Never heard of needing to open a PDF in sandbox mode, but it makes sense cause of potential malicious content so I looked up if Chrome does it by default with it's viewer. It does, as does Firefox and Safari so that covers most browsers.
PDF in the spec contains an insane amount of stuff which could be exploited. But every reader other than the Adobe one leaves out most of the spec.
So I wouldn't be that worried about opening a random PDF in a browser. But I would be maybe worried about opening one in a desktop app written in an unsafe language.
