Compatibility Of Connectors; Making Connections - 3M 3320030 Manual Del Usuario

Type of Use Application Examples
Infrequent to Light Rescue and Confined Space, Factory Maintenance
Moderate to Heavy Transportation, Residential Construction, Utilities,
Warehouse
Severe to Continuous Commercial Construction, Oil and Gas, Mining
Multiple Descents Training with the Self-Rescue TRAINING System only
2.3 BODY SUPPORT: A Full Body Harness must be used with the Self-Rescue System. The EZ-Link™ D-Ring on the
Self-Rescue System must be above the user's center of gravity. A body belt is not authorized for use with the
Self-Rescue System. If a fall occurs when using a body belt it may cause unintentional release or physical trauma
from improper body support.
2.4 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.
L IMPORTANT: Follow manufacturer instructions for all components and subsystems in the personal fall
arrest system.
2.5 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. 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 3). Connectors must be compatible in size, shape, and strength. Self-locking snap
hooks and carabiners are required.
2.6 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 instructions. See Figure 4 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.
L NOTe: 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 the snap hook to verify that it is
appropriate for the application.
C. Where the size or shape of the mating connectors are not compatible and, without visual confirmation of proper
connection, may create the false impression of being properly connected.
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.
