High voltage capacitor may catastrophically fail when subjected tovoltages or currents beyond their ratin losive rupture than rectangular cases due to n inability to easily expand under
However, the stored energy within a capacitor becomes a lurking threat. While electrical capacitors have long been recognized in many trades as a potential electrical hazard, historically the National Fire Protection Association (NFPA) 70E standards for electrical safety did not say much about them.
Some doesn't. If properly abused, that capacitor would make quite a bang and mess. It is unlikely that the bang would kill you even if you were a couple of feet away, but you can't rely on that, and it could certainly hurt you pretty severly. A serious injury like loosing one or both eyes isn't far fetched at all.
Disc capacitors tend to crack open if overloaded-the polarity does not matter. Unless you overvoltage them or reverse voltage them or have a high current ripple in the DC power line beyond the capacitors rating they are safe to use. I have had them (electrolytic can capacitors) explode in my face due to being installed in reverse.
