LOW VOLTAGE DOES NOT IMPLY LOW HAZARD!
A severe shock can cause considerably
more damage to the body than is visible. For example, a person may suffer
internal hemorrhages and destruction of tissues, nerves, and muscles. In
addition, shock is often only the beginning in a chain of events. The final
injury may well be from a fall, cuts, burns, or broken bones.
Effects of Electric Current in the Human Body|
Milliampere||Perception level. Just a faint tingle.|
5 Milliamperes||Slight shock felt; not painful but disturbing.|
Average individual can let go. However, strong involuntary reactions to
shocks in this range can lead to injuries.
6-25 Milliamperes (women)||Painful shock, muscular control is
|9-30 Milliamperes (men)||
This is called the freezing current or "let-go" range.|
50-150 Milliamperes||Extreme pain, respiratory arrest, severe
Individual cannot let go. Death is possible.
1,000-4,300 Milliamperes||Ventricular fibrillation. (The rhythmic
pumping action of the heart ceases.) Muscular contraction and nerve
damage occur. Death is most likely.|
10,000-Milliamperes||Cardiac arrest, severe burns and probable
