SAFETY SUMMARY
1 GENERAL SAFETY INSTRUCTIONS.
This manual describes physical and/or chemical processes which may cause injury or death to personnel, or damage to
equipment, if not properly followed. This safety summary includes general safety precautions and instructions that must be
understood and applied during operation and maintenance to ensure personnel safety and protection of equipment. Prior to
performing any specific task, the WARNINGs, CAUTIONs, and NOTEs included in that task shall be reviewed and under-
stood.
2 WARNINGS, CAUTIONS, AND NOTES.
WARNINGs and CAUTIONs are used in this manual to highlight operating or maintenance procedures, practices, condi-
tions, or statements which are considered essential to protection of personnel (WARNING) or equipment (CAUTION).
WARNINGs and CAUTIONs immediately precede the step or procedure to which they apply. WARNINGs and CAUTIONs
consist of four parts: heading (WARNING, CAUTION, or icon), a statement of the hazard, minimum precautions, and
possible results if disregarded. NOTEs are used in this manual to highlight operating or maintenance procedures, practices,
conditions, or statements which are not essential to protection of personnel or equipment. NOTEs may precede or follow the
step or procedure, depending upon the information to be highlighted. The headings used and their definitions are as follows:
Highlights an essential operating or maintenance procedure, practice, condition, statement, etc., which if not
strictly observed, could result in injury to, or death of, personnel or long term health hazards.
Highlights an essential operating or maintenance procedure, practice, condition, statement, etc., which if not
strictly observed, could result in damage to, or destruction of, equipment or loss of mission effectiveness.
NOTE
Highlights an essential operating or maintenance procedure, condition, or statement.
3 SAFETY PRECAUTIONS.
The following are broad electronics maintenance safety precautions related, in general, to all of the maintenance and
operation procedures covered by this technical order (TO). These safety precautions may not necessarily appear again in this
TO, together with those procedures with which they apply. Maintenance personnel shall read, understand, and apply these
precautions during any applicable maintenance operation. In addition, operators should be thoroughly familiar with appli-
cable safety regulations as stated in AFI 91-301.
3.1 Keep Away From Live Circuits. Do not replace components or make adjustments inside the equipment with electrical
power present or hooked up. Also, under some conditions, dangerous hazards may exist with power turned off and power
source not hooked up. Hazardous electrical potentials may exist at such times because of electrical charges stored in
capacitor circuits. To avoid injuries, always unhook electrical power and then discharge and ground any circuit before
touching it. Follow all safety interlock requirements.
3.2 Do Not Service or Adjust Equipment While Alone. Do not attempt maintenance operations where shock potential
exists unless another person qualified to render first aid and resuscitation is present.
3.3 Resuscitation. Personnel working with or near dangerous voltages or hazardous materials must be qualified on
approved methods of resuscitation. For information on first aid or resuscitation, contact your supervisor or the Base Office of
Bioenvironmental Health.

CHAPTER 2
PROCEDURES FOR SAFETY BELTS, STRAPS, AND HARNESSES
2.1 GENERAL.
Industrial type safety belts, straps, harnesses, rescue slings, wrist harness, boatswain harness/chairs and miscellaneous belts
harness etc., shall be utilized for their intended purpose only. During use, care should be exercised to prevent them from
contact with moisture, hydraulic fluids, oil, grease, fuel, steam pipes, or other like heat sources. In the event they become
wet, they shall be dried without the aid of artificial heat, i.e., at room temperature. In the event oils and lubricants come in
contact with these, they shall be wiped and cleaned as soon as possible to prevent saturation and absorption. Typical straps
and harnesses are shown in Figure 2-1 and Figure 2-2. (Industrial safety belts are not shown.) While in service use the
equipment described in this chapter shall be visually inspected by utilizing personnel as outlined in following paragraphs.
Nylon belts shall not be used in areas where acid conditions exist. Polyester or polypropylene belts, harnesses, straps, etc.,
shall not be used where caustic conditions exist or in temperatures exceeding 180 degrees Fahrenheit (°F). Leather straps
shall not be used in temperature above 150 °F. Extra holes shall not be punched in this equipment.
2.2 STORAGE REQUIREMENTS.
Safety belts, straps, and harnesses will be stored in their original shipping containers when possible in a cool dry place until
they are issued or worn. When not in use they shall be stored in any well ventilated area supported on slats or hung in loose
coils. Do not store in areas where they could be subjected to mechanical or chemical damage. Where possible storage of
these items should be in a temperature range of 35 to 100 °F and out of direct sunlight. The term “dry” is usually used to
denote an area where condensation (moisture) does not come in contact with the containers or their contents. An example
would be storing the packages in a building away from its wall and in pallets. Periodic examinations of the storage
containers should be made more frequently when storage containers vary from the ideal. Therefore, if the belts, straps, and
harnesses are stored properly and meet the inspection requirements outlined they can be considered safe for day to day use.
Exception, when stored for use on aircraft, safety belts, straps, and harnesses will be stored in bag part number (PN)
5140004736256, or equivalent. All safety equipment will be dry when stored in this bag. All users will perform a thorough
inspection prior to use on all equipment before each use.
2.3 SHELF LIFE.
There is no chronological service life for this equipment. User should rely on a visual inspection of condition on a daily
basis and remove equipment from service when it shows excessive wear or deterioration.
2.4 TYPES OF INSPECTION.
Inspection of belts, straps, harnesses, etc., described in this chapter shall consist of the following types:
2.4.1 Initial Inspection. Before using new equipment, it shall be inspected to make sure that proper equipment is being
used for the function for which it was designed, possible manufacturers’ defects, and that it meets requirements of this
handbook.
2.4.2 User Inspection. This inspection shall be made by the person handling or using this equipment each time it is used.

• Missing, loose, broken, or distorted parts (except miscellaneous parts such as tape thongs, plier pouches, etc.).
• Abrasion marks resulting in rupture exceeding ten percent of width or one inch in length.
• Any hole, cut, or tear.
• Frayed edges or smashes.
• Excessive soiling.
NOTE
Excessive soiling is defined as any type of soiling that covers up the web fibers to the point that it prohibits the
user or inspector from inspecting for defects in accordance with the TO.
• Broken, worn, loose or missing rivets or stitching.
• Broken, cracked, or deformed D rings, snap hooks, plates, and buckles.
• Snap hook keeper latch bent, broken, or missing.

• Slippage of webbing through buckles and adjusters.
NOTE
Fraying, cuts, abrasions, etc., of the body pad portion of the belt, which is a nonstress or nonsupporting area, are
not considered critical. Any of cited defects which are directly related to the waist belt portion of the belt, which
is supporting and subject to stress, are considered critical and rejection shall be done accordingly.
• Absence of or illegible markings.
2.6 DEFECTS.
Belts, straps, harnesses, and life lines constructed of leather shall be inspected for the following defects, any one of which is
cause for rejection of the piece of equipment being inspected.

2.7 MARKING AND DISPOSITION.
Periodic inspection due dates will be affixed crossways on free ends of belts, harnesses, straps, etc., using black or white
stencil ink, Federal Specification AA-208B or equal. Black ink shall be used except where equipment is dark resulting in
poor legibility. A protective coating of clear lacquer, or lacquer acrylic, shall be applied over the date to protect it from wear.
Dates shall be recorded in chronological order. This abbreviation “Insp” followed by the word “due” and the date will be
marked to indicate the date next inspection is due. Example: INSP due JAN 2007. Each subsequent inspection due date will
appear below preceding date.
NOTE
A tag stamped or laser etched with the inspection due date as outlined in Paragraph 2.7 may be used in lieu of
stenciling the required inspection information on the piece of equipment. When using a tag, it must be attached to
the equipment with a lanyard. Tags/lanyards attached to equipment used on the flight line or in aircraft mainte-
nance areas must be securely attached in manner to preclude loss and potential Foreign Object Damage (FOD).
The tag/lanyard shall not impair operation of the item. Group commanders may direct use of an Air Force
Technical Order (AFTO) Form 244, industrial/Support Equipment Record; a locally developed form; or a com-
puter generated program to document inspections.
2.7.1 Unserviceable Belts, Harnesses, and Straps. Belts, harnesses, straps, etc., found to be unserviceable as result of
inspection will be tagged as condition condemned property. To prevent reuse, they shall be rendered useless by cutting
across webbing or straps.

2.8 CLEANING.
Leather belts, harnesses, straps, etc., will be cleaned approximately every 3 months and dressed approximately every 6
months while in service use. If leather units that are initially issued are found to be hard and dry they shall be inspected for
serviceability and dressed before use.
a. Wipe off all surface dirt with a sponge dampened (not wet) with water.
b. Rinse out sponge (or rag) in clear water and squeeze until practically dry. Then with aid of neutral soap (free from
alkali) such as castile or white toilet strap work up a thick lather and thoroughly wash the entire article to remove
embedded dirt and perspiration and then wipe with clean cloth to remove all moisture. Using a good grade of saddle
soap repeat above for leather items and allow to dry at room temperature.
c. To apply dressing do not allow to dry. While leather is still damp, use for each article about one-quarter ounce (2
teaspoons) of neat’s foot oil and apply the oil gradually with a wool rag using light strokes to work it into the leather.
After oiling, the article should be set aside in a dry, cool place for about 24 hours in order to permit the leather to dry
slightly and then wipe with a soft cloth to remove excess oil.
NOTE
Oil applied to dry or dirty leather has a harmful affect on leather. Clean as outlined before oiling and use only
neat’s foot oil.
d. Nylon articles may be cleaned by the same method as outlined for leather, only no dressing is required either with
saddle soap or neat’s foot oil.

CHAPTER 3
RESTRAINT ASSEMBLIES, SAFETY NETS, ESCAPE ROPES, LANYARDS,
AND LIFELINES
3.1 GENERAL.
Any lifeline, escape rope, or lanyard actually subjected to in service loading, exceeding that of the rated static load
testing, shall be immediately removed from service and shall not be used again for personnel safe guarding.
Failure to comply could result in damage to, or destruction of, equipment or loss of mission effectiveness.
Restraint assemblies, safety nets, escape ropes, lanyards, lifelines, Personal Fall Arrest System (PFAS) and their components
shall be used for their intended purpose only. The general requirements concerning storage data, daily use, shelf life, and
inspection requirements are the same for these items as for belts, straps, and harnesses; they shall be periodically inspected
every 90 days, and the inspection dates will be recorded on a tag affixed to the free end of each rope (see Paragraph 3.1.1
and Paragraph 3.2.2.1 for exceptions). Restraint assemblies, shock absorbers, and safety nets are shown in Figure 3-1, Figure
3-2, and Figure 3-3. In addition, fiber ropes should be stored in areas where not subjected to mechanical or chemical

3.2 ESCAPE ROPES, LANYARDS, AND LIFELINES.
NOTE
For those escape ropes which are locally fabricated, make sure date of manufacture is obtained from the bulk roll
from which the subject rope is taken. This date will be attached as directed in Paragraph 3.1 and will be consid-
ered the date of the initial periodic 90 days inspection.
3.2.1 Inspection. Escape ropes, lanyards, and lifelines shall be inspected every 90 days or any time their condition is
considered questionable. Inspect rope assemblies for the following defects, any one of which is basis for rejection.
• Any cut, chafe, or nicks.
• Bulged strands.
• Knots in individual strands.
• End fittings not properly attached (served, spliced, wrapped, etc.).
• Abnormal weakness detected visually.
• Powdered fibers between strands.
• Variation in size or roundness of strands.
• Discoloration or rotting.
• Broken, bent, or deformed fittings.
TO 00-25-245

• Surface corrosion on end fittings (reject only when pitted).
3.2.2 Ropes.
Fiber ropes shall not be used for support of humans around welding, burning, or other heat producing sources.
Failure to comply could result in damage to, or destruction of, equipment or loss of mission effectiveness.
Block assembly, single sheave used in missile silos contains many rope or polypropylene rope (national stock number (NSN)
4220-00-874-7921SX). Inspect the rope as outlined in Paragraph 3.2.1. Inspect the sheave for pulley movement, deformity,
cracks, missing components, and surface corrosion. (Reject if pitted.)
3.2.2.1 Escape Ropes Used on Aircraft. Escape ropes installed on aircraft as part of the aircraft egress system are
excluded from the 90 days inspection. See applicable aircraft technical order for specific instructions.
3.3 SAFETY NETS.
The general requirements, types of inspection, storage data, and shelf life for safety nets are the same as for belts, straps, and
harnesses. Since most all safety nets are constructed of ropes, cords, webbing, snaps, etc., inspection procedures and defects
for rejection are basically the same. Therefore, all types of safety nets (as found in FSC 4240) shall be inspected as
indicated. Inspect the net and shock mechanism for the following defects any one of which is basis for rejection.
• Damaged or parted ropes or webs.
• Parted segments.
• Snaps and D rings for physical damage (broken, cracked, deformed, or keeper latch missing).
• Surface corrosion (reject only when pitted).
Figure 3-1. Restraint Kit Assembly

• By touch and sight, inspect all butyle rubber for swelling, discoloration, lamination separation, tears, cracking, or
any other abnormalities.
• Straps and ropes as previously outlined.
3.4 RESTRAINT ASSEMBLIES.
Restraint assemblies outlined herein pertain to those assemblies used by ground personnel working on horizontal stabilizers,
wings, fuselage, and empennage of C-135, C-17 and C-5 aircraft. The storage data, shelf life, types of inspection, and
general requirements for these items are the same as for belts, straps, ropes, and harnesses. Shock absorbers utilized with this
type of equipment are covered separately in subsequent paragraphs. Restraint assemblies described herein shall be periodi-
cally inspected every 90 days. Except where indicated any one defect is basis for rejection. Inspect for following:
• Abnormal deflection of rope assembly. (Also see rope inspections.)
• Parted segments of rope assembly.
• Broken, cut, or chafed ropes.
• Mildew, fungus, or mold on rope assembly.
• Deformed, cracked, or permanent set in the anchoring eyes.
• Surface corrosion (reject only when deeply pitted).
• Inspect harnesses per procedures for belts, straps, and harnesses.
• Bolt assemblies for deformity, cracks, or permanent set.
• For C-5 restraint assembly also see technical order (TO) 1C-5A-2-2.
3.5 SHOCK ABSORBERS.
Generally the storage and general requirements for shock absorbers are the same as those outlined for belts, straps, and
harnesses. Personnel utilizing these absorbers will note any unusual signs of wear during inspections prior to and after use.
When signs of wear are evident or at a minimum of every 2 years, shock absorbers shall be inspected for defects as outlined
for snaps, D rings, nylon, belts, straps, and harnesses. In addition, they shall be inspected for separation of nylon filaments
from straps. Separation is basis for rejection. Shock absorbers do not lend themselves to nondestructive tests. Energy is
absorbed by the breaking of nylon filaments which bind the nylon strap and any pull test would render them unserviceable.
If they are properly stored and visually inspected every 90 days, they can be considered safe for day to day use. Minor holes,
cuts, tears, or loose stitchings in the protective covering of the shock absorber are not causes for rejection provided the nylon
strap and its filament are not affected. Such defects should be covered with tape to prevent contamination of nylon filaments.

5.5 RESCUE STROP AND CABLE WEIGHT COVER.
5.5.1 General. The Strop (also known as the Horse-Collar Quick Strop and Rescue Strop) is used to assist personnel
performing personnel recovery from a helicopter over water or land. The strop accommodates one survivor at a time. Refer
to Life Saving Systems web site for most recent part numbers: www.lifesavingsystems.com.
5.5.2 Configuration. The Rescue Strop is a buoyant device made of a closed-cell foam filling encased in an international
orange cover for high visibility during rescue operations. Webbing weaved through the cover with both ends terminating in
two V-rings, is used to attach the strop to the helicopter rescue hook. A 5000 pound locking carabiner may be used to
facilitate the connection to the hoist hook. Two retainer straps, one with a gated snap hook and one with an adjustable curved
V-ring are fastened to the strop with the hardware ends secured with webbing keepers (Figure 5-3, Figure 5-4, and Figure
5-5). The Cable Weight Cover is a bright yellow, waterproof, buoyant cover encasing a foam rubber filling. The cover has
four snap fasteners and a tie cord that keep the cover secure around the cable weight (Figure 5-6).
5.5.3 Application. The Rescue Strop and Cable Weight Cover are intended for use by personnel performing helicopter
personnel recovery operations when it is impossible for the helicopter to make a landing on land or water. The strop can be
used to lower a rescuer, as well as to raise a survivor to the helicopter. The strop is intended for the rescue of conscious
survivors. Use of the Rescue Strop to rescue unconscious survivors is authorized only in an emergency situation when
MEDEVAC Litter is not available and the Rescue Strop has been modified to prevent accidental patient release.
5.5.4 Function.
Failure to properly use the retaining straps on the Rescue Strop may allow the survivor to slip and fall from the
strop.
The Rescue Strop is lowered on a hoist cable from a helicopter to the survivor to facilitate rescue procedures. The Cable
Weight Cover protects the survivor from serious injury if the survivor is accidentally hit with the cable weight. Sling Rescue
Strop from hoist with retaining straps on the outside. Strop is positioned around survivor’s chest with survivor facing hoist
and arms on top to either side. Pass straps over the top of the survivor’s arms, then route straps from arms down and under
strop and connect the two strap ends across survivor’s chest. Tighten adjustable strap tension to hold survivor’s arms firmly.

5.8.1 General. The Rope Ladder is used to assist personnel performing personnel recovery from a helicopter over water
or land. Current approved ladders for helicopter use are manufactured by Randon Tech Manufacturing. [email protected].
5.8.2 Configuration.
5.8.2.1 HH-60 and H-1 Helicopters. The Rope Ladders (HH-60 ELD800PD, floor mounted), (IIH-60 ELD800PD-60,
ceiling mounted) and (H-1 ELPD800PD-1, floor mounted) are made of nylon fabric attaching aluminum rungs to form a 25
foot ladder assembly. The ladder assembly is attached to the ladder detacher mechanism. The detacher mechanism is
installed to the aircraft cargo/rappel rings via two 5000 pound carabiner, depending on ladder type.
5.8.2.2 MH-53 Helicopters.
The ELD series are not designed to be employed on the MH-53. Serious injury to personnel could result.
The Rope Ladder (TCL600) is made of stainless steel and aluminum materials forming a 60 foot ladder assembly with 12
inch rung spacing. This ladder is used on MH-53 series helicopters. The cable Rope Ladder is attached to the aircraft floor
using cargo restraining straps or the Universal Ladder Detacher assembly.
5.8.3 Application. The Rope Ladder is intended for use by personnel performing helicopter personnel recovery operations
when it is impossible for the helicopter to make a landing on land or water. The ladder is used to recover personnel into the
helicopter. The Rope Ladder can accommodate three personnel climbing at a time.

5.8.4 Function.
This “short haul” usage is for emergency situations when risk to the team is greater than the risk of the ladder
failing (e.g. under fire, during shark attack, fuel spill etc.). Failure to comply could result in injury to, or death of,
personnel or long term health hazards.
The Rope Ladder is configured to the aircraft cabin floor using two 5000 pound locking carabiner or cargo restraining straps
attached to the cargo floor rings or to the overhead rappel rings depending on ladder model/series. From a low hover the
ladder can be lowered to the ground allowing ground personnel to climb the ladder and recover themselves into the
helicopter. The ELD800PD series was not designed to ferry personnel (short haul) while suspended during forward/rearward
flight.
5.9 MAINTENANCE OF ROPE LADDER (HH-60 ELD800PD SERIES).
5.9.1 General. The following inspection and care criteria were developed with Randon Tech Manufacturing. These
criteria will be used to inspect and care for all Randon Tech HH-60 ELD800PD (floor mounted), HH-60 ELD800PD-60
(ceiling mounted) and H-1 ELPD800PD-1 (floor mounted) Rope Ladders.
5.9.1.1 Service Life Expectancy. The service life begins for new ladders the date the ladder is removed from the scaled
package. The effective service life of a Rope Ladder to be used for live operations is 6 years. New ladders will be sent for
full refurbishment at 3 years from initial service life date (receive an off-white serial tracking tag). Refurbished ladders will
be used 3 years from the date removed from the sealed package (receive a red serial tracking tag). Ladders meeting second
3 year mark will either be condemned or used for non-live training (top and bottom rungs painted yellow).
5.9.2 Inspection. All Randon Tech Rope Ladders in the ELD800PD series shall be subjected to a 3 year manufacture
refurbishment inspection. Ladders already in service will have a serial number tracking tag installed at this time. New
ladders should issue with tracking tag already installed. After the 3 year cycle ladders need to be removed from service and
sent to manufacture for refurbishment and inspection. Once refurbishment is complete the ladder may be used an additional
3 years. The life cycle of the ladder will not exceed 6 years of service life. After completing 6 years of service the ladder will
be marked “Training Use Only”, used for non-live training (top and bottom rungs painted yellow), or discarded. All
maintenance actions or inspections shall be recorded on appropriate form.
5.9.3 Live Use Preflight Inspection.
• If any nicks or excessive fraying to the point of broken strands are found, do not use the Rope Ladder for live
operations, serious injury or death may result. See Figure 5-7 and Figure 5-8.
• The following indicate obsolete equipment and should not be used for live operations; serious injury or death
may result:
• Corrosion on the rivet-washer connection points (should be stainless-stainless).
• Rope Ladder fabric with shiny appearance (similar to a vehicle seat belt).
• Detacher housings without beveled or rounded edges.
TO 00-25-245
5-12
• When preparing the Rope Ladder for night operations do not use duct tape on the nylon fabric. Duct tape
residue hinders the post flight fabric cleansing, and hides potential problem areas (e.g. use rubber bands, plastic
zip ties). Failure to comply could result in damage to, or destruction of, equipment or loss of mission effec-
tiveness.
• During inspection, dragging the Rope Ladder on concrete should be kept to a minimum to reduce abrasion and
maintain normal service life.
a. Ensure detacher serial numbers match Rope Ladder.
b. Inspect detacher device fasteners for loosening and failure.
c. Inspect detacher pip pin for proper spring/operation.
d. Inspect carabiners for corrosion and proper operation.
e. Inspect wheeled rungs and fasteners for loosening and failure.
f. Inspect main ladder straps for dry-rot, holes, nicks and excessive fraying. See Figure 5-7, Figure 5-8 and Figure 5-9.
NOTE
• Ensure both sides of the Rope Ladder are visually inspected.
• Detachers are “powder-coated”, there is no need to oil parts.
• Small amounts of hydraulic fluid are allowed on the fabric.
• Ensure the ladder is cleaned after use.
g. Inspect ladder rungs for damaged tubes or grip tape.
h. Inspect rung rivet-washer points for corrosion, cracks or stretched fabric.
i. Ensure no twists exist with main ladder straps.
j. Fold or roll the ladder into the stowed position on the cabin floor.

5.9.4 Rope Ladder Post-Flight and Cleaning.
• To maintain the usable life of the live-use Rope Ladder, thoroughly clean the ladder and detacher after every
salt water use, when contaminated with oils/hydraulic fluid and when heavily soiled after over-land use. Failure
to clean salt and encrusted dirt will decrease Rope Ladder service life.
• Rope Ladders should be stored in a dry environment, protected from prolonged, direct sunlight and fluorescent
lights. These conditions decrease the Rope Ladder service life.
• When washing, use a non-chlorinated alkaline detergent using mixture ratios prescribed on the detergent. Do
not use bleaches or chlorine products as they degrade the fabric fibers and their elasticity and decrease Rope
Ladder service life.
a. Carefully remove chem-lights from ladder rungs as required.
b. Separate detacher from ladder and insert into soap solution.
c. Place detacher in rinse container then set out to dry.
d. Place ladder in soap solution container and allow soaking for thirty minutes.

Use a fresh water container or an open hose to rinse Rope Ladder. High pressure washers will damage Rope
Ladder fabric and decrease service life. Failure to comply could result in damage to, or destruction of, equipment
or loss of mission effectiveness.
e. Move ladder through rinse container until visibly free from soap.
f. Attach ladder to detacher (check matching serial numbers).
g. Lay system horizontally (flat) to dry. Do not hang Rope Ladder to dry.
h. Once dry, place in carrying bag/harness and store on “live-use” rack.
5.9.5 Repairs. Maintenance of the Rope Ladder Assembly is limited to inspection and cleaning. Ladders requiring repair
will be sent to manufacturer for refurbishment.
5.9.6 Storage Requirements. Ladder fabric deteriorates at a greater rate under certain conditions decreasing service life.
Ladders should be stored out of extensive direct sunlight and fluorescent light. Ladders should be kept in a climate con-
trolled low-humidity environment. When ladders are not in use they should be stored in the ladder carrying case.
5.10 MAINTENANCE OF ROPE LADDER (TCL600).
5.10.1 Live Use Preflight Inspection.
NOTE
A ladder which does not fulfill any of the inspection criteria must be withdrawn immediately from active use.
a. Inspect entire length of ladder for fraying of the braided cable.
b. Inspect entire length of ladder for any corrosion.
c. Note any kinks in the cable and inspect closely for wire separation.
d. Lay out entire ladder and inspect for proper rung location. A loosened rung positioning swedge button will be readily
visible by noting any rungs that appear to be at an angle other than 90 degrees to the cable.
e. Inspect the swedged eyes at the floor attachment points for slippage or cable movement of any kind.
f. Make necessary inspection entries on appropriate form.
5.11 FAST ROPE INSERTION EXTRACTION SYSTEM (FRIES)/FAST ROPES (MIL SPEC: MIL-F-44422).
5.11.1 General. Fast Rope/FRIES are made of interwoven hemp with a diameter of approximately 2 inches with a
hook-up point on one end. Lengths will vary, depending on the needs of the mission (e.g., terrain, tactical environment, or
user requirements), but usually are found in 60, 90 and 120 foot standard lengths. Fast Ropes provide a quick means to
deploy personnel when aircraft cannot land. Extraction loops integral to the FRIES rope allows the team to be lifted and
moved to an alternate location.
5.11.2 Configuration. Fast ropes are configured on aircraft by attaching the loop end of the fast rope to the aircrafts
H/FRIES bar or approved attachment assemblies. The remainder of the rope is coiled and secured to the aircraft via a tie
down device.
5.11.3 Application. The Fast/FRIES rope is intended for use by personnel performing helicopter personnel infiltration
operations when it is impossible for the helicopter to make a landing on land or water. The Fast/PRIES rope is used to
infiltrate personnel to the ground from the helicopter.
TO 00-25-245
5-16
5.11.4 Function. The Fast/FRIES rope is configured to the aircrafts II/FRIES bar or approved attachment assemblies.
From a hover the Fast/FRIES rope is deployed to the ground allowing personnel to slide down the rope and recover
themselves on the ground. When using the FRIES rope for extraction, The FRIES rope is configured to the aircrafts FRIES
bar or approved attachment assemblies. From a hover the FRIES rope is deployed to the ground allowing personnel to hook
into the rope. Once all personnel are secured to the rope the aircraft can lift the personnel off the ground and fly away to a
new location.
5.12 FRIES/FAST ROPES MAINTENANCE AND INSPECTION (MIL SPEC: MIL-F-44422).
5.12.1 Inspection. Before conducting a FRIES operation, inspect all FRIES equipment for serviceability and readiness for
use.
• Checks the woven loop on the mount end for excessive wear or chemical contamination.
• Checks the rope along its entire length for fraying, cuts, and chemical contamination. Inspect for any cut, chafe, or
nicks that affect integrity of the rope.
• Do not use a rope that is severely frayed. (Light fraying on the rope from normal use does not weaken the rope.)
• Do not use a rope when any single strand is cut halfway through or has two or more cuts that penetrate one-third or
more through any strand’s thickness within 1 foot of the running length of the FRIES.
• Inspects the rope for contamination of acid, alkaline compounds, saltwater, fire extinguisher solutions, or petro-
leum-based solvents. Changes in color caused by chemicals are usually blotchy and have an unusual odor. Although
used ropes gradually change color, such changes do not indicate a decrease in strength unless the change is due to
contact with strong chemicals. Changes occurring because of use are usually uniform throughout the length of the
rope.
• Inspects the extraction loops to the same standard as the main rope. Ensures the woven attachment loops are secure.
• Make necessary Inspection entries on appropriate form.
5.12.2 Cleaning.
Use a fresh water container or an open hose to rinse FRIES ropes. High pressure washers will damage rope fabric
and decrease service life. Failure to comply could result in damage to, or destruction of, equipment or loss of
mission effectiveness.
Equipment that is exposed to salt water or becomes imbedded with dirt or mud should be washed and rinsed in fresh water
(within 72 hours) and hung up to dry (indoors) on hardwood pegs (out of direct sunlight).
5.12.3 Storage. FRIES ropes must always be stored in a clean, cool, dry space out of direct sunlight and free of
chemicals or chemical vapors. Equipment that becomes wet with fresh water should be hung up to dry (indoors) on
hardwood pegs.
