No toxic fumes in crt's. You can release the vaccuum by taking a small phillips, put it on the top of the neck of the tube and give it a tap with a hammer. You will hear a hissing sound which is air going INTO the tube. Once the hissing sound stops if you want you could break the neck to get the yoke off. Wrap it in a towel or blanket and smash with a bfh, recover copper, ferrite etc and dispose of rest in garbage.
