In the 60's in Special Forces the "dust initiator" explosive was well known...a small explosive in a sack of flour in a closed space would provoke a massive explosion.
That is the problem in all factories producing dust...I toured textile factories in the mid 1970's in Pakistan where dust and consequently the threat of a catastrophic event was a major problem. So dust would seem to be the issue...not necessarily black powder. But of course...defer to the experts.
