Patrick,
Anecdotal evidence does not support the facts that I conveyed in the
attached memo. There is a have a horror story for every type of auto repair
out there, as I'm sure most of the people on this page can attest. The
advice I offered was what the Fire Marshall requires for handling tanks that
could take out a city block. Keep in mind that my own wife is standing in
the area while the tank is coming out of the ground.
There is a lot more to it than just dumping dry ice in the tank. I advised
Steve to call the fire dept., who would probably tell him to pay a
professional... not someone who has never been trained to handle gas tanks.
I have no problem with cutting my own gas tank to pieces after it had been
cleaned and had dry ice inserted into it. However, I used to work in a
muffler shop welding around FULL gas tanks. Dangerous? You bet! Proceed
with caution? Yup! Would I let a gas station weld on my car or bring in a
leaking gas tank while welding was going on? Hell no!
"Experiment" was not a word I used. However, you make a very good point that
one can never be too cautious with gasoline. All of us should think twice
before we attempt to repair a fuel problem or weld in a confined space. The
only time I have ever been hurt while working on auto's (or anything else)
was when I was ignoring my own safety or someone else was doing the same.

Some 40 plus years ago, three brothers that had just recently finished high
school bought a service station that was equipped with three service bays,
that were "pits" like in the fast oil change stations you see today. They
had a car come into the bay that was leaking gasoline. One of the boys was
trying to fix the leak, while the other was using an acetylene torch in the
opposite end of the pit on another car. When the (FUMES) and not the liquid
drifted to where the torch was burning there was a flash burn that only the
vapors burned. It lasted about as long as you can blink. the car did not
blow up and burn. The result was the whole station was involved in that
flash burn. There were the two brothers that were in the bottom of the pit
that were inhaling the fumes, and the flash entered into their lungs where
the insides of their lungs as well as their entire bodied were charred. Not
enough to kill them instantly, but enough that they lasted two weeks before
dying.
The third brother was standing outside by the bay doors and had his entire
clothing burned from him. He was the only survivor, the oldest, and he
probably still has nightmares about that disaster. I would think twice
about experimenting with a torch around a fuel tank. I would even have my
fears around someone that says, HE CAN DO IT. Good luck, and have a safe
trip.
