When removing fuel tanks (the 500 to 10,000 gallon underground type), they
are inerted with dry ice and large sections cut out of the top with a
cutting torch. The gasses released from dry ice melting are supposedly
inert enough and heavy enough that they will remain in the bottom of the
tank while they fill it up and cannot support combustion (even though liquid
gasoline in some amounts are almost always remaining) while a cutting torch
is applied to the top. I would still tend to go to a professional on this
one, I don't like things with the potential to make a _big_ boom in my face.
