Throwing oneself on the neck of a CRT would be rather more efficient than throwing themselves on their sword.

Hello,

Read this piece:

Because of the strong vacuum within a CRT, they store a large amount of mechanical energy; they can implode very forcefully if the outer glass envelope is damaged. Most modern CRTs used in televisions and computer displays include a bonded, multi-layer faceplate that prevents implosion if the faceplate is damaged, but the bell of the CRT (back portions of the glass envelope) offers no such protection. Certain specialized CRTs (such as those used in oscilloscopes) do not even offer a bonded faceplate; these CRTs require an external plastic faceplate or other cover to render them implosion safe while in use. Before the use of bonded faceplates one of the hazards would be that a broken neck or envelope would cause the neck and electron gun to be propelled by atmosperic pressure at such a velocity that it would erupt through the face of the tube.

Unmounted CRTs should always be carried with its face, the heaviest part, down. Use both hands, and grasp the tube under the face, wrapping your hands around to the sides where the metal mounting frame is attached. Never carry a CRT by the neck! For added safety, carrying the tube in a closed, thick box or with a thick cloth wrapped around it (but not in such a way as to impair your grip on the tube) is a good idea; this will reduce the amount of flying debris should the tube break. Large tubes (over 19 inches) should be carried by two people. In general, you should treat the tube like a hand grenade, thinking that if you handle it carefully and keep your grip on it, there is no serious danger, but that it could cause a disaster if you drop it.

When handling or disposing of a CRT, you must take steps to avoid creating an implosion hazard for yourself or your trash removal service. The most simple and safe method to make the tube safe is to identify the small sealed glass nib at the far back of the tube (this may be obscured by the electrical connector) and then (while wearing safety glasses and gloves) filing a small nick across this and then to break it off using a pair of pliers. A loud sucking sound will be heard as the air enters the tube, filling the vacuum. Once the vacuum is filled, the tube is destroyed, but it cannot implode. One must be very cautious not to break the neck of the tube when it is evacuated since there is no plastic coating preventing shattering of the glass. High vacuum and high voltage can be dangerous.

Aye! -- Instrumentation tubes are the very devil when broken! -- I've a few 16' electrostatic 'roundies' salvaged from so-called 'Lecture Scopes' --- Having had the misfortune of breaking one -- the others are now stored in 0.75" plywood 'cartons' --- Even the (ubiquitous) 5" Tektronix CRTs are as miniature TNWs when disrupted -- Yes! Ok! -- a ridiculous exaggeration to be sure - though, was one standing near enough, he/she'd never know the difference!

It didn't seem all that long ago when some were saying, 'Soon TV will be just a flat screen you hang on your wall like a picture'!
