Different mold types on wood
My job consists of building 13 foot crates with pre-cut wood, however sometimes this wood sits on the side if too much is ordered, after a while when it finally comes to the floor it has all kinds of mold ranging from green, black, and some sort of white web like substance, some of the wood turns blue/purple/pink aswell, is any of this harmful to breathe in or use? (No pictures available since I can't my phone on the floor)
