If a CRT is dropped, what is the most likely outcome?

When a cathode ray tube (CRT) is dropped, the most likely outcome is that it might implode, leading to potential damage to both workers and surrounding equipment. CRTs are constructed with a vacuum inside; when they are dropped or subjected to significant impact, the structural integrity of the glass can be compromised. If the glass cracks or shatters, the internal vacuum can cause the glass to implode, resulting in sharp shards being propelled outward at high speeds. This implosion can be extremely dangerous, posing a serious risk of injury to personnel nearby as well as damaging other equipment.

While it might be true that some CRTs are built with a level of durability, this does not negate the risks associated with dropping one. Going out of calibration or having the phosphor break loose are also possible outcomes of impact, but they are less immediate threats in terms of safety compared to the risk of implosion. Therefore, the catastrophic nature of an implosion, along with its implications for safety, makes it the most likely and concerning outcome when a CRT is dropped.
