Shock Effects from the world's largest aerospace company. They wish to remain nameless, so I will give them the code name of a Dr. Seuss character - Gerald McBoeing-Boeing.

Current Range and Reaction:
<1 mA - Generally not perceptible.
1 mA - Faint Tingle.
5 mA - Slight shock felt, not painful but disturbing. Most people can let go.
6-25 mA - (Women) Painful Shock, loss of muscular control. Range in which you can't let go occurs.
9-30 mA - (Men) Individual cannot let go but can be thrown away from circuit of extensor muscles are stimulated (by the shock itself)
50-150 mA - Extreme pain, respiratory arrest, severe muscular contractions. Death possible.
1,000-4,300 mA - Rhythmic pumping action of the heart ceases. Muscular contraction and nerve damage occur. Death likely.
10,000 mA - Cardiac arrest and severe burns occur. Death probable.
15,000 mA - Lowest overcurrent in which a 15A fuse or circuit breaker will open.
