• Use the auger guide to facilitate the starting of a <br /> straight hole through hard ground or a pavement. <br /> The operator and tool handler should establish a system of <br /> responsibility for the series of various activities required for <br /> auger drilling, such as connecting and - disconnecting auger <br /> sections, and inserting and removing the auger fork. The operator <br /> must ensure that the tool handler is well away from the auger <br /> column and that the auger fork is removed before starting rotation. <br /> • Only use the manufacture 's recommended method of securing <br /> the auger to the power coupling. Do not touch the <br /> coupling or the auger with your hands, a wrench, or any <br /> other tools during rotation. <br /> Whenever possible, use tool hoists to handle auger <br /> sections. <br /> • Never place hands or fingers under the bottom of an auger <br /> section when hoisting the auger over the top of the auger <br /> section in the ground or other hard surfaces such as the <br /> drill rig platform. <br /> • Never allow feet to get under the auger section that is <br /> being hoisted. <br /> • When rotating augers, stay clear of the rotating auger <br /> and other rotating components of the drill rig. Never <br /> reach behind or around a rotating auger for any reason <br /> whatever. <br /> • Use a long-handled shovel to move auger cuttings away <br /> from the auger. Never use your hands or feet to move <br /> cuttings away from the auger. <br /> • Do not remove earth from rotating augers. Augers should <br /> be cleaned only when the drill rig is in neutral and the <br /> augers are stopped from rotating. <br /> 2 .5.17 Safety During Rotary And Core Drilling <br /> Rotary drilling tools should be safety checked periodically and <br /> replaced when necessary. <br /> • Water swivels and hoisting plugs should be lubricated and <br /> checked for "frozen" bearings before use. <br /> • Drill rod chuck jaws should be checked periodically and <br /> replaced when necessary. <br /> • The capacities of hoists and sheaves should be checked <br /> against the anticipated weight to the drill rod string <br /> plus other expected hoisting loads. <br /> Special precautions that should be taken for Safe rotary or core <br /> drilling involve chucking, joint break, hoisting, and lower of <br /> drill rods: <br /> Only the operator of the drill rig should brake or set a <br /> manual chuck so that rotation of the chuck will not occur <br /> prior to removing the wrench from the chuck. <br /> 2.5-15 <br />
