Fairly minimal unless you have a masters degree in incompetence. The
capacitor is the dangerous bit when working inside as it stores a high
voltage charge with quite a bit of energy, a dangerous combination.
You can discharge this using a simple tool but leaving it switched off
for a day before playing inside also works well.
