Also I believe that the report or an abstract of it was published in a
Tripoli Report from when Bruce Kelley was publishing it.I am sure it's in
my house somewhere but can't remember where at the moment.

Bruce, please don't take this the wrong way, and I certainly don't mean
to be rude, but can you back that up with hard data? Test reports, for
example? I think you are probably right, but I need some evidence to
support that.

Don't be concerned if more than 15 micron particle size or when mixed

Thank you, that is indeed interesting.
I may as well tell you what I'm specifically interested in, as some on
this list may know the information I am looking for, or know where to find
it.
I have just discovered that there are 5 x 200kg drums of AP being
stored across from my office. I am aware that AP's propensity to
detonation is dependent on the particle size, but can find no definitive
information on the interweb. For example, I was looking to buy a sample of
AP from Sigma Aldrich as a standard for analysis, and noticed that
according to the MSDS it is listed as H201 Mass Explosion Hazard (or R3
Extreme Risk of Explosion in the old R phrases) (see link below). Sigma
Aldrich give their AP particle size as > 45 micron.

Other information I can find seems to say that different states in the
US classify it differently, the US Army classifies it as 1.1 at < 15 um,
etc etc...
Wikipedia says that the AP involved in the PEPCON explosion was
nominally 200 micron, so fairly coarse, in fact comparable to the drums in
the store opposite my office. I am trying to confirm that figure for 200
um as I am wary of trusting Wikipedia, hence why I'm trying to find the
official accident reports.
So, anything anyone knows about whether I should be concerned about it
or not would be welcome...
