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.
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.
Isolation and tagging (no locks) is acceptable for an overhead
distribution circuit under some of the following conditions:
,age 2 of 43
......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: ......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:
,age 3 of 43
......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:
......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: ......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:
, age 4 of 43
......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.:
......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.
According to the CAN/ULC S801, what is the LEAST DESIRABLE
type of fall protection: ......ANSWER........Fall Arrest System (FAS)
