some idiot accidentally ignite the heap of BCOL. you must extinguish it using ONLY YOUR STKM2 Saltwater is the best water for extinguishing fires, why?
After evaporating , it leaves salt behind that prevents the coal from burning, sorta like putting sand over fire in real life.
I also use salt water and salt to put out brocken coal..it still burns while buried but no fire shows until the coal loses all life turning into fire. I use it when my coal blimps burst into flames.
