Ch. 2 Sec. 6 Electrical Safety

short circuit

• connection that allows current to take path of least resistance

Electric Shocks• Severity depends on

current (amps)• Currents > 0.2 amps

can cause burns & stop your heart !!!!

Circuit = electrically grounded when charges able to flow directly from circuit into Earth in case of short circuit

third prong• round part of plug

• connects metal shell of appliance to ground wire of bldg

• device that has thin strip of metal that melts if too much current flows thru it

• protects devices plugged into it

fuse

Circuit breaker= safety device that uses electromagnet to shut off circuit when current gets too high

Electric Shock First Aid 1. Remove the victim from the

source of electricity before you touch him. Either turn off the master switch to disconnect the power, or use a nonmetal, dry object such as a stick to pull the wire or electrical source away from the victim's body.

2. If he is not breathing, begin rescue breathing immediately; a victim whose heart has stopped breathing needs CPR.

3. If the person is unconscious, but is breathing and has a heartbeat, you should place him in the recovery position and monitor his breathing and heart rate until medical help arrives.

Victims of Electric Shock

Electric shock injury to the foot

Electric shock injury to the hand

Electric shock burns due to current flow through metal framed glasses.

Remember, electricity can

be dangerous!!!
