(b) stopping crane operations if alerted to an unsafe condition affecting those operations. (c) ensuring that the preparation of the area needed to support crane operations has been completed before crane operations commence. (d) ensuring necessary traffic controls are in place to restrict unauthorized access to the crane’s work area (e) ensuring that personnel involved in crane operations understand their responsibilities, assigned duties, and the associated hazards. (f ) addressing safety concerns raised by the operator or other personnel and being responsible if he decides to overrule those concerns and directs crane operations to continue. (In all cases, the manufacturer’s criteria for safe operation and the requirements of this Volume shall be adhered to.) (g) appointing the signalperson(s) and conveying that information to the crane operator. (h) ensuring that signalperson(s) appointed meet the requirements of Section 5-3.3. (i) allowing crane operation near electric power lines only when the requirements of para. 5-3.4.5 and any additional requirements determined by the site supervisor have been met.

RGR RM REV 03/13 10-1.8: Identification Manufacturer’s identification and rated load identifica- tion shall be forged, cast, or die stamped on a low-stress and non-wearing area of the hook. Alternately, if the hook is used in conjunction with equipment described in other volumes of the B30 Standard, the equipment manufacturer’s identification and rated load identifica- tion shall be forged, cast, or die stamped on a low-stress and non-wearing area of the hook. 10-1.10.6 Repairs and Modifications (a) Any conditions disclosed by the inspections performed in accordance with the requirements of para. 10-1.10.3 or 10-1.10.4 shall be corrected by repair or replacement before continuing to use the hook. All repairs and modifications shall be approved by the manufacturer or a qualified person. (b) Hooks having damage or wear described as follows shall be repaired or replaced: (1) cracks, nicks, and gouges. Repair of cracks, nicks, and gouges shall be carried out by a designated person by grinding longitudinally, following the contour of the hook, provided no dimension is reduced more than 10% (or as recommended by the manufacturer) of its original value. (2) wear exceeding 10% (or as recommended by the manufacturer) of the original sectional dimension (3) any visibly apparent bend or twist from the plane of the unbent hook (4) any distortion causing an increase in throat opening of 5%, not to exceed 1⁄4 in. (or as recommended by the manufacturer) (5) inability of self-locking hooks to lock (c) A hook latch that is inoperative shall be repaired, replaced, or removed if not required. (d) If a required latch is inoperable and cannot be immediately repaired or replaced, the hook shall be sufficiently moused to retain loose items as defined in para. 10-1.3(c) until the latch is repaired or replaced. (e) When reassembling shank hooks, original securing methods or manufacturer’s recommendations shall be followed. (f) All replacement parts shall be at least equal to the original manufacturer’s specifications. (g) Hooks without provision for latches may be moused to retain loose items as defined in para. 10-1.3(c).
