1.0 APPLICATIONS
1.1 PURPOSE: Energy absorbing lanyards are to be used as components in Personal Fall Protection Systems designed to
safely arrest a fall. See Figure 1 for the energy absorbing lanyard types covered by this instruction. Energy absorbing
lanyards are used in the following applications:
Fall Arrest: Fall arrest systems safely stop the user in a free fall from a height. The user can
then self-rescue or be rescued. Personal fall arrest systems typically include a full body harness
and an energy absorbing lanyard. Maximum arresting force must not exceed 1,800 lbs (8 kN).
Restraint: Restraint systems prevent the user from reaching a fall hazard (example: leading
edge roof work).
Rescue: The energy absorbing lanyard is used as a component of a back-up fall protection
system during rescue or as part of the primary rescue system.
1.2 LIMITATIONS AND REQUIREMENTS:
WARNING: Always consider the following application limitations and requirements before using this equipment.
A. CAPACITY: The EZ-Stop
Energy Absorbing Lanyard
is designed for use by persons with a combined weight (clothing,
tools, etc.) of no more than 310 lbs (141 kg)1. 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 incorporating this equipment must be rigged to limit the free fall to 6 feet
(1.8 m) or less when using EZ-Stop energy absorbing lanyard models, or 12 feet (3.7 m) or less when using EZ-Stop
Force2 and EZ-Stop Leading Edge energy absorbing lanyard models.
C. FALL CLEARANCE: There must be suffi cient clearance below the user to arrest a fall before the user strikes the
ground or other obstruction. The clearance required depends on several factors:
• Deployment distance • Energy absorbing lanyard length • Movement of harness attachment element
• Free fall distance • Elevation of anchorage • Worker height
Figure 2 illustrates fall clearance calculation for an energy absorbing lanyard.
Figure 4 indicates the deployment distance of the personal energy absorber according to the user weight and free
fall distance.
D. SWING FALLS: Swing falls occur when the anchorage point is not directly above the point where a fall occurs (see
Figure 3). Minimize swing falls by working as close to and directly below the anchorage point as possible. Do not
permit a swing fall if injury could occur.
WARNING: The force of striking an object in a swing fall may cause serious injury or death.

(Factors in D-Ring Slide and Harness Stretch.)
Example: Assuming a 6 ft (1.8 m) tall user with a
typical 6 ft (1.8 m) lanyard with 6 ft (1.8 m) Free Fall,
Fall Clearance calculation would be as follows:
RD = LL + DD + HH + C
RD = 6 ft + 4 ft + 6 ft + 1.5 ft = 17.5 ft
RD = 1.8 m + 1.2 m + 1.8 m + 0.5 m = 5.3 m

G. TRAINING: It is the responsibility of the user and the purchaser of this equipment to assure that they are familiar
with these instructions, trained in the correct care and use of, and are aware of the operating characteristics,
application limits, and the consequences of improper use of this equipment.
H. LEADING EDGE: EZ-Stop Leading Edge Energy Absorbing Lanyards have been successfully tested for horizontal
use and for falls over a steel edge without burrs (See Leading Edge models listed in Table 2). As a result, EZ-Stop
Leading Edge Energy Absorbing Lanyards may be used in situations where a fall may occur over similar edges such
as those found on steel shapes or metal sheeting. Avoid working where the lifeline will continuously or repeatedly
abrade against sharp or abrasive edges. Eliminate such contact or protect edges using a heavy pad or other means
I. ARC FLASH: Arc Flash lanyards
designed for use in environments where an arc fl ash (electrical explosion) could occur.
1.3 APPLICABLE STANDARDS: Refer to national standards including the ANSI Z359 family of standards on fall protection,

2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS: Capital Safety equipment is designed for use with Capital Safety 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.
2.2 COMPATIBILITY OF CONNECTORS:
IMPORTANT: Use only connectors that are suitable to each application and are compatible with connecting elements.
• Connectors must be compatible with the anchorage or other system components.
• Connectors must be compatible in size, shape, and strength.
• Non-compatible connectors may unintentionally disengage (see Figure 5).
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 Capital Safety if you have any questions about compatibility.
Self-locking snap hooks and carabiners are required by ANSI Z359.13 and OSHA. Connectors (hooks, carabiners, and
D-Rings) must be capable of supporting at least 5,000 lbs. (22.2 kN). Per ANSI Z359.12, connector gates must be able to
withstand a load of 3,600 lbs (16 kN).
Figure 5 – Unintentional Disengagement Figure 6 – 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.

2.3 MAKING CONNECTIONS: Capital Safety connectors (snap hooks and carabiners) are designed to be used only as
specifi ed in each product’s user’s instructions. See Figure 6 for inappropriate connections.
Capital Safety 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.
WARNING: 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 Z359.12 and is equipped with a
3,600 lb (16 kN) 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 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 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 (unless using Capital Safety snap
hooks that have been specifically designed and tested for these applications). Contact Capital safety for more
information.
CAUTION: Ensure all connectors are fully closed and locked.
2.4 EZ-STOP MODULAR ENERGY ABSORBING LANYARD MODELS: Refer to Operation and Use, Section 3.3 for
instructions on the assembly of the energy absorbing and lanyard components of the EZ-Stop Modular Energy Absorbing
Lanyard system.

2.5 WEB LOOP CONNECTIONS: Some lanyards are designed to choke onto a web loop to provide a compatible connection.
To choke the lanyard on a web loop:
Insert the lanyard web loop through the
web loop or D-Ring on the harness.
Insert the appropriate end of the lanyard
through the lanyard web loop.
Pull the lanyard through the connecting web
loop to secure.
2.6 ANCHORAGE STRENGTH: Anchorages selected for use with the energy absorbing lanyards must have a strength capable
of sustaining the static load requirements of the intended fall protection application:
A. Fall Arrest: Anchorages selected for personal fall arrest systems (PFAS) shall have a strength capable of sustaining
static loads applied in the directions permitted by the system of at least:
1. Two times the average2 arresting force for certifi ed anchorages3, or
2. 5,000 pounds (22.2 kN) for non-certifi ed anchorages.
When more than one fall arrest system is attached to an anchorage, the strengths set forth in (1) and (2) 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 must be independent of any anchorage
being used to support or suspend platforms and must be capable of supporting at least 5,000 lbs. (22.2 kN) per each
attached user. 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.
B. Work Positioning: 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:
3. Two times the foreseeable force for certifi ed anchorages, or
4. 3,000 pounds (13.3 kN) for non-certifi ed anchorages.
When more than one work positioning system is attached to an anchorage, the strengths set forth in (3) and (4)
above shall be multiplied by the number of systems attached to the anchorage.
C. Restraint: Anchorages selected for restraint and travel restraint systems shall have a strength capable of sustaining
static loads applied in the directions permitted by the system of at least:
5. Two times the foreseeable force for certifi ed anchorages, or
6. 1,000 pounds (4.5 kN) for non-certifi ed anchorages.
When more than one restraint or travel restraint system is attached to an anchorage, the strengths set forth in (5)
and (6) above shall be multiplied by the number of systems attached to the anchorage.
D. Rescue: Anchorages selected for rescue systems shall have a strength capable of sustaining static loads applied in
the directions permitted by the system of at least:
7. Five times the foreseeable force for certifi ed anchorages, or
8. 3,000 pounds (13.3 kN) for non-certifi ed anchorages.
When more than one rescue system is attached to an anchorage, the strengths set forth in (7) and (8) above shall be
multiplied by the number of systems attached to the anchorage.
2
Average Arresting Force: ANSI Z359.13 requires 6 ft energy absorbers to have an average arresting force no greater than 900 lbs (4 kN) and a maximum deploy-
ment distance of 18 in. (1.2 m) without exceeding 1,800 (8 kN) maximum arresting force. 12 ft energy absorbers are required to have an average arresting force no
greater than 1,350 lbs (6 kN) and a maximum deployment distance of 60 in. (1.5 m) without exceeding 1,800 (8 kN) maximum arresting force.
3 Certifi ed Anchorage: An anchorage for fall arrest, positioning, or rescue systems that a qualifi ed person certifi es to be capable of supporting the potential fall forces
that could be encountered during a fall or that meet the criteria for certifi ed anchorage prescribed by the associated standard(s).
