sEAcoR <br /> STANDARD SAFETY DRILLING SAFETY SSP 30 <br /> PROCEDURES <br /> • Watch for sagging power lines before entering a site. Do not lift power4ines to gain <br /> entrance. Call the utility and ask them to lift or raise the lines or deenergize (turn <br /> off) the power. <br /> • Before raising the drill rig mast/derrick on a site In the vicinity of power lines, walk <br /> completely around the drill rig. Determine what the minimum distance from any <br /> point on the drill rig to the nearest power line will be when the mast/derrick is <br /> raised and/or being raised. Do not raise the mast/derrick or operate the drill rig if <br /> this distance is less than 20 feet (6 m), or if known, the minimum clearance <br /> stipulated by federal, state and local regulations. <br /> Keep in mind that both hoist lines and overhead power lines can be moved toward <br /> each other by the wind. <br /> • Move the drill rig with the mast/derrick down to avoid contact with power lines. <br /> • If there are any questions whatever concerning the safety of drilling on sites in the <br /> vicinity of overhead power lines, call the power company. The power company will <br /> provide expert advice at the drilling site as a public service and at no cost. <br /> Underground electricity is as dangerous as overhead electricity. Be aware and always _ <br /> suspect the-existence of-underground utilities-such as-electrical power,`gas, petroleum, <br /> telephone, sewer and water. As for assistance: <br /> • _ If a sign warning of underground utilities is located on a site boundary Do not <br /> assume that underground utilities are located on or near the boundary or property <br /> line under the sign. Call the utility and check it out. The underground utilities may <br /> be a considerable distance away from the warning sign. <br /> • Always contact the owners of utility lines or the nearest underground utility <br /> location service before drilling. Determine jointly with utility personnel the precise <br /> location of underground utility lines. Mark and flag the locations and determine <br /> jointly with utility personnel what specific precautions must be taken to ensure <br /> safety <br /> 1.4.30.12 Safe Use of Electricity <br /> Di--_ . <br /> Drilling projects sometimes require around-the-clock operations and, therefore, require <br /> temporary electrical lighting In general, all wiring and fixtures used to provide electricity <br /> corp-h&slssp-30 30_11 REVISED 11/02/92 <br />
