you should be able to breathe properly and experience no pain
while hanging in it for ten minutes.
4 Ensure that the tie-in loop is correctly positioned. The tie-in
loop must not be twisted.
5 Buckles, the tie-in point and tying in knots should also be
checked at regular intervals during use.
6 We recommend using a figure of eight knot for tying in to the
harness.
7a The gear loops are designed to transport up to 5 kg of
equipment.
7b Gear loops must never be used as a tie-in point.
8a Correct use: tying in through harness tie-in point and leg loop
base.
8b Correct use: tying in through the tie-in ring.
8c Incorrect use: tying in at the harness tie-in point only.
8d Incorrect use: tying in through the leg loop only.
9a Correct use: tying in for harnesses with two symmetrical tie-
in points.
9b Caution: if you tie in to just one tie-in point on harnesses with
two symmetrical tie-in points you could risk serious injury or
death.
10 Correct use: tying in for full-body harnesses (Type A) with two
symmetrical tie-in points.
11 Correct use: tying in for harnesses with a single,
lateral tie-in loop.
12a+b For harnesses with a metal D-ring and a tie-in loop, the
harness may be attached at the D ring or the tie-in loop.
13a+b Children's full-body harnesses are only permitted for
people weighing 40 kg in total.
13b+c If the harness is attached using the rear tie-in eyelet, the
two front tie-in loops must be connected by a locking carabiner.
14 Belay devices or carabiners must be attached directly to the
tie-in loop.
15 Via ferrata sets or systems with a tie-in loop must be secured
at the tie-in ring with a girth hitch (lark's foot).
16a If there is a risk that your torso might tip over without any
control, a sit harness (Type C) should only be used in conjunction
with a chest harness (Type D). To connect a chest harness
(Type D) with a sit harness (Type C) knotted webbing with a
minimum strength of 15 kN (3 marking stripes) can be used. The
lower knot should be approximately level with your solar plexus.
16b Alternatively the rope can be routed straight through the
loops on the chest harness.
16c Do not use a chest harness (Type D) without a sit harness
(Type C).
17a Load-bearing screw elements must be checked at regular
intervals to ensure that they are correctly fitted.
