Why immersion in water can be fatal with very low voltages

1	Immersion wets the skin very effectively and greatly lowers skin resistance per unit area
2	Contact area is a large percentage of the entire body surface area
3	Electric current may also enter the body through mucous membranes, such as the mouth and throat
4	The human body is very sensitive to electricity. Very small amounts of current can cause loss of ability to swim, respiratory arrest, and cardiac arrest
