Power steering failure ?

[whopwop]

Hi,
while parking the car this afternoon there was a puff of smoke/steam from out of the driver side wheel arch and the power steering is gone.
It sounds to me like the power steering hose has burst. ????
I am no mechanic , but i drove the car home slowly which is only a few miles with no other consequences, ie/ no lights came on, no battery warning lights etc.
Has this happened to anyone here before and is it safe to drive the car to the garage or should it be transported ??
Thanks in advance.
Mark
