  4. Introduction to Electrical Safety • Electricity is a useful and powerful tool in our daily life. Today, electricity has become such an essential part of our life that it is difficult to imagine life without it.

  5. Electricity can be Dangerous..... • The danger of electricity: • Shock, burn or kill you • Damage sensitive devices

  6. Home Safety • To protect our home from electrical risks and hazards, we need to follow some home safety tips. DON'Toverload plugs because it can cause electrical fires. Neveruse an electrical appliance in a wet area. This will cause an electric shock

  7. Home Safety DON’T pull on the flex to remove a plug from the sockets. This will damage the insulations and cause a shock or an electrical fire Never allow children to play with outlets. Putting anything in electrical outlet may can shock or kill a person

  8. Home Safety Plugs should be pushed carefully all the way into the power points. Replace the socket outlet if the plug is loose in the socket or if it shows signs of damage.

  9. Home Safety

  10. Home Safety Always use plug protectors to stop small children from pushing things such as keys and pins into the power outlet. DON’T let leads from electrical equipment, such as toasters or kettles, trail across your cooker tops.

  11. Outdoor Safety • Sources of electricity hazards in the outdoors: • High voltage • Power lines • Electricity substations • Transformer boxes

  12. Outdoor Safety • To avoid accidents and protect yourself from electrical injuries, follow the next tips: Never bring ladders, long-handled tools or other items within 10 feet of an overhead power line. Never touch the underground power lines.

  13. Outdoor Safety Never play with transformers because they carry high voltages that can be deadly. Never fly kites or model airplanes near electric power lines.

  28. Electric Shock • An electrical shock is received when electrical current passes through the body. • We will get an electrical shock if a part of our body completes an electrical circuit by: • Touching a live wire and an electrical ground • Touching a live wire and another wire at a different voltage.

  29. Factors that determine the Severity of the 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

  30. How to Act in Electrical Emergency Situations • Downed Wire Get help right away. Stay away from all downed wires - even if there are no sparks. Do not touch anything, or anyone, that is touching a downed wire
