I thought sugar needed nitrate added in order to be explosive.
Obviously I don’t know...
Sugar dust is very flammable from what we’re hearing.
Think about it, how quickly does sugar smoke on the stove? Or how easy is it to burn something like cinnamon toast??
What happened at the sugar plant is anybody’s guess at this time. Most manufacturing plants where airborne powder is a factor have large dust extraction systems to prevent explosions like this one.
