Removal of amalgam: it depends on the amalgam in question used (not always the exact same just like "gold" fillings) and how its condition is after years of use. Views on this may vary depending on country/continent and dentist.
Let's agree it is wise not to use amalgam in new fillings. Cumbb, I am glad with DKTP and BMR as I have met various polio victims in my youth. The HPV vaccine is also very effective with 93% success rate. Not so glad with semi-forced/"voluntary" ineffective Covid vaccinations and their sometimes severe side effects.
All off topic so let's move on.

Always look for alternative solutions.
Always carefully weigh the dangers.
Have the complete tooth removed (Ugh).
Oh, is it that Wisdom Tooth or Molar at the back of your mouth?
The dentist might warn you that if his pain killer needle hits a nerve back there, you may have a cheek that [always] droops, or other permanent complications.

Bravo!
That is the paradigm of recent politics/ western nations... Create a scare and profit from it-
So there are potentially dangerous substances on this planet... Really?? Weve been briefed on that...
So dont lick your fingers or breathe the vapors- common sense
Life causes death... Most of us as kids grew up not wearing seat belts...
Yet here we are, just live smart- the end

Hi retailer
Thank you comments. I must admit I did not view any of the documents cited on the warning posted in the HRSA (Historical Radio Society of Australia) and after your post have done so, a much better legal mind than mine would be required to fully understand the implications.

I contacted the President of the HRSA and after some correspondence with him am in agreeance with the groups decision to dispose of the tubes containing mercury in the HRSA valve-bank. Apparently there is no statute of limitation of potential liability with this issue.
The safe handling of all hazardous waste is a responsibility we all share; how we deal with it is to some extent our choice.
I have some old gas lamp mantles containing thorium for testing my geiger counter, I guess these could be considered a hazard by some. Thorium containing tungsten welding rods are freely available and also work well as a radiation source.

They are indeed a famous Raymond Loewry (father of industrial design) design. If it's round, you can't hang it crooked. 😀
Now I know what happened. 5th grade teacher had a small jar of the stuff. He used to let us stick our fingers into it - or I distinctly remember doing that and how heavy it felt. Inevitably it spilled and the school janitor simply came with his floor mop; I also remember seeing it all mixing in with dust and dirt from the floor and stuck in the fibres of that mop. Another day went by in the 1960s...
Nowadays they'd have a heart attack. Evacuate the building. Class-action lawsuit. Teacher loses job. I liked him. He made me and Doug punch each other in the arm until one of us collapsed for fooling around in class. I caved in first - it started to really hurt!
Another classroom memory; teacher (maybe same one) had red mercury oxide, which he proceeded to heat with a bunson. The idea was to observe mercury droplets forming as the oxide cooked. I remember seeing them form.
We burnt magnesium in classroom. The teacher threw cadmium in the school pond. Different times 😉
We did an experiment that required potassium cyanide at school, and we all had to go up to the teacher's desk and collect our potassium cyanide crystals on a spatula and walk back to our benches. Then 1 year later in University, and I had to do the same thing except I had to go to a special counter, collect a sealed test tube of the crystals, and sign the official poisons register. Schools are usually 1 generation out of date.
When I ordered 5 grams of thermal glue a few years ago it was double packed in a large carton box packed in a very large carton box. I had to sign a few documents.
Absolutely did not associate the large package with the tiny syringe thermal glue I ordered 🙂

I shudder to think, but we used to get a copper halfpenny and some mercury on our palm and rub them together, and rub them, and rub them. Eventually the mercury would smear all over the copper coin and transform it into a "silver shilling". It was alchemy!

Same here. We had a teacher in 3rd or 4th grade that had a jar full of mercury. It was available for kids to play with until they figured out that we were coating copper pennies and then passing them as dimes in the school cafeteria. That was in 1960 or 61 when a school lunch cost a quarter.
And so your life of crime started 😀.
Unfortunately, I missed getting to play with all the poisons. By the time I got to it, no mercury or cadmium. So we threw sodium in the pond instead.
I have replaced all CFLs with LEDs, except the 48" ones in the den.
My I-177 uses an 83 rectifier. I have one spare. All other mercury rectifiers are gone.
I had a pound of mercury up until about 5 years ago. I turned it in to a Hazardous Waste disposal company.
Our local E-Waste drop off has a place for CFLs. I took mine there. They probably ended up in a dump.

Yes, were the times when in the cinemas people smoked and the whole room was saturated with smoke and the light coming from the projector was like a dazzling blade in the air...
There was a thick curtain of smoke in the room and yet it was considered normal and nobody seemed to notice it.
No one thought that smoking was harmful to health and no one knew about health risks, except perhaps tobacco multinationals. 🙄
And the same happened for many other things, just as an example about the amount of X-rays considered not dangerous.
Those were the times when the world population was 4.4 billion people.
Today we are about 7.8 billion, and with Public Health one does not mess around.
And one can’t say anymore that he doesn’t know. 😉

Anyone remember the pedoscope?
I remember as a young boy in the 1970s being frightened to death by one.
Not because I was aware of the dangers, just because it was a scary looking machine.
Perhaps a lucky escape having my feet measured manually, or perhaps my feet would have been less cramped with better fitting shoes?

The wiki article on the pedoscope is informative and frightening. Machines sold in the USA produced 10 times as much power compared to the UK. Can’t believe they were used until the 1970s.
