That sounds like it creates some kind of self sustaining reaction With something inside the body.

Has anybody thought about that?

I did metal oxide digestions for many years using aqua regia with HF (49%). I knew the MSDS on hydroflouric top to bottom. I remember one of the treatments was "debridement". That is, cut off before it burns deeper.

If you don't want to do that, have some Calgonate gel on hand.

Time for a 21st century counter-history book (vs. the Rachel-carson Silent Spring propaganda). Will have to be emotion-laden in the proper way.

It is actually one of the weaker strong acids.

What HF does, however, is kill the nerve cells as it burns it’s way into you so you feel no pain. All you notice is a white spot on your skin, i.e. dead tissue.

HF reacts with the calcium in your body and can cause ion imbalances that can cause your heart to stop. If it reaches your bones it will uptake the calcium and cause the latice structure to fail giving you soft bone.

What is the form of fluoride that they like to poison water supplies with?

45 posts and not one mention that HF acid is commonly used in wheel cleaners.

HF, according to a YT documentary I saw about the Toronto municipal water supply system. They said so explicitly, and showed the metering valve slowly admitting HF into the supply stream after purification steps were complete.

There are two effects from an acid burn:

a) the physical destruction caused by the chemical reaction between the acid and the tissues of the body. This will follow the same rules as all other chemical reactions, so 1 gram of acid will reduce 1 or a few grams of tissue to other chemical substances.

b) many of the newly created chemical substances will be highly toxic, and will be spread through the body by the blood and lymphatic system, just like snake venom.

It's the toxic byproducts that can kill from a small spill or cause sepsis-like blood clotting in a limb resulting in amputation, again just like snake venom.

So, the nastiest form of fluoride is what they put in municipal water. For our benefit, of course.

> Yeah, this is the stuff you want if you need to get rid of a body with no chance that there will be anything left, not even the teeth.

Great example of it in Breaking Bad (the bathtub scene).

Isn’t this the stuff that’s only neutralized by calcium? Which is why it continues to burn and eat away all the way to the bone?
H2S?

This is likely true for many types of chemical burns whether from an acid or a base. However, you should do a little more research on HF and hydrofluoric acid... the mechanisms are not the same.

Yes, you are correct. The mechanisms by which it causes damage to the body are a little more complicated however.

...because no-one has ever died from a gasoline engine?

I mean, the risk described is real, and will grow as the cars become more common. But 33,000 people die from operating cars each year, and has even one person died from HF exposure to date? Imagine all the folk around here riding their horses, when someone comes along talking about making horseless carriages that rely on controlled gasoline explosions!

I used to work in the North Slope oil fields in Alaska as a medic. Encountered one fellow who had been mixing a solution of HF and HCl with inadequate PPE a few months earlier. He managed to soak his lower pant legs and thought nothing of it due to inadequate training. The acid started dissolving the tissue between his ankle bones and his Achilles tendon. By the time it was arrested after hospitalization, multiple surgeries, and lots of IV Calcium he had developed a permanent hole in his lower leg. When I encountered him he was back working for the same company. That’s when I realized he was none too bright.

Same here... HF reacts when it penetrates to bone.
Aqua regia was fun too. Cleaned gold out of bonding
tools.

But it is not H2S... it is HF ( hydrogen fluoride) dissolved in water.

I was mainly distinguishing between primary effects (the burn) and secondary (diffusion of compounds released by the primary).

From reading the article, HF is particularly nasty because the primary reactions cause the acid to break down and release fluoride anions that readily diffuse through tissues causing a host of additional problems when they hit something with which they will react, like bone or nerve cells.

So it's almost like an acid the breaks down into a nerve gas. I would imagine inhalation of even a little HF gas would cause death, as the anions would be directed almost immediately to the brain. Yuck.

Fluorosilicic acid (H2SiF6) is the most commonly used chemical to fluoridate municipal water supplies. Sodium fluoride is the most common chemical used to add fluoride to toothpaste.
