Section 16: Definitions
Emergency Evacuation Plan
designate actions in writing that must be taken in the event
of a fire and other
emergency.
Energized
- Electrically connected to a source of potential difference or electrical charges so as to have a
potential different from that of the ground. Synonyms: alive; current carrying; hot; live.
Equipotential Zone (EPZ)
– Any arrangement of temporary protective grounds that achieves limiting exposure
voltages to allow less current through the worker than the tolerable current.
Ferrule
- A metal compression connection installed at the point where a ground cable attaches to a ground
clamp to maintain the integrity of the electrical connection between the cable and clamp and to prevent
damage to the cable at the attachment point.
Flammable Liquid
means any liquid having a flashpoint below 100ºF (37.8ºC) except
any mixture having
components with flashpoints of 100ºF (37.8ºC), or higher, the total of which make up 99 percent or more of
the total volume of the mixture.
Fuzzing
- A method used to test the presence of voltage on a conductor by holding a metallic object near the
conductor and listening for a crackling or buzzing noise. This method is considered unreliable in detecting
lower voltages and should not be used in place of approved testing equipment on these voltages. Synonym:
buzzing the line.
Ground Rod
- A rod that is driven into the ground to serve as a ground terminal,
such as copper-clad rod, solid
copper rod, galvanized iron rod, or galvanized iron pipe. Copper-clad steel rods are commonly used during
conductor stringing operations to provide a means of obtaining an electrical ground using portable grounding
devices. Synonym: ground electrode.
Ground, Running
- A portable device designed to connect a moving conductor or wire rope, or both, to an
electrical ground. These devices are normally placed on the conductor or wire rope adjacent to the pulling
and tensioning equipment located at either end of a sag section. Primarily used to provide safety for
personnel during construction or reconstruction operations. Synonyms: ground roller; moving ground; rolling
ground; traveling ground.
