Hm. I'd be more worried about flying glass shards hitting a major 
artery. Death by massive blood loss can't be much fun, and AIUI survival 
rates are pretty slim even with prompt first aid. Medium-low likelihood, 
but very, *very* high risk.

If I was doing this, I'd be using a nice, big metal face-shield (similar 
to those used for welding), REALLY THICK clothing and similarly thick 
gloves. At least then any glass shards would have to be pretty damn huge 
(and flying with considerable energy at short distance) to do any major 
damage.

Though that said -- don't most CRTs have an anti-implosion band, which 
is intended to stop the glass from spreading out? Or are these CRTs too 
old (or small?) for that?

Though AIUI blowing out a CRT from the front would involve significant 
force... along the lines of BB guns or rifles, not small tools dropped 
on the tube face... I know the DG7/32 scope tube in my spares box has a 
decently thick face vs. the neck thickness (looks to be a good 1cm 
thick), and that's only a 7cm round-face tube. I'd imagine a 14in or 
17in raster-scan tube would have a similarly thick face plate, if not 
thicker.
