WARNING: D
WALT full body harnesses are to be used as part of personal fall arrest (PFAS), restraint , rescue
E
or work positioning system. Full body harnesses are designed in such a way that they work in sync with
other elements of a personal fall arrest system. While they are designed to arrest a fall from height, they also
minimize the impact load on the wearer. D
of the PFAS manufactured by D
WALT are used in combination. If other manufacturer's equipment is used,
E
then this should be ensured for compatibility by a Competent Person only. If substitutions or replacements are
made with non-approved components of sub systems, then this may severely affect the compatibility of the
equipment, making the complete system unsafe for use.

WALT
full body harnesses are to be used as
E
components in personal fall arrest, restraint, work
positioning and rescue systems. The full body harnesses
included in this manual conform to ANSI Z359.11-2021,
and OSHA. Full body harnesses made of heat resistant
webbing should be used when working with tools,
material and environments of high temperature (e.g.
foundries, welding, fire services, steel fabrication, oil
industry, etc.).
APPLICATION
D
WALT
•
Personal Fall Arrest:
full body
E
harnesses along with a connecting sub system
(e.g. energy absorbing lanyard) typically
constitutes a PFAS. The maximum arresting force
should not be more than 1800 lbs. (8 kN). Only
the dorsal D-ring of the full body harness, D-ring
or the attachment element on the back of the
full body harness, should be connected to the fall
arrest subsystem for fall arrest.
•
Working Positioning: The full body harness
is used to support the user at a work position
hence being used as a component of a work
positioning system. The full body harness
together with a work positioning lanyard
constitutes a work positioning system. Personal
fall arrest system is always used as back up.
For work positioning at height, connect the
work positioning sub system (e.g. positioning
lanyard) to the belt mounted work positioning
attachment anchorage elements (also known as
lateral D-rings), or to hip level side D-rings. These
D-rings should never be used as connection
points for fall arrest.

Restraint: The full body harness constitutes a
component of a restraint system, which prevents
the user from reaching a fall hazard (e.g. edge
of a platform or roof). A full body harness
together with a restraint lanyard or restraint line
constitutes a restraint system.
•
Controlled Descent: For applications of
controlled descent, a full body harness is
connected to a descender or an evacuation
system. Such harnesses are equipped with a
single sternal level D-ring, one or two frontal
D-rings, or a pair of connectors originating
below the waist.
•
Rescue: Configuration of rescue systems is
dependent upon the type of rescue. Harnesses
that are equipped with D-rings on the shoulders
may be used for entry and egress into confined
spaces. Hence, the FBH forms a part of the rescue
system.
•
Ladder Climbing: A climbing system prevents
the user from falling when climbing a ladder or
other climbing structure. A FBH equipped with
frontal D-ring on the sternal location is used
as a component of the climbing system. Other
components of a climbing system includes a
vertical cable or rail attached to the structure
and a climbing sleeve.
PRE- INSPECTION CHECK OF THE
HARNESS
The harness should be inspected prior to each use as per
the following guidelines:
WARNING:
It is mandatory that a Competent Person other than the user must perform a formal inspection of
the PFAS and its components at least once annually. This frequency should be altered on the basis of conditions
for use or exposure. The inspection results should be recorded in the inspection and maintenance log at the end
of this manual.
STEP 1:
Locate the impact indicators. The stitched impact
indicator is the section of the webbing that is folded
back into itself and held in place with a specific stitch
pattern. This stitch opens up releasing the warning sign
on the unfolded webbing when the harness is subjected
to a fall. If an impact indicator is found to have been
released, then the harness should be immediately
removed from service. (Fig. 1)
STEP 2:
Check the stitches on the harness. They should be intact,
no cuts, severe abrasion or visual damage
STEP 3:
Check the webbing by holding it with your hands 6 to 8
inches apart and bending the webbing in an inverted U.
By doing it this way, any damaged fibers or cuts can be
easily detected. Repeat this process for the entire length
of the webbing, checking both sides of each strap. Look
out for any frayed edges, broken fibers, cuts, burns,
pulled stitches and chemical damage. (Fig.3)
STEP 4:
Check the D-rings for sharp edges, distortion, cracks,
breaks, and rough edges. Look out for any broken
stitching of the D-ring attachments. Also, ensure the
D-ring pivots freely. (Fig.4)
STEP 5:
Inspect the pads for any cracks, excessive wear and
other signs of damage.
STEP 6:
Check the buckle attachments for abrasion, rust or
cracks. Check all connections to the webbing for
unusual wear, frayed or cut fibers, or broken stitching.
STEP 7:
Check the tongue buckles and grommets. The buckle
tongues should not be distorted in shape and motion.
They should overlap the buckle frames and freely move
in their sockets. Also, the roller should turn freely on
the frame. Look for any distortion or sharp edges. The
grommets should not be loose, distorted or broken.
Also, there should not be any additional punched holes
in the webbing.(Fig.7)
STEP 8:
Friction buckles should be inspected for distortion. The
center and outer bars of the buckle should be straight.
Carefully inspect the corners and attachment points at
the center bar.(Fig.8)
STEP 9:
If your harness has a quick connect buckle at the chest
it should be inspected for distortion, cracks and breaks.
The buckles should engage properly and function
smoothly.(Fig.7)
