Electrical safety rules
The human body, especially wet skin, conducts electricity. The household mains voltage is 220 V and is very dangerous: current through the body clenches the muscles, can stop the heart and breathing and cause burns. So never experiment with the mains. Rules: do not touch bare or damaged-insulation wires; do not use electrical devices with wet hands or near water (bathroom, pool); unplug by the plug, not the cord; do not push pins, nails or other things into sockets; do not plug many high-power devices into one socket (overload heats the wire and can cause a fire); do not repair broken devices yourself – tell an adult. Stay at least 10 m away from a fallen power line and report it to the ambulance and electric services. Do not fly kites under power lines or climb electric poles. In homes a circuit breaker cuts the supply on excess current. Electricians use insulating gloves and tools. First aid: first switch off the current (breaker, plug); if that is impossible, push the wire away from the victim with a dry wooden or plastic object; never touch the victim before the power is off. Then call an ambulance (103); if the victim is not breathing and you are trained, begin rescue breaths and chest compressions.
Safety poster: list or draw 5 situations in your home or classroom that break electrical safety rules and write the correct version. Role-play “someone got a shock – what to do?” (switch off power, call 103). Safety: do not use any real electrical device, socket or wire for the role-play; use toys or drawings only.
