I'm using the touch library to create a set of input signals to control a light sculpture. The metal inputs are large 1/8" steel plates. The setup works very well and can get some good response to how much of the metal input is being touched. The devices are going to be deployed in a very dry environment and I'm worried about static discharge. In order to get to the devices you have to climb up a ladder and I'm planning on having a grounding plate be one of the rungs which will help to ground participants.

Does anyone have advice on if I should be protecting the teensy inputs to protect against that kind of shock directly?
