How to cut open an oil tank?
I'm digging up an old underground 450 gal oil tank. The dump will accept it as long I get all the residual oil out and cut an opening "wide enough to stick your head in" so the dump guy can look inside.
I've got a 4" angle grinder I was planning on using to cut it open, but I was wondering if it would ignite the oil. Anybody know or have a different way to cut it?
