WARNING!
RESCUE AND EVACUATION: the user must have a rescue plan and the means at hand to implement it. The plan must take
into account the equipment and specific training necessary to affect prompt rescue under all foreseeable conditions.
Suspension intolerance, also called suspension trauma or orthostatic intolerance, is a serious condition. Prompt rescue and
use of post fall suspension relief devices can help to reduce the likelihood of suspension intolerance. If the rescue be from a
confined space, the provisions of OSHA regulation 1910.146 and ANSI Z117.1 must be taken into account. It is recommended
to provide means for user evacuation without assistance of others. This will usually reduce the time to get to a safe place and
reduce or prevent the risk to rescuers.
Failure to follow this warning can result in serious personal injury or death.

Description
2.1
Attachment Elements (D-Rings)
When soft loops are present, it is recommended that these attachments only be connected with other soft loops or carabiners.
2.1.1
Fall Arrest Attachment (Qty 1)
Also called back D-Ring and present on all MSA harnesses. For fall arrest. The back D-Ring may also be used as an
attachment element for travel restriction.
2.1.2
Hip Attachments (Qty 2, If Present)
Also called hip D-Rings. For restraint (work positioning and travel restriction) . Never use the hip D-Rings for fall arrest or for
climbing protection. Always use both hip D-Rings together, for work positioning applications. "N2" marking on or near D-Rings
indicates these connectors must be used as a pair. When work positioning, use a separate fall arrest system attached to the
back D-Ring.
2.1.3
Front Attachment other than Sternal (Qty 1, if present)
For controlled descent, lifting and lowering (by hoisting), and for ladder climbing protection systems (provided the potential free
fall distance is very short, footing can be easily gained, and there is no chance to fall in a direction other than feet first). The
chest D-Ring may also be used for rescue, retrieval, and evacuation.
2.1.4
Shoulder Attachments (Qty 2, if present)
Also called shoulder D-Rings. For rescue and retrieval lifting and lowering (by hoisting). Never use the shoulder D-Rings for fall
arrest or climbing protection. Use both shoulder D-Rings together, never only one. "N2" marking on or near D-Rings indicates
that these connectors must be used as a pair.
2.1.5
Back D with integral shock absorber (Qty 1, if present)
Integral shock absorbers are sewn into the harness with a D-Ring on both ends of the pouch. If the shock absorber shows any
signs of activation DO NOT USE THE HARNESS.
2.1.6
Sternal Attachment (Qty 1, if present)
Also called chest attachments. Sternal attachments may be used as an alternative fall arrest attachment in applications where
the dorsal attachment is determined to be inappropriate by a competent person, and where there is no chance to fall in a
direction other than feet first. The sternal attachment element should be used only when the likely fall distance is not greater
than 2 ft (0.6 m). The sternal attachment may also be used for travel restraint, or rescue for controlled descent, lifting and
lowering (by hoisting), and for ladder climbing protection systems.
