Dear all,
Can anyone confirm if a chemcially inert, non-flammable dust could be at risk from explosion given the right circumstances i.e. the correct dust/air mixture in the prescent of a ignition source.
Or, as I believe, due to it being non-flammable, it would not be possible to ignite a dust cloud and therefore cause an explosion.
Your thoughts please?
Thanks

It depends how you define flammable. If this dust is truly unable to react with the gases in the atmosphere, then it is not possible to create an explosive mix. Perhaps you could tell us what it is?

Hi FLic,
Its a material used as a flame retardent and electrical insulator.
Its called Mica Powder (95% Potassium Aluminium Silicate and 5% quartz powder.
It can cause pneumoconiosis if prolonged unprotected exposure was to occur.
Hope this helps a little, my chemical background is somewhat limited although I do have experience of DSEAR/ATEX
Thanks

As those components cannot oxidise further (as far as I am aware), they cannot form an explosive mixture in air.

Thanks for that Paul much appreciated.
I think I need to dig out my chemistry notes from Uni.................!
Cheers

I agree, silicates do not oxidise further and quartz is silicon dioxide - which also cannot oxidise further.
No possibility of explosion.
