Based on the risk formula if the probability of tipping over while working from a bucket
truck is low but the consequence could be very high why is the work considered high
risk - Correct Answers -Lineman work is considered high risk because the

Extended reach
Lock to lock
What is the purpose for inflating a rubber glove when doing a pre use inspection? -
Correct Answers -To inspect for any air leaks
What is the difference between a Job briefing and a Job plan - Correct Answers -Job
planning includes upstream documentation , written job sequence identification of major
hazards Job briefing happens after / before work
Name two ways to positively identify a natural wire - Correct Answers -Check if
grounded to pole ground
Check for neutral connections to transformer
How can an isolated line be proven to be de-energized? - Correct Answers -Loto and
use pd50 or hot horn
What tests are performed before entering a confined space - Correct Answers -Oxygen
deficiency, flammable gases and vapors
, What are two signs that a coworker may be suffering from heat stress - Correct
Answers -Clammy skin, pale and confusion
How can a lineman help protect the public from making contact with power lines -
Correct Answers -Use barricades, cover dug holes, traffic control, covers over hot
meters
How can a lineman reduce the risk of a pole falling to the ground while working aloft? -
Correct Answers -Support the pole with a line truck
Name four safety sources that are a necessity for line work - Correct Answers -CPR,
aed, pole top rescue, fire fighting bucket rescue
What physical matter is flowing in an electrical current - Correct Answers -The
transferring of electrons from one atom to another is electrical current
How is high voltage, over 750 V, measured safely - Correct Answers -Measurement of
higher voltages is done at substations using voltage transformers (ut) to bring a
representative voltage into the control room
How can a person get into trouble when measuring voltage with a multimeter - Correct
Answers -It is to easy to mistakenly plug the test leads into current jacks when testing
voltage
Why does a person normally not feel anything when hands are placed on easy post of a
car battery - Correct Answers -The potential is only 12v which is not high enough to

Do electrons travel at the speed of light in an electrical circuit - Correct Answers -no the
speed of electrons in a conductor is about 0.0001 inches. Voltage travels at the speed
of light
Does electrical current stop once it gets to the load it is feeding - Correct Answers -No
electrical current needs a return path
Why is opening a ground wire or a neutral on an energized circuit dangerous - Correct
Answers -An electrical current could be interrupted when a current is interrupted a
voltage will appear across the open point
If a circuit is carrying 100 A, what portion of that current could induce ventricular
fibrillation and probably death - Correct Answers -100 milliamperes
