Hi folks

I have 300 gallon tank formerly filled with gas oil / 35 sec heating oil /
medium diesel (not sure
of the U.S. terminology). The only way I can remove it is by first cutting it
up. Any suggestions / comments
so as to do this safely?

Cutting up a heating oil tank is relatively easy and safe since heating
oil / #2 diesel fuel isn't particularly volatile, however that is not
the issue. The issue you will have is disposing of the oil coated metal
pieces and worse yet the thick layer of sludge that is invariably on the
bottom of the tank. The US had less stringent regulations on suck stuff
than the UK and even here it's generally not worth the trouble of trying
to remove and dispose of a heating oil tank yourself. It can be done,
but if you attach any value to your time it's cheaper to have a properly
equipped and insured company do it.
