How to release the vacuum in a CRT safely
I have a huge CRT that i need to stabalize so it can be removed and
trashed, ive left them in the garrage under vacuum and had one implode into 1000's of glass shards, is there a way to vent air in without breaking it all to pecies? -- Message posted using http://www.talkaboutelectronicequipm...ronics.repair/ More information at http://www.talkaboutelectronicequipment.com/faq.html |

The covering just in case what should be just a snmall hole should become a big hole - I've never experienced it but is a possibility. -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |

Ummm... put the CRT inside a few layers of plastic trash bag before releasing the vacuum perhaps? If it breaks, at least it doesn't make a huge mess. Managing Cathode Ray Tubes http://www.dtsc.ca.gov/HazardousWaste/upload/HWM_FS_CRT-EmergencyRegs.pdf I used to take the old CRT's out to the desert for target practice. (This was in the 1960's before ecology was invented). In most cases, I just punched a hole in the funnel area and did not catastrophically implode. So, with the supreme overconfidence of an 18 year old, I aim for the face of a large round CRT from about 5 meters away. Upon firing, I was showered with tiny particles of broken glass. I also saw the electron gun flying over my shoulder. Fortunately nobody was hurt. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Just run a triangular file across the neck near the base connector and tap with the file, using it like a hammer. The glass will crack and air will leak into the tube. This is the standard method of cracking and removing the old gun assembly prior to replacing the electron gun and restoring the vacumn. -- Best Regards: Baron. |

Tape a Crow Scarer tightly to the tube neck light and retire. It works for me! |

We let the vacuum out of old CRTs by puncturing the anode terminal with a sharp ice pick (actually a ground down Xcelite 'greenie') and a light tap. No broken glass and it feels cool when you put your finger over the anode terminal. Don't know about other tubes as all we have are Sonys. G² |

You shouldn't breath/inhale whatever is inside of those tubes.
