  18. Power Line Safety 296-155-53408

  19. Power Line Safety Requirements • If the crane, load, or rigging could get closer than 20/50 feet to an energized power line there are new safety requirements which apply. • If the crane, load, or rigging can notget closer than 20/50 feet to the power line even if the crane is operated at its maximum working radius, the 20/50-foot requirement is satisfied. • Minimum approach distance: Up to 350kv 20 Feet Over 350KV 50 Feet

  20. Power Line Safety Requirements(Part L before 2/1/2012) • For energized power lines rated at or below 50kV the minimum approach distance shall be 10 ft. • For lines rated over 50 kV., minimum clearance between the lines and any part of the crane or load shall be 10 feet plus 0.4 inch for each 1 kV. over 50 kV., or twice the length of the line insulator, but never less than 10 feet

  21. Power Line Safety Requirements(Table 4) Minimum Clearance Distances Table Voltage Minimum clearance distance up to 50 (kV) 10 (feet) over 50 to 200 15 over 200 to 345 20 over 345 to 500 25 over 500 to 750 35 over 750 to 1,000 45 That was easy

  22. Power Line Safety Requirements Identify the Work Zone • Define the work zone by demarcating boundaries such as flags, or a device such as a range limit device or a range control warning device and prohibiting the operator from operating past those boundaries. Note Flags

  23. If the crane or load COULD get closer than 20/50 feet of Power Lines in the Work Zone • Crane operations near power lines, use one of 3 Options • Option 1 - Deenergize & Ground Power lines • Option 2 - Maintain 20/50 foot clearance • Option 3 - Obtain power line voltage from Utility Owner/Operator and ensure the crane or rigging does not get closer than the distances listed in Table 4

  24. Power Line Safety Requirements • Options 2 and 3 require the following: • Conduct a planning meeting with crane operator, & all workers who will be in the area of crane & load • This meeting must address the location of the power lines and the steps that will be implemented to prevent encroachment-electrocution • If tag lines are used they must be nonconductive • Erect elevated warning line, barricade, or line of signs, in view of the operator, equipped with flags or similar high-visibility markings (opt 2 = 20/50 feet; opt 3 = Table 4)

  25. Nonconductive • Nonconductive means that, because of the nature and condition of the materials used, and the conditions of use (including environmental conditions and condition of the material), the object in question has the property of not becoming energized (that is, it has high dielectric properties offering a high resistance to the passage of current under the conditions of use).

  26. Power Line Safety Requirements • Options 2 and 3 also requires at least one of the following: • Proximity Alarm * • Dedicated Spotter that is also a “Qualified Signal Person” • Range Control Warning Device • Range Movement Limiter • Insulating Link * • * Currently, Proximity alarms and Insulating Links do not meet the National Recognized Testing Laboratory (NRTL) requirements.

  27. Power Line Safety Requirements • If Dedicated Spotter is used, 5 rqmt. must be met: • Spotter must be in continuouscontact with operator • Be equipped with a visual aid to assist in identifying minimum clearance distance • Examples of visual aid include: Clearly visible line painted on ground, clearly visible line of stations, line-of-site landmarks (such as a fence post and building corner)

  28. Power Line Safety Requirements • If Dedicated Spotter is used cont.: • Be positioned to effectively gauge the clearance distance • Where necessary, use equipment that enables spotter to communicate directly with operator, such as radio or telephone • Give timely information to the operator so that the required clearance distance can be maintained

  29. Could you get within 20 feet of a power line? YES NO Option #1 Deenergize & Ground No Further Action Encroachment Prevention Measures Option #2 20-foot Clearance • Planning Meeting • If Tag Lines are Used, They Must be Nonconductive • Elevated Warning Lines, Barricades, or Line of Signs • PLUS (Choose One): • Proximity Alarm*, Spotter, Range Control Warning Device, Range Limiter, or Insulating Link* Option #3 Ask Utility for Voltage and Use Table 4 (with minimum clearance distance)
