Make a Safety Boundary
|
-
Safety clearance boundaries can prevent power line contacts.
Make a portable safety barrier to keep workers and equipment a safe distance
from overhead lines. Federal laws stipulate at least 10 feet of clearance from
high-voltage lines. State and local laws can be even more restrictive. The
higher the voltage in the lines, the greater the clearance requirements. Power
lines carrying more than 50,000 volts, for instance, require clearances of
more than 10 feet.
-
Call your local one-call utility locator service for specific clearance
requirements.
If you will be working near power lines, notify your electric utility in
advance to determine the voltage and safe work distances, and to find out if
special safety arrangements are required.

Crane and Derrick
Working close to Entergy's energized electrical facilities is dangerous and
can result in death or serious injury. Know and comply with all Occupational
Safety and Health Administration regulations that apply to your operations.
Federal laws stipulate that if cranes or derricks will be working inside a 20
ft. clearance zone from high-voltage lines (50 ft. from lines over 350 kV),
the operator must notify the utility company to determine the voltage of the
energized lines affected. The utility company must provide the voltage
information within two working days of being notified. A specific work plan
must be developed by the operator to ensure no encroachment into the clearance
zone occurs. The work plan must include constant monitoring of work site
activity by the operator and must be agreed to by the utility company before
work begins.
For other contractor and private or public party activities, federal law
stipulates at least 10 ft. of clearance at all times from high-voltage lines.
State and local laws can be even more restrictive. The higher the voltage in
the lines, the greater the clearance requirements (refer to Table A below).
TABLE A
Up to 50kV – 10 ft.
Over 50kV to 200kV – 15 ft.
Over 200kV
to 350kV – 20 ft.
Over 350kV to 500kV – 25 ft.
Over 500kv
to 750kV – 35 ft.
Helpful rules to follow:
-
Know and comply with all OSHA regulations that apply to your operations.
-
Call your local one-call utility locator service for clarification on specific
clearance requirements.
-
If you will be working near power lines, notify your electric utility in
advance to determine the voltage and safe work distances, and to find out if
special safety arrangements are required.
