may fuse the rope with the consequential sticking and jumping of turns, which can be dangerous. Polypropylene is more liable to soften than other material. To avoid fusing, ropes should not be surged unnecessarily on winch barrels. For this reason, a minimum of turns should be used on the winch barrel; three turns are usually enough but on whelped drums one or two extra turns may be needed to ensure a good grip; these should be removed as soon as practicable.
Synthetic fibre ropes should be replaced when worn or damaged and as required by the competent authority.
The method of making eye or loop splices in ropes of synthetic fibre should be in accordance with the manufacturer's instructions for the particular material of which the rope is made. As a general rule, polyamide (nylon) and polyester fibre ropes need four full tucks in the splice each with the completed strands of the rope followed by two tapered tucks for which the strands are halved and quartered for one tuck each respectively. The length of the splicing tail from the finished splice should be equal to at least three rope diameters. The portions of the splice containing the tucks with the reduced number of filaments should be securely wrapped with adhesive tape or other suitable material.
Polypropylene ropes should have at least three but no more than four full tucks in the splice. The protruding spliced tails should be equal to three rope diameters at least.
Polythene ropes should have four full tucks in the splice with protruding tails of three rope diameters at least.
Mechanical fastenings should not be used in lieu of splices on synthetic fibre ropes because strands may be damaged during application of the mechanical fastening and the grip of the fastenings may be affected by slight unavoidable fluctuations in the diameter of the strands.
If any part of a synthetic rope has come into contact with organic solvents such as paint stripper or paint, it should be discarded.
If a synthetic rope has been subjected to a severe shock, it should be carefully examined.
A natural fibre rope that has become wet should be allowed to dry naturally.
A natural fibre rope that has been, or is suspected of having been, in contact with any acid, alkali or any other substance known to cause damage to rope fibre should be taken out of service and destroyed.
Fibre ropes of diameter less than 12 millimetres should not be used to lift materials.
