1.0 APPLICATIONS
1.1 PURPOSE: DBI-SALA full body harnesses are to be used as
components in personal fall arrest, restraint, work positioning, or
rescue systems. See Figures 1, 2, 3, and 4 for harness styles.
Harnesses included in this manual are full body harnesses and
meet ANSI Z359.1, OSHA, and CSA Z259.10 requirements. See
Figure 5 for application illustrations.
• Full body harnesses with Kevlar web should be used when
working with tools, materials, or environments of high
temperature (foundries, chemical manufacturing, steel
fabrication, emergency rescue services, re services, welders,
oil industry, nuclear industry, explosives).
• Harnesses with PVC coated hardware should be used when
working in explosive or electrically conductive environments, or
where surfaces must be protected from the hardware.
• Harnesses with high visibility webbing should be used when
increased visibility of the user is required.
A. PERSONAL FALL ARREST: The full body harness
is used as a component of a personal fall arrest
system. Personal fall arrest systems typically
include a full body harness and a connecting
subsystem (energy absorbing lanyard). Maximum
arresting force must not exceed 1,800 lbs (8
kN).For fall protection applications connect the
fall arrest subsystem (example: lanyard, SRL,
energy absorber, etc.) to the D-ring or attachment
element on your back, between your shoulder
blades.
B. WORK POSITIONING: The full body harness
is used as a component of a work positioning
system to support the user at a work position.
Work positioning systems typically include a full
body harness, positioning lanyard, and a back-up
personal fall arrest system. For work positioning
applications, connect the work positioning
subsystem (example: lanyard, Y-lanyard, etc.)
to the lower (hip level) side or belt mounted
work positioning attachment anchorage elements
(D-rings). Never use these connection points for
fall arrest.

C. LADDER CLIMBING: The full body harness
is used as a component of a climbing system
to prevent the user from falling when climbing
a ladder or other climbing structure. Climbing
systems typically include a full body harness,
vertical cable or rail attached to the structure, and
climbing sleeve.For ladder climbing applications,
harnesses equipped with a frontal D-ring in the
sternal location may be used for fall arrest on
xed ladder climbing systems. These are dened
in Z259.2.1 in Canada and ANSI A14.3 in the
United States.

D. RESCUE: The full body harness is used as a
component of a rescue system. Rescue systems
are configured depending on the type of rescue.
For limited access (conned space) applications,
harnesses equipped with D-rings on the shoulders
may be used for entry and egress into conned
spaces where worker prole is an issue.
9
E. CONTROLLED DESCENT: For controlled descent
applications, harnesses equipped with a single
sternal level D-ring, one or two frontal mounted
D-rings, or a pair of connectors originating below
the waist (such as a seat sling) may be used for
connection to a descender or evacuation system
(reference in Z259.10 in Canada).
F. RESTRAINT: The full body harness is used as a component
of a restraint system to prevent the user from reaching a fall
hazard. Restraint systems typically include a full body harness
and a lanyard or restraint line.
1.2 LIMITATIONS: Consider the following application limitations
before using this equipment:
A. CAPACITY: These full body harnesses are designed for use
by persons with a combined weight (clothing, tools, etc.) of no
more than 420 lbs. Make sure all of the components in your
system are rated to a capacity appropriate to your application
B. FREE FALL: Personal fall arrest systems used with this
equipment must be rigged to limit the free fall to 6 feet (1.8
M) (ANSI Z359.1). Restraint systems must be rigged so that
no vertical free fall is possible. Work positioning systems must
be rigged so that free fall is limited to 2 feet (.6 m) or less.
Personnel riding systems must be rigged so that no vertical
free fall is possible. Climbing systems must be rigged so that
free fall is limited to 18 in. (.46 cm) or less. Rescue systems
must be rigged so that no vertical free fall is possible. See
subsystem manufacturer’s instructions for more information.
C. FALL CLEARANCE: See Figure 6. There must be sufcient
clearance below the user to arrest a fall before the user strikes
the ground or other obstruction. The clearance required is
dependent on the following factors:
• Elevation of anchorage
• Connecting subsystem length
• Deceleration distance
• Free fall distance
• Worker height
• Movement of harness attachment element
See subsystem manufacturer’s instructions for more information.

D. SWING FALLS: See Figure 7. Swing falls occur when the
anchorage point is not directly above the point where a fall
occurs. The force of striking an object in a swing fall may
cause serious injury or death. Minimize swing falls by working
as close to the anchorage point as possible. Do not permit
a swing fall if injury could occur. Swing falls will signicantly
increase the clearance required when a self-
retracting lifeline or
other variable length connecting subsystem is used.
E. EXTENDED SUSPENSION: A full body harness is not
intended for use in extended suspension applications. If the
user is going to be suspended for an extended length of time
it is recommended that some form of seat support be used.
DBI-SALA recommends a seat board, suspension workseat,
seat sling, or a boatswain chair. Contact DBI-SALA for more
information on these items.

F. 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; heat, chemicals,
corrosive environments, high voltage power lines, gases,
moving machinery, and sharp edges.
G. HARNESSES FOR HIGH TEMPERATURE ENVIRONMENTS:
Harnesses with Kevlar webbing are designed for use in high
temperature environments, with limitations: Kevlar webbing
begins to char at 800° to 900° Fahrenheit. Kevlar webbing
can withstand limited contact exposure to temperatures up to
1,000° F. Polyester webbing loses strength at 300° to 400° F.
PVC coating on hardware has a melting point of approximately
350° F.
11
IMPORTANT: When working with tools, materials, or in high
temperature environments, ensure that associated fall protection
equipment can withstand high temperatures, or provide protection for
those items.
IMPORTANT: Although PVC coated, cadmium, or zinc plated hardware
exhibit excellent corrosion resistance in chemical, acidic, alkaline, and
atmospheric conditions, frequent inspections may be required. Consult
with DBI‑SALA if you question the use of this equipment in hazardous
environments.
H. TRAINING: This equipment must be installed and used by
persons trained in its correct application and use. See section
4.0.
1.3 APPLICABLE STANDARDS: Refer to national standards, including
ANSI Z359 (.0, .1, .2, .3, and .4) family of standards on fall
protection, ANSI A10.32, CSA Z259.10, and applicable local, state
and federal (OSHA) requirements governing occupational safety for
more information about work positioning systems.
IMPORTANT: Harnesses with Kevlar webbing do not meet ANSI
Z359.1. Kevlar does not have equivalent abrasion resistance of
polyamides. Kevlar harnesses meet all other requirements of this
standard.
2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS: DBI-SALA equipment
is designed for use with DBI-SALA approved components and
subsystems only. Substitutions or replacements made with nonapproved components or subsystems may jeopardize compatibility
of equipment and may effect the safety and reliability of the
complete system.
2.2 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 DBI-SALA if you
have any questions about compatibility.
Connectors (hooks, carabiners, and D-rings) must be capable
of supporting at least 5,000 lbs. (22.2 kN). 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 8.
Connectors must be compatible in size, shape, and strength. Selflocking snap hooks and carabiners are required by ANSI Z359.1
and OSHA.
12
2.3 MAKING CONNECTIONS: Use only self-locking snap hooks and
carabiners with this equipment. Use only 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. Ensure all connectors are fully closed and locked.
DBI-SALA connectors (snap hooks and carabiners) are designed to
be used only as specied in each product’s user’s instructions. See
Figure 9 for inappropriate connections. DBI-SALA snap hooks and
carabiners should not be connected:
A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate.
Figure 8 - Unintentional Disengagement (Rollout)
If the connecting element to which a snap hook (shown) or carabiner
attaches is undersized or irregular in shape, a situation could occur
where the connecting element applies a force to the gate of the snap
hook or carabiner. This force may cause the gate (of either a selflocking or a non-locking snap hook) to open, allowing the snap hook or
carabiner to disengage from the connecting point.

NOTE: Large throat snap hooks should not be connected to standard
size D‑rings or similar objects which will result in a load on the gate
if the hook or D‑ring twists or rotates, unless the snap hook complies
with ANSI Z359.1‑2007 and is equipped with a 3,600 lb gate. Check
the marking on your snap hook to verify that it is appropriate for your
application.
C. In a false engagement, where features that protrude from the
snap hook or carabiner catch on the anchor, and without visual
conrmation seems to be fully engaged to the anchor point.

D. To each other.
E. Directly to webbing or rope lanyard or tie-back (unless the
manufacturer’s instructions for both the lanyard and connector
specically allows such a connection).
F. To any object which is shaped or dimensioned such that the
snap hook or carabiner will not close and lock, or that roll-out
could occur.
2.4 CONNECTING SUBSYSTEMS: Connecting subsystems (selfretracting lifeline, lanyard, rope grab and lifeline, cable sleeve)
must be suitable for your application. See section 1.1. See
subsystem manufacturer’s instructions for more information. Some
harness models have web loop connection points. Do not use
snap hooks to connect to web loops. Use a self-locking carabiner
to connect to a web loop. Ensure the carabiner cannot cross-gate
load (load against the gate rather than along the backbone of the
carabiner). Some lanyards are designed to choke onto a web loop
to provide a compatible connection. See Figure 10. Lanyards may
be sewn directly to the web loop forming a permanent connection.
Do not make multiple connections onto one web loop, unless
choking two lanyards onto a properly sized web loop.
2.5 ANCHORAGE STRENGTH: The anchorage strength required
is dependent on the application type. The following are the
requirements of ANSI 359.1 for these application types:
A. FALL ARREST: Anchorages selected for fall arrest systems
shall have a strength capable of sustaining static loads applied
in the directions permitted by the system of at least:
1. 5,000 lbs. (22.2 kN) for non-certified anchorages, or
2. Two times the maximum arresting force for certified
anchorages. When more than one fall arrest system is
