I suspect you are right - the fireproofing stuff tends to have free
fibres rather than the more common white asbestos cement board.

If by recently you mean the 1970's then I suppose you are right.
There is a bit too much hysteria these days about removing white
asbestos cement board from everywhere and making a mess in the process,
but loose lagging material was seriously nasty and few people who worked
with it in the pre-PPE days are still around to tell the tale.

Try telling that to Malcolm McClaren - probably the most high profile
mesothelioma casualty as a result of his smashing up and careless
handling of the relatively safe cement asbestos board in his shop.
If there is loose fibre blue or brown asbestos present and there might
well be with insulating fire proof boards then you really want to be
very careful not to raise a dust. Unless you are used to working with
nasty materials for minimum contamination you don't want to do it.
An alternative is to spray the boards in some approved high tack two
part liquid paint that wicks in, cures and binds everything together. I
recall something like that being used on an asbestos lined observatory
dome back in the 1970's to prevent chucks dropping off. The whole lot
was professionally stripped in the 1990's when it became completely
unacceptable to have serious amounts of blue asbestos in the workplace.
(obviously it would no longer be very fireproof)
You might be able to get a modern intumescent paint formulation that has
all the required properties but you are in expensive specialist territory.

It takes up to 40 years to cause noticeable damage. You may still have
shortened your lifespan by careless handling of asbestos dust. It is a
matter of luck, genetics and other potential cofactors like smoking.
