Lesson Content

Electrocution

Electrocution is a serious danger caused when electricity passes through a person’s body. It can cause severe harm or death.

What is Electrocution?

Electrocution happens when someone gets hurt or dies from electricity passing through their body. It’s a dangerous electric shock.

Causes of Electrocution

Electrocution can occur due to various unsafe practices and conditions. The following are some of the common causes of electrocution:

1. Touching uncovered wires: Unprotected wires carry electricity; touching them causes shocks.
2. Using electrical devices with wet hands: Water conducts electricity, making this very dangerous.
3. Overloading outlets: Too many devices in one outlet can cause overheating and sparks.
4. Using damaged electrical cords: Damaged cords expose wires, creating a risk.
5. Playing near electrical substations: These areas are extremely dangerous and should be avoided.
6. contact with fallen power lines: Downed power lines can energize the ground around them.
7. Improper grounding: Lack of proper grounding can cause electrical current to flow through unintended paths.

Ways of Preventing Electrocution

Preventing electrocution involves adopting safety measures and being cautious around electricity.These include:

1. Keep electrical devices and sockets away from water.
2. Never touch electrical devices with wet hands.
3. Ensure cords and plugs are in good condition.
4. Avoid overloading electrical outlets.
5. Stay away from electrical substations and transformers.
6. Use safety devices like circuit breakers and fuses.
7. Regularly inspect electrical appliances for damage.

Lesson keywords

• Electrocution – Injury or death caused by electric shock.
• Conductor – Material that allows electricity to flow through it easily.
• Insulator – Material that does not allow electricity to flow through it easily.
• Outlet – A point in an electrical wiring system from which current is taken to supply devices.
• Circuit breaker – An automatic device for stopping the flow of current in an electric circuit as a safety measure.

Lesson Evaluation

To evaluate the learning, the teacher asks pupils to:

1. What is electrocution?
2. Name two causes of electrocution.
3. Give one way to prevent electrocution at home.
4. Why is it crucial to keep electrical devices away from water?
