CASE STUDY 3

ELECTRICAL SAFETY

 Assalamualaikum and have a nice day everyone, today we are given the new task for chapter 7. This group discussion consist of 3 members, Siti Asmadiana binti Saiful Amran , Solehah binti Johari and Nurul Najihah binti Rosli and we are from the Solenoid's group.😁

                         

 WHAT IS ELECTRICITY
 A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.

 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
