* For healthy workers, "brushing" contact with dry skin becomes dangerous above about 40 V. * For heavy contact from a full-hand grip, or through wet skin, open wounds, or watches or bracelets, voltages of 12 V or less must be considered dangerous. * For persons with medical conditions and implants such as heart pacemakers, any voltage could indeed be fatal. * Low-voltage sources capable of supplying currents above an amp or two can be dangerous because of possible sparks and molten metal if they are shorted out.

voltage isnt the problem it is the amperage through the body most say 100 milliampere is enough to kill Dc voltage can kill faster than AC

yes. but no one takes special precautions when handling a 1.5 V flashlight cell, nor even a 9 V radio battery, so that is obviously not true. thank you for your response.
