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 not get 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 350kv20 Feet Over 350KV50 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 20015 over 200 to 34520 over 345 to 50025 over 500 to 75035 over 750 to 1,00045 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: 1.Spotter must be in continuous contact with operator 2.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.: 3.Be positioned to effectively gauge the clearance distance 4.Where necessary, use equipment that enables spotter to communicate directly with operator, such as radio or telephone 5.Give timely information to the operator so that the required clearance distance can be maintained

29 29 Could you get within 20 feet of a power line? YESNO Option #1 Deenergize & Ground Encroachment Prevention Measures Option #3 Ask Utility for Voltage and Use Table 4 (with minimum clearance distance) Option #2 20-foot Clearance No Further Action 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*

30 Operation INSIDE Table 4  ALL of the following MUST be met: (41 items)  Notify Crane Safety Program at L&I –(360) 902-4943 or LNICranes@Lni.wa.gov  Employer determines it is infeasible to perform job without breaching minimum approach distances  After consultation with utility owner/operator it is determined infeasible to deenergize & ground power lines or relocate the power lines

31 Operation INSIDE Table 4 cont.  Power Line owner/operator determines the minimum clearance distance  Hold a planning meeting with utility owner/operator to determine the procedures to be followed in order to prevent electrical contact – procedures must include: –Deactivation of device that automatically reenergizes circuit in event of power line contact –Employ a dedicated spotter – Spotter must:

32 Operation INSIDE Table 4 cont. –Be equipped with a visual aid to assist in identifying the minimum clearance distance –Be positioned to effectively gauge clearance distance –Use equipment that enables the dedicated spotter to communicate directly with the operator –Give timely information to the operator –Dedicated spotter must be a Qualified Signal Person (see WAC 296-155-53302)

33 Operation INSIDE Table 4 cont.  Have an elevated warning line in view of the operator with high-visibility flags  Use an insulating link* installed at a point between the end of the load line and the load  All employees who may come into contact with the equipment must wear gloves rated for the voltage involved  Use nonconductive rigging

34 Operation INSIDE Table 4 cont.  Use range limiter (if equipped) that is set to prevent breaching minimum clearance distance  If tag line is used it must be nonconductive  Barricade a perimeter at least 10 feet away from crane to prevent unauthorized entry  Employees must be prohibited from touching the load line above the insulating link

35 Operation INSIDE Table 4 cont.  Only essential employees are permitted in the area of the crane and load  The crane must be properly grounded  Insulating line hose or cover-up must be installed by the utility owner/operator  Procedures are documented and available on- site  The following personnel must meet with the utility owner/operator to discuss procedures:

36 Operation INSIDE Table 4 cont. –Crane user, crane operator, ALL workers that will be in the area of the crane or load  Employer must ensure procedures are implemented  Employer must identify one person who will direct the implementation of the procedures  If a problem occurs implementing the procedures or it is found that the procedures are inadequate, new procedures must be developed or deenergize power lines

37 Operation INSIDE Table 4 cont.  All safety devices, operational aids must meet manufacturer’s procedures for use  The employer must train each employee and crew member assigned to work with the crane as follows: –Procedures to be followed to prevent electrical contact –Information regarding the danger of electrocution from the operator simultaneously touching the crane and ground
