Safety Around Low Level Electricity:

We will be working with between 3 and 9 volts of electricity. When used properly and directions are followed, this is very safe.  Generally 3-9v of electricity is not enough to cause permanent bodily harm, but it is enough to cause overheated wires if a short circuit is accidentally caused. Minor 1st or even 2nd degree burns can result if overheated metal is touched (like a blister). It could also cause melted plastic insulation or casings, and even catch fire to any combustible materials nearby (all rare occurrences) but nevertheless, something you need to be aware of.
