This story, out of Austin, TX, is about a tortilla-chip maker that had changed it handling of waste chips had the ‘pile’ of old chips (stored behind the office) burst into flames. Apparently as firefighters (AFD Facebook statement) were putting out the burning boxes, others not on/in fire were lighting themselves in as f-fighters watched! Three days later, same thing again with the spontaneous flames of boxes of old chips that were left from last fire. :smack: This time, AFD soaked everything left there.
Why the start of combustion??? Things I know and understand, fwiw: corn silos going boom because of high dust levels and a spark, and a substance’s actual temp for combustion (etc). But what is going on here?
