Do not attempt lifting operations unless you understand the use of the equipment, the slinging procedures and the mode factors to be applied. Do not use defective slings or accessories. Do not force, hammer or wedge chain slings or fittings into position; they must fit freely. Check the correct engagement of fittings and appliances. Position hooks of multi-leg slings facing outward from the load. Do not lift on the point of the hook and ensure that the chain is not twisted or knotted. Back hook free legs to the master link to avoid lashing legs which might accidentally become engaged or otherwise become a hazard. Take the load steadily and avoid shock loads. Do not leave suspended loads unattended. In an emergency cordon off the area.
