the mating receptor on you right hip, and adjust the Leg Strap for a snug comfortable fit (see Section 3.3 for buckle

be centered on your lower chest, 6 in. (15 cm) down from the shoulders. The back Dorsal D-Ring should be centered
between your Shoulder Blades. The front Sternal D-Ring, if present, should be located laterally within 2 in. (51 mm)
of the vertical centerline of the harness (see Section 3.6 for Store-Away D-Ring adjustment).
3.7
USE OF FALL ARREST D-RING OR ATTACHMENT ELEMENT: For Fall Arrest applications connect to the Dorsal
D-ring or attachment element on your back, between your shoulder blades. Side D-rings, if present, are for Positioning
or Restraint applications only. Shoulder D-rings are for Rescue or Retrieval applications only. The front Sternal D-ring is
for Ladder Climbing or Positioning. D-rings on a Suspension Seat are for Suspension or Positioning applications only. (See
Section 1.1.).
3.8
MAKING CONNECTIONS: When using a hook to connect to an anchorage or when coupling components of the system
together, ensure roll-out cannot occur. Roll-out occurs when interference between the hook and mating connector causes
the hook gate to unintentionally open and release. Self-locking snap hooks and carabiners should be used to reduce the
possibility of roll-out. Do not use hooks or connectors that will not completely close over the attachment object. See
subsystem manufacturer's instructions for more information on making connections.
3.9
CONNECTING SYSTEM COMPONENTS: After fitting the ExoFit NEX Harness the user may then connect to other
system components. Follow the guidelines in Section 2 and the manufacturer's instructions included with the component.
3.10 SUSPENSION TRAUMA STRAP: The ExoFit NEX Full Body Harness is equipped with Suspension Trauma Straps (Figure
12 to help prolong allowable suspension time in the event of a fall from height. They should only be used in situations
where a fall has occurred or for training. To use the Suspension Trauma Straps:
1.
Unzip the Trauma Strap Pouch on each hip of the harness and deploy the Suspension Straps (Figure 12A).
2.
Raise the ends of the straps to access the hook and loops. Insert the hook into the loop that provides the desired
strap length.
3.
Lower the Suspension Strap and step onto the strap to alleviate pressure of the harness leg straps on the legs (Figure
12B). Adjust the hook/loop combination for optimal comfort.
;
Maintain an upright position following suspension. Do not lay down. Seek medical attention following a suspension.
