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.
