I worked for a while with underwater low voltage lighting @ UL. There were some experiments performed which showed that as little as 2V, 60 Hz across a person's submerged head could cause some rather severe symptoms, albeit not death.
I beleive that UL is a good source for research data in this area. As all of these good responses suggest, this is not an area for casual experimentation or assumption.

As long as the swimmer was completely in the pool and not touching anything grounded, he was OK, but when he grasped the handrail of the metal ladder to get out of the pool, it completed the circuit to ground and caused the electrocution. The important point is that the skin resistance was lowered so much by being completely immersed in water that even 12 volts became lethal. My recomendation is to contact your favorite NRTL Lab (UL/CSA/etc) directly and get a formal opinion.

Among other things the device generates a 12V DC voltage between the user's hand and his skin in other parts of his body. 1. What is the range of human body resistance expected ? 2. How much current is expected to flow ? 3. Are there medical (or other) regulations for this kind of situation? 4. What are the possible risks involved ? 5. Can you point me to standards documents (US,Europe..) thanks for your help moshe valdman
