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?

Regards
Rob

I've done three of them, use thick sawzall blades, scrape the sludge out and
bring it to a municipal oil recycling area, and the metal pieces to the
dumps. Check your local regulations.
