SLIDE FOR INTRODUCTION OF GROUP

Introduction of solenoid's group








Physical Hazard

THIS IS MY GROUP SLIDE FOR PHYSICAL HAZARD.
BUT ITS NOT MY SLIDE









17/3/2017 - CHAPTER 7 = ELECTRICAL SAFETY

πŸ˜† TODAY , I STUDY ABOUT ELECTRICAL SAFETY πŸ˜†



Our lecturer present new topic about 'ELECTRICAL SAFETY'..
 

Everybody hear with a lot of focus..
All student take attention while lecturer present new topic  about 'electrical safety'...


..THAT ALL TODAY ..
😎..THANK YOU..😎

13/1/2017 ,, Incident prevention ( presentation )

THIS IS POWERPOINT FROM GROUP RESISTOR
 
πŸ‘²NEXT PRESENTATION ABOUT 'INCIDENT PREVENTION'πŸ‘²



this is their group discussion. It is about Bird's loss causation model..

Case Study 3 : Chapter 7 - Electrical Safety

Introduction 

Assalamualaikum & have a nice day everyone. Today we are given the new task for Chapter 7. This group discussion consist of 3 members, I, Nur Hidayah Binti Zarapi, Puteri Shazmira Sofea & Nur Syafiqa Binti Ibrahim. 


 


WHAT IS ELECTRICITY?
Electricity is electrical energy or electrical power when its generated , supplied , or utilized .

 

DEFECTIVE INSULATION HAZARD :

IMPROPER GROUNDING HAZARD


 
 
  • Grounding is the process used to eliminate unwanted voltage. 
  •  A ground is a physical electrical connection to the earth
  • Electrical equipment must be properly grounded. 
  • Grounding reduces the risk of being shocked or electrocuted.
  •  
  •  
  • The ground pin safely returns leakage current to ground. 
  •  Never remove the ground pin.
  • Removing the ground pin removes an important safety feature. 
  •  You can get shocked! 
⇨ OVERLOAD HAZARD
  • Overloaded circuits can cause fires.
  • Use proper circuit breakers
  • Never overload an outlet.
  •  

  • Do not use power strips or surge protectors on construction sites. 
  • Use a 3-way extension with a GFCI instead.
WET CONDITION HAZARD
  • Wet conditions are hazardous. 
  •  Damaged insulation increases the hazard.
  • Always avoid using tools in wet locations.
  •  Water increases the risk of electric shock.
  •  
  • PREVENTING MEASURES IN ELECTRICAL SAFETY
    • PROTECTION FROM DIRECT CONTACT
    which is electrical shock on touching directly a live conductor or cable
     
     
    • PROTECTION FROM INDIRECT CONTACT
    which is occurs due to contact with a part which is connected to the electrical instalation , possibly due to damages in the appliance or insulation  , resulting in leakages of current .
     
     
     
    SAVE WORKING ENVIRONMENT
    LOCK OUT AND TAG OUT 
    • All electrical source
    • Place on each disconnecting means used to de-energize circuits
    • Attach lock to prevent operating 
    • Place tag with each lock
    •  
    •  
    •  
    • OVERLOAD WIRING BY USING THE RIGHT SIZE AND TYPE OF WIRE
     
     
     
    • Max.Ampere rating vs size for copper conductor
    • value are not more than 3 conductor in raceway or cable 


    WHAT WILL HAPPEN IF ALL ABOVE IS NOT CONTROL? 


    •  The number of injuries among electrical workers will be increase
     There will be no more electrical workers because they to afraid that they will die.

    • It will been traumatized for the victims
    • Half of their body will been burn and died.
    • They also will lose some of their sensation.






    Conclusion
    •Adequate electrical safety in health-care facilities and systems can be achieved at moderate costs by combining:
    1.Good power-distribution system
    2.Well designed equipment
    3.Periodic maintenance and testing of power systems and equipment
    4.Modest training program for medical personnel
