The hoses will pop-off before any damage is done due to preassure. The preassure
will also leak out in time so there's no danger there either.

Depends on the compressor.

Don't know. There was a thread about greasing them a while back though:

As seen in the previous answer, yes. Better yet is to use the hard plastic tube
that comes with some Technic sets:

And that's actually the second best use of those pieces, the best being as Flex
System Hose :) I actually sort them into my pneumatic hose-bucket.

C.S. Soh's Lego page - Where air is power.
Temporarily unavailible due to heavy load at the moment though :(
