Workers could place hands into moving parts of the rig, or loose clothing could become entangled in moving machine parts, either of which could injure a worker. • Chains, sprockets, and moving parts will be guarded. Workers will not wear loose clothing or any jewelry. Workers will not place their hands or any part of their bodies between the drill auger or rod and the drill plate. Workers should never place themselves in positions where they could come in contact with the moving drill rods or augers. The operator will verbally alert all workers and visually ensure that all workers are clear of dangerous parts of equipment before starting or engaging equipment. Workers will avoid contact with any moving auger. Means will be provided to guard against employee contact with auger. [For example, barricade the perimeter of auger or use an electronic brake activated by a presence- sensing device.] Workers could injure themselves by cleaning the augers while they are rotating. • Augers will be cleaned only when they are stopped and in neutral. They will not be restarted until the worker has given a verbal "all clear" to the operator, and the operator has visually determined that the worker is clear of the auger. Only long-handled shovels will be used to move cutting from the auger. Workers could trip or fall over open boreholes. • Cap and flag open boreholes. All open boreholes will be protected as any open excavation if they are left unattended. Pinch points. • Avoid placing hands close to moving machinery. Wear gloves, as appropriate.
