Current through Vol. 24-16, September 15, 2024
Rule 3387a.
(1) Material other than rubber that offers
protection equivalent to or greater than rubber may be used if the material is
certified to meet the appropriate ASTM standard tests.
(2) An insulated blanket, glove, or sleeve
shall be capable of withstanding the voltage to which it may be
subjected.
(3) Exposed conductors
or equipment, or both, except for conductors or equipment being directly worked
on, that is energized from 750 volts to 28,000 volts phase to ground and that
an employee may reach into or touch shall be isolated or covered with at least
1 of the following:
(a) An insulating
blanket.
(b) An insulating
hood.
(c) An insulating line
hose.
(d) An insulating
barrier.
(4) An employee
shall use insulating gloves and sleeves capable of withstanding the imposed
voltage when performing any of the following activities:
(a) Working directly on, or within reaching
distance of, a conductor or equipment at a nominal 750 volts or more phase to
ground, except when using barehanded techniques or a hot stick. Sleeves are not
required for an employee who performs routine switching operations in a
substation or powerhouse. An employee who uses gloves and sleeves and works
directly on or within reaching distance of a conductor or equipment energized
at more than 5,000 volts phase to ground shall do so from an insulated platform
or board or an aerial device that has an insulated basket.
(b) Connecting or disconnecting primary
neutrals, pole ground wires, or other conductors normally connected to static
wires or energized equipment, except that gloves and sleeves shall not be worn
while connecting and disconnecting a service neutral or secondary
neutral.
(c) Working on a
de-energized conductor that extends into an area in which contact may be made
with an energized conductor or exposed parts of energized equipment, unless the
conductor is grounded or isolated. Insulating sleeves are optional at voltages
of less than 750 volts phase to ground.
(5) An employee shall use insulating gloves
capable of withstanding the imposed voltage when performing either of the
following activities:
(a) When working with a
powered or manual hole digger while using booms or using winch lines to install
or remove poles or equipment where the hole digger may contact conductors or
equipment energized at a voltage of 300 volts or more phase to ground. An
employee shall not use the gloves while in the enclosed cab of the
equipment.
(b) When working
directly on a conductor or equipment energized at a voltage of more than 240
volts phase to ground. This does not include the use of test
equipment.
