26-1.8.1 Initial Inspection Prior to use, all new, altered, modified, or repaired shackles shall be inspected by a designated person to verify compliance with the applicable provisions of this Chapter. Written records are not required. 26-1.8.2 Frequent Inspection (a) A visual inspection shall be performed by the user or other designated person each day before the shackle is used. Rigging hardware in semi-permanent and inac- cessible locations where frequent inspections are not feasible shall have periodic inspections performed. (b) Conditions such as those listed in para. 26-1.8.4 or any other condition that may result in a hazard shall cause the shackle to be removed from service. Shackles shall not be returned to service until approved by a qualified person. (c) Written records are not required. 26-1.8.3 Periodic Inspection (a) A complete inspection of the shackle shall be per- formed by a designated person. The shackle shall be examined for conditions such as those listed in Section 26-1.8.4 and a determination made as to whether they constitute a hazard. (b) Periodic Inspection Frequency (1) Periodic inspection intervals shall not exceed 1 yr. The frequency of periodic inspections should be based on (a) frequency of shackle use (b) severity of service conditions (c) nature of lifting or load-handling activities
(d) experience gained on the service life of shack- les used in similar circumstances (2) Guidelines for the time intervals are (a) normal service — yearly (b) severe service — monthly to quarterly (c) special service — as recommended by a quali- fied person (c) Written records are not required. 26-1.8.4 Removal Criteria Shackles shall be removed from service if damage suchas the followingis visible and shall onlybe returned to service when approved by a qualified person: (a) missing or illegible manufacturer’s name or trade- mark and/or rated load identification (b) indicationsofheatdamage, includingweldspatter or arc strikes (c) excessive pitting or corrosion (d) bent, twisted, distorted, stretched, elongated, cracked, or broken load-bearing components (e) excessive nicks or gouges (f) a 10% reduction of the original or catalog dimen- sion at any point around the body or pin (g) incomplete pin engagement (h) excessive thread damage (i) evidence of unauthorized welding (j) other conditions, including visible damage, that cause doubt as to the continued use of the shackle 26-1.8.5 Repairs and Modifications (a) Repairs, alterations, or modifications shall be as specified by the shackle manufacturer or a qualified person.
SECTION 26-1.9: OPERATING PRACTICES 26-1.9.1 Shackle Selection (a) Shackles having suitable characteristics for the type of sling, load, hitch, and environment shall be selected in accordance with the shackle manufactur- er’s data. NOTE: The angle of loading affects the stress in the shackle. As the horizontal angle decreases, the stress increases in the shackle (see Fig. 26-1.9.1-1). (b) The ratedload ofthe shackle shall notbe exceeded. (c) Shackles that appear to be damaged shall not be used until inspected and accepted as usable under Section 26-1.8. 26-1.9.2 Cautions to Personnel (a) All portions of the human body shall be kept from between the shackle, the load, and any other rigging during the lifting or load-handling activities. (b) Personnel should stand clear of the suspended load. (c) Personnel should stand clear of rigging when it is under tension. (d) Personnel shall not ride the shackle.
26-1.9.3 Storage and Work Environments (a) Shackles should be stored in an area where they will not be subjected to damage, corrosive action, or extreme heat. (b) If extreme temperatures or chemically active envi- ronments are involved, the guidance provided in para. 26-1.6.1 or 26-1.6.2 shall be followed. 26-1.9.4 Rigging Practices (a) The screw pin threads shall be fully engaged and tight, and the shoulder should be in contact with the shackle body (see Fig. 26-1.9.4-1). (b) If a shackle is designed for a cotter pin, it shall be used and maintained in good working condition. Alterations or modifications shall comply with para. 26-1.8.5(a). (c) Contact with sharp edges that could damage the shackle should be avoided. (d) Shock loading should be avoided. (e) The load applied to the shackle should be centered in the bow of the shackle to prevent side loading of the shackle. (f) Multiple sling legs should not be applied to the shackle pin. (g) If the shackle is to be side loaded, the rated load shall be reduced according to the recommendations of the manufacturer or a qualified person (see Fig. 26-1.9.4-2).
