They have a UL exhibit in Epcot where they show how they test TV screens. Using a ball bearing attached to a rope, they swing it into the CRT, if it breaks it doesn't pass(I assume anyway).
The tube can break, it just can't IMPLODE. As long as glass doesn't go flying out at the viewer, it passes the test.
What I find interesting is, they show lab techs in their nice white coats and safety shields over their faces. But what happens when a CRT explodes,Isn't mercury released into the room??
There is no mercury in a CRT...
Why are CRTs considered Universal waste now and not allowed in regular trash if its ok to just smash them?
The faceplate glass contains a lot of lead, for protection against X-ray emission. If crushed in a landfill, some portion of that lead leaches out into the groundwater.
