That's the worst time for glassware to break . . .I would rather it die valiantly in a destructive distillation than before its even been used.
If you have all the pieces and access to a good glassblower, he/she may be able to fix it for you.

I got an electric shock from my heating mantle today. Not serious though, just enough to startle me. I didn't even touch any metal parts, just the
glass wool with both hands as I was feeling whether it started getting warm. It must be all the moisture in my unheated lab, it condenses inside the
glass wool and together with traces of salts from spills and aerosols it becomes partially conductive.

Nasty, GC!
Yesterday I was washing glassware. A very cheap Erlenmeyer falls on the floor, and is fine. Phew.
Today, I was washing glassware. A condenser falls on the floor, and breaks. Screw!

I agree! I once had a boiling, concentrated solution of potassium chlorate in a large beaker heating over a Bunsen flame. Two minutes later, a large
purple flame is observed as the beaker breaks and the liquid (and glass) is sprayed everywhere!:/

It depand on the quality of the glassware , bomex will break only with heating , pyrex classic could withstand boiling water and then be dropped in
ice. This is why I buy only pyrex classic beaker/flask and for the test tube pyrex vista.

I never asked for this.

Oh, trust me, it's not fine anymore. Mark it as "potentially failing".
Regarding the swearing, I unleash my fury when shit happens, but otherwise I'm quite calm and dislike swearing.

The other day, when I was cleaning up my stuff from chromium (VI) residue, I was using sodium metabisulfite. The wet solid fumed so much I couldn't
breathe well for 10 minutes afterwards. It made my cough much worse. I hate SO<sub>2</sub>. From now on I'm going to wear a respirator
when working with sulfites or just use sodium thiosulfate.

Nasty!
Today I was dumping a waste lead acetate solution down the toilet and forgot there was a stirbar in it. . .so I attached a magnet to some acrylic rod
and went fishing down the lavatorium!

Lead down the toilet? How much? You should rather precipitate it and then dispose of it, or recycle it.
Also, I have forgotten my stirbar at least twice when pouring something into the sink. Unscrewing the trap beneath it and getting it out is pretty
nasty work...

I usually do, but it was only a very dilute (probably less than 0.01M) and had a volume of about 30ml. So not much lead was actually present, and,
where I live, proper hazardous waste disposal costs an arm and a leg.

Are you sure? The least you could have done was to react the lead salt with baking soda to form an insoluble carbonate. I do that whenever I deal with
iron salts (after staining multiple things, including my roof ).
If you're wondering how I stained my roof, I used to have my lab upstairs and I like to keep the window open in the summer. Clumsy as I am, I knocked
over a large jar of iron III acetate and it spilled all over the roof. Somehow the jar didn't break, but the solution quickly evaporated and the iron
deposited onto my roof. To this day, I'm not sure how to get rid of the stain. I guess you could call that a bad day in the lab.
Just gravity filter out the carbonate and bury it somewhere far, far away. Although lead carbonate is insoluble, it will react with acids and become
soluble again over time, so even pouring lead carbonate down the toilet is not a good idea either.
The proper disposal method IIRC is to bubble H2S into a solution with dissolved lead, but considering you didn't even do the bare minimum, I don't
think you'll go through that much trouble.

Its very irresponsible to dump ANY heavy metal waste down the drain. Always precipitate it and save it in a polybottle, either as "lead waste" or as
"mixed metal waste". The advantage of collecting it separately is that it is re-usable with less hassle than having to separate the elements again.
Same with solvent waste, although you can't always recycle this efficiently (e.g. hexane-ethyl acetate waste, boiling points are too close for
anything resembling a trivial separation).
I was trying to break up an oil that had solidified in a rbf the other day at work, and ended up putting the spatula right through the wall of the
flask, despite not being heavy handed with it. Thankfully my hand was underneath the produced hole, allowing me to catch my valuable product! I was
left unscathed thankfully, and my compound was recovered in full.

As aforementioned, only very small amounts of lead ions were actually present, yet from today forwards I shall do as you say and collect all hazardous
waste. But, alas, what should I do with it when it's full?

I collect all hazardous metal waste in a single bottle. This bottle contains solutions of lead, cadmium, nickel, silver, mercury, tellurium and quite
a few others. When it is full, I bring it to a municipal waste processing facility and I tell that it is photography darkroom waste. The bottle is
labeled with the text "heavy metal waste".
In this way, the heavy metals do not go down the drain and I also do not bury any precipitate (which to my opinion is even worse than pouring it down
the drain).
Many other metals salts I simply dispose of down the drain, e.g. iron, titanium, manganese, magnesium, calcium, chromium(III). Metals like zinc,
copper, nickel, cobalt are borderline. If I have a gram or so of metal waste, then I put it in the bottle, if it is minor (only 100 mg or so, or a few
ml of dilute solution in a test tube), then it goes down the drain with a lot of water.
--------------------------------------------------------------
Volatile organics I simply dispose of by letting them evaporate outside on a paper tissue and when the tissue is dry, I put it in the normal household
waste. Having a few ml of e.g. DCM, acetone, chloroform or some other organic evaporate outside does no harm at all.
