  4. 1.1 Introduction to Electrical Safety • Electricity is a useful and powerful tool in our daily life. • Give examples of things that work on electricity. • as lamps, TVs, computers, mobile phones and DVD players.

  5. Examples of Equipment that work on electricity

  6. Dangers of Electricity

  7. 1.2 Home Safety DON'T overload plugs as this can cause electrical fire.

  8. 1.2 Home Safety Neveruse an electrical appliance in a wet area. This can cause an electric shock.

  9. 1.2 Home Safety DON’Tpull on the cable to remove a plug from the socket. This can damage the insulation and cause an electric shock or an electrical fire.

  10. 1.2 Home Safety Never allow children to play with outlets. Inserting conductors in an electrical outlet is dangerous and can cause shock, which can kill a person.

  11. 1.2 Home Safety Never allow children to play with outlets. Inserting conductors in an electrical outlet is dangerous and can cause shock, which can kill a person.

  12. 1.2 Home Safety Replacethe socket outlet if the plug is loose in the socket or if it shows signs of damage.

  13. 1.2 Home Safety DON’T make joints in a cable; replace it with one of adequate length.

  14. 1.2 Home Safety Always use plug protectors to stop small children from pushing things such as keys and pins into the power outlet.

  15. 1.3 Outdoor Safety • There are many outdoor electricity sources that can cause electricity hazards such as high voltage power lines, electricity substations and transformer boxes. • To avoid accidents and protect yourself from electrical injuries, follow the next tips:

  16. 1.3 Outdoor Safety • WHILE WORKING Neverbring ladders, long handled tools or other items within 10 feet of an overhead power line.

  17. 1.3 Outdoor Safety • WHILE WORKING Nevertouch the underground power lines.

  18. 1.3 Outdoor Safety • WHILE PLAYING Neverplay with transformers because they carry high voltages that can be deadly.

  19. 1.3 Outdoor Safety • WHILE PLAYING Neverfly kites or model airplanes near electric power lines.

  20. 1.3 Outdoor Safety • WHILE PLAYING DON'T play near live power lines. If you see a downed power line, stay as far away as possible and keep others away. DON'T climb trees that are near power lines. This can seriously injure you. DON'T play near electricity substations. They contain powerful electrical equipment that is dangerous.

  21. 1.4 Labs and workshop safety • Before you can use equipment and machines or attempt practical work in a workshop or a lab, you must understand basic safety rules. • These rules will help keeping you and others safe in the workshop. • Following safety rules will also prevent you and others from accidents, injuries as well as death. • To avoid accidents and injuries in the workshops and labs, follow the next safety rules and practices:

  22. 1.4 Lab and Workshop safety • Before conducting workshop tasks, be familiar with the location of:

  23. 1.4 Lab and Workshop safety

  24. 1.5 Safety and Accident Prevention • We have seen a number of safety signs that read, “Warning”, “Caution”, or “Danger”. • In the next few slides you will see the signs and what they mean.

  25. 1.5 Safety and Lab Prevention

  26. 1.6 Introduction to Electricity How does electricity come to your house?

  27. 1.6 Introduction to Electricity Electricity is generated from different sources such as power stations, wind turbines, water power, solar power and battery power.

  28. 1.6.1 Basic Electrical Terms

  29. 1.7 Electric Shock • An electrical shock is received when electrical current passes through the body. • You will get an electrical shock if part of your body completes an electrical circuit by:

  30. 1.7 Electric Shock Touching a live wire and the electrical ground. Touching a live wire and another wire at a different voltage.

  31. 1.7 Electric Shock • Severity of the shock depends on • Path of current through the body • Amount of current flowing through the body (amps) • Duration of the current flow through the body.

  32. 1.7 Electric Shock

  33. 1.8 How to act in emergency situations • Downed Wire

  34. 1.8 How to act in emergency situations • Downed Wire Touching a Vehicle

  35. 1.8 How to act in emergency situations • Electrical Fire

  36. 1.8 How to act in emergency situations • Electric Shock

  37. Almost Done • Any questions before we move on to activities?
