Big rust

Hambro particle board manufacturer burned down in 2013. It was an enormous fire and surprising that the forest behind it didn't ignite. The newspaper article (link, next photo) stated that most of the mill was built of wood. Add piles of sawdust and that's a fire just waiting to start. I read elsewhere that in "the old days" of the lumber industry mill fires were common and usually burned them to the ground. Some mills burned again after being rebuilt.
