Hmm.  If the disks really were "on fire", my preferred means of shutdown 
was the big red button by the door as I exited, PDQ.

Actually I did once have to do this.  I was "minding the shop" at lunch 
time on a sunny day.  As I looked into the machine room from the 
operations office I saw a cloud of smoke arising from the floor through 
one of the AC vents.  Dead stop - building alarm and get out.  It turned 
out that one of the AC units had started its steam generator and the 
blast was picking up dist mites, which showed up in a shaft of sunshine 
looking light smoke.<insert red face icon>  Most machines were at the 
far end of the room and it was only occasionally that that particular 
unit came on.  The fire brigade confirmed that it was the right action, 
but some of the users were less happy!
