High amperages are really only dangerous (in terms of electrocution) with higher voltages. As voltages get low enough, our bodies' resistance means that there won't be enough current passing through you to hurt you. The dryness of the contact point makes a big difference (several orders of magnitude), but even with wet hands, it is pretty much impossible to hurt yourself with < 12 volts. The risks with low voltages and high amperages are from shorts causing rapid heating.
