The chamber is not fully closed to relieve the pressure if present. The side towards the voltmeter is fully open, so if anything goes really bang, it should vent through there. The side towards the handle is solid, so should prevent any blast from heading that way.
I honestly think it is relatively safe as long as I don't touch the wires directly. And during discharge I never look at it, but away from it (too scary
) so if there is any debris, it will hit me in the back (I guess less important part than face...)
I am worried for the camera sometimes, but its a distance away and zoomed in, plus it has a UV filter on, which is just a replaceable layer that would have to break before anything reaches actual camera optics.

Thanks for suggestion, I will look for one...
