Even if you charged that capacitor to 250V it still wouldn't be dangerous, but it would give you a shock - but 9V is far too low to even give you a shock.
In most cases I would agree with Nigel, but there are some instances where it could be very dangerous. All I can really say is use common sense, and don't be stupid
For example, if a child accidentally swallows it, or if there is a path of little resistance into your body tissue (an open wound). Ask any doctor and I'm sure they'd be able to give you many more possible ways it could hurt you.
That's the thing about electronics--if you really want to be 100% safe, you need to treat everything like it could be dangerous. Think about what you're doing BEFORE you do it and you should be fine. I always expect the worst, which is probably the only reason I'm still alive

Hahaha I think you misunderstood my post. I wasn't really disagreeing with you that a 9 volt shock can't cause harm in most cases. I was simply saying that if you do something stupid, anything can be dangerous. Especially when it comes to electronics. For the most part, I agree with what you said. I'm just saying to treat everything like it could be dangerous.
