What everybody is dancing around is "LEL" or "Lower Explosive Limit".

It is that point where the dust volume in the air WILL explode.

An entire industry exists to provide instrumentation to measure "LEL"
for various products.

There are published tables of LEL values and are usually available from
the instrumentation manufacturer.

Been there, done that, but that was a while ago.

No disrepect intended, but I've read dozens if not hundreds of MSDS
and had some training as well, and I have never seen a reference to
LEL/UEL that was not for gas or vapor concentration in air. In fact,
for dust any LEL would vary with the particle size.
