CUSP EXAMINATION TEST QUESTIONS
ANSWERS ACCURATE REVIEW SHEET
GRADED A+
●● 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:
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:
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:
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)
●● 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.
●● As per Z259 standards, energy absorbing lanyards shall be classified
according to their ability to absorb the kinetic energy from a fall as
follows:
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:
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.
