include the pSRD Link and the molded X100 SRD Interface Loop present on some 3M harness models. The following instructions provide a general method for how each harness interface should be used. See the manufacturer instructions of your full body harness for more information on specific features for interfacing with SRDs.

A. CARABINER INTERFACE: See Figure 7 for reference. These instructions apply to Carabiner 2000192 when used with specific ExoFit Full Body Harness models.

1. Loosen the harness webbing. Pull out on the Web Straps (A) where they pass through the bottom of the Dorsal D-ring (B) until there is enough space to slide the carabiner through.
2. Open the carabiner. With the carabiner oriented as illustrated, push the Locking Sleeve (C) to the right, then turn clockwise to unlock the Gate (D). Push the Gate (D) down to open.
3. Thread the first SRD onto the carabiner. Insert the Nose (E) of the carabiner through the Swivel Eye (F) of the SRD, then loop the SRD through to the Gate End (G) of the carabiner.
4. Position the carabiner around the web straps. Insert the Nose (E) of the carabiner behind the loosened Web Straps (A), between the straps and the back pad of the harness. Rotate the carabiner until it surrounds the loosened straps.
5. Thread the second SRD onto the carabiner. Slide the Swivel Eye (F) of the SRD over the Nose (E) of the carabiner. Position the SRD along the nose end of the carabiner.
6. Close the carabiner. Release the gate and allow the carabiner to rotate back to its locked position. Once closed, pull the the Web Straps back through the harness to secure the carabiner.

USE

4.1 BEFORE EACH USE: Verify that your work area and Fall Protection system meet all criteria defined in these instructions.
Verify that a formal Rescue Plan is in place. Inspect the product per the ‘User’ inspection points defined in the “Inspection and Maintenance Log”. If inspection reveals an unsafe or defective condition, or if there is any doubt about its condition for safe use, remove the product from service immediately. Clearly tag the product “DO NOT USE”. See Section 5 for more information.
4.2 AFTER A FALL: If this equipment is subjected to fall arrest or impact force, remove it from service immediately. Clearly tag it “DO NOT USE”. See Section 5 for more information.
4.3 OPERATION: Before using an SRD, the worker will need to secure the SRD to an anchorage connection point and an attachment element on their full body harness. Once secured, the worker may move within the established safe working area at normal speeds. During use, always allow the SRD lifeline to recoil back into the device under control.
4.4 TAGLINES: Depending on the worksite and system configuration, the user may not always be able to reach the SRD at its anchor point. In these situations, a tagline may be necessary. A tagline is a long piece of cord that loops through the bottom connector of the SRD before looping back in on itself. When connected in this way, the user can raise or lower the bottom connector of the SRD to their location by pulling on the tagline.

Ensure the free end of the tagline does not become entangled with other workers, equipment, or machinery. If necessary, restrain the free end of the tagline.

4.5 LANYARD PARKING ATTACHMENT: When not in use, the free end of a lanyard or harness-mounted Self-Retracting Device (SRD) must be secured to the lanyard parking attachment on the user’s harness (A) or be held securely within the user’s hand (B). See Figure 8 for reference.
The free end of a connecting subsystem must always be properly secured. Never allow free ends to hang freely (C) and never secure free ends to an unused attachment element on the user’s harness (D). Both of these situations could create
a trip hazard or cause the user to become entangled.
Never use lanyard parking attachments as attachment elements for Fall Protection applications.

4.6 USING TWIN-SRD MODELS: Twin-SRD models, when mounted on a harness, may be used for Fall Arrest or Restraint applications. Additionally, Twin-SRDs may be used for climbing applications, such as ascending or descending a rebar structure. Twin-SRDs enable the user to maintain 100-percent tie-off when moving between anchorage points. As long as one SRD is secured to an anchorage point, the user may disconnect the other SRD and move it to a different anchorage point. By disconnecting and reconnecting each SRD in turn, the user may travel along a surface and still maintain tie-off during movement.
The user must always consider the following before using a Twin-SRD:

• When in the vicinity of a fall hazard, the user must always have at least one SRD connected to an anchorage point.
  Never connect both SRDs to the same anchorage point. See Figure 9.1 for reference.

• Never permanently secure both SRDs to anchorage points simultaneously. Twin connections should only be made for the purpose of maintaining 100-percent tie-off.

• Each individual anchorage point must be strong enough to meet the anchorage requirements listed in Table 1.

• The individual SRDs must only be used to secure to anchorage points. Never secure two workers via the same system. See Figure 9.2 for reference.

• The lifeline of each SRD must always be kept free from obstructions and entanglement. Do not pass either SRD under arms or between legs during use.

4.7 USE WITH HORIZONTAL SYSTEMS: The SRDs covered in this instruction are compatible for use with horizontal systems, such as Horizontal Lifeline (HLL) systems and horizontal rail systems. See the manufacturer instructions of your horizontal system for more information on its compatibility with SRDs. SRDs may be used with a horizontal system only if both products allow for such use.

Required Fall Clearance values presented in these instructions are based on use with a rigid, stationary anchorage point. These values do not apply when the product is used with a Horizontal Lifeline (HLL) system. See the manufacturer instructions of your HLL system for fall clearance charts specific to that system, or for additional factors that must be accounted for before using the charts in these instructions.
