18.5.8 Protection and Packing

If abrasion or heat generated by friction is likely to occur, consideration should be given to the use of a sling which is fitted with a protective sleeve. Friction occurs in many ways associated with the load or the slinging method used. Even small amounts of movement of the load within the sling can cause heat, generated by friction, that is sufficient to damage the sling. Similarly, if the rope is allowed to rub one part with another, high temperatures can result, e.g. if the sling is used in choke hitch unless the bight is arranged at the natural angle of 120°, it will move to adopt this position as the load is taken. Whilst the safe use of the sling calls for care to be taken to minimize or avoid these practices, additional protection by way of a sleeve should be considered. Care must also be taken to protect the sling from edges and corners that might damage the sling. Protective sleeves may also be used for this purpose or, alternatively, consideration should be given to the use of suitable packing. (See section 1 1.A5.5.7 Control of Lifting Equipment, Storage, Handling and Inspection) It should be noted that smaller diameter ropes are more prone to the effects of wear, abrasion and friction as more of the yarns are exposed on the surface of the rope than with larger diameter ropes.
