Default Cutting furnace oil tanks

Maybe this should be in the 'un'fabrication section. Although as it may be an unsafe process, (proceed at own risk!!) Inthought maybe it would work here.

I have 3 or 4, 200 gallon steel oil tanks from oil furnaces. They are all going to scrap, but to donso they must be cut open to be accepted by the scrap yards here.

I've always done it before with a sawzall, was wondering about an abrasive wheel instead.

What's everyone's thoughts on the flammability/explosion possibilities or hazards? Stick to the sawzall?

If you fill them with water first, you can cut them any way you want.

I never had any problem with fuel oil tanks cutting with a torch. The fuel oil take quite a bit to get burning usually. Gasoline storage might be a little more exciting.

One other option if you want to be more cautious, run a hose into the tank from your car or lawn mower motor exhaust. You want to remove the excess oxygen to reduce the chance of combustion. Water does the same thing. Once you get several holes in it, the worst it can do is flame out the holes, but no boom .

This has been my experience so far, but proceed at your own risk. Your results may vary.

If you do the water, try cutting the top first. And try to keep the water away from the electric cut off. I am also told that water and electricity does not mix well, but I prove that wrong every time it rains at my work too! There is going to be that one time though someday.

Cut one up a couple of weeks ago, to make a nice trash burner.
Sawzall to cut opening in end, once it has a 1' sq opening, I used the plasma.

Grey, Go with Brian's idea and put exhaust into it and leave the engine running while you cut. Removing one of the legs of the fire triangle is a sure way to prevent explosions.

I'll just need to find a hose to use, should be something kicking around.

Going to use the quick cut and open up one side on the tank so I can use them as scrap bins for the cleanup going on. Figure they can do double duty that way. Torch a couple holes and sit them on the trailer, and let them pick the hole works off at the scrap yard.

I have used the exhaust suggestion also with safe results.. Have soldered gas tanks that way also..

The ends of oil tanks make great forge bodies. If I was closer I'd come grab one from you..

Drums, tanks, gas bottles etc etc , they all get purged with air if possible, pressure washed with water and soap if possible and always get purged with exhause gas's while cutting.

I make sure the truck is warmed up and the choke is done doing it's thing. lol

I have a couple tanks of nitrogen for help in the shop and as a pressure source for a pressure building pump for my PCP's (which for those in need to know this is not a drug but Pre-Charged Pneumatic air guns).

My use of Plasma cutting is my preferred choice of cutting these things. Or the band saw when possible.
