FallTech DuraTech 6' Single/Twin Self‐Retracting Device User Manual
NOTE: Attachment to any anchorage other than directly overhead will require additional fall clearance distance and swing fall clearance. Lateral movement
will result in a significant increase to fall clearance distance and swing fall requirements. See Section 4.
2.4 Application Limits: Take action to avoid moving machinery, sharp edges, abrasive surfaces, and thermal, electrical and chemical hazards as contact may
cause serious injury or death.
DO NOT attach to a foot‐level anchorage.
DO NOT use the SRD to lift tools, materials, or personnel.
Remove from service any equipment subjected to fall arrest forces.
3. SYSTEM REQUIREMENTS
3.1 Capacity: To maintain ANSI Z359 compliance, limit user weight to a range of 130‐310 lbs.
(58.9‐140.6 kg), including clothing, tools, etc.
3.2 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. Non‐compatible connectors may unintentionally disengage. Connectors must be compatible in size, shape, and strength.
Self‐closing, self‐locking snap hooks and carabiners are specified by OSHA and ANSI Z359.12. FallTech offers a wide variety of connectors for use with the 6'
SRD. See Table 1‐B and Table 1‐C.
3.3 Compatibility of Components: Equipment is designed for use with approved components and subsystems only. Substitutions or replacements made
with non‐ ANSI Z359 compliant components or subsystems may jeopardize compatibility of equipment and may affect the safety and reliability of the
complete system. Ensure compatibility between the connectors if non‐FallTech components are used for fall protection.
3.4 Making Connections: Only use self‐locking snap hooks, rebar hooks, and carabiners 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
close and lock completely. Connectors (snap hooks, rebar hooks, and carabiners) are designed for use only as specified in this manual. See Figure 13 in
3.5 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., a SAL, an SRD, or a Fall Arrester Connecting Subsystem (FACSS)
attached to the dorsal D‐ring of the FBH. PFAS components used with this equipment must meet applicable ANSI Z359 requirements and OSHA regulations.
OSHA requires a personal fall arrest system be able to arrest the worker’s fall with a maximum arresting force of 1,800 lbs., and limit the free fall to 6 feet
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.
3.5.1 Average Arrest Force, Arrest Distance: The SRD discussed in this manual is classified by ANSI Z359.14 as a Class B device, which allows for a maximum
arrest distance of 54”. The unit discussed in this manual has an arrest distance of 28”. The SRD discussed in this manual also meets ANSI requirements of an
Average Arrest Force of less than 900 lbs.
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. MRFC is discussed in detail in
3.6 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.
3.7 Definitions: The following are definitions of terms as defined in ANSI Z359.0‐2012.
Authorized Person: A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard (otherwise
referred to as “user” for the purpose of these instructions).
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 may be encountered during a fall or that meet the criteria for a certified anchorage prescribed in this standard.
Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary,
hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate hazards.
Harness Stretch: Amount of vertical travel of the Full Body Harness D‐ring during a fall arrest.
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 to the extent required by
Rescuer: Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.
4. INSTALLATION AND USE
Do not alter or intentionally misuse this equipment. Consult FallTech when using this equipment in combination with components or subsystems other
than those described in this manual.
Do not use rebar hooks, large carabiners or large snap hooks to connect to the FBH dorsal D‐rings or to any small diameter non‐compatible anchor point
as this may cause a roll‐out condition and/or unintentional disengagement.
4.1. Plan the Personal Fall Arrest System (PFAS). Examine the work area and take action to address hazards. See paragraph 2.4. Falls are a serious hazard
when working at height. Training and equipment are the tools of fall hazard management. There are several closely related facets of fall hazard
management with a PFAS;
Minimum Required Fall Clearance (MRFC)
Swing Fall and Expanded Work Zone
Overhead (above the FBH D‐ring) Anchorage
Non‐overhead (below the FBH D‐ring) Anchorage
4.2 Anchorage: Select a suitable anchor point. See paragraph 3.6. Determine the anchor point location relative to the height of the user’s FBH D‐ring. Also,
consider how many feet of lateral travel the work will require.
