CRTs contain Cadmium , Barium, Lead and Mercury. PCBs, about the same, especially depending on specifics and application. All of which are HIGHLY poisonous to humans.

If you don't know or are not educated yourself; You must be careful or you will harm yourself.

I believe they didn't completely phase out using these materials til 2010 and before. Be careful

They were phased out in around 72... out side of lead and the lead used was very very small only found in the glass near the neck and barium withc was only used to flush out a CRT of loose glass and other gasses when replacing the tube. You don't know what you are talking about, I used to replace the tubes on CRTs regularly witch included heating the glass up with a torch. the only harmful parts are the stuff found on/in the PCB and the glass if shattered, maybe the fly back if you go poking it wile it's powered on. And no the lead is not for blocking X rays, its for deflection. assuming you are not dealing with a pre 72ish B&W CRT, those are the ones with all the harmful crap in them. Next thing you're going to say PSUs have 10s of 1000s of volts in them when powered off.

Looks like Thomas Electronics still uses barium https://www.thomaselectronics.com/crt-r ... endations/ and says it's common practice. Barium Oxide, BaO, baria, is harmful to skin and can cause irritation if swallowed (I doubt anyone is swallowing bits of broken CRTs though). :P Large enough quantities can lead to death.

I misspoke when I said phosphorous, it's phosphors which contain any number of compounds:
https://www.phosphor-technology.com/crt-phosphors/ not that phosphorus doesn't have is own health risks in quantity.

So...the point isn't that you can't possibly handle a CRT or dismantle it or even break it. You just have to be aware that there are some risks, however slight. Also, Lostinlodos can probably expound on this better than I can, having this site hosted by a business, there's probably a level of liability involved that they don't want to be responsible for. Just because I have handled CRTs and removed everything from a bulb and broken the vacuum doesn't mean Boardsort wants a conversation about it (at the very least without acknowledging there are risks) cause there's inevitably someone who will read it and blame Boardsort after they go around bashing in CRTs carelessly and end up finding one that implodes just right to throw glass back at them or who decides to break them all in their basement and when they go to clean up, breath all the dust with various compounds for lack of a respirator.

Again, if you don't know what you're doing or how to handle certain things, anything can be dangerous.

This thread has gone on a tangent. My original question was about LCDs. Why are we talking about CRTs?
