As per CAN/ULC S801, on an electrical distribution overhead utility line
circuit, verification of voltage absence can be achieved by: - CORRECT
ANSWER - Using 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 ANSWER
- The 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 ANSWER - 1.
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 ANSWER - Visually 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 ANSWER - The 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 ANSWER - The 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
ANSWER - A 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 ANSWER - 1. 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 ANSWER - 1.
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.

to their ability to absorb the kinetic energy from a fall as follows: - CORRECT
,ANSWER - Class 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
ANSWER - Working 16 feet up in a bucket truck on distribution secondary
services using a six foot shock absorbing lanyard, connected to the approved
bucket anchor.

CORRECT ANSWER - 1. 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.

with the associated hazards. What is NOT required as part of the emergency
planning: - CORRECT ANSWER - Daily practice of tower rescue method.
Working on an energized lattice tower requires emergency response consistent
with the associated hazards, including: - CORRECT ANSWER - 1. 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.

acceptable strategy for tool modification: - CORRECT ANSWER - A utility
worker has evaluated the tool modification and approved the change.
Live line tools can be modified to meet the needs of the work. Acceptable
strategies for tool modification include: - CORRECT ANSWER - 1. Changes
to the tool do not violate other applicable standards.
2. The tool has been inspected and tested by a professional engineer.
