Making Connections - 3M DBI SALA 2100185 Instrucciones De Uso

2.4 HAZARDS: Use of this equipment in areas with environmental hazards may require additional precautions to prevent injury to the user or
damage to the equipment. Hazards may include, but are not limited to: heat, chemicals, corrosive environments, high voltage power lines,
explosive or toxic gases, moving machinery, sharp edges, or overhead materials that may fall and contact the user or Personal Fall Arrest
System.
2.5 FALL CLEARANCE: Figure 3 illustrates the components of a Fall Arrest. There must be sufficient Fall Clearance (FC) to arrest a fall before
the user strikes the ground or other obstruction. Clearance is affected by a number of factors including: Anchorage Location, (A) Lanyard
Length, (B) Lanyard Deceleration Distance or SRD Maximum Arrest Distance, (C) Harness Stretch and D-Ring/Connector Length and
Settling. Refer to the instructions included with your Fall Arrest subsystem for specifics regarding Fall Clearance calculation.
2.6 SWING FALLS: Swing Falls occur when the anchorage point is not directly above the point where a fall occurs (see Figure 4). The force of
striking an object in a swing fall may cause serious injury or death. Minimize swing falls by working as directly below the anchorage point as
possible. Do not permit a swing fall if injury could occur. Swing falls will significantly increase the clearance required when a Self-Retracting Device
or other variable length connecting subsystem is used.
2.7 COMPONENT COMPATIBILITY: 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 the safety
and reliability of the complete system.
2.8 CONNECTOR COMPATIBILITY: 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 (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 5). Connectors must be compatible in size, shape, and strength. 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).
Self-locking snap hooks and carabiners are required by ANSI Z359 and OSHA.
2.9 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 6 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 complies 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.
