As per CAN/ULC S801, on an electrical distribution overhead utility line circuit,
verification of voltage absence can be achieved by: - correct answerUsing an approved
voltage detector.
Isolation and tagging (no locks) is acceptable on an overhead distribution circuit under
some of the following conditions, EXCEPT for: - correct answerThe isolation can be
operated from the ground directly at the base of a structure.
Isolation and tagging (no locks) is acceptable for an overhead distribution circuit under
some of the following conditions: - correct answer1. The isolation point is a physical and
visual like a line cut or riser removed.
2. The isolation point can only be operated by the operating authority or qualified
worker.
3. The isolation point is protected from unauthorized access such as vertical height
spacing.
Consider that a circuit has been isolated, tagged and grounded. workers returning the
next day must: - correct answerVisually check grounds to verify they are in good order,
secure and test for voltage.
For lockout purposes, energy isolating devices shall be labelled or marked using a
standardized nomenclature and format to indicate their function. Identification shall
include: - correct answerThe equipment type, energy type, and magnitude.
Utilities often use a permitting system due to special circumstances of which
conventional lockout is impracticable. The following is NOT a justified approach to this
process: - correct answerThe isolation points are only simple single step actions.
A high voltage utility or electrical company is authorized to use Complex Lockout (tag
permitting) under what regulatory condition: - correct answerA variance application has
been approved by the provincial authority.
Utilities often use a permitting system due to special circumstances of which
conventional lockout is impracticable. The following are justified approaches to this
process: - correct answer1. The isolation points are located in remote areas with difficult
or restricted access.
2. The length of time to perform the lockout is impracticable.
3. Excessive numbers of persons required to lockout.
, Work on a distribution line must consider the following items when performing isolation
and de-energizing of the circuit.: - correct answer1. Whether there are multiple sources
of energy (loop feed) on the circuit.
2. Is the line isolating device capable of interrupting load.
3. Is the line to be subject to inductive or capacitive charge.
According to the CAN/ULC S801, what is the LEAST DESIRABLE type of fall protection:
- correct answerFall Arrest System (FAS)
Within Z259.14 standards fall restriction equipment (FRE) may only be leather in
subcomponents or elements that are NOT exposed to: - correct answerA dynamic load.
As per Z259 standards, energy absorbing lanyards shall be classified according to their
ability to absorb the kinetic energy from a fall as follows: - correct answerClass E4 (4.0
kN) and Class E6 (6.0 kN) energy absorbing lanyards.
Assuming that the fall protection system is correctly being used, in what scenario might
the worker still contact the ground if they fell: - correct answerWorking 16 feet up in a
bucket truck on distribution secondary services using a six foot shock absorbing
lanyard, connected to the approved bucket anchor.
What is NOT defined as a requirement of temporary vertical life lines as per Z259
standards: - correct answer100% polypropylene fibers provide the greatest breaking
strength.
Requirements of temporary vertical life lines, as per Z259 standards: - correct answer1.
Shall be made from synthetic fibers with breaking strength of 27 kN or greater.
2. They shall be free of splices and knots, except at the terminations.
3. They shall be installed to protect against abrasion and sharp edges.
Working on an energized lattice tower requires emergency response consistent with the
associated hazards. What is NOT required as part of the emergency planning: - correct
answerDaily practice of tower rescue method.
Working on an energized lattice tower requires emergency response consistent with the
associated hazards, including: - correct answer1. A means to contact the operating
authority to de-energize the circuit.
2. Rescue equipment readily available to quickly and safely lower the worker.
3. Regular rescue practices on tower rescue at an appropriate frequency.
Z259.14 wooden pole choker devices that are designed and tested to restrict a workers
fall distance under dry, wet, and icy conditions are classified as: - correct answerType
AB device.
The voltage limits and mechanical strength of a live line tool is best specified by: -
correct answerThe manufacturers requirements.
