Why should wet conditions be avoided to ensure electrical safety?
Wet conditions increase the voltage in an electrical circuit, leading to short circuits.
Water acts as an insulator, preventing electricity from flowing properly.
Wet conditions reduce the resistance of the human body, increasing the risk of electric shock.
Water creates a direct path to the ground, causing appliances to overheat.
Which of the following scenarios demonstrates a violation of safety-related work practices for electrical safety?
A technician uses insulated tools and tests for zero voltage before working on a de-energized circuit.
An electrician performs maintenance on live equipment while wearing arc-rated PPE and following minimum approach distances.
A worker inspects damaged wiring in a damp environment, assuming the circuit is off because no equipment is running.
A supervisor installs Ground Fault Circuit Interrupters (GFCIs) to reduce the risk of electrical shock in a high-risk area.
Which of the following is considered a low voltage?
60 V
110 V
230 V
50 V
What is the main function of a fuse?
To protect against overcurrent
To increase voltage
To convert AC to DC
To measure current
What should be done before working on electrical equipment?
Notify a supervisor
Use insulated tools
De-energize the equipment
Wear gloves
What is the minimum current that can cause a noticeable shock?
10 mA
5 mA
1 mA
30 mA
What is the purpose of grounding in electrical systems?
To reduce current flow
To enhance voltage

Has no effect
Makes it more dangerous
What is the role of a supervisor in electrical safety?
To perform all electrical work
To ensure workers are trained
To ignore near-misses
To handle electrical emergencies
What should be used to protect against ground faults?
Circuit breakers
Insulated tools
Fuses
GFCI
What is the recommended action if an electrical accident occurs?
Leave the area immediately
Report it at the end of the day
Assess the situation and call for help
Ignore it and continue working
What is the main hazard associated with overhead power lines?
They are only dangerous in wet conditions
They are not a concern
They can cause electric shock
They are always insulated
What is the purpose of lockout/tagout procedures?
To improve efficiency
To prevent unauthorized access
To enhance safety training
To ensure equipment is de-energized
