Straightening Your Harness:
Pick up your harness by the Dorsal D-ring and shake it to allow the straps to fall free of each other.
Disconnect the waist strap of the harness and then disconnect the leg strap buckles. Hold the harness with one shoulder strap
in each hand to check for twisted straps. Straighten any twisted straps so that they hang freely.
Harness Inspection:
Inspection should occur prior to each use by the user and at a minimum of once a year by a competent person. Carefully inspect
the harness for indications of wear, deterioration, or impact loading. The inspection should include, but not be limited to,
inspecting for:
•webbing cuts, kinks, abrasions, burns, excessive swelling, excessive wear, discoloration, cracks, charring, broken fibers,
loose stitching, chemical or physical exposures and buckle holes in strap are not damaged
•loose, bent or pulled rivets, bent grommets, and broken, cut or burned threads
•tongue of buckle does not bind on buckle frame
•nicks, cracks, distortion, excessive wear or corrosion of hardware (buckle, "D"-ring, etc.)
Note: Buckingham harnesses are equipped with an impact load indicator label that is designed to deploy upon arresting a fall.
An impact load will tear the thread exposing this label making the text visible. If you can see the text, the harness has been
impact loaded. If any evidence of wear, deterioration, or impact loading as outlined is observed, immediately cease use, destroy
the product, and replace it with new equipment.

loop fastener together to secure (Fig. 41 –42).
Additional Instructions / Warnings for Quick Connect Buckle
For your information and attention:
Quick Connect Buckles on those Full Body Harnesses (FBH) and Arborist’s Tree Saddles that include this style of buckle may
unintentionally disengage under the condition outlined below:
If the pawls of the buckle do not freely rotate, proper engagement of the tab end to the receptor end of the buckle will be
hindered / restricted. If as a result of the user’s movements or through contact with an obstruction during the course of his/her

work, one of the two pawls of the receptor end of the buckle is depressed while tension is induced on the strapping attached to
the buckle, the potential exists that disengagement of the tab end of that side from the pawl may occur. If that position is
maintained and again through the user’s movements or contact with an obstruction the opposite side pawl is depressed, the tab
end of the buckle may totally disengage from the receptor end.
To eliminate the potential for this condition, you the user should:
1. Inspect your equipment before each use as you would for all safety equipment. Equipment should be
replaced if you have any question / doubt about it being safe for use.
2. Always position the buckles of your equipment so that contact with obstructions is avoided.
3. Test the pawls on your Quick Connect Buckles to ensure they freely rotate and return to their original
position. If any pawl does not freely rotate, the buckle should be (a) cleaned as outlined below to ensure
there are no obstructions inside the buckle hindering its intended function and (b) lubricated with a lightweight
lubricant such as WD-40® as recommended for locking snaphooks. If the pawl still does not freely rotate,
you should contact Buckingham Mfg. at the telephone number outlined below and request a Returned Goods
Authorization Number for immediate return of your harness or Arborists tree saddle for our inspection and/or
buckle replacement.
4. Ensure the receptor end and tab end of the Quick Connect Buckle is fully connected with both locking pawls engaged.
When the two halves are properly attached together, a clicking sound should be heard. Complete by pulling the adjuster
strap through the buckle and tighten until it is snug but comfortable, thus ensuring complete engagement.
Buckingham's primary concern is to provide a quality product to its customers to enable them to carry out their profession in a
safe manner. However, we always require our customer’s assistance in proper equipment operation, inspection and
maintenance.
INSTRUCTIONS / WARNING
Full Body Harnesses (FBH)
Manufacturer’s instructions shall be provided to the user of this product. If additional copy is needed, contact Buckingham Mfg. Co.
Read carefully, understand and heed these and all instructions, warnings and cautions as well as the ANSI Z359 “General
Requirements and Information” provided in the included Annex “A” and packaged with this product before using this equipment.
Failure to do so could result in your serious injury or death. Employer –instruct employee as to the proper use, warnings and
cautions before use of this equipment.
ANSI Z359.11, ASTM F887 and applicable OSHA regulations are standards / regulations utilized by Buckingham Manufacturing
Co. for various full body harnesses (FBH) manufactured. Harnesses are labeled to these standards as they are applicable.
Buckingham harnesses are intended as personal protection equipment for use by properly trained professionals
only. Each piece of equipment is important in its function and design and in its relationship to all other
components. Energy absorbing lanyards should be considered as a part of a personal fall arrest system used in
conjunction with a harness. The energy absorber (pack end) must always be attached to the fall arrest
attachment device included on the user’s equipment. Cover of energy absorber should not be removed and
will not have any effect on the shock absorbing feature. Harnesses must be worn so the fall arrest
attachment is centered in back near shoulder blade level. It is recommended that:
•A connecting device and fall arrest attachment manufactured with a web loop be attached with a hitch
(See detail), or carabiner.
•If using a locking snap hook to a web loop fall arrest attachment the web loop must be protected by an integral wear piece
to enhance visual inspection.
•All Web loop fall arrest attachments must be inspected before each use. The inspection should include, but not be limited
to, inspecting for: webbing cuts, kinks, abrasions, burns, excessive swelling, excessive wear, discoloration, charring,
broken fibers, loose stitching and chemical or physical exposures.
Note: The use of a locking snaphook to a web loop fall arrest attachment without an integral wear piece is acceptable in
emergency situations (i.e. rescue, evacuation, etc.) Attachment of a locking snap hook to a web loop fall arrest attachment with
no wear piece can cause premature wear of the webbing and stitching. This degradation can cause the web loop layers to
separate and be incapable of supporting your weight. Therefore, the web loop fall arrest attachment must be inspected before
use. Additionally, connections used to attach to the fall arrest attachment must have a minimum gate rating of 3600 lbf. and
meet ANSI Z359.12 requirements.
OSHA requires that impact force in a fall not exceed an 1800 lbf. limit with a harness. Proper use of a harness with an energy
absorbing lanyard will allow compliance with these limits when properly assembled.
Selection of products should be such that they aid the worker in the performance of his job and particular work situation. See
sections 10-16 of the included Annex “A” which provides additional information concerning the location and use of various
attachments that may be provided on the Full Body Harness (FBH). Therefore, be certain this equipment is suitable for the
intended use and work environment. It should only be used as personal protection equipment If suitability for intended use is
questionable, always consult your Supervisor, Safety Director or contact Buckingham Mfg. at [phone] or 1-800-937-2825.

P/N 230420
No fall protection system can guarantee that you will not sustain injuries should a fall occur. Therefore, lanyards should be kept as
short as possible to minimize free fall distance. OSHA specifies that maximum length of lanyard shall provide for a fall of no
greater than six (6) feet. In addition, other factors such as harness stretch not to exceed 18", D-ring / connector length, settling of
the user's body, lanyard length, including energy absorber extension and all other contributing elements should be such that the
user can not fall a distance that will allow contact with any lower level. The lanyard attachment point on the user should be in the
middle of the back near shoulder blade level. Do not lengthen a lanyard by tying or knotting to another lanyard or connecting a
snap to a snap. Lanyards should not be shortened by knotting rope or webbing as this can reduce the strength by 50% or more.
NOTE: The hitch detailed above is not considered a knot.
Do not alter your harness or any safety product in any way. If your harness does not fit properly, replace it with one of the correct
size. Wear your harness snug but not tight.
Unless the snap hook is a locking type with minimum gate rating of 3600 lbf., meets ANSI Z359.12 requirements, and designed for
the following connections, snap hooks shall not be engaged:
•directly to webbing, rope or wire rope
•to each other - they are not intended to be used that way and could twist apart
•to a D-ring to which another snap hook or other connector is attached.
•to a horizontal lifeline
•to any object which is incompatibly shaped or dimensioned in relation to the snap
hook such that the connected object could depress the snap hook keeper a
sufficient amount to cause it to release. (See Illustration)
Thorough employee training in the selection and proper use of personal protection equipment is imperative.
CAUTION
•Although ANSI Z359.11 recognizes the use of this harness only within the capacity range of 130 - 310 lbs. Buckingham harnesses, when
marked, can be used by a person with a maximum weight of 350 lbs when fully equipped. Additionally, Buckingham harnesses only can
be used by a person with a maximum weight of 420 lbs. when fully equipped and only when used with an equivalently weight rated
energy absorbing lanyard / accessories. Note: This maximum weight does not apply to body belts attached to a harness.
•Fall protection equipment, (i.e. fall arrest, work positioning belts, retrieval, suspension etc.) should not be resold or provided to others for
re-use after use by original user as assurance cannot be granted that a used product meets criteria of applicable standards and is safe
for use to a subsequent user.
•Only Buckingham Mfg. Co. or those people authorized in writing by Buckingham Mfg. Co. may make repairs to this equipment.
•Equipment subjected to impact loading must be immediately removed from service, destroyed and discarded.
•In the event of a fall, the employer must have a rescue plan and the means to implement it.
•Attach only locking connecting devices meeting standards / regulations for intended use for fall arrest, positioning and suspension to rear
fall arrest D-ring on harness and fall arrest anchor point, saddle / belt D-rings and attachment points.
•Only positioning connecting devices should be attached to side D-rings, as side D-rings are not intended for fall arrest.
•Do not connect any tools, accessory loops / snaps, etc. to the positioning D-rings. D-rings are for attachment of connecting device locking
snap hooks only.
•For units with Work Position Web Loop(s): Buckingham recommends attachment only to carabiner. Buckingham Mfg. does not
recommend attachment of a metal connector, other than a carabiner, to a web loop fall arrest attachment unless the web loop is
protected by an integral wear piece, the connector meets the requirements of ANSI Z359.12 (3600 lbf. rated gate), the snap hook lock
mechanism cannot inadvertently be depressed, and the web loop fall arrest attachment point is inspected prior to each use. Attachment
of a metal connector, such as a locking snap hook, to a web loop fall arrest attachment with no wear piece can cause premature wear of
the webbing and stitching. This degradation can cause the web loop layers to separate and be incapable of supporting your weight.
•If connecting to a personal fall arrest system by attaching directly through the web loop of an energy absorber carefully inspect the inside
of the web loop for cuts, abrasions, broken strands, or excessive wear.
•Buckingham harnesses are manufactured with a breakaway lanyard parking attachment that is generally located in the sternal area of
the harness. This lanyard parking attachment is designed only to store unused lanyard legs to help reduce tripping and entanglement
hazards. Lanyard parking attachments are designed to breakaway at no more than 120 lbf. and are not to be used as load bearing
anchor points.
•Fall arrest anchor points must support a minimum of 5000 lbf. per attached worker and be independent of worker support.
•For fall arrest, always keep anchor point above rear fall arrest attachment. If climbing above anchor point, attach to a new anchor point
higher up. When anchor point to allow for connection above the fall arrest attachment device is not available, lanyard positioning must
be such that free fall will be limited to a maximum of 6 feet and there will be no contact with a lower level.
•Never use an energy absorbing lanyard for positioning. Unit can open and extend which could result in a fall.
•Always attach the energy absorbing lanyard to the rear fall arrest attachment device included on the user’s equipment.
•Always visually check that: 1) each snap hook / carabiner freely engages D-ring or anchor point, 2) keeper / gate is completely closed
with each use. Never rely solely on the feel or sound of a snap hook / carabiner engaging.
•Make sure each snap hook / carabiner is positioned so that its keeper / gate is never load bearing.
•Never use combinations of components or sub systems, or both, which may affect or interfere with the safe function of each other.
•Ensure there is no pressure on the snap hook locking mechanism sufficient to depress it as this will, due to its length, render it
incompatible with currently designed rings and make it very susceptible to rollout.
•Never disable locking keeper / gate on snap hook / carabiner, punch holes in or alter a connecting device in any way.
•Avoid contact of this equipment with sharp edges, abrasive surfaces, high temperature surfaces, welding, or other heat sources,
electrical hazards or moving machinery. When not in use, store to prevent exposure to the elements as well as over exposure to sunlight
(U.V. degradation).

•Avoid contact of this equipment with chemicals that may damage the material. If in doubt, contact Buckingham Mfg. Co.
•This equipment is for personal use only, not towing or hoisting.
•Never work without independent fall arrest protection if there is danger of a fall.
•Always visually check that all buckles and snap hooks or carabiners are properly closed before use.
•Shoulder D-rings / attachments (optional) are intended for rescue / retrieval purposes only.
•Product covered under these instructions / warnings should not be resold / redistributed or re-used after use by original user
INSPECTION
Inspection should occur prior to each use of the harness by the user and at a minimum of once a year by a competent
person. Carefully inspect the harness for indications of wear, deterioration or impact loading. The inspection should
include, but not be limited to, inspecting for:
•product with all leather strength components. If found, immediately cease use, discard and replace as product does not meet existing
standards
•webbing cuts, kinks, abrasions, burns, excessive swelling, excessive wear, discoloration, cracks, charring, broken fibers, loose stitching,
chemical or physical exposures and buckle holes in strap are not damaged
•loose, bent or pulled rivets, bent grommets, and broken, cut or burned threads
•tongue of buckle does not bind on buckle frame
•nicks, cracks, distortion, excessive wear or corrosion of hardware (buckle, "D"-ring, etc.)
•check hook and loop fastener chest strap closure by adhering the hook and loop fastener securely together. When removing the hook
from the loop, if there is little or no resistance, cease use and replace immediately. Hook and loop fastener will require a notable force to
separate.
NOTES: Buckingham harnesses are equipped with an impact load indicator label that is designed to deploy upon arresting a fall.
An impact load will tear the thread exposing this label making the text legible. If you can read the text the harness has
been impact loaded. If any evidence of wear, deterioration or impact loading as outlined is observed, immediately cease
use, destroy the product and replace it with new equipment. Should any unusual conditions not outlined above be
observed, or you have reasonable doubt about a particular condition, remove the equipment from service and notify
your Supervisor, Safety Director or contact Buckingham Mfg. for clarification. Failure to carefully and completely inspect
your equipment could result in serious injury or death.
Maintenance
•Proper maintenance and storage of your equipment will prolong its useful life and contribute toward its performance.
•Nylon and polyester webbing should be cleaned with water and mild soap (a dish washing soap that removes grease (i.e. Dawn))
and be allowed to dry thoroughly without using excessive heat.
•Hook and loop fastener of the chest strap closure is completely washable using the method described for nylon and polyester
webbing. Additionally, it is dry cleanable. For best results mate fasteners before laundering or dry cleaning.
•The Quick Connect Buckle may be cleaned by using a cotton swab, limited air pressure or dipping it into a container of water to
remove fine particles and any foreign matter which may enter the receptor end of the buckle and preventing proper engagement
and function. The exterior of the buckle should be dried with a clean cloth. The inside of the receptor end of the buckle should be
air-dried and re-lubricated.
•Additionally, the Quick Connect Buckle pawls should be lubricated weekly or as often as required to maintain smooth operation (no
binding) with a lightweight lubricant such as WD-40®. Wipe any excess lubricant off with a clean dry cloth.
Rust on Harness Hardware
If through regular product inspection you note rust on hardware, the severity of the rust will determine whether the harness is deemed
usable or unacceptable and recommended for removal from service. Below are examples of hardware rust exposure deemed
acceptable for keeping the harness in service or unacceptable and recommended to cease use.
Slight/Moderate (Acceptable): White Scale / Oxidation and Surface Rust
Single Slot 2 Slot QC buckle
Slight Slight Moderate
Buckingham recommends cleaning hardware in this condition using an ultrafine Scotch Brite scouring pad (3M part number 14049
available at distributors such as Grainger), cut to approximately a 1” x 1” square, and with WD-40 Multi-Use Product or Hilco Lube
lubricant cleaner (also available at retail distributors such as Grainger), scrub the areas that exhibit rust in a back and forth motion
until all surface rust has been removed.

2. Correct fit of a Full Body Harness is essential to proper performance. Users must be trained to select the size and maintain the fit of
their Full Body Harness.

3. Users must follow manufacturer’s instructions for proper fit and sizing, paying particular attention to ensure that buckles are
connected and aligned correctly, leg straps and shoulder straps are kept snug at all times, chest straps are located in the middle chest
area, and leg straps are positioned and snug to avoid contact with the genitalia should a fall occur.
4. Full Body Harnesses which meet ANSI/ASSE Z359.11 are intended to be used with other components of a Personal Fall Arrest
system that limit maximum arrest forces to 1800 pounds (8 kN) or less.
5. Suspension intolerance, also called suspension trauma or orthostatic intolerance, is a serious condition that can be controlled with
good harness design, prompt rescue, and post fall suspension relief devices. A conscious user may deploy a suspension relief device
allowing the user to remove tension from around the legs, freeing blood flow, which can delay the onset of suspension intolerance. An
attachment element extender is not intended to be attached directly to an anchorage or anchorage connector for fall arrest. An energy
absorber must be used to limit maximum arrest forces to 1800 pounds (8 kN). The length of the attachment element extender may
affect free fall distances and free fall clearance calculations.
6. Full Body Harness (FBH) Stretch, the amount the FBH component of a Personal Fall Arrest system will stretch and deform during a
fall, can contribute to the overall elongation of the system in stopping a fall. It is important to include the increase in fall distance created
by FBH Stretch, as well as the FBH connector length, the settling of the user’s body in the FBH, and all other contributing factors when
calculating total clearance required for a particular fall arrest system.
7. When not in use, unused lanyard legs that are still attached to a Full Body Harness D-ring should not be attached to a work
positioning element or any other structural element on the Full Body Harness unless deemed acceptable by the competent person and
manufacturer of the lanyard. This is especially important when using some types of “Y” style lanyards, as some load may be
transmitted to the user through the unused lanyard leg if it is not able to release from the harness. The lanyard parking attachment is
generally located in the sternal area to help reduce tripping and entanglement hazards.
8. Loose ends of straps can get caught in machinery or cause accidental disengagement of an adjuster. All Full Body Harnesses shall
include keepers or other components which serve to control the loose ends of straps.
9. Due to the nature of soft loop connections, it is recommended that soft loop attachments only be used to connect with other soft
loops or carabiners. Snap hooks should not be used unless approved for the application by the manufacturer.
Sections 10-16 provide additional information concerning the location and use of various attachments that may be provided
on this FBH.
10. Dorsal –The dorsal attachment element shall be used as the primary fall arrest attachment, unless the application allows 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
around 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 allow a more vertical rest
position post fall, but can increase FBH Stretch.
11. Sternal –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.
Accepted practical uses for a sternal attachment include, but are not limited to, ladder climbing with a guided type fall arrestor, 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. Supporting 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 the user during a fall,
extraction, suspension, etc. The competent person should consider Full Body Harness models with a fixed sternal attachment for these
applications.
12. Frontal –The frontal attachment serves as a ladder climbing connection for guided type fall arrestors where there is no chance to
fall in a direction other than feet first or may be used for work positioning. Supporting the user, post fall or during work positioning, by
the frontal attachment will result in a sitting body position, with the upper torso upright, with weight concentrated on the thighs and
buttocks. When supported by the frontal attachment the design of the Full Body Harness shall direct load directly around the thighs and
under the buttocks by means of the sub-pelvic strap.
If the frontal 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.
13. Shoulder –The shoulder attachment elements shall be used as a pair, and are an acceptable attachment for rescue, and
entry/retrieval. The shoulder attachment elements shall not be used for fall arrest. It is recommended that the shoulder attachment
elements be used in conjunction with a yoke which incorporates a spreader element to keep the Full Body Harness shoulder straps
separate.

14. Waist, Rear –The waist, rear attachment shall be used solely for travel restraint. The waist, rear attachment element shall not be
used for fall arrest. Under no circumstances is it acceptable to use the waist, rear attachment for purposes other than travel restraint.
The waist, rear attachment shall only be subjected to minimal loading through the waist of the user and shall never be used to support
the full weight of the user.
15. Hip –The hip attachment elements shall be used as a pair and shall be used solely for work positioning. The hip attachment
elements shall not be used for fall arrest. Hip attachments are often used for work positioning by arborists, utility workers climbing
poles, and construction workers tying rebar and climbing on form walls. Users are cautioned against using the hip attachment elements
(or any other rigid point on the Full Body Harness) to store the unused end of a fall arrest lanyard, as this may cause a tripping hazard,
or, in the case multiple leg lanyards, could cause adverse loading to the Full Body Harness and the wearer through the unused portion
of the lanyard.
16. Suspension seat - The suspension seat attachment elements shall be used as a pair and shall be used solely for work positioning.
The suspension seat attachment elements shall not be used for fall arrest. Suspension seat attachments are often used for prolonged
work activities where the user is suspended, allowing the user to sit on the suspension seat formed between the two attachment
elements. An example of this use would be window washers on large buildings.
