Your father was quick thinking and probably had some very good training.
I worked in a large R&D lab, never knowingly near hydrofluoric acid.
But spend endless hours in safety classes for almost everything.
Some very nasty stuff.

“electric vehicles and electronic gadgets”
I’ve wondered about the total tonnage of lithium used in cars versus its use in electronic gadgets.
If you can find an example of HF being used to add fluoride to a municipal water system... please provide a link.
I would assume that currently electronic gadgets are still using the most... But since you are talking about grams vs hundreds to over a thousand pounds per battery... It probably will not take that long for electric vehicles to take the big prize.
The CFO of Rivian said recently that probably less than 5% of the infrastructure currently existed to produce the amount of batteries that would be needed by electric vehicles in ten years. My guess is that it will never exist.
Ah yes HF acid.
Also used in refining gasoline
#4 No wonder food in teflon coated cookware tastes funny : )
I will stick to stainless steel.
“Teflon can generate significant concentrations of HF if overheated (above 500°F)”
This is another reason not to get a electric car.
Imagine millions of batteries leaking in landfills or in your car.
Electric cars are a fire hazard and will dissolve you too : )

#6 “Teflon can generate significant concentrations of HF if overheated (above 500°F)”
FTA: A colourless liquid, hydrofluoric acid is highly corrosive – it can dissolve glass! – and is extremely toxic.
There must be a very high risk of contamination in the event of a severe automobile accident/impact that damages the battery: the potential for the stuff to be sprayed for some distance; not to mention the consequences of it coming into contact with hot surfaces.

Early on I worked with the fellow who was the engineer responsible for the tin plate line for IC packages. The acids were just sulfuric and nitric but he had kind of a casual attitude. Never got anything resembling a bad burn but one day he put his hands in his pants pockets and the pants totally disintegrated. So much for that pair of work pants.
just be sure to put the body in a large plastic tub and not an actual bathroom enamel-coated iron tub ...
Reminds me of a drilling project at the Tyrone mine in NM, around 1993. One site was adjacent to a dump where sulfuric acid solution was being applied with sprinklers. The mist was drifting over the rig all day, and everyone’s eyes were burning. When I washed the clothes I had been wearing, they just fell apart.
At Intel, the safety demonstration included dipping chicken
parts in hot sulfuric. Came out blackened. After a few complaints it changed to a white cotton tennis shoe.
Same result.
Not just any plastic tub either, it has to be the correct kind or it won’t fare any better than cast iron.
