INFORM A RIGGER — PASS THE WORDPAGE 2 Always know hook load . Avoid hook failure.“Fittings shall be: (i) of a minimum breakingstrength equal to that of the sling .” – OSHA1910.184 (i) (3) (i).“It shall be determined that the weight of the load tobe lifted does not exceed the lesser of the loadrating of the hook or the load rating of theequipment of which the hook is a part.” – ASMEB30.10-1.3 (a).Maximum lift system load applied to self-lockinghook must be known for proper self-locking hookselection.TABLE 1BG100 ALLOY STEEL BK SELF-LOCKING HOOKWORKING LOAD LIMITS*BK HOOKWORKING LOAD LIMIT*TRADEIN POUNDSSIZEDESIGN FACTORMM IN4:15:16:19:15/6 7/32 27002160180012007/8 9/32 5700456038002530103/8 8800704058603900131/2 1500012000100006660165/8 2260018080150601004018/20 3/4 35300282402353015680227/8 42700341602846018970*Working Load Limits are valid between temperatures of -40 F and 400 F.

INFORM A RIGGER — PASS THE WORD Never ride on hook or load . Avoid death orinjury.Sling use regulation requires: “All employees shallbe kept clear of loads about to be lifted and ofsuspended loads.” – OSHA 1910.184 (c) (9).General worksite regulations require “No hoisting,lowering, swinging or traveling shall be done whileanyone is on the load or hook.”– OSHA 1910.180 (h) (3) (v).(d) Hooks shall not be used in such a manner as toplace a side load or back load on the hook.(See Figure 2a & 2b)(e) When using a device to close the throatopening of the hook, care shall be taken thatthe load is not carried by the closing device.(See Figure 3a & 3b)(f) Hands, fingers and body shall be kept frombetween hook and load.(i) The use of a hook with a latch does notpreclude the inadvertent detachment of a slacksling or a load from the hook. Visualverification of proper hook engagement isrequired in all cases.(j) Self-locking hooks shall be locked during use.(k) “When a hook is equipped with a latch, thelatch should not be restrained from closingduring use.” – ASME B30.10-1.3.“Operation .” – ASME B30.16-3.1aRIGHT1bRIGHTHOOKConstruction worksite regulation stipulates: “Theuse of a crane or derrick to hoist employees on apersonnel platform is prohibited, except when theerection, use, and dismantling, of conventionalmeans of reaching the worksite, such as a personnelhoist, ladder, stairway, aerial lift, elevating workplatform or scaffold, would be more hazardous or isnot possible because of structural design or worksiteconditions.” – OSHA 1926.550(g) (2).(c) Loads shall be centered in the base (bowl/saddle) of hook to prevent point loading of thehook. (See Figure 1a, 1b & 1c)“Bridles and associated rigging for attaching thepersonnel platform to the hoist line shall be usedonly for the platform and the necessary employees,their tools and the materials necessary to do theirwork and shall not be used for any other purposewhen not hoisting personnel.” – OSHA 1926.550(g) (4) (iv) (E).45 MAX.2a Never rig a hook to a load improperly .
