2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS:
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
GetPro if you have any questions about compatibility. Self-locking snap hooks and carabi-
ners 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).
2.3 MAKING CONNECTIONS:
GetPro connectors (snap hooks and carabiners) are designed to be used only as specified
in each product's user's instructions. See Figure 6 for inappropriate connections. Getpro
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.
Caution: Ensure all connectors are fully closed and locked.
2.4 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 average arresting force for certified anchorages, or
2. 5,000 pounds (22.2 kN) for non-certified 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 qualified 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 certified anchorages, or
4. 3,000 pounds (13.3 kN) for non-certified anchorages.
