CORRECT!
, Four man types of electrical injuries - ANSWER Electrocution, electrical shock, burns,
falls
Factors that affect the severity of injury from electrical shock - ANSWER Amount,
duration, and path of current, condition of body
1mA - ANSWER Faint tingle
Below 1 mA - ANSWER Generally not perceptible
5mA - ANSWER Slight shock felt; not painful but disturbing
6-25mA (women) - ANSWER Painful shock, loss of muscular control, cannot let go, can
be thrown away from circuit
9-30mA (men) - ANSWER Painful shock, loss of muscular control, cannot let go, can be
thrown away from circuit
50-150mA - ANSWER Extreme pain, respiratory arrest, severe muscular contractions,
death is possible
1.0-4.3 Amps - ANSWER Rhythmic pumping action of the heart ceases, muscular
contraction and nerve damage occur, death likely
10 Amps - ANSWER Cardiac arrest and severe burns occur. Death is probable.
15 Amps - ANSWER Lowest over current at which a typical fuse or circuit breaker
opens a circuit.
Temperatures that can be reached in an arc blast - ANSWER 35,000 degrees F
3 types of burners caused by electricity - ANSWER Electrical burns, arc burns, thermal
contact burns
First action when co-worker is getting shocked by electricity - ANSWER Shut off the
current or power
