hopefully all of those links will take you to the CSB report on the
West Texas explosion

You can also go to

csb.gov and select completed investigations and scroll down about 10
reports

from the report

CSB identified two factors or conditions that likely contributed to
the intensity of the fire and detonation: (1) the contamination of
FGAN with materials that served as fuel and (2) the nature of the heat
buildup and ventilation of the FGAN storage space.

CSB collected data on similar incidents at the facilities in Bryan,
Texas, and Athens, Texas. These incidents demonstrate that an FGAN
pile can experience a major structure fire without detonating.
