Grain dust is a by-product of the grain handling and milling process, is highly combustible and can burn or explode if enough becomes airborne or accumulates on a surface and is exposed to an ignition source.

According to the Nestlé Purina website, the Flagstaff plant employs about 250 workers and produces 1,000 tons of dry dog and cat food a day.
