CASE STUDY 3 : CHAPTER 7- ELECTRICAL SAFETY

Introduction 

WELCOME TO SINCERLY . Well me SELVAKUMAR A/L SELVA SEKARAN. Today we are given the new task for Chapter 7 of Electrical Safety . 

WHAT IS ELECTRICITY?

Electricity is a natural phenomenon that occurs throughout nature and takes many different forms. In this tutorial we’ll focus on current electricity: the stuff that powers our electronic gadgets. Our goal is to understand how electricity flows from a power source through wires, lighting up LEDs, spinning motors, and powering our communication devices

DEFECTIVE INSULATION HAZARD :

IMPROPER GROUNDING HAZARD

1. Grounding is the process used to eliminate unwanted voltage. 
2.  A ground is a physical electrical connection to the earth
3. Electrical equipment must be properly grounded. 
4. Grounding reduces the risk of being shocked or electrocuted.
5. The ground pin safely returns leakage current to ground. 
6.  Never remove the ground pin.
7. Removing the ground pin removes an important safety feature. 

OVERLOAD HAZARDS

1. Overloaded circuits can cause fires.
2. Use proper circuit breakers
3. Never overload an outlet.
4. Do not use power strips or surge protectors on construction sites. 
5. Use a 3-way extension with a GFCI instead

WET CONDITION HAZARD

1. Wet conditions are hazardous. 
2.  Damaged insulation increases the hazard.
3. Always avoid using tools in wet locations.
4.  Water increases the risk of electric shock

PREVENTING MEASURES IN ELECTRICAL SAFETY

PROTECTION FROM DIRECT CONTACT

Protection from direct contact is 

which is electrical shock on touching directly a live conductor or cable.

 

PROTECTION FROM INDIRECT CONTACT

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 CIRCUIT AND EQUIPMENT

1. All electrical source
2. Place on each disconnecting means used to de-energize circuits
3. Attach lock to prevent operating 
4. Place tag with each lock

OVERLOAD WIRING BY USING THE RIGHT SIZE AND TYPE OF WIRE

 An electrical hazard exists when the wire is too small a gauge for the current it will carry. When a wire is too small for the current it is supposed to carry, the wire could overheat and cause a fire.The kind of metal used as a conductor can cause an electrical hazard. Special care needs to be taken with aluminum wire. Since it is more brittle than copper, aluminum wire can become loose and oxidize if not made properly, creating heat or arcing.

WHAT WILL HAPPEN IF ALL ABOVE IS NOT CONTROL? 

1. The number of injuries among electrical workers will be increase
2. It will been traumatized for the victims
3. Half of their body will been burn and died.
4. They also will lose some of their sensation.

  

CONCLUSION

Adequate electrical safety in health-care facilities can be achieved at moderate cost by combining a good power-distribution system, careful selection of welldesigned equipment, periodic testing of power systems and equipment, and a modest training program for medical personnel. Fortunately, the electricalsafety scare of the early 1970s has led to increased knowledge and greater safety for both patients and medical personnel.

Group Discussion : Chapter 6 - HIRARC

                                Group Discussion : Chapter 6- HIRARC



       Welcome to Sincerely. Well me SELVAKUMAR S/O SELVA SEKARAN .Today I'm going explain about HIRARC. HIRARC is as we know one of the Hazard Identification one of the Risk Control .HIRARC defination is compound word which is made up of three consecutive activities running one after the other. The activities consist of Hazard Indentification, Risk Assessment andRisk Control. Hazard indentification is the recognising of things which may cause injury or harm to a person.

                                   WHY NEED RISK CONTROL

        Risk Management is the process of identifying, analyzing and responding to risk factors   throughout the life of a project and in the best interests of its objectives. Proper risk management implies control of possible future events and is proactive rather than reactive.

                                              TYPE OF CONTROLS

ELIMINATION ACTION :-

Elimination of the hazard is not always achievable though it does totally remove the hazard and thereby eliminates the risk of exposure. An example of this would be that petrol station attendants in Ireland are no longer exposed to the risk of chronic lead poisoning following the removal of lead from petrol products sold at forecourts.

SUBSTITUTION ACTION :- 

Substituting the hazard may not remove all of the hazards associated with the process or activity and may introduce different hazards but the overall harm or health effects will be lessened. In laboratory research, toluene is now often used as a substitute for benzene. The solvent-properties of the two are similar but toluene is less toxic and is not categorised as a carcinogen although toluene can cause severe neurological harm.

ISOLATION ACTION :-

Isolating the hazard is achieved by restricting access to plant and equipment or in the case of substances locking them away under strict controls. When using certain chemicals then a fume cupboard can isolate the hazard from the person, similarly placing noisy equipment in a non-accessible enclosure or room isolates the hazard from the person(s).

ENGINEERING CONTROL :-

Engineering Controls involve redesigning a process to place a barrier between the person and the hazard or remove the hazard from the person, such as machinery guarding, proximity guarding, extraction systems or removing the operator to a remote location away from the hazard.

ADMINISTRATIVE CONTROLS ACTION :-

Administrative controls include adopting standard operating procedures or safe work practices or providing appropriate training, instruction or information to reduce the potential for harm and/or adverse health effects to person(s). Isolation and permit to work procedures are examples of administrative controls.

PERSONAL PROTECTIVE EQUIPMENT ACTION :-

Personal protective equipment (PPE) include gloves, glasses, earmuffs, aprons, safety footwear, dust masks which are designed to reduce exposure to the hazard. PPE is usually seen as the last line of defence and is usually used in conjunction with one or more of the other control measures. An example of the weakness of this control measure is that it is widely recognised that single-use dust masks cannot consistently achieve and maintain an effective facepiece-to-face seal, and cannot be adequately fit-tested and do not offer much, if any real protection against small particulates and may lead to a false sense of security and increase risk.

WHAT WILL HAPPEN  IF THE RISK IS NOT IN CONTROL? :-

There are some hazards with a recognised risk of harm, for example working at height, working with chemicals, machinery, and asbestos. Depending on the type of work you do, there may be other hazards that are relevant to your business.There are some hazards with a recognised risk of harm, for example working at height, working with chemicals, machinery, and asbestos. Depending on the type of work you do, there may be other hazards that are relevant to your business.Example : 

Task	Hazard	Risk
Delivering product to customers	Drivers work alone	May be unable to call for help if needed
	Drivers have to occasionally work long hours	Fatigue, short rest time between shifts
	Drivers are often in very congested traffic	Increased chance of collision
		Longer working hours
	Drivers have to lift boxes when delivering product	Injury to back from lifting, reaching, carrying, etc.

                                                CONCLUSION 

      The Conclusion that i get from this discussion is ,Hierarchy of control were use in order to minimize and control the most critical hazard that exist at the workplace. Furthermore, to ensure the safety culture can be implemented in an organization. This Act 1994 also protecting employers against risks to safety or health in connection with the activities of persons of work. Thank You.
