Indeed. The fluoride easily penetrates the skin and disturbs electrical functions in the heart and other parts of the nervous system. The exact
mechanism by which, I'm not sure.

Another thing I have in mind is thermal decomposition of HFC refrigerant. It isn't hard to do in presence of catalyst and water. When the coil in
refrigeration compressor burns out under refrigerant vapor due to a short or an overload, HF level can reach such a level that it can make the tainted
refrigeration oil a chemical burn hazard.
If you run it through glowing hot copper mesh in a glass tube and run the output through cold water, you might get a fairly good deal of HF.

Hypocalcemia is a large part of it: HF precipitates Ca<sup>2+</sup> as CaF<sub>2</sub> in cells, causing these cells to die
very quickly. Hence very painful burns that heal only slowly. Considerable exposure leads to slow and agonising death.
This is why having calcium gluconate at hand as an antidote is recommended: large amounts of it can bind the HF/F<sup>-</sup>, reducing
the damage.

How bad would a 3% solution be.

Still bad enough to what is necessary to prevent any getting on your hands or eyes but of course much less dangerous than 40 % or anhydrous HF.

Might buy some 3% HF at Home Depot.
