Electrical Safety Quiz

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

• To provide a path for excess current

• To increase resistance

Which of the following is a common source of ignition for fires?

• Overloaded circuits

• De-energized tools

• Grounding wires

• Insulated tools

What is the effect of humidity on static electricity?

• Increases static charge

• Decreases static charge

• 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
