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 non-approved components
or subsystems may jeopardize compatibility of equipment and may affect 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 2. Connectors
must be compatible in size, shape, and strength. Self-locking snap hooks and carabiners are required by
ANSI Z359.1, OSHA, and in Canada, by CSA Z259.12.

2.3 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.

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 could 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 allow 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.

G. In a manner that does not allow the connector to align properly while under load.

Figure 2 - Unintentional Disengagement Figure 3 - Inappropriate Connections

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 self-locking or a non-locking snap hook) to open,
allowing the snap hook or carabiner to disengage from the connecting point.

2.4 ANCHORAGE STRENGTH: The anchorage to which the roof anchor is installed must meet minimum
strength(s) as given below for the applications selected:

Per OSHA 1926.500 and 1910.66: Anchorages used for attachment of personal fall arrest systems (PFAS)

shall be independent of any anchorage being used to support or suspend platforms and capable of
supporting at least 5,000 lbs. 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 under the supervision of a qualifi ed person.

3.0 OPERATION AND USAGE

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

in combination with components or subsystems other than those described in this manual. Some subsystems
and components combinations may interfere with the proper operation of this equipment.

WARNING: Do not use this equipment if you are unable to tolerate the impact from a fall arrest. Age and
fi tness can seriously affect your ability to withstand a fall. Pregnant women and minors must not use this
equipment.

3.1 BEFORE EACH USE of this equipment, carefully inspect it to assure that it is in serviceable condition. Check
for worn or damaged parts. Ensure roof anchor is secure and not distorted. Inspect for sharp edges, burrs,
cracks, or corrosion. Inspect other fall arrest equipment in accordance with manufacturer’s instructions.
Refer to section 5.0 for further inspection details. Do not use if inspection reveals an unsafe condition.

3.2 PLAN your fall arrest system before starting your work. Take into consideration factors affecting your safety
at any time during use. The following list gives some important points you must consider when planning
your system:

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

section 2.4. Locate roof anchor in accordance with section 3.3.

B. OTHER CONSIDERATIONS: Personal fall arrest systems must be rigged to limit any free fall to a

maximum of 6 ft. (1.8 m) per OSHA and ANSI Z359.1. Avoid working above your anchorage level since
an increased free fall distance will result. Avoid working where your line may cross or tangle with that
of other workers or objects. Do not allow the lifeline to pass under arms or between legs. Never clamp,
knot, or prevent the lifeline from retracting or being taut. Avoid a slack line. Do not lengthen an SRL by
connecting a lanyard or other components without consulting DBI-SALA. Should a fall occur, there must
be sufficient clearance in the fall area to arrest the fall before striking the ground or other object. The
total fall distance is the distance measured from the onset of a fall to the point where the fall is arrested.
A number of factors can influence total fall distance including: user’s weight, anchorage location relative
to the fall (swing fall), body support with sliding D-ring, etc.

C. SWING FALLS: Swing falls occur when the anchorage point is not 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. Swing falls can be minimized by working as directly
below the anchorage point as possible. See Figure 4. Also 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. If a swing fall hazard exists in your application, contact DBI-SALA before
proceeding.

D. SHARP EDGES: Avoid working where the connecting subsystem (i.e. self retracting lifeline, full body

harness, etc.) or other system components will be in contact with, or abrade against unprotected sharp
edges. 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. A energy absorbing
component can sometimes be added in-line to further protect the worker. Compatibility and total
fall distance issues must be considered if this is done. Contact DBI-SALA before using in-line energy
absorbing components or lanyards with self retracting lifelines.

E. RESCUE: Should a fall occur, the user (employer) must have a rescue plan and the means at hand to

implement it.

F. AFTER A FALL: Any equipment which has been subjected to the forces of arresting a fall must be

removed from service immediately and destroyed or contact a factory authorized service center for repair.

3.3 INSTALLATION REQUIREMENTS:
A. ROOF ANCHOR SITE PLAN: Before starting the roof construction, a plan should be established as to

where the roof anchor(s) will be installed and when during the construction process they may be used.
The following are guide lines on locating roof anchors:

• The roof anchor should be located at the roof peak and at least 4 ft (1.2 m) and as far away from any
exposed roof edge as possible (see Figure 5). The anchor should be located to avoid swing falls as
discussed in section 3.2 by keeping it near the area where work is taking place. Reposition the roof
anchor, as needed, as work progresses.

• On long low pitched roofs, multiple roof anchors should be installed along gable ends, 4 ft (1.2 m)
from edge to reduce swing fall hazards.

• Very large roofs may require repositioning of the anchor along the roof peak.

• Do not install roof anchors on facia board or unsupported roof structure such as eaves or gable
overhangs.

• Anchors should be installed along the roof ridge on trusses on 24 in. (61 cm) centers only. (See
Figure 6.)

• Anchors are approved for use on roofs ranging in pitch from 4:12 to 12:12 only.

• A maximum of three workers may be anchored to this unit at any time.

B. ROOF FRAMING: Roof framing members to which the roof anchors are attached must be in good

condition. Members must be free of splits, cracks, large knots or other defects that may weaken the
member. Figure 5 shows how the anchor would look once in place. The roof framing structure must be
capable of withstanding the loads given in section 2.4.
