1. As per CAN/ULC S801, on an electrical distribution overhead utility line
circuit, verification of voltage absence can be achieved by: - Answer✅
Using an approved voltage detector.
2. Isolation and tagging (no locks) is acceptable on an overhead
distribution circuit under some of the following conditions, EXCEPT for: -
Answer✅ The isolation can be operated from the ground directly at
the base of a structure.
3. Isolation and tagging (no locks) is acceptable for an overhead
distribution circuit under some of the following conditions: - 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.
1 | 32
,4. Consider that a circuit has been isolated, tagged and grounded. workers
returning the next day must: - Answer✅ Visually check grounds to
verify they are in good order, secure and test for voltage.
5. For lockout purposes, energy isolating devices shall be labelled or
marked using a standardized nomenclature and format to indicate their
function. Identification shall include: - Answer✅ The equipment type,
energy type, and magnitude.
6. 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: - Answer✅ The isolation points are
only simple single step actions.
7. A high voltage utility or electrical company is authorized to use Complex
Lockout (tag permitting) under what regulatory condition: - Answer✅
A variance application has been approved by the provincial authority.
8. Utilities often use a permitting system due to special circumstances of
which conventional lockout is impracticable. The following are justified
approaches to this process: - Answer✅ 1. The isolation points are
2 | 32
, 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.
9. Work on a distribution line must consider the following items when
performing isolation and de-energizing of the circuit.: - 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.
10. According to the CAN/ULC S801, what is the LEAST DESIRABLE type of
fall protection: - Answer✅ Fall Arrest System (FAS)
11. Within Z259.14 standards fall restriction equipment (FRE) may only be
leather in subcomponents or elements that are NOT exposed to: -
Answer✅ A dynamic load.
12. As per Z259 standards, energy absorbing lanyards shall be classified
according to their ability to absorb the kinetic energy from a fall as
