Q1 QUESTION 1 OF 20
under strict safety guidelines, which of the following should be used to discharge
capacitors before working on de-energized circuits.
CORRECT ANSWER
safety shorting probe
RATIONALE
A safety shorting probe is designed to safely discharge stored energy in capacitors by providing a
controlled path to ground. This action prevents hazardous voltage buildup that could cause
electrical shock or damage to equipment.
Q2 QUESTION 2 OF 20
for safety, assume that any facility constructed before 1980 has?
CORRECT ANSWER
asbestos
RATIONALE
Materials containing asbestos were commonly used in building construction before 1980. Because
asbestos fibers can cause serious health problems when inhaled, it is a safety precaution to assume
that any facility built before this year may contain asbestos.
Q3 QUESTION 3 OF 20
with of the following is the threshold at which a power source is considered high voltage in
the context of safety?
