2. Safety & protection Just trying to make a work place safer

3. Electrical hazard awareness

4. What does hazard mean? Hazard means: • any potential or actual threat to the well being of people, machinery or environment Electrical hazard safety means: • taking precautions to identify and control electrical hazards

5. Why know about it? Because failing to take the necessary precautions can lead to: • injury or death • fire or property damage

6. What are the safety priorities? Electrical hazards exist in almost every workplace. Common causes of electrocution are: • making contact with overhead wires • undertaking maintenance on live equipment • working with damaged electrical equipment, such as extension leads, plugs and sockets • using equipment affected by rain or water ingress

7. How do you respond to electrical incidents? If you come across a person receiving an electric shock: • if possible, disconnect the electrical supply (switch?) • assess the situation – never put yourself at risk • take precautions to protect yourself and anyone else in the vicinity • apply the first aid principles (e.g. DRSABCD) • assess the injuries and move the casualty to a safe area if required • administer first aid if trained • seek urgent medical attention

9. Do you want to be a victim? You could be the victim if you: • don’t follow proper procedures around electricity • use electrical equipment improperly • use faulty electrical equipment

10. What are the types of injuries? • Burns • Shocks • Falls Keep safe Know how to control electrical hazards

11. What are the levels of effect of current?

12. What should you do in an electrical emergency? For low voltage electricity >50 V AC and 110 V DC • remove the source of electricity supply • commence CPR if trained • call the emergency number on site For high voltage electricity >1000 V • call the emergency number for your site • don’t go near the casualty • don’t touch the casualty or try to free them with anything

13. Should you report electrical incidents? • Electricity is invisible – this in itself makes it dangerous • It has great potential to seriously injure or kill • The company has a duty of care to its employees and contractors • Everyone is exposed to electrical hazards, not just electricians • Report all electrical shocks and near misses anyone can be exposed to electrical Hazards. they should receive electrical hazard training at the commencement of their Lab work or at workshop

14. Can you protect yourself from electricity? • Don’t wear metal objects • Turn power off • Wear appropriate clothing • Don’t touch live parts • Don’t install or repair electrical equipment • Use qualified personnel • Clean and dry leads and plugs before use

15. What are other safety measures? • Heed warning signs • Use the right equipment • Study the operation manual • Take care of extension leads • Use only approved extension lamps • Don’t pull on leads • Use residual current devices – RCDs • Use the proper fuses and circuit breakers

16. Regular safety inspections • are a part of YOUR job... • Electrical equipment should be checked each time before use for defects • If not tagged or the tag is out of date then report it and place it out of service

17. Should you be aware of powerlines? • Do you know if there are overhead powerlines on your site? • Do you know where they are located? • Do you know what the safe work clearance is? • Strict regulations are laid down to cover any work that may have to be performed close to overhead powerlines

18. What is a powerline corridor? MSI Regulation 5.28 defines a powerline corridor as the area under any overhead powerline that has not been properly isolated, and 10 metres either side of the powerline. • It is essential that these areas are respected. They are there for the safety of everyone • Do not store equipment, machinery, buildings or structures in powerline corridors • Do not construct, fabricate or maintain structures, buildings, machinery or equipment in powerline corridors LOOK UP AND LIVE

19. Can a powerline be approached safely? Up to and including to 33 kV • 2.3 m when passing underneath and 3 m when passing to the side Above 33 kV • 4 m when passing underneath and 6 m when passing to the side

20. Who can access sub-stations? • Only trained and authorised personnel may enter and work inside a sub-station • To enter a sub-station you must complete the sub-station entry training • Access is restricted for any cabinet with exposed energized parts All electrical work must to be recorded and entered into the Electrical Mines Record Book, and the Electrical Supervisor informed

21. Is this a problem? This is a small question for the audience…what is wrong with this connection…?

22. The key messages are… • The risk of electric shock from correctly installed and maintained power sources is negligible, provided that sensible precautions are taken by the operator and correct work procedures are followed • Ensure that the right person is carrying out electrical work – licensed versus competent • Electricity is essential but, improperly used, it can be DEADLY! To STAY ALIVE, you have to STAY ALERT

24. Thank you for a patient reading ..!! Yesterday is dead, tomorrow is uncertain, Today is a gift hence called present..!So please treat it that way..!! 
