3.5 Restricted Applications:
Not all Full Body Harnesses are built alike, and each product has different features.
There are some applications for which our products may not be ideally suited. Below are a few restrictions to
consider before using your FallTech® Full Body Harness:
3.5.1 Harsh Chemical Environments:
Acids and other caustic chemicals may cause damage to this FBH, its
components and other elements for your Personal Fall Arrest System (PFAS). Damage from chemical exposure can
be difficult to detect and FallTech® recommends inspection before each use and frequent replacement. FallTech®
does manufacture products which are suited to harsh environments. For additional details, please contact
Customer Service or your local FallTech® sales representative.
3.5.2 Arborist Applications:
This product should never be used in arborist applications or tree trimming
applications.
3.5.3 Welding:
FallTech® recommends the use of Aramid webbing FBH’s (Kevlar® or Nomex®) for welding and
other applications where the harness may be exposed to extremely high temperatures.
3.5.4 Heavyweight:
Most FallTech® FBH’s are rated for a maximum capacity of 425 lbs (user, clothing, tools, and
equipment), provided they are used in conjunction with other FallTech® EALs or FallTech® SRLs rated for a
heavyweight user. Be sure to check the product label for the capacity of your specific FallTech® product.
3.5.5 Extended Free Falls:
FallTech® FBH’s are rated for a maximum free fall of 6 feet. FallTech® FBH’s may be
used in applications where there may be exposure to free falls of up to 12 feet, provided that a properly rated
FallTech® energy absorbing lanyard is used.
4.1 Capacity:
To maintain ANSI Z359 compliance, limit user weight to a range of 130-310 lbs. (59-140 kg), includ
-
ing clothing, tools, etc. To maintain CSA Z259 compliance, limit user weight to a range of 120-350 lbs. (54-160 kg),
including clothing, tools, etc.
4.2 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 open inadvertently regardless of how they become oriented. 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 2 for some examples of incorrect connections.
4.0 System Requirements
Equipment is designed for use with approved components and subsystems only. Substitutions or replacements
made with non-ANSI Z359 or CSA Z259 compliant components or subsystems may jeopardize compatibility of
equipment and may affect the safety and reliability of the complete system. Ensure a competent persons assess
the compatibility between the connectors if non-FallTech components are used for fall protection.
Figure 2 - Incorrect 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 a 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 carabiners 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.
