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
