Power Line Safety 296-155-53408

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 350kv 20 Feet Over 350KV 50 Feet

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

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

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

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

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)

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).

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.

Power Line Safety Requirements If Dedicated Spotter is used, 5 rqmt.

must be met:1. Spotter must be in continuous contact

with operator2. 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)

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

Could you get within 20 feet of a power line?

YES NO

Option #1 Deenergize & Ground

Encroachment Prevention Measures

Option #3Ask Utility for Voltage and Use Table 4 (with minimum clearance distance)

Option #220-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*

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

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:

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)

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

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

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:

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

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

Operation INSIDE Table 4 cont.– The importance of the operator remaining inside

the cab except where imminent danger of fire, explosion, or other emergency that necessitates leaving the cab

– The safest means of evacuating from the crane that may be energized

– The danger of potentially energized zone around the crane (step potential)

– The need for crew in the area to avoid approaching or touching the crane or load

Operation INSIDE Table 4 cont.– Safe clearance distance from power lines– Power lines are presumed energized unless utility

owner/operator confirms them insulated– The limitations of an insulating link, proximity

alarm, and range control device– The procedures to be followed to properly ground

crane and limitations of grounding
