most direct influence on Safe work - Correct Answers -Lockout/tagging, protective
equipment, employee training
Why is it important to report all accidents or near misses - Correct Answers -To protect
you financially from a future flareup and so lessons learned may prevent a fatality in the
future
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 -The consequence is high risk is always high
What is the rubber glove rule for your employer? - Correct Answers -Usually cradle to
cradle but can also be ground to ground extended reach rule or lock to lock
What is the purpose for inflating a rubber glove when doing a previous inspection -
Correct Answers -Allows for closer inspection and can listen for air leaks
What is the difference between a job briefing and job plan - Correct Answers -Job plan
is written documentation of sequences possible hazards and effective barriers for each
step in a job briefing is going over the job plan
Name three high-risk Eye hazards in line work - Correct Answers -Flying particles, UV
light of electrical arc, working with acids, moving grounds
Name two ways to positively identify a neutral wire - Correct Answers -Check neutral
connections at transformer a neutral position on a pole
Why are disconnect switches in series with a circuit breaker - Correct Answers -So that
the circuit breaker can be isolated from the circuit to carry out maintenance
What are the prerequisites before entering a substation - Correct Answers -System
control requires notification before anyone entering any must've had electrical
awareness training or be under the escort by a qualified worker
, List for items in a substation design that are meant to protect the public - Correct
Answers -The outer fence and not having a gap at the bottom, secured gates, the
ground wire mesh grid extending past the fence, and warning signs
How can an isolated line be proven to be De energized - Correct Answers -Tested and
grounded number one physical open to test with approved tester and three apply
grounds
What tests are performed before entering a confined space - Correct Answers -Tests
are done for oxygen deficiency flammable gases in vapors before and after removing
cover
Name for hazards when working in excavations or trenches - Correct Answers -Oxygen
deficiency, cave-ins, utility lines and energize cables
What are two signs that a coworker may be suffering from heat stress - Correct
Answers -Confusion pale skin passing out looks like they're dying of heat stress
How can a linemen help protect the public from making contact with powerlines -
Correct Answers -Barricades, covers, traffic controllers around utility work

Correct Answers -Support the pole with a line truck boom ropes or guidelines or by
lashing a new pull along the side it
Name for safety courses that are necessary for work - Correct Answers -CPR,
defensive driving, pole top rescue, first aid
What physical matters flowing in an electrical current - Correct Answers -Electrons
How is high voltage, over 750 V, measured safely - Correct Answers -Substations using
a voltage transformer
How can a person get into trouble when measuring voltage with a multi meter - Correct
Answers -By plugging the test leads into the current jacks when testing voltage causing
it to short out
Why does a person normally not feel anything when hands are placed on each post of a
car battery - Correct Answers -The potential is only 12 V most people can feel 40 V it
does not penetrate the resistance of skin
What means can be used to positively identify the nominal voltage of a primary circuit -
Correct Answers -Nameplate on existing transformer
Do electrons travel at the speed of light in an electrical curcuit - Correct Answers -No
they move .0001 in./s
