2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS:
DBI-SALA equipment is designed for use
with DBI-SALA 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:
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 DBI-SALA if
you have any questions about compatibility. Connectors (hooks, carabiners, and
D-rings) must be capable of supporting at least 5,000 lbs. (22.2kN). 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 2). Connectors must be compatible in size,
shape, and strength. Self-locking snap hooks and carabiners are required by CE,
ANSI Z359.1 and OSHA.
Figure 2 - Unintentional Disengagement (Roll Out)
If the connecting element that a snap hook (shown) or carabiner attaches to 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.
Small ring or other
non-compatibly
shaped element
1. Force is applied to
the snap hook.
2. The gate presses against
the connecting ring.
3. The gate opens allowing
the snap hook to slip off.
2.3 CONNECTIONS:
Only use self-locking snap hooks and carabiners with this
equipment. Only use connectors that are suitable to each application. 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.
DBI-SALA connectors (snap hooks and carabiners) are designed to be used only
as specified in each product’s user instructions. See Figure 3 for inappropriate
connections. DBI-SALA 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.
