fall arrest system. Applications for these products include inspection work, construction and demolition, maintenance, oil
production, confi ned space rescue, and similar activities where there exists the possibility of a fall. This equipment is specially
designed to dissipate fall energy and limit fall arrest forces transferred to the body.

1.2 LIMITATIONS: The following application limitations must be considered before using this product:
A. CAPACITY: This equipment is for use by persons with a combined weight (person, clothing, tools, etc.)

of no more than 310 lbs. (140.6 kg). CSA models meet Z25911-05 E4 or E6 classifications. See back
cover for associated capacities and model numbers.

B. PHYSICAL AND ENVIRONMENTAL HAZARDS: Use of this equipment in areas containing physical

or environmental hazards may require that additional precautions be taken to reduce the possibility
of damage to this equipment or injury to the user. Hazards may include, but are not limited to: high
heat, strong or caustic chemicals, corrosive environments, the possibility of electric current flowing

2.0 SYSTEM REQUIREMENTS

2.1 COMPATIBILITY OF CONNECTORS: DBI-SALA equipment is designed for use with DBI-SALA approved

components and subsystems only. Substitutions or replacements made with non-approved components
or subsystems may jeopardize compatibility of equipment and may effect the safety and reliability of the
complete system.

COMPATIBILITY:

use equipment that is not compatible. Non-compatible connectors may unintentionally disengage. See Figure 2.
Connectors must be compatible in size, shape, and strength regardless of orientation. Self-locking snap hooks
and carabiners are required by ANSI Z359.1 and OSHA
compatibility.

Connectors ( hooks, carabiners, and D-rings) must be capable of supporting a tensile load of at least 5,000 lbs. (22.2
kN). Per ANSI Z359.1, connector gates must be able to withstand a load of 3,600 lbs (16 kN): the face of the gate
must withstand 3,600 lbs (16 kN); the side of the gate must withstand 3,600 lbs (16kN), and the minor axis of a
snap hook or carabiner must withstand 3,600 lbs (16 kN), except for those with captive eyes.

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.

Connectors must be compatible with the anchorage or other system components. Do not

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.

2.2 MAKING CONNECTIONS: Only use self-locking snap 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. Ensure all connectors are fully closed and locked.

DBI-SALA connectors (snap hooks and carabiners) are designed to be used only as specifi ed 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 to which another

connector is attached.

Figure 3 - Inappropriate Connections

B. In a manner that would

result in a load on the gate.

NOTE: Large throat-opening
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. Large throat
snap hooks are designed
for use on fi xed structural
elements such as rebar or
cross members that are not
shaped in a way that can
capture the gate of the hook.

C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the

anchor, and without visual confirmation 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 specifically allows such a connection).

F.

To any object which is shaped or dimensioned such that the snap hook or carabiners will not close and lock,

or that roll-out could occur.

G. In a manner that does not allow the connector to align with the fall arrest device (i.e., lanyard) while under

load.

2.3 ANCHORAGE STRENGTH:

have a strength capable of sustaining static loads applied in the directions permitted by the system of at least:

A. 5,000 pounds (22.2kN) for non-certified anchorages, or
B. Two times the maximum arresting force for certified anchorages.

When more than one fall arrest system is attached to an anchorage, the strengths set forth in (A) and (B)

above shall be multiplied by the number of systems attached to the anchorage.

WARNING: Anchorages must be rigid. Large deformations of the anchorage will affect system performance,
and may increase the required fall clearance below the system, which could result in serious injury or death.

From OSHA 1926.500 and 1910.66: Anchorages used for attachment of PFAS shall be independent of

any anchorage being used to support or suspend platforms, and capable of supporting at least 5,000 lbs.
(22.2 kN) per user attached, or be designed, installed, and used as part of a complete PFAS which maintains
a safety factor of at least two, and is supervised by a qualifi ed person
Anchorages selected for work positioning systems shall have a strength capable of sustaining static loads
applied in the directions permitted by the system of at least:

A. 3,000 pounds (13.3kN) for non-certified anchorages, or
B. Two times the foreseeable force for certified anchorages.

When more than one work positioning system is attached to an anchorage, the strengths set forth in (A) and

(B) above shall be multiplied by the number of systems attached to the anchorage.

In accordance with ANSI Z359.1, anchorages selected for fall arrest systems shall

3.0 OPERATION AND USE

WARNING: Do not alter or intentionally misuse this equipment. Consult DBI-SALA when using this equipment

in combination with components or subsystems other than those described in this manual. Some subsystem
and component combinations may interfere with the operation of this equipment. Use caution when using this
equipment around moving machinery, electrical hazards, chemical hazards, and sharp edges. Do not loop the
lanyard around small structural members

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 identifi ed 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 fi t to handle normal and
emergency use of this equipment

3.1 BEFORE EACH USE of this equipment, carefully inspect it to assure that it is in good working condition.

Check for worn or damaged parts. Ensure all hardware is present and secure, and is not distorted or have
any sharp edges, burrs, cracks, or corrosion. Ensure self-locking snap hooks or carabiners work properly.
Inspect rope or webbing for wear, cuts, burns, frayed edges, breaks, or other damage. See section 5.0 for
further inspection details. Do not use if inspection reveals an unsafe condition.

3.2 PLAN your fall protection system before starting your work. Take into consideration factors that affect

your safety before, during, and after a fall. The following list gives some important points to consider when
planning your system:

A. ANCHORAGE: Select a rigid anchorage point that is capable of supporting the required loads. See

section 2.3. The anchorage location must be carefully selected to reduce possible free fall and swing
fall hazards and to avoid striking an object during a fall. The anchorage should be generally level
(horizontal) to prevent the anchorage connector from sliding down an incline when in use, which could
cause serious injury to the user.

.

B. FREE FALL: Personal fall arrest systems must be rigged such that the potential free fall is never greater

than 6 ft. (1.8 m). Avoid working above your anchorage level to avoid an increased free fall distance.

IMPORTANT: Some energy absorbing lanyards, such as EZ Stop® Retrax™ and the Shockwave lanyards, make
use of retracting devices designed to shorten their free length. These devices do not decrease free fall distance

C. FALL ARREST FORCES: The assembled fall arrest system must keep fall arrest forces below 1,800 lbs.

(8.0 kN) when used with a full body harness.

D. FALL CLEARANCE: Should a fall occur, there

must be sufficient clearance in the fall area to
arrest the fall before striking the ground or other
object. Energy absorbers can extend the fall
arrest distance by up to 42 inches (106.7 cm).
Figure 4 shows how to estimate fall clearance
distance when using an energy absorbing lanyard

or energy absorber subsystem. Other factors
may influence the required clearance distances.
For example, using an energy absorbing lanyard

stretch in the lifeline or sliding of the rope grab
on the lifeline during fall arrest. Some full body
harness models incorporate a sliding (positional)
D-ring in the back as the fall arrest attachment,
movement of this D-ring during fall arrest can
increase the fall clearance distance required. Use
caution when assembling system components
that could act to extend the fall arrest distance

directly above the point where a fall occurs. The force of striking an
object while swinging (horizontal speed of the user due to the pendulum
affect) can be great and may cause serious injury. In a swing fall
situation, the total vertical fall distance of the user will be greater than if
the user had fallen vertically directly below the anchorage point. The user
must therefore account for an increase in the total free fall distance and
the area needed to safely arrest the fall. Swing falls can be minimized by
working as directly below the anchorage point as possible. Never permit

Hazard

a swing fall if injury could occur. If a swing fall situation exists in your
application contact DBI-SALA before proceeding. See Figure 5.

F. SHARP EDGES

: Avoid working where the lanyard, subsystem, or other

system components will be in contact with, or abrade against, unprotected
sharp edges.

Do not loop lanyard around small diameter structural members.
If working with this equipment near sharp edges is unavoidable, protection
against cutting must be provided by using a heavy pad or other means over the exposed sharp edge.

G. RESCUE

: The user (employer) must have a rescue plan and the ability to implement it when using this

equipment

H. AFTER A FALL: Lanyards with integral energy absorbers, or energy absorber components which have

been subjected to the forces of arresting a fall must be removed from service and destroyed. See
Figure 18.

WARNING: Read and follow manufacturer’s instructions for associated equipment (full body harness, rope grab,
etc.) used in your fall protection system.

IMPORTANT: For special (custom) versions of this product, follow the instructions herein. If included, see
supplement for additional instructions.

3.3 MAKING CONNECTIONS: See Figure 6 for hook operation. When using a hook to connect to an anchorage,

or when coupling components of the system together, ensure accidental disengagement (roll-out) cannot
occur. Roll-out occurs when interference between a hook and the mating connector causes the hook’s gate
or keeper to accidentally open and release. Roll-out may occur when a hook is connected to an undersized
ring such as an eye bolt or other non-compatible shaped connector. Self-locking snap hooks or self­locking and self-closing gate carabiners should be used to reduce the possibility of roll-out when making
connections. Do not use hooks or connectors that will not completely close over the attachment object. For
