I don't know how to connect your circuit and how to use the high voltage package. The 2 capacitors together have reached the withstand voltage of electrolytic capacitors.

Specific injury As long as you are connected to the capacitor standby circuit, it should not hurt people, because the capacity stored in the capacitor is limited. I was electrocuted by an electric cat myself. There should be no problem. The most direct way to call the police is to string a light bulb in the loop. If you have a loudspeaker music film, it would be better to get up.
