and conforms to OSHA regulations only. Dynamic performance test results on the Heavyweight series differ
from the standard SRD. Use the test performance data provided in Table 1B to calculate fall clearance, assess
swing fall hazards, and calculate the additional fall clearance required when using an SRD.
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. Do not attach the single SRD to the FBH with any large‐throat opening
connector such as a rebar hook or large carabiner. Use only standard connectors.
3.3 Compatibility of Components: Equipment is designed for use with approved components and subsystems
only. Substitutions or replacements with non‐FallTech approved 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 Appendix B.
NOTE: Appendix B contains figures and tables applicable to fall protection in general. Appendix B contains
references to ANSI Z359. The FallTech HeavyWeight SRD is not ANSI compliant, Appendix B ANSI references
notwithstanding.
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., an SAL, an SRD, or a Fall Arrester Connecting Subsystem (FACSS), connected to the
dorsal D‐ring of the FBH. PFAS components used with this equipment must meet applicable OSHA regulations.
3.5.1 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:
a) two times the maximum arrest force permitted when certification exists, or
b) 5,000 lbs. (22.2 kN) in the absence of certification.
Table 1B provides performance attribute test data on the three principal parameters (see paragraph 1.1) for
FallTech self‐retracting devices, listed by model number. In certain situations, the qualified person can
determine that a given structure is a suitable anchor point based on a tested arrest distance and tested
maximum arrest force, with a safety factor of two.
3.6 Definitions: The following are definitions of terms.
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 this standard.
