Safety glass -- how necessary?

definately safer... no question about it.

How much safer? I think alot safer in many situations. So if it's just 1% safer is it worth the trouble to get it re-laminated? I guess it depends on how much you value any extra amount of extra safety.

I am 100% certain there is a product available to re-laminate. I will eventually figure out what that is whether I get help from those who know here or not.

Somebody here definately knows what product is available and where to get it.

Wow, that implosion photo is scary.

The safety glass blew out, too, as David noted. But who knows -- had it not been there, perhaps the lady would have been injured more seriously. The safety glass might have slowed down the CRT shards, broken them into smaller pieces, etc.

You have to wonder what happened right before the implosion. A frying sound, followed by a loud pop. I wonder if an electrolytic capacitor blew up. If a can electrolytic blew its top, or took off like a little rocket, I could imagine that cracking the neck of a CRT.

I have never had a radio start on fire, but I have had a couple of electrolytics that popped with an impressive firecracker noise.

In my irresponsible teen years, we used to take our .22 rifles to the town dump, shooting at rats and every glass item in sight. We wrecked plenty of old radios and appliances, but we never managed to blow up a TV. Thank God there is no videotape of me on those excursions, shooting up old console radios that I would now gladly rescue and restore.

Back in the mid 70's we had a B&W TV that we were tossing. Probably something we'd restore today, but back then just an old POS... Cheap wood cabinet with fake wood grain plastic "paper" over it. Anyway, the town wanted us to let the vacuum out of the CRTs, to safe it for the trash men. A few other CRTs were easy, just break off the little glass seal in the middle of the tube pins in back. But one CRT, 21 incher or so, had a bakelite tube plug covering over the seal, and thus inaccessable. So I decided to put the TV at the curb, without the chassis and back, and standing about 30 feet away, toss rocks to try to bust the neck off. I missed the neck, but scored a hit right in the big part of the tube. KABLAMM! Glass flying all over the place, and it turned out to be wise to stand as far away as I did...

An about-1964 23" B&W console made a nice Melluva Hess when I unloaded a clipfull of 115 grain 9MikeMike from my Uzi at it....But I have shot .22s at rectangular color sets, if you aim at the corners, sometimes they just spiderweb the tube...

Never purposely imploded a crt older than mid 70s. By then they mostly all had implosion prevention built-in.

What does 'integral implosion protection' actually mean?

All they did was to put a tensioned metal rimband around the face of the picture tube. This band is sometimes combined with mounting ears in later tubes. It's purpose is to hold the edges of the face tight, so that if the tube does implode, it's more likely to crush in on itself, rather than spraying glass all about.

Several years ago, I was carrying a 23" color tube to the van to haul off. The thing slipped out of my hand and I hauled butt as it was falling. It hit the concrete on the corner and KA-BOOM! My mother heard the noise and came running out of the house to make sure I was OK. We spent 30 minutes sweeping up tiny pieces of glass from the driveway.

Well, I was a little younger and moved a little faster back then. I was lucky that I didn't meet up with flying glass. I will say that tube didn't make quite the bang that a 21" non-implosion protected tube did when I threw it away.

I also had a friend that had a "near miss" when a tube imploded. He had an early '80's Sylvania console that used the inline tri-pot tube. That tube had mounting ears on it and no metal degaussing shield. He tried to replace that tube with one of the Zenith tubes of the era that had no mounting ears and used a degaussing shield. He fabricated some sort of metal band to hold the Zenith tube in the Sylvania case. When he sat the TV in it's normal, upright position - BOOM! I guess the band that he fabricated put too much pressure on the tube. He was not hurt; but, he had a mess to clean up.

That's valuable info!

Thank goodness nobody was hurt.
