1. Do not use a grounding mat or pads while doing contact. This creates a path to ground for the electricity to leave your body. Also, do not ever do 2 contact treatments at once, using 2 generators. This has the same bad effect.
2. Never even lay on a grounding mat near electrical equipment you become like an antenna for that energy to go into the ground through your body. Grounding mats are good at least 4meter away from electrical sockets then your fine.
