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
specifi cally 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.
2.4 CONNECTING SUBSYSTEMS: Connecting subsystems (self-
retracting lifeline, lanyard, rope grab and lifeline, cable sleeve)
must be suitable for your application. See section 1.1. See
subsystem manufacturer's instructions for more information. Some
harness models have web loop connection points. Do not use
snap hooks to connect to web loops. Use a self-locking carabiner
to connect to a web loop. Ensure the carabiner cannot cross-gate
load (load against the gate rather than along the backbone of the
carabiner). Some lanyards are designed to choke onto a web loop
to provide a compatible connection. See Figure 10. Lanyards may
be sewn directly to the web loop forming a permanent connection.
Do not make multiple connections onto one web loop, unless
choking two lanyards onto a properly sized web loop.
2.5 ANCHORAGE STRENGTH: The anchorage strength required
is dependent on the application type. The following are the
requirements of ANSI 359.1 for these application types:
A. FALL ARREST: 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:
1. 5,000 lbs. (22.2 kN) for non-certified anchorages, or
2. Two times the maximum arresting force for certified
anchorages. When more than one fall arrest system is
