SEACOR <br /> STANDARD SAFE'T'Y DRILLING SAFETY SSP 30 <br /> PROCEDURES <br /> for drilling operations should be installed by qualified personnel in accordance with the <br /> National Electrical Code (NFP A70-1984) with consideration of the American Petroleum <br /> Institute's recommended practices for electrical installations for production facilities(API- <br /> RP-500B). Lights should be installed and positioned to ensure that the work area and <br /> operating positions are well lit without shadows or blind spots. The following specific <br /> recommendations emphasize the safe use of electricity during land-bored drilling <br /> operations. <br /> • Before working on an electrical power or lighting system, lock out the main panel <br /> box with your own lock and keep the key on your person at all times. <br /> Install all wiring using high quality connections, fixtures and wire, insulated and <br /> protected with consideration of the drilling environment. Makeshift wiring and <br /> equipment should not be permitted. <br /> • All lights positioned directly above working areas should be enclosed In cages or <br /> similar enclosures to prevent loose or detached lamps or vapor tight enclosures from <br /> failing on workers. <br /> • Install all lights to produce the least possible glare or "blind spots" on tools, ladders, <br /> walkways, platforms and the complete working area. <br /> • Locate and guard all electrical cables to prevent damage by drill operations or by <br /> the movement of personnel, tools or supplies. <br /> • Ensure that all plug receptacles are the three-prong, U-blade, grounded type and <br /> have adequate current carrying capacity for the electrical tools that may be used. <br /> • Ensure that all electric tools have three-prong, U-blade, ground wire plugs and <br /> cords. <br /> • Do not use electrical tools with lock-on devices. <br /> • Ensure that all electrical welders, generators, control panels and similar devices are <br /> adequately grounded. <br /> • Avoid attaching electrical lighting cables to the mast/derrick or other components <br /> of the drill rig If this must be done, use only approved fasteners Do not "string" <br /> wire through the mast/derricl. <br /> Do not use poles used to hold wiring and lights for any other purpose <br /> corp-h&slssp-30 3n-19 REVISED i l /02192 <br />
