What is electrical Shock?
A sensation and muscular spasm when electric current passes
through the body.
What is a GFCI?
Ground Fault Circuit Interrupter (automatically shut's off electrical
flow in the event of an overload)
TS Transformers
Open: T doesn't generate output V
Short: could be partial which would then change number of coils so
Ep would change or Es
What is voltage
Potential of electric energy; pressure of electrons pushing away from
each other.
Current is defined as __________________________.
a flow of electric charge
What are some factors affecting shock?
Amount of current, path of current, amount of body resistance, and
length of time current flows in body
, What is not a primary factor in severity of an electric shock?
The general health of the victim.
Ways to prevent shock?
Isolate, insulate & ground
What is the minimum AC current required to cause severe muscle
contractions?
12 mA
How much more DC is required to freeze the body than AC?
5 times more
What types of burns are there?
Electrical burns, arc burns, and thermal contact burns
Electrical burns are what?
Electrical current flowing through tissue or bones
Arc burns are what?
Electrical current flowing through tissue or bones
Thermal contact burns are what?
When skin comes in contact with hot surfaces of overheated electrical
conductors
Factors of electrical accidents
Unsafe equipment, unsafe environment, and unsafe work practices
What should you do first if someone has been shocked?
