Don't do it, it's not safe.

In case you're allowed to boot from an external medium, this still won't be
secure. Because you have no control over the hardware built into the computer,
a keylogger could read your input (read: passphrase), and somebody else with
remote access could copy your secret key.

After all, it boils down to what your thread model is, and how much unsecurity
you can live with. If your data is crucial: don't do it.
