As usual, it depends. A plastic enclosure can collect charge. If you collect sufficient charge, it could arc and potentially damage static sensitive parts inside. That said, it should be reasonably safe if there are things to limit discharge voltage on the inputs and outputs of CMOS ICs (like caps on the supply).Will this be protected after it is installed?.Can it go bad?
I'm somewhat of a novice, but what do you mean by capacitors on the supply? Between the positive and negative terminals? It would be powered from a 12 volt wall wart.As usual, it depends.

When using CMOS logic, you need to have decoupling capacitors on the power supply so that switching outputs won't put spikes on the power rail. The inputs and outputs of CMOS devices have diodes that clamp them to the supply rails, so my thinking is that they would mitigate (not eliminate) ESD risk.I'm somewhat of a novice, but what do you mean by capacitors on the supply?
