Static electricity is primarily caused by:

• Chemical reactions within an electrical circuit.

• A continuous flow of electrons through a conductive material.

• The magnetic field generated by alternating current.

• An imbalance of electrical charges on the surface of materials.

Which of the following PPE is essential when working on live electrical systems?

• Welding mask

• Cotton gloves

• Insulated gloves and boots

• Rubber sandals

What is the purpose of using lock-out/tag-out procedures?

• To warn others not to touch equipment

• To decorate control panels

• To increase voltage

• To monitor current usage

A worker notices a damaged extension cord with exposed wires. According to risk assessment principles, what should be their immediate action?

• A. Carefully use the cord, avoiding contact with the exposed wires.

• B. Reduce the power load on the cord to minimize the risk.

• C. Immediately remove the cord from service and report the hazard.

• D. Temporarily repair it with electrical tape and continue using it.

What is the primary purpose of electrical grounding in a circuit?

• To make electrical devices work faster.

• To increase the flow of electricity.

• To provide a safe path for excess electrical current to the earth.

• To reduce the voltage in a circuit.

What is the FIRST and MOST critical step you should take when you witness someone receiving an electric shock?

• Shout to alert others nearby.

• Immediately grab the person to pull them away from the electricity.

• Ensure your own safety by turning off the power source if possible.

• Begin administering CPR to the person.

7. Imagine you cannot turn off the main power switch. Which of these actions would be the MOST appropriate next step to safely separate someone from an electrical source?

• A. Carefully push the person away from the source using a dry wooden stick or other non-conductive object.

• B. Wait for emergency services to arrive before taking any action.

• C. Use a metal tool to pry the electrical wire away from the person.

• D. Wrap your hands in a thick, dry cloth and quickly pull the person away.

Why is it important for appliances with metal casings, like toasters and washing machines, to be properly grounded?

• A. To make them more aesthetically pleasing.

• B. To reduce the weight of the appliance.

• C. To improve the appliance's performance.

• D. To prevent the metal casing from becoming electrically charged in case of a fault.

Which of the following best describes how proper electrical insulation prevents short circuits?

• A. By absorbing excess electrical energy.

• B. By keeping conductive wires separated, preventing unintended current flow.

• C. By increasing the voltage between wires.

• D. By allowing electricity to flow more freely.

After ensuring the victim is no longer in contact with the electrical source and checking for responsiveness and breathing, what is the next crucial step you should take, regardless of their apparent condition?

• A. Call for emergency medical help immediately.

• B. Apply antiseptic cream to any visible burns.

• C. Offer them food and drink to help them recover.

• D. Encourage them to stand up and move around to regain circulation.
