BODY SUPPORT: A Full Body Harness must be used with the Self-Retracting Device. The harness connection point must be
above the user's center of gravity. A body belt is not authorized for use with the Self-Retracting Device. If a fall occurs when
using a body belt it may cause unintentional release or physical trauma from improper body support.
2.5
COMPATIBILITY OF COMPONENTS: Unless otherwise noted, 3M equipment is designed for use with 3M approved
components and subsystems only. Substitutions or replacements made with non approved components or subsystems may
jeopardize compatibility of equipment and may affect safety and reliability of the complete system. Follow manufacturer's
instructions for components and subsystems in your personal fall arrest system.
2.6
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 3M if you have any questions about compatibility.
Connectors used to suspend the SRD must comply with EN362. 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 4). Connectors must be compatible in size, shape, and strength. Self-locking snap hooks and
carabiners are required. If the connecting element to which a snap hook 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 (A).
This force may cause the gate to open (B), allowing the snap hook or carabiner to disengage from the connecting point (C).
2.7
MAKING CONNECTIONS: Snap hooks and carabiners used with this equipment must be self-locking. 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. 3M connectors (snap hooks and carabiners) are designed to be used only as
specified in each product's user's instructions. See Figure 5 for examples of inappropriate connections. Do not connect
snap hooks and carabiners:
A.
To a D-ring to which another connector is attached.
B.
In a manner that would result in a load on the gate. 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 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.
