Here is some information I have:

1. It is important to minimize copper contamination of the skin;

2. One should always wash hands after handling copper or any other metals;

3. When zapping and covering copper contacts with salt-water dampened paper towels one should always discard the paper towel after the zapping session. This is because the bluish green tint on the paper towels after zapping contains copper chloride, which is toxic to humans.

Questions:

1. How dangerous is contact with leached copper chloride during zapping?

2. If our hands and/or feet are in contact with copper chloride that leaches into the paper towels (our hands and/or feet are touching the paper towels) is this dangerous? How dangerous?

3. Should we be changing the paper towels during a zapping session (for example we are zapping 7/20 7/20 7/20 or 14/20 14/20 14/20 etc)?

4. Please provide any additional information that may be related to questions that I have failed to ask but may be tangential to my other questions or generally pertinent to the underlying issues.

Many thanks,
