Electrical hazard awareness

Electricity is a form of energy that results from the existence of charged particles (such as electrons or protons). It is a form of energy that we use to power machines, electrical and electronic devices. When charges do not move, electricity is called static electricity. When charges move, they are an electric current, sometimes called dynamic electricity.





Electrical hazard


Electricity Hazard:



A dangerous condition in which a worker could make electrical contact with an energized equipment or a conductor, and from which the person may suffer a shock injury.

Common causes of electrical hazards:

* Make contact with aerial cables.

* Performing maintenance on live equipment.

* Work with damaged electrical equipment, such as extension cords, plugs and plugs

* Use of equipment affected by rain or water ingress.

Electrical Injuries:


Basically there are two ways to injure electricity. One is by electric shock and the other is by electric arc.


An electric shock is the passage of electric current through the body. Electric contact can cause involuntary physical movements. Electric current can

* Puts you in touch with a high voltage conductor

* Make you lose your balance and fall

* Causes severe internal and external burns.

Effects of electric shock on the human body:

* The longer the exposure, the greater the danger of shock to the victim.

* Low voltage can be extremely dangerous because the degree of injury depends not only on the current, but also on the contact time with the circuit.

* Low voltage does not mean low risk.

* The electric arc is a release of energy caused by an electric arc. The flash causes an explosive expansion of air and metal.


Explosion procedures


* A wave of dangerous pressure
* A dangerous sound wave


* Extreme heat

* Extreme light.


These hazards can cause explosion injuries, lung injuries, broken eardrums, shrapnel wounds, severe burns and blindness. Electric arc injuries can also cause death.

High voltage leads to additional injuries such as:


* Violent muscle contractions: muscle contractions can cause bone fractures due to contractions or falls.

* Internal bleeding, destruction of tissues, nerves and muscles.


Precautions for electrical installations:



* Only the person who has a valid cable license / certificate of competence may perform electrical work and repair electrical equipment and install them on site.


* The electrical equipment and facilities will be maintained to avoid the danger of current conductors and to prevent fires that are caused by electrical causes such as short circuits, overheating, etc. The installation should not hamper the movement of men and materials.
* The grounding conductor of the wiring system must be made of copper or other corrosion resistant material. An additional ground connection must be made in appliances / equipment where the possibility of electric shock is high.


* The electrical fuses and / or circuit breakers installed in the circuits of the equipment for short-circuit protection must have the appropriate classification.


* Visually inspect all electrical equipment before use. Remove any equipment with frayed wires, missing ground teeth, etc. from service.

Tools and protective equipment.


Workers exposed to an electrical hazard should wear rubber mats, rubber gloves, flame resistant clothing and any other protective equipment required to protect against electric shock and burns. As part of daily work, electrical workers should always do it.

* Wear electric resistance shoes.

* Take off watches, rings, neck chains or other items that carry current
