2.10 CONNECTING SUBSYSTEMS:
Connecting subsystems (self-retracting lifeline, lanyard, rope grab and
lifeline, cable sleeve) must be suitable for your application (see Table 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 8. 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.

2.11 ANCHORAGE & ANCHORAGE STRENGTH:
Anchorage and anchorage strength requirements are dependent
on the full body harness application (see Figure 3). In accordance with ANSI Z359.1, anchorages selected for Fall
Arrest Systems must meet the anchorage strength requirements de
fi
ned in Table 2.

Climbing
The structure to which a climbing system is attached must sustain the loads required by that
particular system. See the instructions for the climbing system for requirements.
1 Multiple Systems:
When more than one of the de
fi
ned system is attached to an anchorage, the strength de
fi
ned for Non-Certi
fi
ed
or Certi
fi
ed anchorages shall be multiplied by the number of systems attached to the anchorage.
2 Certi
fi
ed Anchorage:
An anchorage for fall arrest, positioning, restraint, or rescue systems that a quali
fi
ed person certi
fi
es to be
capable of supporting the potential fall forces that could be encountered during a fall or that meet the criteria for a certi
fi
ed anchor-
age prescribed in this standard.
