• Synthetic Rope-Lifelines-Twisted Ropes

    Twisted Rope Grasp the rope with both hands and rotate the lifeline. Inspect strands form end to end. Remember to check inner strands for signs of damage, deterioration, or chemical attack. Synthetic fibre ropes will show a reduction in strength when used at elevated temperatures. For exposure to excessive temperature specific for the rope fibre refer to the rope manufacturers specification and instructions. Damage and deterioration may not show up through a sight (visual) inspection only-manual (touch) inspection is equally important. Rope Diameter Weakened areas from extreme loads will appear as a noticeable change in original diameter. The rope diameter should be uniform throughout. If areas appear to be reduced more than 5% from original rope diameter remove from service-(i.e.: 5/8" rope, 5% reduction would be approx. 1/32"-calipers can be used to measure.)
    Visual and Touch Inspection
    Select Pass Criteria or Fail Criteria
  • Indicates heat damage
  • Indicates heat damage
  • Indicates possible fall
  • Indicates heat damage
  • Check with Manufacturer
  • *Hockling: unraveling of the lanyard due to constant turning in the same direction or shock loading.
  • Depends on cause of discolouration but may indicate chemical attack or UV degradation.
  • Thimbles and Eyes Thimbles (steel or plastic) must be seated firmly in the eye. Thimbles must not show any sign of damage. Check around the eye itself for damage, wear or deterioration.
    Visual and Touch Inspection
    Select Pass Criteria or Fail Criteria
  • White stress marks, thimble collapsing over itself.
  • Due to cuts, nicks, abrasions, fraying, fused areas (look for same indicators as you would for the rope itself).
  • Eyes with metal thimbles - look for rust in or around the eye.
  • Rope Splices In the construction of the lifeline the rope is spliced around a plastic or metal thimble. Eye splices in twisted rope having three or more stands shall have a minimum of four tucks (ANSI Z359.1-1992). (CSA-Z259.1.95 requires a minimum of 5 full tucks.) Both Standards require the ends secured to prevent unraveling.
    Visual and Touch Inspection
    Select Pass Criteria or Fail Criteria
  • Look for tape, shrink wrap tube, stiffening agent. (Most common agents used by manufacturers.)
  • Look for the same indicators as you would for the rope itself.
  • Snap Hooks Snap hooks should be of the self-locking type. Snap hooks are generally proof tested to 3,600 lbs. and have a minimum tensile strength of 5,000 lbs.

  • Snap Hook Locking Mechanism
    Visual and Touch Inspection
    Select Pass Criteria or Fail Criteria
  • (Keeper should open freely)
  • (Locking mechanism should return to engaged position)
  • Snap Hook Keeper
    Visual and Touch Inspection
    Select Pass Criteria or Fail Criteria
  • Check keeper spring action by opening the keeper and releasing. (Keeper should return to closed position without hanging up. It should not close slowly).
  • (Keeper should not open)
  • Check to see the keeper is seated firmly on the sap hook nose-there should be no side play (lateral movement).
  • Tagging System Lifelines must have a legible tag identifying the model, date of manufacture, name of manufacture, limitations, and warnings. • Check tag for date of manufacture and remove from service if past adopted service life policy. • If tagging system is missing or not legible remove lifeline from service.
  • Cleaning and Storage Rope can be washed to remove dirt or abrasive particles. Use a solution of mild detergent and cold water. (Note: Washing can remove any coatings that may have been added to enhance the performance of the product) Hang to dry away from heat, steam, or long periods of sunlight. Lifeline must be dry before storage. Storage area clean, dry, and free from exposure to fumes, heat, direct ultraviolet light, sunlight and corrosive elements. Lifelines should be kept off the floor to provide ventilation underneath. Never store directly on a concrete or dirt floor. Note: Never store lifelines next to batteries as chemical attack on the lifeline can occur if battery leak.
