Storage locations shall be identified with a number corresponding to the identification number on the sling. Storage locations must be in ~~ areas where slings are protected from mechanical damage, excessive heat, sparks, moisture, acid fumes, or other harmful environmental F exposures. 8.0 Examination r All slings shall be visually checked prior to use on each shift. A thorough formal examination should be made of all slings monthly by a trained designated sling tester (see Attachment E). An examination checklist shall be filled out and kept on file concerning this examination (see Attachment C). Defective rigging equipment shall not be used and shall be identified with form TVA 18004, " Defective Equipment Tag." r: 8.1 Chain Sling Examination 8.1.1 Effects of Overloading The determination to remove a chain sling from service shall not be made solely on the basis of increase in reach. An examination shall be made on an individual link basis. If any link does not hinge freely with the a adjoining link, the assembly shall be removed from service. 4 1 8.1.2 Effects of Wear If wear at any point of any chain link exceeds that shown in the table on the following page, the assembly L shall be removed from service. 8.1.3 Nicks and Gouges Sharp transverse nicks should be rounded out by grinding. ~ If the depth of the gouge or rounded out portion l exceeds the values shown in the following table, the assembly shall be removed from service. l l g ~ s n ..;.n; a ..v. p. 4x ' x; v a. l ,n
