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.
NOTE:
Large throat-opening
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. Large throat
snap hooks are designed
for use on fixed structural
elements such as rebar or
cross members that are not
shaped in a way that can
capture the gate of the hook.
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 carabiners will not close and lock,
or that roll-out could occur.
G.
In a manner that does not allow the connector to align with the fall arrest device (i.e., lanyard) while under
load.
2.3 ANCHORAGE STRENGTH:
In accordance with ANSI Z359.1, anchorages selected for fall arrest systems shall
have a strength capable of sustaining static loads applied in the directions permitted by the system of at least:
A.
5,000 pounds (22.2kN) for non-certified anchorages, or
B.
Two times the maximum arresting force for certified anchorages.
When more than one fall arrest system is attached to an anchorage, the strengths set forth in (A) and (B)
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 shall be
independent of any anchorage
being used to support or
suspend platforms, and capable
of supporting at least 5,000 lbs.
(22.2 kN) per user attached,
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
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:
