There is nothing in a CRT monitor which is any more prone to catch
fire than in a computer itself.
CRT monitors have no more than 24 volts DC present in any circuit
element, with the exception of the high voltage accelerating potential
circuit. Now, THAT circuit may well have 12 to 25 kilovolts of DC, but will
be so current-limited (a few microamperes), that one would be hard-pressed
to start a fire by intentionally removing the anode wire and arcing it between
ground and a piece of paper!
What else is there _different_ in a CRT that will burn? The
deflection yoke? No way!
Now, let's talk about a REAL VDT problem: I hear that VDT's cause
an unhealthy buildup of negative phlogiston in the atmosphere... :-)
