Some Definitions What is the electrical shock, How does it
happen??!!! Danger of Electrical Shock Safety form it Helping Summary
Content
Voltage is the force that causes the current. Current is the amount of electricity that is
flowing. Resistance slows down or stops the flow of
current. Ground is a physical connection to the earth,
which is at zero volts and is a sink of leakage current
A neutral is the return path back to the sourceCircuit--complete path of the current
What is about
Occurs when part of the body completes a circuit between of different voltages or between an electrical source and a ground, which cause current flow in the body
When that happens, you might feel a tingling sensation.
Definitions Electrical shock
Touch the metal parts of electric tools and machines may become energized, when the Grounded is disconnected
Water (Hand wet)
How does it happen???!!
How does it happen???!!(Cont.)
How does it happen???!!(Cont.)
Severity of the shock depends on:◦ Path of current through the body◦ Amount of current flowing through the body
(amps)◦ Duration of the shocking current through the
body,
Severity of the shock
There are four main types of electrical injuries: Direct: Electrocution or death due to electrical shock Effect on nerves , brain and sometime STOP of Heart (STOPED heartbeat) Burns Indirect – Falls Workers in elevated locations who
experience a shock may fall, resulting in serious injury or death
Danger of Electrical Shock(effect)
Test the earth leakage circuit breaker Be Sure all of wires isolated Use screwdriver tester and Voltmeter Don't touch any metal parts of electrical
devices when it is energized(TurnON) Be sure the Ground is connected to device,
and DON’T never remove it. Must have a isolated and not wet shoes. Don’t plug in/out in wet hand Condition. Don’t Touch any two or more wires.
Safety
Call for help immediately. Often, a victim is unable to pull away from the current source.Use dry rod wood and isolator from the Ground Stop the flow of electricity in the victim’s body — disconnect or de-energize the circuit. Do not try to remove the victim from the current source. Touching the victim could
cause you to be shocked as well.
Helping an Electrical Shock Victim
Is very important in the Hospital Revive heart by using it
Self-defense Is used by policeman
Finally, Some benefits of it
Electrical shock: electrical current passes through the body.
To prevent it Don’t be wetMust be have shoesDon’t touch the electrical wireBe sure form the Ground is connectedDon’t persuade yourself know when you
unknownDON’T trust with everybody say I TURN OFF the
source, check and see by yourself.
