• Chest strap is positioned in mid-chest area as specified.
Helpful Hint: When not in use, Honeywell recommends hanging the harness by its back D-ring to help it keep its shape and provide
the worker with a starting point when next donning the harness.
3.2.1. Donning a Pullover Front DRing Harness
1. If leg straps are connected, release straps by unbuckling.
2. Hold harness by back D-ring and rotate so that the front D-ring is facing you.
3. Grasp shoulder straps directly below the front D-ring with both hands. Place head through center of harness between the front
and back D-rings.
4. Spin the harness 180 degrees and adjust harness so that the shoulder straps run vertically over the chest, the front D-ring is
positioned in the mid-chest area, and the back D-ring is located in the middle of the back between the shoulder blades.
5. Pull leg strap between legs and connect to corresponding end. Repeat with second leg strap. Tighten leg straps so that they are
snug, but not so snug as to obstruct normal blood circulation in the legs.
6. Using the friction buckles, adjust shoulder straps until snug.
7. Readjust harness fit as needed so that harness is snug but allows full range of movement. Secure excess strap in elastic loop
keepers.
8. Verify correct harness fit (see Step 8, 3.2 Donning a Harness).
3.2.2. Donning a Ms. Miller Harness (570 / E570)
1. Hold harness by back D-ring. Shake harness to allow all straps to fall in place.
2. If chest and leg straps are connected, release straps by unbuckling.
3. Holding harness by the shoulder straps, step through the waist strap and slip shoulder straps over shoulders so that the back
D-ring is located in the middle of the back between shoulder blades.
4. Pull leg strap between legs and connect to corresponding end. Repeat with second leg strap. Tighten leg straps so that they are
snug, but not so snug as to obstruct normal blood circulation in the legs.
5. Tighten waist strap. Waist strap should be snug, but not binding.
6. Connect chest strap and position in midchest area 6” (152mm) to 8” (203mm) below the trachea but not below the sternum.
Tighten to keep shoulder straps taut.
7. After all webbing straps have been buckled, readjust harness fit as needed so that harness is snug but allows full range of
movement. Secure excess strap in elastic loop keepers.
8. Verify correct harness fit (see Step 8, 3.2 Donning a Harness).

4 USING A FULLBODY HARNESS
4.1 Use of Attachment Elements (DRings/Web Loops) [See Table 2]
4.1.1. Dorsal Attachment Element - Back DRing/Web Loop [See Fig. 7a, 7b & 7c in Appendix A]
The dorsal attachment element or back D-ring/web loop shall be used as the primary fall arrest attachment, unless the application
allows for the use of an alternate attachment. The dorsal attachment may also be used for travel restraint or rescue.
When supported by the dorsal attachment during a fall, the design of the full-body harness shall direct load through the shoulder
straps, supporting the user, and through the thighs. Supporting the user, post fall, by the dorsal attachment will result in an upright
body position with a slight lean to the front with some slight pressure to the lower chest. Considerations should be made when
choosing a sliding versus fixed dorsal attachment element. Sliding dorsal attachments are generally easier to adjust to different
user sizes, and a allow a more vertical rest position post fall, but can increase full-body harness stretch.
CAUTION: Due to the nature of soft loop connections, it is recommended that only soft loops and carabiners be used to connect
to soft loop attachments. Connecting snap hooks to soft loops is not a preferred connection. However, if a snap hook is used to
connect to a soft loop, the snap hook must be ANSI compliant with a gate strength of at least 3,600 lbs. (16 kN). (Current CSA
standards do not allow the use of snap hooks with soft loops.)
4.1.2. Sternal Attachment Element - Chest Area Front DRing [See Fig. 8a & 8b in Appendix A]
The sternal attachment 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. Free
fall shall be limited to 2 ft. (0.6m). Accepted practical uses for a sternal attachment include, but are not limited to, ladder climbing
with a guided type fall arrester, ladder climbing with an overhead self-retracting lifeline for fall arrest, work positioning, and rope
access. The sternal attachment may also be used for travel restraint or rescue.
When supported by the sternal attachment during a fall, the design of the full-body harness shall direct load through the shoulder
straps, supporting the user, and around the thighs. Support the user, post fall, by the sternal attachment will result in roughly a
sitting or cradled body position with weight concentrated on the thighs, buttocks and lower back. Supporting the user during work
positioning by this sternal attachment will result in an approximate upright body position.
If the sternal attachment is used for fall arrest, the competent person evaluating the application should take measures to ensure
that a fall can only occur feet first. This may include limiting the allowable free fall distance. It may be possible for a sternal
attachment incorporated into an adjustable style chest strap to cause the chest strap to slide up and possibly choke theuser
during a fall, extraction, suspension, etc. The competent person should consider full-body harness models with a fixed sternal
