The minimum <br /> distance for drill rig clearance is 25 feet unless special <br /> permission is granted by the utility company. When a drill rig <br /> must be maneuvered in tight quarters,the presence of a <br /> second person is required to ensure adequate clearance. If <br /> backing-up is required,two ground guides will be used:one <br /> in the direction the rig is moving and the other in the <br /> operator's normal field of vision. <br /> Materials stored in the vicinity of drill rigs may pose Move tools,materials,cords,hoses,and debris to prevent trip <br /> various hazards to employees. hazards and contact with moving drill rig parts.
