text: Insertion and Extraction Methods
  INSPECTION
  5-51. A certified SPIES master or rigger inspects SPIES at a minimum every 6 months or whenever the
  serviceability of the equipment is in doubt. Out-dated, spliced, abraded, or cut ropes are removed from
  service. The SPIES master or rigger inspects the ropes as follows:
  1. Inspects harness and suspension sling webbing for signs of contamination from oil, grease,
  acid, rust, cuts, twists, fading, excessive wear, or fusing (indicated by unusual hardening or
  softening of webbing fibers), fraying, burns, abrasions, and loose or broken stitching (in
  excess of three stitches). The inspector removes damaged harnesses or suspension slings and
  returns damaged equipment to supply for appropriate disposition. In some cases, riggers may
  be able to repair deficiencies.
  2. Inspects all hardware for signs of corrosion, pitting, ease of operation, security of attachment,
  bends, dents, nicks, burrs, and sharp edges. Replacing any hardware (except the chest strap
  adapter) that requires unstitching the webbing, makes the harness unserviceable.
  3. Replaces the "V" ring by cutting the strap above the stitching. A qualified rigger can fold and
  stitch a new end section for leg straps. If straps are damaged, the harness or suspension sling
  is unserviceable and must be returned to supply for appropriate disposition.
  4. Ensures rope is free of splices.
  5. Inspects the surface of the rope for splices, cuts, excessive abrasions, and snags. Cuts are
  considered excessive when four or more strands in any 5-inch length are cut. The two-to-one
  braided rope has 12 pair (24 strands) around the circumference. Abrasion is extensive when
  torn yarns are equivalent to that of four strands of any 5-inch length. A rope that has been
  subjected to heavy loads might display glazed areas where it has rubbed against hard
  surfaces. Painted or fused fibers can both produce a glazed appearance. A rope can also get
  fuzzy on the surface from long use. The effect on the strength of the rope by glazing or
  surface fuzz is negligible.
  6. Inspects the rope for signs of contamination by acid, alkaline compounds, salt water, fire
  extinguishing solutions, and petroleum-based solvents. Although ropes gradually and
  uniformly change color with use, this does not decrease its strength. However, exposure to
  strong chemicals, usually indicated by spotty discoloration on the rope, can affect the strength
  of the rope.
  7. Ensures the eye loop at the attachment point is not broken, frayed, or loose.
  SERVICE LIFE
  5-52. The SPIES master and riggers check ropes, harnesses, and suspension slings for expiration of
  service life or total life. Expiration of service is 7 years from the date the manufacturer's package is opened,
  and total life is 15 years from the date of manufacture.
  REPAIR AND CLEANING OF ROPE
  5-53. To repair the rope, the SPIES master must--
  Note: You must repair loose or broken stitching.
  1. Wash contaminated ropes with a mild detergent (such as liquid dish soap) and cold water,
  followed by a rinse in clean, fresh water. Dry the rope at room temperature (not to exceed
  140 degrees Fahrenheit).
  2. Remove stubborn oil, grease, hydraulic fluid, and other petroleum stains with the cleaning
  agent xylene (Grade A or B, TT-X 916). Use the cleaning agent as directed.
