When a fluorescent tube loses vacuum, does it release mercury? « on: April 04, 2022, 04:21:31 AM » Author: WorldwideHIDCollectorUSA
After knowing that some fluorescent tubes lose vacuum when they go EOL, I wonder if they release any mercury vapor and any buffer gases like argon into the surrounding environment just like they would if they get broken.

I would say so?, if air has got in somewhere then the contents of the tube can get out the same way, although I wouldn’t say it’s in any high amount to be dangerous? I had an 11 watt CFL in my pocket a couple of weeks ago, and knelt down to pick something up, breaking the tube in my pocket in the process! Didn’t get any adverse effects from it though

The pressure in the lamp is very low, so when the lamp losing vacuum, nothing escape, but air leaks in instead.

Quote from: Rommie on April 04, 2022, 08:08:48 AM The amount in a single lamp isn't really worth worrying about. If you smash a pallet-load of lamps then yes, but one tube or CFL isn't going to kill you. I was more concerned about the lamp than my own health!  , I was gutted I’d broke a GE Biax, something I now consider as ‘rare’!

But the amalgam capsule inside the lamp, once broken, can create dangerous metal leaks

The amalgam pellet would have to be leached by some water or so. Otherwise the amalgams generally tend to attract the mercury back, so I would not be affraid that much
