Electrical safety
Fuses, earthing, water and damaged cables: staying safe around electricity.
Planned. This module is part of the plan and is not written yet.
Why it matters
Damaged cables and wet hands near sockets cause shocks and fires in homes. Knowing what fuses and earthing do, and what to do when something goes wrong, keeps families safe.

Inside the module.
4 lessons in order, about 45 minutes in all, then a short test. Learners go at their own pace; the minutes are a guide, not a timetable.
Draft outline · in review
Lesson 1: How electricity hurts
Why current through the body is dangerous, and why water makes it worse.
Explain10 min, from minute 0
Lesson 2: Fuses, breakers and earthing
How each one cuts the power or gives a fault a safe path to the ground.
Explain15 min, from minute 10
Lesson 3: Spot the danger
Find the hazards in a picture of a home: overloaded sockets, frayed cables, water near plugs.
Investigate10 min, from minute 25
Lesson 4: In an emergency
What to do if someone gets a shock: power off first, never touch them, get help.
Discussion10 min, from minute 35
End-of-module test
Explain how fuses, circuit breakers and earthing protect people, and identify electrical dangers at home and the right response.
Mastered at 85% or more. Retake it until you pass; nothing is lost, and each try gives feedback.
Already know it? A Challenge Test (planned) clears the whole module: 90% overall, no objective below 75%.
