Bulk gasoline storage questions

..........Making damn sure the barrel has no explosive vapors in it before welding.

Easier way: use a screw clamp on the drum, and a 10ga copper wire clamped to a metal rod driven into the ground. Like your house meter box has. Or just have a driven ground rod, and use a cable with jumper clamps on each end as a portable ground.

Probably. Still a good idea to use a ground rod and wire. It's cheap insurance.

BTW, the various videos of women having flash fires at gas station pumps has been shown to NOT be their cell phone use, it's generally due to.......get this, their PANTY HOSE.

Which is why I agree that ALL women, who might need to refuel their vehicles, should wear NOTHING under their dresses - simply to limit the chances of spontaneous combustion!!! :lol: :lol: :lol: :lol: ;) ;)

If someone wants to to take the prudent step of storing fuel, and be equally prudent in purchasing the transfer and storage particulars, rock on.
If you're going to do it half-assed, I think the appropriate advice is "Suture self".

There are any number of commercial enterprises, including Northen Tools, who sell proper equipment for moving, storing, and transfering fuel, drums, etc. I would avail myself of their products before trying to do things on the cheap, but mainly because I know the price of large-scale skin grafts at the burn unit.

Also, in my experience, most gas stations have no frickin' idea what you're pumping gas into, provided their product is paid for, and don't tend to slither out from behind the registers long enough to have anything to say, but I'm in a busy urban area with clerks looking like they'd need help to spell GED, let alone in English. Mayhap the hired help in rural areas are bigger busybodies more conversant in DOT and Hazmat regs, so adjust your actions accordingly.

Perhaps one of the reasons I ask the question.

The plastic or the steel drums, if properly sealed / vented are not significantly different then the dot containers.
3/8 in plastic / 1/8 in of steel vs 1/4 in of steel /aluminum is not the issue, proper venting and fume removal is the key to not making a bomb. Well that coupled with proper grounding.

In other words, if they go bang, the container construction will have no meaningful difference in explosive containment between the options.

I see no difference other than venting between the options. Please help me understand where I am wrong.

Good grief. Aesop has been here for less than a week, and I am already agreeing with him on something. I'm expecting it to start raining frogs any minute.

My friend with the Subaru powered Bearhawk built a fuel trailer for hauling mogas a few years ago. IIRC, he used a commercially made tank just under the size that requires CDL/Hazmat in this state, and it also has plywood sides that conceal the contents. If you drive by and see it in his driveway, it just looks like many other junky homebuilt trailers with plywood sides and top. I don't think any signage requirements apply to it, but if there were, you could make something that is hung on when the trailer is in use on the road. IIRC, he's got some kind of electric pump installed. That way he can stand on a ladder and fuel his airplane (high wing, with wing tanks) without needing to get somebody to work a manual pump.

Uh, negatory. You prevent a gasoline tank from having a vapor explosion by keeping it full, and letting it build up vapor pressure to a nonexplosive/combustive level. If you continuously remove the fumes through excessive/forced venting, it will never build up to that non-combustive vapor pressure, and oh by the way your fuel will eventually evaporate away. The purpose of the vent is to allow for thermal expansion/contraction, and replacement of the fuel with air as the fuel is pumped out of the tank.

I like steel containers because of 1) ease of grounding, and 2) overall strength and durability, assuming proper construction. A 55 gallon drum made of thin sheet metal, with rolled seams is probably not the best construction for long term storage and transport of fuel. I'd certainly prefer it to a poly drum for temporary storage or transport of extra fuel, but for a long term piece of equipment I'd rather have something better.

I have almost entirely purged plastic fuel containers from my life following an incident that resulted in an ER visit a few years ago. Once I get some metal cans that are smaller than my 5 gallon NATO cans, the last of the plastic ones that I use for my lawnmower, chainsaw, etc will be going away permanently.

At Rancho del Termite, diesel and gasoline are stored under pole sheds, in steel tanks that have their own steel skids welded on, with pad eyes on the skid runners for attaching chains/straps. They can be dragged around by tractor, or winched onto trailers. Both have manual hand pumps, and the gasoline one is grounded. They are approx. 250 gals in size.

YMMV.

looking at used semi fuel tanks. Perhaps to mount on the trailer thing or perhaps not. Still evolving this idea (and comparing it to my bank account).
