2 WELCOME TO THE NEW DUKE ENERGY STANDARDS MANUAL. THIS MANUAL IS BEING INTRODUCED IN SECTIONS IN AN EFFORT TO MANAGE THE AMOUNT OF MATERIAL (MANUAL SHEETS) BEING DELIVERED AND IMPLEMENTED IN THE FIELD AT ONE TIME. THIS IS A MULTI-YEAR PROCESS WHICH BEGAN IN 5 AND WILL CONTINUE THROUGH AND 7. THESE STANDARDS SPECIFY HOW THE DUKE ENERGY DISTRIBUTION SYSTEM IS TO BE CONSTRUCTED IN EACH DUKE ENERGY JURISDICTION. THESE STANDARDS SHALL BE USED ON ALL NEW CONSTRUCTION. THIS INCLUDES RELOCATION PROJECTS, RECONDUCTORING PROJECTS, AND OTHER TARGETED IMPROVEMENT PROJECTS. WHERE FEASIBLE AND PRACTICAL, THESE STANDARDS SHOULD ALSO BE USED ON EXISTING FACILITIES WHEN INSTALLING NEW EQUIPMENT OR REPLACING EXISTING EQUIPMENT. GOOD ENGINEERING AND ECONOMIC JUDGMENT MUST BE APPLIED. LOCAL DESIGN ENGINEERING SHALL INDICATE THE SCOPE AND EXTENT OF WORK TO BE COMPLETED ON EACH WORK REQUEST. IF ASSISTANCE IS NEEDED BEYOND LOCAL ENGINEERING AND DESIGN, PLEASE CONTACT DISTRIBUTION STANDARDS. CONSTRUCTION QUALITY AUDIT SCORES WILL BE BASED ON REASONABLE APPLICATION OF THE STANDARDS SHOWN IN THIS MANUAL. FOR STANDARDS RELATED NEEDS NOT YET COVERED IN THE ENTERPRISE WIDE STANDARDS MANUALS, INDIVIDUALS SHOULD DEFAULT TO THEIR LEGACY MANUALS. // WHITE WHITE ADCOCK INTRODUCTION.-

3 THE NATIONAL ELECTRIC SAFETY CODE (NESC) MANDATES THE BASIC STRENGTHS AND CLEARANCES REQUIRED FOR DISTRIBUTION LINES. DUKE ENERGY CONSTRUCTION SPECIFICATIONS ARE DESIGNED TO MEET THE REQUIREMENTS OF THE NESC WHEN FOLLOWED AS SPECIFIED. DEVIATION FROM THESE SPECIFICATIONS MUST BE EVALUATED BY QUALIFIED PERSONNEL TO ENSURE THE DEVIATION DOES NOT CREATE A NESC VIOLATION. GRADE OF CONSTRUCTION THE NESC DEFINES THE GRADE OF CONSTRUCTION THAT SHALL BE USED. GRADE C IS REQUIRED FOR MOST DUKE ENERGY DISTRIBUTION LINES. UNLESS SPECIFICALLY NOTED, THESE DUKE ENERGY CONSTRUCTION SPECIFICATIONS MEET THE REQUIREMENTS OF GRADE C. GRADE B IS REQUIRED IN SPECIAL LOCATIONS AS DEFINED BY THE NESC LIKE RAILROAD CROSSINGS, LIMITED ACCESS HIGHWAY CROSSINGS, AND NAVIGABLE WATERWAY CROSSINGS. WHEN GRADE B LINES ARE REQUIRED, POLEFOREMAN SHOULD BE USED TO ANALYZE THE STRENGTH OF POLES, CROSSARMS, BRACKETS, INSULATORS, GUYS AND ANCHORS FOR COMPLIANCE. LOADING DISTRICTS THE NESC DEFINES THE LOADING REQUIREMENTS THAT SHALL BE MET BY DISTRIBUTION LINES AND STRUCTURES. COMBINED ICE AND WIND DISTRICT LOADING DUKE ENERGY SERVICE TERRITORY IN THE US LIES IN THREE COMBINED ICE AND WIND LOADING DISTRICTS. SEE MAP ON DWG..-.. FLORIDA LIES IN THE LIGHT LOADING DISTRICT. STRUCTURE, STRUCTURE MEMBERS AND LINES MUST POSSESS SUFFICIENT STRENGTH TO WITHSTAND A 9 LB/FT (APPROXIMATELY MPH) WIND AT F.. THE CAROLINAS, KENTUCKY AND OHIO AREAS OF DUKE ENERGY LIE IN THE MEDIUM LOADING DISTRICT. STRUCTURE, STRUCTURE MEMBERS AND LINES MUST POSSESS SUFFICENT STRENGTH TO WITHSTAND A 4 LB/FT (APPROXIMATELY 4 MPH) WIND AT 5 F WITH THE LINES COVERED WITH /4" RADIAL THICKNESS OF ICE.. INDIANA LIES IN THE HEAVY LOADING DISTRICT. STRUCTURE, STRUCTURE MEMBERS AND LINES MUST POSSESS SUFFICIENT STRENGTH TO WITHSTAND A 4 LB/FT (APPROXIMATELY 4 MPH) WIND AT F WITH THE LINES COVERED WITH /" RADIAL THICKNESS OF ICE. IN ADDITION, THE NESC DEFINES LOAD FACTORS THAT MUST BE APPLIED TO THE RATED STRENGTH OF STRUCTURES, STRUCTURE MEMBERS AND LINES WHEN DETERMINING THEIR ABILITY TO SUPPORT THE LOADING AT THESE ZONE CONDITIONS. // BURLISON WHITE ADCOCK MECHANICAL LOADING REQUIREMENTS AND CLEARANCES.-A

4 EXTREME WIND CONDITIONS IF A STRUCTURE, WIRES OR ANY SUPPORTED FACILITY EXCEEDS FT. ABOVE GROUND, THEN THE STRUCTURE AND SUPPORTS MUST BE DESIGNED TO MEET THE REQUIREMENTS OF EXTREME WIND LOADING. THIS IS IN ADDITION TO THE REQUIREMENTS OF COMBINED ICE AND WIND DISTRICT LOADING. THE EXTREME WIND MAPS ON DWGS..-4 AND.- SHOW THE WIND SPEED TO BE USED FOR THIS DETERMINATION. THE POLEFOREMAN PROGRAM IS THE COMPANY'S STANDARD FOR STRUCTURE DESIGN TO ENSURE COMPLIANCE WITH THIS RULE. IN ADDITION TO THE FT. RULE, THERE MAY BE TIMES WHEN EXTREME WIND LOADING REQUIREMENTS WILL BE APPLIED TO ALL STRUCTURES OF A CIRCUIT OR AREA REGARDLESS OF HEIGHT. PQR&I SHALL IDENTIFY CIRCUIT OR LOCATIONS WHERE EXTREME WIND LOADING SHALL BE APPLIED IN ADDITION TO THE FT. RULE. EXTREME ICE AND CONCURRENT WIND LOADING IF A STRUCTURE, WIRES OR ANY SUPPORTED FACILITY EXCEEDS FT. ABOVE GROUND, THEN THE STRUCTURE AND SUPPORTS MUST BE DESIGNED TO MEET THE REQUIREMENTS OF EXTREME ICE AND CONCURRENT WIND LOADING. THIS IS IN ADDITION TO THE REQUIREMENTS OF COMBINED ICE AND WIND DISTRICT LOADING. THE EXTREME ICE AND CONCURRENT WIND MAP ON DWG..- SHOWS THE ICE AND CONCURRENT WIND SPEED TO BE USED FOR THIS DETERMINATION.

9 POLEFOREMAN POLEFOREMAN IS A COMPUTER PROGRAM WRITTEN BY POWER LINE TECHNOLOGY INC. ITS FUNCTION IS CLASSING POLES, CALCULATING GUY WIRE TENSIONS AND PERFORMING JOINT USE ANALYSIS TO HELP ASSURE COMPLIANCE WITH A COMPANY'S STANDARDS AND THE NATIONAL ELECTRICAL SAFETY CODE (NESC). DUKE ENERGY HAS ADOPTED THIS PROGRAM AS ITS STANDARD TOOL FOR THIS PURPOSE. THE STANDARDS DEPARTMENT HAS CREATED AND MAINTAINS TEMPLATES FOR USE IN THE PROGRAM. A TEMPLATE REPRESENTS A BASIC SPECIFICATION WITH THE RELATIVE CONDUCTOR AND GUY LOCATIONS PRESET. THE USER MUST PROVIDE SPAN LENGTHS, GUY LEADS, EQUIPMENT CHARACTERISTICS, AND ANY ADDITIONAL CONDUCTORS OR ATTACHMENTS. THE PROGRAM UTILIZES THIS INFORMATION AND ACCURATELY CALCULATES THE MECHANICAL LOADING ON THE POLE AND GUYS BASED ON THE LOADING REQUIREMENTS OF SECTION 5 OF THE NESC. IT THEN COMPARES THE LOADS TO THE ANSI STANDARD CAPABILITIES OF THE POLES AND GUYS TO ASSURE COMPLIANCE WITH THE STRENGTH REQUIREMENTS OF SECTION OF THE NESC. DWGS..-A AND.-B ARE AN EXAMPLE OF THE OUTPUT FROM POLEFOREMAN. THE INFORMATION CAN BE USED TO VALIDATE COMPLIANCE WITH THE NESC. // BURLISON WHITE ADCOCK POLEFOREMAN.-

14 STANDARD PROCEDURES BULLETIN GENERAL INFORMATION MAINLINE CABLE: TRANSFER OF ALL CATV AND TELCO FACILITIES IS ALLOWED WHEN DUKE ENERGY AND SPECIFIC CATV AND TELEPHONE COMPANIES HAVE SIGNED A TRANSFER AGREEMENT. THIS AGREEMENT ALLOWS DUKE ENERGY TO TRANSFER ALL POLE ATTACHMENTS IN THE FOLLOWING CATEGORIES: TANGENT (STRAIGHT-LINE) CONSTRUCTION, SMALL ANGLES (DUKE ENERGY WILL NOT REMOVE OR INSTALL ANCHORS), AND DEAD-END CONSTRUCTION. ADDITIONALLY, DUKE ENERGY CAN ATTACH FOREIGN FACILITIES TO NEW POLES SET IN AN EXISTING LINE. THESE FACILITIES USUALLY CONSIST OF A /4" STRANDED MESSENGER WITH ONE OR MORE COAXIAL OR COPPER STRANDED CABLES LASHED TO THE STRAND, THE BOLTS AND CLAMPS SECURING THE CABLES TO THE POLE, AND A BONDING ATTACHMENT IF PRESENT. EXISTING TRANSFER AGREEMENTS ALL CATV COMPANIES TELEPHONE COMPANIES WINDSTREAM ALLTEL WINDSTREAM CONCORD FARMERS NORTH STATE SANDHILL FRONTIER NO TRANSFER AGREEMENTS NCDOT AND SCDOT CITY OF RALEIGH TELEPHONE COMPANIES BARNARDSVILLE AT&T HORRY RANDOLPH CENTURYLINK STAR SERVICE DROPS: SERVICE DROPS ARE ALSO TRANSFERABLE. CARE MUST BE TAKEN TO ENSURE THE DROPS ARE NOT PULLED TOO TIGHT. MOST CATV AND TELEPHONE COMPANIES DO NOT SPLICE THEIR SERVICE DROPS. BONDING AND GUYING: ALL EXISTING FOREIGN BONDING GROUNDS WILL BE TRANSFERRED. DUKE ENERGY WILL FURNISH THE # BC TO INSTALL A BONDING GROUND ON FOREIGN CABLES WHEN A NEW IN-LINE POLE IS SET. MANY CATV COMPANIES INSTALL AUXILIARY GROUNDING CONDUCTORS FOR THEIR POWER SUPPLIES. THESE "NON-TYPICAL" GROUNDING CONDUCTORS WILL NOT BE TRANSFERRED. FOREIGN SPAN GUYS AND DOWN GUYS WILL BE TRANSFERRED AS NECESSARY. DUKE ENERGY WILL NOT RELOCATE ANCHORS. THE TRANSFER SHOULD NOT BE ATTEMPTED IF THE NEW POLE LOCATION WOULD REQUIRE THE ANCHOR TO BE RELOCATED. DO NOT SPLICE DOWN GUYS. INSTALL NEW GUY STRAND WHEN NECESSARY. CABLE HANDLING TECHNIQUES - MAINLINE CABLES. CATV AND TELCO MAINLINE CABLES SHOULD BE HANDLED BY THE STRAND ONLY. DO NOT ALLOW THE CABLE TO REST DIRECTLY ON A BOLT OR THE LINE TRUCK BUCKET. A ROPE SLING SHOULD BE USED TO RAISE AND LOWER THE MESSENGER AND MAINLINE CABLE.. AVOID KINKING AND DENTING OF CATV COAX. THESE CABLES ARE EASILY DAMAGED. THE ALUMINUM SHEATH BECOMES BRITTLE OVER TIME, A SMALL DENT OR FRACTURE WILL CAUSE THE HIGH FREQUENCY TV SIGNAL TO DEGRADE DRASTICALLY.. AVOID ALL LEAD-SHEATHED CABLES. (USUALLY BELONG TO TELEPHONE COMPANY) THESE CABLES ARE PRESSURIZED, AND THE LEAD SHEATH IS EASILY PUNCTURED. 4. USE THE LASHING WIRE CATCH-OFF TOOL WHEN HANDLING LASHING WIRE. MOST TELEPHONE COMPANIES PROHIBIT THE USE OF ELECTRICAL TAPE FOR THE PURPOSE OF SECURING THE LASHING WIRE. THE LASHING WIRE IS UNDER TENSION, SO IT MUST BE BY A LASHING WIRE GRIP BEFORE LOOSENING THE LASHING WIRE CLAMP. CABLE HANDLING TECHNIQUES - SERVICE DROPS. DO NOT SAG DROPS TOO TIGHT. THE TERMINALS OF CATV AND TELEPHONE EQUIPMENT CANNOT WITHSTAND MUCH TENSION AND WILL BREAK EASILY. GENERALLY, IF THERE IS NOT ENOUGH SLACK TO FORM A DRIP LOOP, THE DROP IS TOO TIGHT OR TOO SHORT.. DRIP LOOPS MUST BE FORMED AT THE TAKE-OFF POLE AND AT LIFT POLES. JOINT USE CLEARANCES. CLEARANCES IN SECTION.7 SHOULD BE FOLLOWED WHEN MAKING JOINT USE TRANSFERS. // BURLISON WHITE ADCOCK CABLE/JOINT USE TRANSFERS X.4-

15 OVERVIEW: SERVICE INSTALLATIONS TO CUSTOMERS WHERE STRIP-MINING ACTIVITIES OCCUR (PHOSPHATE MINES, SAND PITS, ROCK QUARRIES, ETC.) REQUIRE CONFORMITY WITH FEDERAL AND STATE MINE HEALTH AND SAFETY ADMINISTRATION (MSHA) REGULATIONS RATHER THAN NESC REGULATIONS. OVERHEAD AND UNDERGROUND DISTRIBUTION FACILITIES LOCATED IN ACTIVE MINING AREAS MUST CONFORM TO THE NATIONAL ELECTRICAL CODE (NEC) AND MUST MEET CERTAIN INSPECTION CRITERIA. PERSONS OPERATING AND MAINTAINING FACILITIES IN ACTIVE MINING AREAS MUST ALSO BE CERTIFIED. SERVICE ROAD 48V SCALE HOUSE & SHOP POLICY: DUKE ENERGY DISTRIBUTION CONSTRUCTION SPECIFICATIONS ARE DESIGNED TO CONFORM TO THE NATIONAL ELECTRICAL SAFETY CODE (NESC), NOT THE NEC. THEREFORE, ALL SERVICE EXTENSIONS TO SERVE NEW CUSTOMERS OR EXTENSIONS TO EXISTING CUSTOMERS MUST REMAIN OUTSIDE ACTIVE MINING AREAS. INDIVIDUAL MINE OWNERS DETERMINE THE BOUNDARIES OF AN "ACTIVE MINE", BUT GENERALLY INCLUDE AREAS WHERE BLASTING, DREDGING, AND/OR DIGGING OCCUR. MINE OWNERS SHALL PROVIDE A PLAN SIGNED BY THE MINE OWNER DEPICTING "ACTIVE MINING AREAS" AND DESIGNATING THOSE AREAS NOT COVERED BY MSHA WHERE DUKE ENERGY FACILITIES CAN BE PLACED. EXISTING CUSTOMER INSTALLATIONS WILL BE ADDRESSED WHEN THE CUSTOMER REQUESTS MODIFICATIONS TO EXISTING FACILITIES. HP PUMP 48/77 THE LOCAL MINE OWNER MAY REQUIRE SITE SPECIFIC HAZARD AWARENESS TRAINING PRIOR TO ANY DUKE ENERGY CONSTRUCTION OR MAINTENANCE ACTIVITY BEING PERFORMED ON MINE PROPERTY. THIS TRAINING, IF REQUIRED BY THE LOCAL MINE OWNER, SHOULD BE INCLUDED IN THE PRE-JOB BRIEFING. PROPOSED SERVICE TRANSFORMER 4./.5kV 4./.5kV PROCESSING SITE DUKE ENERGY FACILITIES CAN BE INSTALLED IN THIS AREA IF NOT DESIGNATED BY THE CUSTOMER AS "ACTIVE MINING AREA." PROPOSED SERVICE TRANSFORMER ACTIVE MINING AREA "ACTIVE MINING AREA" DEFINED BY THE CUSTOMER (DREDGING, DIGGING, BLASTING, ETC.). DUKE ENERGY SHALL NOT BE INSTALLED IN THIS AREA. SERVICE TO MINES // BURLISON WHITE ADCOCK.5-

16 FROM TIME TO TIME, DUKE ENERGY IS REQUESTED TO PUT "MARKER BALLS" ON DUKE ENERGY OVERHEAD DISTRIBUTION FACILITIES TO MAKE THEM MORE VISIBLE. MARKER BALL REQUESTS ARE USUALLY ASSOCIATED WITH NON-FAA CONTROLLED AIRSTRIPS OR WITH SITES WHERE HEAVY EQUIPMENT CROSSES UNDER EXISTING OVERHEAD LINES. AIRSTRIP AND CONSTRUCTION SITE OPERATIONS CAN PRESENT A HAZARD TO THE DISTRIBUTION LINES AND TO THE OPERATORS OF AIRCRAFT AND CONSTRUCTION EQUIPMENT. THE FOLLOWING PROCEDURES ADDRESS STEPS THAT ARE TO BE TAKEN TO ENSURE THE PROTECTION OF OUR DISTRIBUTION FACILITIES AND THE SAFETY OF OTHERS WHEN A CUSTOMER REQUESTS US TO INSTALL MARKER BALLS. MARKER BALLS ARE NOT FAVORED AND THE BEST SOLUTION IS ALWAYS TO RELOCATE OR PLACE THE FACILITIES UNDERGROUND. REQUESTS: WHEN MEMBERS OF THE PUBLIC REQUEST MARKER BALLS, WE WILL REVIEW THE SPECIFICS OF THE REQUEST AND, AS INDICATED, OFFER THE FOLLOWING OPTIONS:. MOVE THE LINES AT REQUESTER'S COST.. BURY THE LINES AT REQUESTER'S COST.. REQUESTER MAY PLACE POLES AND STATIC LINE WITH MARKER BALLS OUTSIDE THE CLEARANCE AREA UNDER OWNERSHIP OF THE REQUESTER AND AT REQUESTER'S COST. 4. LICENSE THE REQUESTER TO HAVE MARKER BALLS PLACED AND MAINTAINED ON OUR FACILITIES AT THEIR EXPENSE. LEGAL WILL PROVIDE THE CONTRACT TO LICENSE THE REQUESTER. THE LICENSE WILL INCLUDE PROTECTION FOR THE COMPANY BY WAY OF THE BROADEST POSSIBLE INDEMNITY OBLIGATION TO THE LICENSEE. THE REQUESTER WILL PURCHASE MARKER BALLS FROM APPROVED DUKE ENERGY MANUFACTURERS. DUKE ENERGY DESIGNER WILL CONTACT LOCAL STANDARDS' REPRESENTATIVE TO GET CURRENT APPROVED MANUFACTURERS AND MANUFACTURER'S PART NUMBER. DUKE ENERGY RESOURCES WILL INSTALL REQUESTER PURCHASED MARKER BALLS ON OUR FACILITIES AT THE REQUESTER'S COST. KNOWN DANGERS: WITH DISTRIBUTION CONFLICTS, THE APPROACH WILL BE TO CONTACT OPERATORS AND REQUEST THAT THEY CEASE OPERATIONS THAT ARE IN CONFLICT WITH OUR LINES OR PAY TO UNDERTAKE ONE OF THE FOUR OPTIONS ABOVE. EXISTING MARKER BALLS: IN PLACES WHERE WE HAVE EXISTING MARKER BALLS ON OUR FACILITIES THAT HAVE NOT BEEN PLACED AT THE DIRECTION OF A REGULATORY AGENCY, A REVIEW WILL BE MADE AND ACTION TAKEN. CUSTOMER-INSTALLED POLES AND GUY WIRE WITH MARKER BALLS. MUST BE INSTALLED AT LEAST 5 FEET AWAY FROM THE DISTRIBUTION LINE. 5' MIN.

17 A. CONSTRUCTION EQUIPMENT TRAVERSING UNDER OVERHEAD LINES. DETERMINE THE HEIGHT OF THE EQUIPMENT THAT WILL BE TRAVERSING UNDER THE OVERHEAD FACILITIES. ENSURE THAT COMPANY FACILITIES MEET NESC CLEARANCES ABOVE THE EQUIPMENT. IF THE CLEARANCE IS ADEQUATE, INFORM THE EQUIPMENT OWNER/OPERATOR THAT THE CLEARANCE IS ADEQUATE.. IF CLEARANCE ABOVE THE EQUIPMENT IS INADEQUATE TO MEET THE NESC, REQUEST THAT THE ACTIVITY UNDER THE POWER LINES CEASE UNTIL THE CONFLICT IS RESOLVED. NOTE: NESC TABLE -, FOOTNOTE 5 STATES THAT WHEN DESIGNING LINES FOR OVERSIZED VEHICLES, THE REQUIRED CLEARANCE SHALL BE INCREASED BY THE KNOWN HEIGHT OF THE VEHICLE, LESS 4 FEET. FOR EXAMPLE: IF THE LINE CLEARANCE REQUIREMENT IS FEET AND THE VEHICLE IS FEET HIGH, THEN THE LINE CLEARANCE MUST BE INCREASED BY FEET (-4= FEET) FOR A TOTAL CLEARANCE OF FEET (+= FEET). PROVIDE CUSTOMER WITH THE COST TO RAISE/RELOCATE/CONVERT (TO UNDERGROUND) THE FACILITIES TO ELIMINATE THE CONFLICT. IF THE CUSTOMER AGREES TO PAY, CONFLICT IS RESOLVED.. IF NONE OF THE ACTIONS ABOVE ARE ACCEPTABLE TO THE CUSTOMER/EQUIPMENT OWNER/OPERATOR AND/OR NO RESPONSE HAS BEEN RECEIVED IN DAYS, CONTACT THE LEGAL DEPARTMENT FOR ADVICE AND ASSISTANCE. B. CRANE AND OTHER EQUIPMENT WORKING IN CLOSE PROXIMITY TO OVERHEAD LINES FOR INFORMATION ONLY: THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION 9 CFR PART 9 CRANES AND DERRICKS IN CONSTRUCTION, REQUIRES CRANES (INCLUDES RIGGING, LOAD, ETC) AND OTHER EQUIPMENT TO STAY OUTSIDE A FOOT ZONE FROM ELECTRIC POWER LINES UNLESS ONE OF THE FOLLOWING THREE OPTIONS ARE SELECTED. OPTION. DE-ENERGIZE AND GROUND: IF THE LINE CAN BE SAFELY DE-ENERGIZED AND GROUNDED WITHOUT UNDUE HARDSHIP ON CUSTOMERS, OUR CREWS ARE AUTHORIZED TO DE-ENERGIZE THE LINE AND PROVIDE GROUNDS IN THE VICINITY OF THE WORK AREA. THE REQUESTOR MUST PAY THE COST OF PERFORMING THIS SERVICE BEFORE WORK COMMENCES. OPTION. MAINTAIN FOOT CLEARANCE: IF ANY OF THE EQUIPMENT BEING OPERATED (LOAD LINE, LOAD, ETC) HAS POTENTIAL OF ENTERING THE FOOT ZONE, MEASURES SPECIFIED IN OSHA 9.48 (b) MUST BE IMPLEMENTED TO ENSURE NOTHING ENTERS THE FOOT ZONE. OPTION. TABLE "A" CLEARANCE: TABLE "A" CLEARANCES PERMIT OPERATION WITHIN THE FOOT ZONE BUT NO CLOSER THAN FOOT TO LINES BELOW 5 KV. IF ANY OF THE EQUIPMENT BEING OPERATED (LOAD LINE, LOAD, ETC) HAS POTENTIAL OF ENTERING THE FOOT ZONE, MEASURES SPECIFIED IN OSHA 9.48 (b) MUST BE IMPLEMENTED TO ENSURE NOTHING ENTERS THE FOOT ZONE. PART (b) OF OSHA 9.48 HAS SEVERAL REQUIREMENTS THAT MUST BE MET. THESE REQUIREMENTS ARE DESIGNED TO PREVENT ANY PORTION OF THE EQUIPMENT BEING OPERATED FROM ENTERING THE CLEARANCE ZONE SELECTED. IF THE COMPANY IS REQUESTED TO PROVIDE THE OPERATING VOLTAGE OF THE DISTRIBUTION LINE BY A FIRM PLANNING TO DO WORK NEAR THE LINE, OSHA REQUIRES THIS INFORMATION BE PROVIDED WITHIN TWO WORKING DAYS. COMPANY PERSONNEL MUST NOT ATTEMPT TO EXPLAIN PART (B) OF OSHA 9.48 TO A REQUESTOR, OR ACT AS SPOTTER FOR THE REQUESTOR DURING CRANE OR OTHER EQUIPMENT OPERATIONS. // BURLISON WHITE ADCOCK REQUIREMENTS FOR CRANES AND OTHER EQUIPMENT WORKING NEAR OR UNDER DISTRIBUTION LINES.5-4

18 DEFECTIVE/FAILED MATERIAL REPORT SYSTEM WHEN REPORTING A DEFECTIVE/FAILED MATERIAL, COMPLETE A DEFECTIVE/FAILED MATERIAL TAG (ITEM # 9994 SEE FIGURES BELOW), AND ATTACH IT TO THE FAILED MATERIAL. THE TAGGED MATERIAL IS COLLECTED AT A CENTRAL LOCATION AT EACH OPERATIONS CENTER, FOR SHIPMENT BACK TO THE GENERAL WAREHOUSE IN WILDWOOD. UPON RECEIPT OF THE MATERIAL, A DEFECTIVE/FAILED MATERIAL REPORT (FORM 48) WILL BE COMPLETED AND DISPOSITIONED BY THE APPROPRIATE DISTRIBUTION STANDARDS ENGINEER. IF ANALYSIS OF THE MATERIAL FAILURE IS REQUIRED IT WILL BE PERFORMED BY THE STANDARDS ENGINEER OR SENT BACK TO THE MANUFACTURER FOR EVALUATION. ACCURATE REPORTING ENABLES DISTRIBUTION STANDARDS TO IDENTIFY POOR PERFORMING PRODUCTS, AND REMOVE THEM FROM THE SYSTEM BEFORE POWER QUALITY AND SYSTEM RELIABILITY IS ADVERSELY AFFECTED. TAG# DEFECTIVE/FAILED MATERIAL TAG ATTENTION Fill out tag completely REGION: LOCATION: Attach to material Notify appropriate standards personnel if urgent PREPARED BY DIS/GIS # PHONE # CATALOG # DATE REASON FOR RETURN FAILED IN SERVICE (NAME) Send material to Material Recovery or Distribution Standards for review If tagging a transformer, write the pole/pad ID number and "CLAIM" on the unit with a black waterproof marker TF Serial # COMMENTS: BROKEN/DEFECTIVE WHEN RECEIVED OTHER-EXPLAIN CLAIM INVOLVED?
