1.0 APPLICATIONS
1.1 PURPOSE: DBI-SALA ExoFit and ExoFit XP full body harnesses are
to be used as components in personal fall arrest, restraint, work
positioning, climbing, or rescue systems. See Figures 1 and 2 for
harness styles.
Harnesses included in this manual are full body harnesses and
meet ANSI Z359.1 and OSHA requirements. See Figure 3 for
application illustrations.
WARNING: Working at height has inherent risks. Some risks are
noted here but are not limited to the following: falling, suspension/
prolonged suspension, striking objects, and unconsciousness. In the
event of a fall arrest and/or subsequent rescue (emergency) situation,
some personal medical conditions may affect your safety. Medical
conditions identied as risky for this type of activity include but are not
limited to the following: heart disease, high blood pressure, vertigo,
epilepsy, drug or alcohol dependence, psychiatric illness, impaired
limb function and balance issues. We recommend that your employer/
physician determine if you are t to handle normal and emergency use
of this equipment.
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,

with a frontal D-ring in the sternal location may be used
for fall arrest on xed ladder climbing systems. These are
dened in ANSI A14.3.
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.
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.
E. 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:
7
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. (191 kg) 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
(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 inches (.5 m) 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 4. There must be sufficient
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 5.
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 significantly
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 work
seat, 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.

TRAINING: This equipment must be installed and used by
persons trained in its correct application and use. See section 4.0.
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.
1.3
Refer to national Standards including ANSI Z359 (.0, .1, .2, .3, and
.4) family of standards on fall protection, ANSI A10.32, and applicable
local, state and federal (OSHA) requirements governing occupational
safety for more information about work positioning systems.
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.
9
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. (22.2kN). 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 6. Connectors must be
compatible in size, shape, and strength. Self locking snap hooks
and carabiners are required by ANSI Z359.1 and OSHA.
2.3 MAKING CONNECTIONS: Only self-locking snap hooks and/or
carabiners shall be used with this equipment. Ensure all connectors
are fully closed and locked and compatible.
DBI-SALA connectors (snap hooks and carabiners) are designed to
be used only as specied in each product’s user instructions. See
Figure 3 for inappropriate connections. DBI-SALA snap hooks and
carabiners should not be connected:
A. To a D-ring which another connector is already attached.
B. In a manner that would result in a load on the gate.
Figure 6 - Unintentional Disengagement (Roll-out)
If the connecting element that a snap hook (shown) or carabiner attaches to 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 self-locking or a non-locking snap hook) to
open, allowing the snap hook or carabiner to disengage from the connecting
point. For ANSI Z359.1-2007 compliant hooks, there are no restrictions on the
size or shape of the mating connector provided the snap hook is free to align
with the applied load as intended.
Small ring or other
non-compatibility
connector
1. Force is applied to
the snap hook.
2. The gate presses against
the connecting ring.
3. The gate opens
allowing the snap hook
to slip off.
