    Never. However, one can accidentally sit on them.

    Correct. Even if all hell goes wrong, the tube may get hot, but not explode. Vacuum tube…void of air.

    Read on this and recall it is impossible. It's a vacuum, so there is no air or gaseous material inside to expand and burst the glass vessel. If anything it would have to implode but that would require a set of circumstances outside the tube that would not (or cannot) exist under ordinary conditions.

    The biggest danger with tubes is you drop it and cut yourself on broken glass or breath in dust from heavy metals they use on the internals. I believe some older DHT's also could contain Thorium, which is radioactive.

    I've never experienced a tube explode in over 60 yrs of using them. The only time they have catastrophic failure of the glass is when dropped, struck with a solid object such as a hammer, or thermally shocked like pouring ice water over a hot tube. As the wise men say, don't do that.

    First really big tubes I used were 811A triodes and 866 mercury vapor rectifiers for an amateur radio linear amplifier.

    Maybe if you make a really big vacuum tube Christmas tree
