S3.10.8 For the adult
Electricity safety at home
Why must I never touch a switch with wet hands?
What this chapter teaches
Mains electricity can kill. Wet skin has a much lower resistance, so far more current passes through the body. A fuse is a thin wire in the live wire that melts when the current is too big, and a circuit breaker does the same job and can be reset.
Three questions to ask
There is no one right wording. Listen for the idea.
- Why is it more dangerous to touch a switch with wet hands?
- What does a fuse do, and why is it a thin wire?
- What is one place in your home where water and electricity are close, and what habit keeps it safe?
After the chapter, the learner can
- Explain why water and electricity are a dangerous mix
- Explain how a fuse protects a home circuit
What they copy into their notebook
Mains can kill. Wet skin lets far more current through, so keep hands dry. A fuse is a thin wire that melts when the current is too big. A circuit breaker can be reset.
