D. To each other.

and connector specifically allows such a connection).

ANCHORAGE STRENGTH
: The anchorage strength required is dependent upon the application. The following
lists guidelines for specific application types:
A.
FALL ARREST
: Anchorages selected for personal fall arrest systems (PFAS) shall have a strength capable
of sustaining static loads, applied in the directions permitted by the PFAS, of at least: (A) 3,600 lbs. (16 kN)
when certification exists (see CSA259.2.5-2017 for certification definition), or (B) 5,000 lbs. (22.2 kN) in the
absence of certification. When more than one PFAS is attached to an anchorage, the anchorage strengths set
forth in (A) and (B) above shall be multiplied by the number of personal fall arrest systems attached to the
anchorage.
Per 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 factory of at least two, and is supervised by a qualified person.
Note: When more than one Fall Arrest system is attached to an anchorage, the strength specified above shall
be multiplied by the number of systems attached to the anchorage
B.
RESTRAINT
: Anchorages must be capable of supporting a minimum of 3,000 lbs. per system attached.
2.5
LIFELINES
: Lifelines used are: 5/8-inch (16mm) diameter polyester/polypropylene blend rope assembly,
5/8-inch (16mm) diameter polyester/polypropylene blend rope. See Section 7.0 for lifeline specifications and
Section 7.3 for elongation factors.
FIGURE 3 - UNINTENTIONAL DISENGAGEMENT
FIGURE 4 - INAPPROPRIATE CONNECTIONS
If the connecting element to which a snap hook (shown)
or carabiner attaches is undersized or irregular in shape, a
situation could occur where the connecting element applies a
force to the gate snap hook or carabiner. the 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.
