2. Electric Shock
 An electric shock occurs when a person comes into contact
with an electrical energy source. Electrical energy flows
through a portion of the body causing a shock. Exposure
to electrical energy may result in no injury at all or may result
in devastating damage or death

4. Electrical Prevention
 Inspect electric cords for fraying. ...
 Do not plug too many things into the
same outlet. ...
 Replace all older two-pronged outlets. ...
 Insert plastic safety caps in all
unused electrical outlets if small children
are in the home.

6. Earthing / Grounding
 Earthing: The process of transferring the immediate
discharge of the electrical energy directly to the earth
by the help of the low resistance wire is known as the
electrical earthing. The electrical earthing is done by
connecting the non-current carrying part of the equipment or
neutral of supply system to the ground.
 Grounding: The process of connecting a circuit or system to
an electrical ground to carry current safely away in the event
of an electrical surge or an internal fault that connects a high
voltage source to the exterior of the device.
