Power Line Safety WAC 296-155-53408
34
Power Line Safety Requirements
 If the crane or rigging could get closer than 20/50 feet to an
energized power line there are new safety requirements which apply.
 If the crane or rigging can not get closer than 20/50 feet to the 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
35
Power Line Safety
 Crane assembly/disassembly below energized power
lines is prohibited.
 Crane assembly/disassembly inside Table 4 is
prohibited.
36
Operation of Crane/Derrick
 Identify the work zone by demarcating
boundaries. (flags, or devices/limiting)
 Determine maximum working radius/360
which includes rigging & load. If could get
closer than 20 ft of a power line.
 Employer must meet requirements in Option
(1)(2) or (3)
Power Line Safety Requirements
 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
38
Power Line Safety Requirements
Work Zone
360 degrees around the crane
(maximum working radius)
Demarcate work zone boundaries
and prohibit the operator from
operating the crane past those boundaries
Power Line Safety Requirements
 Options 2 and 3 also require the
following:
 Installing an elevated warning line
or barricade 20/50 feet from Power
Line, and
 Implement at least one of the
following:
•
•
•
•
•
Proximity alarm (OSHA exempt)
Dedicated spotter
Range control warning device
Range Movement limiter
Insulating link (OSHA exempt)
40
Could you get within 20
feet of a power line?
YES
NO
Option #1
Deenergize &
Ground
Option #2
20-foot
Clearance
Option #3
Ask Utility for
Voltage and
Use Table 4
(with minimum
clearance distance)
Encroachment
Prevention Measures
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):
• Spotter, Warning Device, Range
Limiter.
41
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
