The Assistant Chief of Administration
A unit of voltage equal to 1000 volts, e.g., 50 kv = 50,000 volts.
Low Voltage Line
Electrical line rated at 750 volts or less.
Vertical pipe that serves as conduit for electrical service wires.
The length of the span between two poles or towers is the minimum clearance to maintain in all directions from downed wires or a damaged pole.
Only utility company personnel shall
cut electrical wire drip loops, open
transformers, or pull power meters.
Maintain the following distances between aerial equipment and energized electrical lines
i. At least ten feet from energized electrical lines rated up to 50 kv
ii. At least ten feet plus 0.4 inches for each 1 kv from energized electrical lines rated above 50 kv
For field use, TFD personnel shall maintain a distance of
ten feet plus one foot for each insulator skirt between electrical lines rated above 50 kv and aerial equipment.
a. This distance from lines shall also be maintained between firefighters using the aerial and their tools.
For low voltage lines, TFD personnel shall
keep aerial equipment far enough away from the lines to prevent firefighters from contacting the energized conductor.
In-line GFCI protection is required for

b. Lower sump pumps on a rope.
c. Remove portable generators from apparatus and set them on the ground before using.
d. Use only extension cords rated at a minimum of 20 amps.
If water is necessary, maintain a minimum distance of
20 feet and use fog streams, not solid streams.
For FOR DISMOUNTING A STATIONARY APPARATUS OR
VEHICLE IN CONTACT WITH OR ABOUT TO BE IN CONTACT WITH
