Applications
ACE Instruments full-body harnesses are designed to provide the wearer with maximum comfort while maintain-
ing the highest degree of protection from falls. In order for the harness to be fully effective, it must be adjusted
properly to fit the wearer and attached to an appropriate personal fall arrest system.
A. Personal fall arrest: The full-body harness is used as a component of a personal fall arrest system. Personal
fall arrest systems typically include a full-body harness and a connecting subsystem (energy-absorbing lanyard).
Maximum arresting force must not exceed 1,800 Ibs.
B. Restraint: The full-body harness is used as a component of a restraint system to prevent the user from
reaching a fall hazard. Restraint systems typically include a full-body harness and a lanyard or restraint line.
C. Work positioning: The full-body harness Is used as a component of a work positioning system to support the
user at a work position. Work positioning systems typically include a full-body harness, positioning lanyard and a
back-up personal fall arrest system.
D. Personnel riding: The full-body harness is used as a component of a personnel riding system to suspend or
transport the user vertically. Personnel riding systems typically include a full-body harness, boatswain's chair or
seat board and a back-up personal fall arrest system.
E. Climbing: The full-body harness is used as a component of a climbing system to prevent the user from falling
when climbing a ladder or other climbing structure. Climbing systems typically include a full-body harness,
vertical cable or rail attached to the structure and climbing sleeve.
F. Rescue: The full-body harness is used as a component of a rescue system. Rescue systems are configured
depending on the type of rescue.
Limitations
Full-body harnesses are designed to act in concert with other elements of a personal fall arrest system and
arrest a fall from height while minimizing impact load on the wearer. Users should not combine components or
subsystems from manufacturers other than ACE Instruments unless it is determined by a qualified person that
they are compatible with one another. Incompatible components may interfere with the safe operation or
function of the equipment unless otherwise noted:
Maximum allowable free fall shall not exceed 2m
Maximum user weight not to exceed: 100kg (220 lbs)
Environmental Hazards: Use of this equipment with environmental hazards may require additional precautions
to prevent injury to the user or damage to the equipment. Hazards may include, but are not limited to: heat,
chemicals, corrosive environments, high voltage power lines, gases, moving machinery, moving vehicles and
sharp edges. Contact us if you have questions about using this equipment where environmental hazards may
exist.
Training: This equipment is intended to be used by persons trained in its correct application and use.
Installation & Operation
The personal fall arrest system (PFAS) attached to the full-body harness may only be attached to the dorsal
D-ring. Dorsal D-ring is for fall arrest ONLY. Before using this harness, check to ensure that all components of the
personal fall arrest system are compatible. ACE Instruments recommends using only ACE Instruments equipment
in any system used with an ACE Instruments harness.
ACE Instruments recommends that, when possible, harnesses be issued to individuals for personal use only.
This ensures proper adjustment and fit for the wearer and provides tracking Information. Whenever possible,
choose an
anchorage point that is located directly overhead to reduce the possibility of injury due to swing-fall hazards.
Before each use, users of personal fall arrest systems must have a rescue plan in place, if the users cannot
rescue themselves, as well as the means to carry out the rescue.
Personal energy absorbers and energy-absorbing lanyards must be inspected prior to each use for wear,
damage, and other deterioration. All snap hooks and carabiners on the product must be able to self-close and
lock. All webbing and rope must be inspected for tears, cuts, fraying, abrasion, discolorration, or other signs of
wear and damage. Sewn terminations must be secure, complete and not visibly damaged. All rope splices must
be secure. Cable must be inspected for kinks, broken strands, corrosion, abrasion or other signs of wear and
damage. Swaged terminations must be secure with the thimble tight and not visibly damaged. Load indicators
must not be deployed.
Damaged and other deteriorated or defective components must be immediately removed from service in
accordance with the requirements of EN354:2010.
Anchorages: AII anchorages to which the personal energy absorbers and energy-absorbing lanyards attach
must meet the requirements of EN795:2012
Anchorage Connectors: Anchorage connectors are components that couple the personal fall arrest system
to the anchorage. In accordance with EN362:2004 the anchorage connector must be capable of withstanding
(without breaking) a 2200 kg (22.2 kN) load, and able to withstand a 1600 kg (16 kN) load without cracking or
permanent deformation visible to the unaided eye.
10
The strength of all anchorage connectors must be multiplied by the maximum number of personal fall arrest
systems attached. A mobile anchorage connector should be used to provide lateral mobility and help prevent
the possibility of a swing fall.
Users should take special precautions around moving machinery and around electrical hazards. Improperly
adjusted harnesses and improperly placed PFAS elements can present a danger in these areas.
In the event of a fall, the user must have a rescue plan in place and the means at hand to execute it immediately.
Lanyard Usage Requirements
The illustration below is an example of how to calculate the fall clearance requirements using energy-absorbing
lanyards connected to the dorsal D-ring of a full-body harness. Add the length of the energy-absorbing lanyard
(6 feet (1,8 m)) to the marked maximum elongation of the lanyard during deceleration to the dorsal D-ring height
of the worker (average 5 feet (1,5)). Add 1 foot (0,3 m) for the slide of the dorsal D-ring and a safety factor of
2 feet (0,6 m) to allow for the possibility of an improperly fitted harness, a taller than average worker, and/or a
miscalculation of distances. The total distance from the anchorage is 17 feet (5,33m) for this example.

Free Fall
To calculate the free fall distance using an energy-absorbing lanyard connected to the dorsal D-ring of a
full-body harness and an anchorage connector that is above the workers shoulders, worker (a), subtract the
distance from the dorsal D-ring on the harness to the anchorage connector (5 feet (1,5 m)) from the length of the
energy-absorbing lanyard (6 feet (1,8 m)). The free fall for worker (a) Is 1 (0,3 m) foot. The free fall distance with an
energy-absorbing lanyard connected to the dorsal D-ring of a full-body harness to an anchorage connector that
is at the workers shoulders, worker (b), is equal to the length of the lanyard. The free fall for worker (b) is 6 feet
(1,8 m).
To calculate the free fall distance using an energy-absorbing lanyard connected to the dorsal D-ring of a full-
body harness to an anchorage connector that is below the workers shoulders, worker (c), add the distance from
dorsal D-ring on the harness to the anchorage connector (5 feet (1,5 m)), to the length to the of the energy-
absorbing lanyard (6 feet (1,8 m)). The free fall for worker (c) is 11 feet (3,3 m).
Swing Falls
Work as closely as possible directly underneath the anchorage connector to minimise the possibility of
a swing fall.
WARNING: Striking objects horizontally due to the pendulum effect of a swing fall may cause serious injury
or death.
Swing falls also increase the vertical fall distance of a worker, compared to a fall directly below the anchorage
connector. Swing falls may be reduced by using overhead anchorage connectors that move with the worker.
