0 0 <br /> • Periodically inspect and test clutches and brakes of <br /> hoists. <br /> • Know and do not exceed the rated capacity of hooks, <br /> rings, links, swivels, shackles, and other lifting aids. <br /> • Always wear gloves when handling wire ropes. <br /> • Do not guide wire rope on hoist drums with your hands. <br /> • Following the installation of a new wire rope, first lift <br /> a light load to allow the wire rope to adjust. <br /> • Never carry out any hoisting operations when the weather <br /> conditions are such that hazards to personnel, the <br /> public, or property are created. <br /> • Never leave a load suspended in the air when the hoist is <br /> unattended. <br /> • Keep your hands away from hoists, wire rope, hoisting <br /> hooks, sheaves and pinch points as slack is being taken <br /> up, and when the load is being hoisted. <br /> • Never hoist the load over the head, body, or feet of any <br /> personnel. <br /> • Never use a hoist line to "ride" up the mast (derrick) of <br /> a drill rig. <br /> • Replace wire ropes with ones that conform to the drill <br /> rig manufacturer's specifications. <br /> 2.5. 15 Safe Use of Cathead and Rove Hoists <br /> The following safety procedures should be employed when using a <br /> cathead hoist: <br /> • Keep the cathead clean and free of rust and oil and/or <br /> grease. The cathead should be cleaned with a wire brush <br /> if it becomes rusty. <br /> • Check the cathead periodically, when the engine is not <br /> running, or rope wear grooves. If a rope groove forms to <br /> a depth greater then 1/8 inch (3 mm) , the cathead should <br /> be replaced. <br /> • Always use a clean, dry, sound rope. A wet or oily rope <br /> may "grab" the cathead and cause drill tools or other <br /> items to be rapidly hoisted to the top of the mast. <br /> • Should the rope "grab" the cathead or otherwise become <br /> tangled in the drum, release the rope and sound an <br /> appropriate alarm for all personnel to rapidly back away <br /> and stay clear. The operator should also back away and <br /> stay clear. If the rope "grabs" the cathead, and tools <br /> are hoisted to the sheaves at the top of the mast, the <br /> rope will often break, releasing the tools. If the rope <br /> does not break, stay clear of the drill rig until the <br /> operator cautiously returns to turn off the drill rig <br /> engine and appropriate action is taken to release the <br /> tools. The operator should keep careful watch on the <br /> suspended tools and should quickly back away after <br /> turning off the engine. <br /> 2 .5-13 <br />
