Description
The Fall Tech(R) Dura Tech TM Mini SRL-P is a personal self-retracting device for those working at height and may be subject to fall hazards. This product is not suitable for applications with leading edge exposures where the lifeline of this device may come in contact with an edge during a fall event. This product is a personal SRL and may be used with the SRL housing side connected to the anchor or connected to the full body harness. Contact Fall Tech for more information or product selection questions.
This manual includes one Appendix containing figures and tables specific to the Dura Tech Mini SRL-P discussed in this manual. The SRL discussed in this manual may be attached to an overhead anchorage, i.e., from directly over the user’s head, or to an anchorage at a maxi-mum of 5’ below the user’s FBH dorsal D-ring. Below D-ring tie-off is outside the scope of ANSI Z359 and is only allowed when no edge hazards are present. At no point during a fall shall the lifeline be loaded over any edge. As shown in Figure 1 below, the Dura Tech Mini has a nylon housing that contains a Dyneme (R) synthetic lifeline wound onto a spring tensioned drum. The Dura Tech Mini lifeline is equipped with an energy absorber and a leg-end connector. When the user is attached, the lifeline extends and retracts with the user movement, automatically maintaining taut lifeline. If a fall occurs, a centrifugal pawl system engages, stopping the lifeline payout. Then, the inline Energy Absorber (EA) will deploy, gradually slowing and arresting the fall. See Table 1A in Appendix A for product, material, and performance specifications.

American National Standards Institute (ANSI) and Occupational Safety and Health Administration (OSHA): The SRD discussed in this manual meets the standards of ANSI Z359.14-2021, ANSI A10.32-2012, and Occupational Safety and Health Administration (OSHA) regulations 1926.502 and 1910.140. ANSI requires SRDs be classified according to the type of usage the user would be exposed to, and are tested either as Class 1 or Class 2. Dynamic performance means that the SRD is installed in a testing drop tower. A test weight is attached to the SRD and then dropped. Test results are recorded.
Parameters recorded are:

• Arrest Distance (AD)
• Average Arrest Force (AAF)
• Maximum Arrest Force (MAF)

The Arrest Distance is the total vertical distance required to arrest a fall. The Arrest Distance includes the deceleration distance and the activation distance. The Average Arrest Force is the average of the forces applied to the body and the anchorage by the fall protection system. The Maximum Arrest Force is the maximum amount of force that may be applied to the body and the anchorage by the fall protection system. In addition to the above tests conducted in ambient conditions, the units must be retested for average and peak forces under certain environmental conditions, where the units are cooled, then tested, heated, then tested, or saturated in water and tested again. Separate units may be used for each test. All test results are recorded. This test data is then used to establish the basis for fall clearance guidelines published in the user instruction manual.

Class 1 and 2
Class 1 devices shall be used only on overhead anchorages and shall be subjected to a maximum free fall of 2 feet (0.6 m) or less. Class 2 devices are intended for applications where an overhead anchorage may not be available or feasible and be subjected to a free fall of no more than 6 feet (1.8 m) over an edge. To be declared a Class 1 and Class 2 device, ANSI requires an SRD to have an overhead Arrest Distance of less than 42” (1.1 m), an Average Arrest Force of less than 1,350 lbs (6 kN) [1,575 lbs (7 kN) conditioned] and a Maximum Arresting Force of 1,800 lbs (8 kn), for both ambient and conditioned testing. When dynamically tested in accordance with requirements of ANSI Z359.14-2021, Fall Tech Class 1 and Class 2 Self-Retracting Devices have an AAF of 1,350 lbs (6 KN) or less and an AD of less than 42” (1.1 m).

Please see Section 5 of this user instruction manual for how to calculate your Minimum Required Fall Clearance (MRFC) Please see Section 5.2 of this user instruction manual for how to calculate your Minimum Required Fall Clearance (MRFC) using the affixed labels. Classification information found on product labels is based on test results. Table 1B in Appendix A provides test performance results for the SRD discussed in this manual. NOTE: Arrest distance is one of several parts of the Minimum Required Fall Clearance (MRFC). MRFC is discussed in detail in Section 5 . OSHA requires an SRD limit the free fall to 2 feet (0.9 m) or less. If the maximum free fall distance must be exceeded, the employer must document, based on test data, that the maximum arresting force will not be exceeded, and the personal fall arrest system will function properly. Contact Fall Tech for more information on this testing.

Application

Purpose
The DuraTech Mini SRL-P is designed to be used as a component in a Personal Fall Arrest System (PFAS), to provide a combination of worker mobility and fall protection as required for inspection work, general construction, maintenance work, oil production, confined space work, etc.

Personal Fall Arrest System
A PFAS is an assembly of components and subsystems used to arrest a person during a fall event. A PFAS typically consists of an anchorage, a deceleration device such as a Energy Absorbing Lanyard (EAL), a Self-Retracting Device (SRD), or a Fall Arrestor Connecting Subsystem (FACSS), and a properly fitted Full Body Harness (FBH). The SRD discussed in this manual may be used in non- overhead anchorage situations. Maximum permissible free fall in a typical PFAS is 6’ (1.8 m). Other applications may be below the D-ring, but no edge exposures are allowed with this product.

Horizontal Lifeline (HLL) and Rail Systems
The SRL may be attached to rigid and flexible anchors provided that all HLL or rail system applications, installation, and uses are under the supervision of a qualified person.

Rescue
Ensure a written rescue plan, method, and system is in place and readily available for rapid response. Rescues may require specialized equipment or measures. Rescue operations are beyond the scope of this manual. See ANSI Z359.4.

Application Limits
Take action to avoid moving machinery, abrasive surfaces, and thermal, electrical, including the arc from welding applications, and chemical hazards as contact may damage the SRL, which may result in serious injury or death. The SRL is not designed for use in restraint, personnel riding, suspension, or work positioning. Rescue applications are beyond the scope of this manual. Do not use the SRL for these applications except as a back-up PFAS.

System Requirements

Capacity
The Dura Tech Mini SRL-P is designed for use by a single user with a combined weight of user, tools, clothing, etc., of 130 to 310 lbs. (59 to 141 kg) to comply with ANSI and OSHA.

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 FallTech if you have any questions about compatibility. Connectors must be compatible with the anchorage or other system components. Do not use equipment that is not compatible, see Figure 2. Non-compatible connectors may unintentionally disengage. Connectors must be compatible in size, shape, and strength. Self-closing, self-locking connectors are required by ANSI and OSHA.

Figure 2 – Non-Compatible Connections

• A. Never connect two active components (snap hooks or carabiners) to each other.
• B .Never connect two active components (snap hooks or carabiners) to a single D-ring at the same time.
• C .Never connect in a way that would produce a condition of loading on the gate.
• D .Never attach to an object in a manner whereby the gate (of the snap hook or carabiner) would be prevented from fully closing and locking. Always guard against false connections by visually inspecting for closure and lock.
• E .Never attach explicitly to a constituent subcomponent (webbing, cable or rope) unless specifically provided for by the manufacturer’s instructions for both subcomponents (snap hook or carabiner and webbing, cable, or rope).
• F .Never attach in a manner where an element of the connector (gate or release lever) may become caught on the anchor thereby producing additional risk of false engagement.
• G .Never attach a spreader snap hook to two side/positioning D-rings in a manner whereby the D-rings will engage the gates; the gates on a spreader must always be facing away from the D-rings during work positioning.

Compatibility Of Components
Equipment is designed for use with approved components and subsystems only. Substitutions or replacements made with non-approved components or subsystems may jeopardize compatibility of equipment and may affect the safety and reliability of the complete system.

Making Connections
Only use self-locking connectors with this equipment. Only use connectors that are suitable to each application. Ensure all connections are compatible in size, shape, and strength. Do not use equipment that is not compatible. Visually ensure all connectors are fully closed and locked. Connectors are designed to be used only as specified in each product’s user instructions.

Personal Fall Arrest System
A PFAS is an assembly of components and subsystems used to arrest a person during a fall event. A PFAS is typically composed of an anchorage and a FBH, with an energy absorbing connecting device, i.e., an SAL, an SRL, or a Fall Arrester Connecting Subsystem (FACSS), connected to the dorsal D-ring of the FBH. PFAS components used in conjunction with this SRL should comply with ANSI Z359 requirements and applicable OSHA regulations.

Average Arrest Force and Arrest Distance
Table 1B in Appendix A provide test data on typical performance attributes of the three principal parameters: Arrest Distance, Average Arrest Force, and Maximum Arrest Force, listed by model number and class. Testing is conducted under various environmental conditions, at ambient temperature, hot, cold, and wet conditions. In manufacturer’s tests, worst case performance attributes of the SRL, connected 5′ below dorsal D-ring in non-Leading Edge applications are:

130 to 310 lbs. (59 to 141 kg) user  5′ Below D-ring

The competent person may find this data useful with planning anchorage location and calculating fall arrest loads and distances from the walking/working level to the nearest obstruction or lower level. See Section 5.
NOTE
Arrest distance is one part of the Minimum Required Fall Clearance (MRFC). The MRFC is determined by consideration of multiple factors in fall protection. Attachment below the level of the FBH D-ring will require additional fall clearance. MRFC is discussed in detail in Section 5.

Personal Fall Arrest System Anchorage Strength
An anchorage selected for PFAS application must have the strength to sustain a static load applied in the direction permitted by the PFAS of at least:

• Two times the maximum arrest force permitted when certification exists, or
• 5,000 lbs. (22.2 kn) in the absence of certification.

Select an anchorage location carefully. Consider structural strength, obstructions in the fall path, and swing fall hazards. In certain situations, the qualified person can determine that a given structure is able to withstand the applied MAF of the PFAS with a safety factor of at least two, as required by OSHA.

Figure 5: Attaching 6’ Mini Twin-leg SRL to FBH

1. Open the Alignment
   Clip from the reverse side by pushing on the top ears to release and (B) allow clip to rotate downward; next, (C) rotate to one side one SRD unit and the clip then open the triple-lock gate on the Carabiner and remove the other SRD unit. (D) Allow gate to close.
   

2. Prepare FBH and Preliminary Attachment
   Lift the Dorsal D-ring to the up-pointing position then loosen the intersection of the two web straps that pass through the one SRD unit still connected to the Carabiner, reopen the gate and insert the nose of the Carabiner into the two intersecting slacked loops; (G) allow the gate to close while the Alignment Clip remains positioned on the gate only.
   

3. Reinstating 2nd SRD Unit
   (H) Now rotate the Carabiner and Alignment Clip 1/4 turn to the horizontal position; while keeping slack in the web loops, the gate and clip will end up positioned below the loops. (I) Keeping the Carabiner horizontal, rotate the SRD unit away from the gate and slide the Alignment Clip off and away from the gate as well. (J) Open the Carabiner gate and insert the nose through the swivel eye of the second SRD unit then allow the gate to close to capture the second SRD. (K) Next, reposition the Alignment Clip back onto the gate.

4. Closing and Securing
   With the Alignment Clip on the gate, rotate the clip upward; then tightly pinch the two web straps together and insert between the ears of the clip and snap the ears to the body of the Carabiner. (M) Lastly, remove the slacked loops from the intersecting web straps by pulling up through the D-ring slot and the D-ring holder. Check the gate for full closure and the Alignment Clip to be securely snapped to the Carabiner body. Don your FBH and adjust as needed for proper fit.

Attaching to an Anchorage
Examine the work area for possible hazards. Take caution to avoid overhead hazards such as cranes, poles, overhead power cables, and walking/working surface hazards such as power cables, welding leads, air and fluid hoses, including obstruction hazards such as vertical columns and stacks of materials on the lower level. Eliminate hazards where possible. Ensure the anchorage provides the Minimum Required Fall Clearance (MRFC) in the fall path below the walking/working surface to prevent striking the lower level or an obstruction during a fall event. Take action to avoid swing falls, which occur when the anchorage is not directly above the point where the fall occurs. Fall clearance and swing falls are subject to variable conditions. Anchor height, lateral movement, and setback distance all affect anchor location with regard to fall clearance and swing falls. The SRL may be attached to an overhead anchor, i.e., above the user’s FBH dorsal D-ring, or a non-overhead anchor, i.e., below the user’s FBH dorsal D-ring. A non-overhead anchor may be a maximum of 5’ (1.5 m) below the user’s FBH dorsal D-ring. Non-overhead anchor locations result in greater possibility of edge hazards. At no point during a fall shall the lifeline be loaded over any edge. Use of a below D-ring anchorages should be as a last resort, when no other anchor option exists. When anchored below the FBH back D-ring, fall events will result in greater fall clearances.

Using the Dura Tech Mini SRL-P
Before each use, inspect the Dura Tech Mini in accordance with Section 7. Remove the device from service if the inspection shows damage or any malfunction.
Don the FBH and/or attach the SRL in accordance with the harness manufacturer’s instructions. Follow the instructions contained in this manual and on the labels. Failure to follow instructions may result in serious injury or death. Connect the leg-end connector to an approved anchorage point or to the full body harness depending on orientation. Ensure the connector closes and locks. In a Twin-leg configuration attach the unused leg end connector to the FBH’s lanyard keeper. Ensure all connections are compatible. Normal operation will allow the working length of the lifeline to extend and retract as the worker moves about. When using a Twin-leg configuration, it is possible to move laterally between anchor points with 100% tie-off as shown in Figure 6.

Figure 6 – Twin-Leg SRLs for Lateral Movement

Avoid sudden or quick movements during the normal work operation, as this may cause the SRL pawl system to engage and possibly cause loss of balance, which may cause injury or death. If a fall occurs, the pawl system will engage and lock the lifeline. The EA will deploy to arrest the fall and limit arrest forces on the user.

Locking Mechanism
The SRD utilizes an acceleration based locking mechanism. The locking function requires a certain payout rate during a fall event to function correctly. Certain situations, confined or cramped spaces, shifting footing such as sand, gravel, grain, or a sloped surface may not allow the lifeline to reach sufficient speed to activate the lock mechanism. A clear path is required to assure positive locking of the SRD. Ensure the lock is functioning properly. Pull the lifeline out a short distance and give it a sharp tug. The lifeline must lock. If it fails to lock, remove it from service immediately. Ensure the work zone remains within stated parameters.

Visual Indicator
The primary fall arrest impact indicator is the energy absorber in the lifeline between the housing and the leg-end connector. Torn stitching, deployment, expansion, or lengthening of the white internal energy absorber webbing is an indication that a fall event has occurred and the unit must be removed from service. Remove from service any unit that fails inspection, including inspection of the fall arrest impact indicator. If you have any questions, contact FallTech.

After A Fall
A fall event over an edge may require special rescue equipment and measures. Ensure a written rescue plan, method and system is in place and readily available to all users for rapid response. Ensure all users are trained in rescue procedures. If a fall event occurs, remove it from service, and store it separately. Remove from service any unit that has been subjected to fall arrest forces or that exhibits damage consistent with such forces. For questions, contact FallTech.

Using the SRD
Do not use the SRD if inspection shows damage or any malfunction. Don the FBH in accordance with the FBH manufacturer’s instructions. Follow the instructions contained in this manual and on the labels. Failure to follow instructions may result in serious injury or death. Connect the SRL-FBH Connector to the dorsal D-ring on the FBH. Ensure the connector closes and locks. Attach the leg-end carabiner to the chosen anchorage and ensure the leg-end connector closes and locks. Ensure all connections are compatible. Normal operation will allow the working length of the lifeline to extend and retract as the worker moves about. A certain amount of tension must remain on the web at all times to ensure proper operation of the internal brake. Do not allow the lifeline to become slack. If the lifeline becomes slack, remove the SRD from service for inspection. See Section 7. Avoid sudden or quick movements during the normal work operation, as this may cause the SRD brake to engage and possibly cause loss of balance and injury or death. If a fall occurs, the brake will engage and lock the lifeline. The EA will deploy to arrest the fall and limit arrest forces on the user.

• DO NOT extend the lifeline past the operational limit.
• DO NOT allow one SRD lifeline to become tangled or twisted with another SRD lifeline during use.
• DO NOT allow any lifeline to pass under arms or between legs during use.
• DO NOT clamp, knot, or prevent the lifeline from retracting or being taut.
• DO NOT lengthen the SRD by connecting a lifeline or similar component.
• DO NOT allow the lifeline to remain outside the housing when not in use.

Calculating Minimum Required Fall Clearance

Dura Tech Mini in Overhead, Non-Leading Edge Anchorage Application [130 to 310 lbs. (59 to 141 kg) user] The Mini may be used may be used as a standard SRD in an overhead condition, in which the SRD is installed anywhere in the allowable attachment area, which ranges from directly above the user to level with the FBH D-ring, as shown in Figure 7. The overhead condition minimum required fall clearance (MRFC) is calculated using four metrics, measured from the walking-working surface: SRD Deceleration Distance, D-Ring Shift and Harness Stretch [1 ft (0.3m)], Safety Factor [1.5 ft (0.5m)], and Swing Fall. The diagram in Figure 8 is calculated using the performance data of the SRD and includes all four metrics listed previously to determine the MRFC. Dura Tech Mini with a Non-Overhead, Non-Leading Edge Anchorage Application [130 to 310 lbs. (59 to 141 kg) user] The non-leading edge below D-ring condition minimum required fall clearance (MRFC) is calculated using five metrics, measured from the walking-working surface: SRD Deceleration Distance, D-Ring Shift and Harness Stretch [1 ft (0.3m)], Safety Factor [1.5 ft (0.5m)], Dorsal D-ring Height [5 ft (1.5m)], and Swing Fall. Dorsal D-ring height is added to account for the below D-ring tie-off compared to the overhead condition. The diagram in Figure 8 is calculated using the performance data of the SRD and includes all five metrics listed previously to determine the MRFC. Below D-ring tie-off is outside the scope of ANSI Z359 and is only allowed when no edge hazards are present. At no point during a fall shall the lifeline be loaded over any edge.

Figure 8 – Dura Tech Mini Minimum Required Fall Figure 8 – Dura Tech Mini Minimum Required Fall

1 foot (0.3 m) increments along the X-Axis represents the Horizontal Distance to Anchorage the user is working away from the SRD.
1 foot (0.3 m) increments up the Y-Axis represent the Elevation of the Anchorage.

Example 1
If the user is working 3 feet (0.9 m) away from the SRD, and the SRD is anchored between 1 ft (0.3 m) above the user’s Dorsal D-Ring or up to 2 ft (1.1 m) above the D-Ring. Minimum required fall clearance is 8 feet (2.4 m) including swing fall.

Example 2
If the user needs to work 4 feet (1.2 m) away from the SRD along the edge, and the SRD is anchored at foot level, the minimum required fall clearance is 19 feet (5.6 m) including swing fall.

Maintenance, Service, and Storage

Maintenance
Ensure the SRL is kept free of excess paint, grease, dirt or other contaminants as this may cause the lifeline or retracting mechanism to malfunction. Ensure no debris enters the housing. Clean the exterior of the unit as required with a detergent/water solution. Do not allow water or other corrosion causing elements to enter the housing. After cleaning, pull the lifeline all the way out, allow the unit to air dry, then retract the lifeline into the unit. Clean labels as required.
DO NOT use heat to dry.
DO NOT attempt to disassemble the SRL.

Service
Remove the unit from service if it has been subjected to fall arrest force. Tag the unit as “UNUSABLE” to prevent future use. The SRD is not repairable.
Storage: Store the Dura Tech Mini in a cool, dry, clean environment out of direct sunlight. Position the SRL so excess water can drain out. Avoid exposure to chemical or caustic vapors. Thoroughly inspect the SRL after any period of extended storage.

Definitions

The following are general definitions of fall protection terms as defined by ANSI Z359.0-2012. Anchorage -A secure connecting point or a terminating component of a fall protection system or rescue system capable of safely supporting the impact forces applied by a fall protection system or anchorage subsystem.

Anchorage Connector
A component or subsystem that functions as an interface between the anchorage and a fall protection, work positioning, rope access or rescue system for the purpose of coupling the system to the anchorage.

Arrest Distance
The total vertical distance required to arrest a fall. The arrest distance includes the deceleration distance and activation distance.

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

Available Clearance
The distance from a reference point, such as the working platform, to the nearest obstruction that an authorized person might contact during a fall which, if struck, could cause injury.
Capacity
The maximum weight that a component, system or subsystem is designed to hold.
Certification
The act of attesting in writing that the criteria established by these standards or some other designated standard have been met.
Certified Anchorage
An anchorage for fall arrest, positioning, restraint or rescue systems that a qualified person certifies to be capable of supporting the potential fall forces that could be encountered during a fall.

Clearance
The distance from a specified reference point, such as the working platform or anchorage of a fall arrest system, to the lower level that a worker might encounter during a fall.

Clearance Requirement
The distance below an authorized person that must remain clear of obstructions in order to ensure that the authorized person does not make contact with any objects that would cause injury in the event of a fall.

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.
Component – An element or integral assembly of interconnected elements intended to perform one function in the system.

Connecting Subsystem
An assembly, including the necessary connectors, comprised of all components, subsystems, or both, between the anchor-age or anchorage connector and the harness attachment point.
Connector
A component or element that is used to couple parts of the system together.

Deceleration Distance
The vertical distance between the user’s fall arrest attachment at the onset of fall arrest forces during a fall, and after the fall arrest attachment comes to a complete stop.
Energy (Shock) Absorber
A component whose primary function is to dissipate energy and limit deceleration forces which the system imposes on the body during fall arrest.

Fall Arrest
The action or event of stopping a free fall or the instant where the downward free fall has been stopped.

Fall Hazard
Any location where a person is exposed to a potential free fall.

Free Fall
The act of falling before a fall protection system begins to apply forces to arrest the fall.

Free Fall Distance
The vertical distance traveled during a fall, measured from the onset of a fall from a walking working surface to the point at which the fall protection system begins to arrest the fall.

Harness, Full Body
A body support designed to contain the torso and distribute the fall arrest forces over at least the upper thighs, pelvis, chest and shoulders.

Horizontal Lifeline
A component of a horizontal lifeline subsystem, consisting of a flexible line with connectors or other coupling means at both ends for securing it horizontally between two anchorages or anchorage connectors.

Horizontal Lifeline Subsystem
An assembly, including the necessary connectors, comprised of a horizontal lifeline component and, optionally, of: a) An energy absorbing component or, b) A lifeline tensioner component, or both. This subsystem is normally attached at each end to an anchorage or anchorage connector. The end anchorages have the same elevation.

Lanyard
A component consisting of a flexible rope, wire rope or strap, which typically has a connector at each end for connecting to the body support and to a fall arrester, energy absorber, anchorage connector or anchorage.

Lanyard Connecting Subsystem
An assembly, including the necessary connectors, comprised of a lanyard only, or a lanyard and energy absorber.

Personal Fall Arrest System (PFAS)
An assembly of components and subsystems used to arrest a person in a free fall.

Positioning
The act of supporting the body with a positioning system for the purpose of working with hands free.

Positioning Lanyard
A lanyard used to transfer forces from a body support to an anchorage or anchorage connector in a positioning system.

Qualified Person
A person with a recognized degree or professional certificate and with extensive knowledge, training and experience in the fall protection and rescue field who is capable of designing, analyzing, evaluating and specifying fall protection and rescue systems.

Self-Retracting Device (SRD)
A device that contains a drum wound line that automatically locks at the onset of a fall to arrest the user, but that pays out from and automatically retracts onto the drum during normal movement of the person to whom the line is attached.

Snaphook
A connector comprised of a hook-shaped body with a normally closed gate or similar arrangement that may be opened to permit the hook to receive an object and, when released, automatically closes to retain the object.

Swing Fall
A pendulum-like motion that occurs during and/or after a vertical fall. A swing fall results when an authorized person begins a fall from a position that is located horizontally away from a fixed anchorage.
