An informed opinion....
It sounds like you were smashing up AIB (Asbestos Insulation Boards). Not the best material for starting a bonfire...

You can skip this bit and go to the final line if you like....

These probably contain Amosite and perhaps Chrysotile. The asbestos content would be up to 25% of the board - maximum.

Although it may have been blue/grey it is very unlikely they contained any Crocidolite (which can be 'blue' in colour).

The control limit is about 0.2 fibres/ml over four hours. Breaking and ripping out boards is about 5 - 20 fibres/ml an hour I think.

You were outside, and you only did it the once so I wouldn't worry too much. I certainly wouldn't lose any sleep over it.

Asbestosis seems to rely on cumulative exposure. It is still legal to use/mine asbestos in some countries. So make of that what you will.

In short - don't worry.
