EN
Important: Before use, read and understand all the
safety information and instructions listed in this manual
and the manuals for any additional safety equipment
being used in conjunction with this harness.
The product must be thoroughly inspected before EVERY
use; see 8. Inspection Instructions.
6.1 Dorsal Attachment Point
(Fig.1 – Fig.2)
1 Fig.
2 Fig.
• The point marked with ‘A’ is used only with a fall arrest
system combined with an energy absorber lanyard
(82473), safety karabiner (82472).
• ONLY the karabiner should be connected to the
harness.
6.2 Required Ground Clearance (Fig.3)
3 - Example ground clearance calculationFig.
Important: It is ESSENTIAL that the required ground
clearance is calculated before EVERY use. The required
ground clearance is the minimum distance required
between the anchor point and the nearest lower level.
There must be no obstacles present within this distance,
ensuring that the user can fall unimpeded without
impacting on the ground or other intermediate object.
Ground clearance is calculated between from the anchor
point. The total required ground clearance is calculated
by adding together the following values:
• Lanyard length (LL):
The total vertical distance below the anchor point that
the user will fall before the lanyard begins to arrest the
fall. The 82473 lanyard is xed at 1.82m in length (round
to 2m).
• Deceleration distance (DD):
Accounts for the extension of the energy absorber and
displacement and stretching of the harness.
• User height (UH):
The height of the user.
• Safety clearance (SC):
A minimum clearance value to prevent the user’s feet
from contacting the ground or platform. This value must
be at least 1m.
Required ground clearance: 6.5m
Important: These values are calculated using a body
mass of 100kg. Where the body mass of the user exceeds
this value or their height exceeds 2m, the calculation
must take into account these dierences. A greater
safety clearance distance is required for users of over
100kg.
Important: Keep in mind that the free fall distance (the
distance that the harness attachment travels from the
start of the fall until the lanyard begins its arrest) will vary
according to the position of the anchor point in relation
to the working level. An increased free fall distance will
apply greater force to the fall arrest system than one that
is lower. This is known as Fall Factor.
Important: Also assess the likelihood of injury from
swing falls in which the user does not fall directly
downwards. Swing falls occur when the anchor point is
not vertically aligned with the body, causing the user to
arc towards around the anchor point when falling. Ensure
that the surrounding area is free from any obstructions
that might impede a swing fall.
